doclaunch time optimization this topic presents a case study of improving an application to reduce its launch time it describes the application launch process, techniques for reducing application loading time, and best practices for writing more efficient javascript applications that offer a good user experience ux attract more users users who have positive impressions of an application return to it and are more likely to recommend it to others if you monetize the application, this can result in greater profit application launch time is the total time from the moment when the user clicks the application icon until the application is ready to use improving the application launch time improves the user experience because application loading is the first experience the user gets of your application, a long loading time can leave them with a negative impression therefore, it is worthwhile to prioritize reducing application launch time user satisfaction drastically decreases as the application launch time increases, as shown in the following figure based on a user survey using this information, a target launch time of around 5-7 seconds satisfies most users application launch process the application launch process can be divided into 5 stages some stages are controlled by the system, but most stages are dependent on application implementation, providing opportunities for performance improvement this case study is based on an application running on a 2015 samsung smart tv video was captured while launching the application on the tv, enabling the duration of each application launch stage to be measured with an accuracy of one video frame noteif you want to test your application in a similar way, make sure that all tests are performed under the same circumstances, such as using the same device with the same network conditions, to reduce the effects of external factors the following figure illustrates the application launch stages, and the time spent at each stage for the case study application the following table describes each stage in detail stage action screen time description 1 application icon click 1 086s time between clicking the application icon to when the smart hub "apps" panel disappears 2 initial loading screen 4 979s time between loading the home page "index html" and calling the window onload method 3 black screen 0 837s time a transition screen is shown before calling the window onload method for samsung legacy platform applications only 4 splash image 0 570s time until the splash image appears the splash image is the first screen shown in the application after calling the window onload method it is usually shown during authentication or while content is loading 5 home page 0 348s time taken to render the home page, fill it with content, and enable user input table 1 application launch stages optimizing launch logic this section assumes that the case study application utilizes a framework the framework contains modules responsible for activities, such as sending ajax requests to the backend server, application authorization in the backend side, and modules responsible for the ui and logic the case study application loading process is illustrated in the following figure the application logic is dependent on the framework setup in stages 2 and 3, load and initialize the framework after the framework setup is complete, start authorization at the backend server with the application logic if authorization succeeds, send ajax requests to the backend server to fetch application data, such as a list of recommended movies to display on the application home page ajax requests are dependent on the authorization step, because they must contain an authorization token wait for the data needed to render the home page, and render it this model is not optimized because the entire framework must be loaded and initialized before the application can start the authorization and content loading processes a possible approach to speeding up the launch process is by rebuilding the application in the following way divide the framework setup into 2 phases in the first phase, load the modules responsible for application authorization in the second phase, initialize the rest of the framework once the first phase is loaded, perform authorization immediately it is only dependent on the xhr object created in stage 1 during web runtime setup multiple ajax requests are merged into 1 request to avoid unnecessary delays the ajax request is dependent on the authorization step for the authorization token when the framework is fully initialized, begin performing the basic home page setup without waiting for the ajax request response stage 3 is eliminated completely by migrating the application from samsung legacy platform to tizen padding time is needed to synchronize the application logic and ajax requests the application logic requires ajax request data to render the home page, but as the requests are asynchronous, implement mechanisms to coordinate the modules, such as events, callbacks, and promises resume the application logic after receiving the response from the server load other parts of application logic, such as required scripts and data, on demand in this way, they do not delay the launch process this flow is more optimized, as many tasks are performed in parallel initially, the application loads only the modules which are necessary for authorization and starts authorization immediately along with other operations, such as loading the rest of the framework, the ui, resources, and content any tasks not required for displaying the home page are postponed to start after the launch process consequently, application launch time is much shorter than before improving launch time the following table lists optimization strategies that can improve application launch time, and the application launch stages they affect optimization stage 1 2 3 4 5

1 and 3 tizen is more efficient than samsung legacy platform migrating the application from samsung legacy platform to tizen can improve its performance significantly enabling prelaunch stages affected 1, 2, 4, and 5 tv web applications in tizen support prelaunching applications can load in the background when the samsung tv is switched on when the user launches the application, it loads more quickly because it has been prelaunched for more information, see prelaunching applications minimizing home page code stages affected 2 and 5 application launch time can be improved by loading and parsing less code at launch when the application launches, load only the html, js, and css code necessary to show the home page other code can be loaded on demand using a library, such as require js, to avoid building and parsing the dom before it is needed loading javascript files asynchronously stages affected 2 and 4 when loading external javascript files normally, the html parser stops while the javascript files are downloaded and executed to avoid the pause in html parsing during download, you can use the defer and async attributes <script src='js/main js' defer></script> <script src='js/scripts js' async></script> using the defer attribute downloads the javascript file in parallel while parsing html the javascript code executes only when all html parsing is complete scripts using the defer attribute are guaranteed to execute in the same order that they appear in the document using the async attribute downloads the javascript file in parallel while parsing html, but when the download completes, the html parser pauses to execute the script the defer and async attributes can be used only for scripts implemented with the script element and src attribute for more information, see the html <script> element handling ajax requests you can improve launch time by optimizing ajax request usage sending ajax requests promptly stages affected 2 and 4 most applications load their content from remote servers and utilize a framework that helps manage the requests however, loading and executing the framework code can take a lot of time to speed up application launch, send the ajax requests needed to display the home page as soon as possible you can send a simple xhr request at the beginning of the "index html" file, before loading the framework xhr requests are asynchronous and do not block any other threads cache the response in a global object, so the application framework can use the data immediately to display the home page without sending the request again parallelizing ajax requests send ajax requests in parallel if they are not dependent on responses from prior requests before each request is executed after receiving a response from the previous one sendrequest1 onsuccess sendrequest2 onsuccess sendrequest3 onsuccess sendrequest4 onsuccess sendrequest5 after the first request authorizes the application after receiving the response, the other requests are executed asynchronously sendrequest1 onsuccess sendrequest2 sendrequest3 sendrequest4 sendrequest5 concatenating ajax requests stages affected 2, 4, and 5 limit the number of ajax requests by merging several requests, if possible the fewer requests there are, the less time it takes to process all of them for example, consider an application that sends 3 requests to display the home page, such as for application authorization, a list of recommended movies, and a list of the latest movies verify whether it is possible to modify the requests and backend in such a way that the response for the authorization request contains the recommended and latest movies as well you can also use this strategy throughout the application to reduce the loading time of other scenes delaying platform and tizen api calls stages affected 2 and 4 many applications make early calls to tizen and platform apis for static information, such as the duid or model code because api initialization is "lazy" the api is initialized only when it is first needed , the first call to each api module takes time postpone api calls until the application is fully started and ready to use, if possible caching api output stages affected 2, 4, and 5 instead of querying the api each time, cache the static output from product and tizen apis in javascript variables consider the following scenarios the total duration of video content is constant during video playback you can retrieve it once and store it in a javascript variable instead of querying the api each time it is needed tv specification parameters, such as the duid or model code, never change you can retrieve the parameters using the api the first time the application is launched and save it in localstorage retrieving data from localstorage is quicker than querying the api using jquery 2 x or higher stages affected 2, 4, and 5 newer versions of jquery are smaller and faster you can also consider using a custom jquery build loading static resources locally stages affected 2 and 4 load static application resources directly from the local file system, by including all application source code, external libraries, and static ui elements, such as css and images, within the tizen package before <link rel='stylesheet' href='https //maxcdn bootstrapcdn com/bootstrap/3 3 5/css/bootstrap min css'> <link rel='stylesheet' href='https //example com/myapp/css/styles min css'> <script src='http //code jquery com/jquery-2 0 0 min js'></script> <script src='https //maxcdn bootstrapcdn com/bootstrap/3 3 5/js/bootstrap min

js'></script> this not only decreases loading time, but can also improve application security and eliminate some application errors caused by network issues minimizing and concatenating code stages affected 2 and 4 the application loads faster when it makes fewer requests to the file system if you do not want to use a lazy loading mechanism to load parts of the application on demand, concatenate and minimize your source code, especially javascript and css files before <!doctype html> <html lang='en'> <head> <meta name='viewport' content='width=1280, user-scalable=no'> <meta http-equiv='content-type' content='text/html; charset=utf-8'> <title>my application</title> <link rel='stylesheet' type='text/css' href='styles/main css'> <link rel='stylesheet' type='text/css'

href='styles/account css'> <script src='js/main js'></script> <script src='js/list js'></script> <script src='js/player js'></script> <script src='js/login js'></script> <script src='js/account js'></script> </head> <body> <div id='menu'></div> <div id='maincontainer'> <div id='helpbar'></div> </body> </html> after<!doctype html> <html lang='en'> <head> <meta name='viewport'

css'/> <script src='js/all_scripts js' defer></script> </head> <body> <div id='menu'></div> <div id='maincontainer'> <div id='helpbar'></div> </body> </html> in some situations, it can be better to concatenate your code into 2 files instead of 1 if the code must be executed as soon as possible, put it into a file that is loaded with the async attribute if the code requires the dom to be ready before execution, put it in another file that is loaded with the defer attribute make sure that the code loads in the correct order to satisfy its dependencies removing obsolete code stages affected 2 and 4 if the application loads any unused source code, whether it is javascript, css, or html, the browser takes time to parse it, build the dom, and search the html code for matching css rules keep your code clean and up to date to avoid unnecessary performance issues caused by obsolete or redundant code for example, when the window onload method is called, calling the unregisterkey method of the tvinputdevice api is unnecessary because no keys are registered other than the default "left", "up", "right", "down", "enter", and "back" keys using sprites stages affected 2, 4, and 5 if your application loads many small graphics, such as icons, button elements, and backgrounds, consider using css sprites css sprites help images load faster by making fewer requests to the file system, which improves overall application performance you can merge all of the icons or background images into 1 large image and use css to set the positions for each element consider the following mouse hover implementation before #mybutton { width 300px; height 100px; background url 'img/button-normal png' 0px 0px no-repeat; } #mybutton hover { background url 'img/button-hover png' 0px 0px no-repeat; } this code is not optimal, as the browser must make 2 requests to the file system instead of 1 additionally, the first time the user hovers on the button, its background will flicker, as some time is needed to request the new image and show it on the screen after #mybutton { width 300px; height 100px; background url 'img/button-sprite png' 0px 0px no-repeat; } #mybutton hover { background url 'img/button-sprite png' 0px -100px no-repeat; } this code is more optimal because it loads only 1 image which takes less time to load, even though its size is bigger mouse hover changes only the background image position, so there is no flickering when switching between the states using pure css stages affected 2, 4, and 5 tizen supports css3, which allows you to create many graphic effects without using image files pure css renders faster and takes less time to calculate its properties, which is especially valuable when animating css elements the following code creates a button using only pure css button { width 180px; height 62px; line-height 62px; font-size 24px; color #fff; text-align center; text-shadow 1px 0 1px rgba 0, 0, 0, 75 ; background -webkit-linear-gradient top, #1e5799 0%, #2989d8 50%, #207cca 51%, #7db9e8 100% ; border solid 2px #fff; border-radius 12px; box-shadow 0px 0px 15px 5px rgba 255, 255, 190, 75 ; } enforcing gpu acceleration stage affected 5 normally, the browser applies gpu acceleration when there is some indication that a dom element can benefit from it css3 allows you to force the browser to render elements with gpu acceleration one of the simplest methods is setting a style indicating 3d transform, even when no real 3d transformation is applied acceleratedelem { -webkit-transform translatez 0 ; } in general, 3d transformations in css force the browser to use the gpu the following declarations can reduce flickering during css transforms or animations acceleratedelem { -webkit-backface-visibility hidden; -webkit-perspective 1000; } for more information, see an introduction to css 3-d transforms and increase site performance with hardware-accelerated css optimizing javascript code follow a reliable and consistent coding standard and style for javascript, as it makes the code easier to write, easier to read, improves its maintainability, and makes it less error-prone the following section presents javascript best practices that are frequently used in the web community caching dom element references searching the dom tree is a resource-hungry operation if there are dom elements on which you perform operations frequently, store them in javascript variables to avoid repetitive dom traversal prefer var elem1 = document getelementbyid 'elem1' ; elem1 innerhtml = 'lorem ipsum dolor'; elem1 classlist remove 'class1' ; elem1 classlist add 'class2' ; var $elem2 = $ '#elem2' ; $elem2 html 'lorem ipsum dolor sit amet' ; $elem2 addclass 'class3' ; avoid document getelementbyid 'elem1' innerhtml = 'lorem ipsum dolor'; document getelementbyid 'elem1' classlist remove 'class1' ; document getelementbyid 'elem1' classlist add 'class2' ; $ '#elem2' html 'lorem ipsum dolor sit amet' ; $ '#elem2' addclass 'class3' ; it can be helpful to store references to frequently-used dom elements in a global object for example var domelementscache = { eldocument window document, elhtml window document documentelement, elbody window document body, elhead window document head, eltitle window document getelementbyid 'title' }; domelementscache eltitle innerhtml 'my title' ; avoiding slow jquery selectors jquery selectors work slower than native ones if application performance is critical, consider replacing jquery selectors, for example id selector //jquery var elem = $ '#myelem' ; //native js equivalent var elem = document queryselector '#myelem' ; class selector //jquery var elems = $ ' class1' ; //native js equivalent var elems = document queryselectorall ' class1' ; tagname selector //jquery var elems = $ 'span' ; //native js equivalent var elems = document queryselectorall 'span' ; $ find //jquery var elems = $el find ' target1, target2, target3' ; //native js equivalent var elems = el queryselectorall ' target1, target2, target3' ; using native methods native javascript methods are faster than wrappers from different libraries in some cases, it can be helpful to use them instead of library methods var myarray = [1, 2, 3]; //underscore _ each myarray, function val { console log val ; } ; //jquery $ each myarray, function val { console log val ; } ; //native js equivalent for var i = 0; i < myarray length; i++ { console log myarray[i] ; } removing console logging extensive logging decreases application performance, because each console log method call blocks the javascript thread in the browser other logging methods, such as the console warn , console info , console error methods, behave similarly to improve application performance, remove log methods in the final build you can use a logger utility to easily switch logging on and off open source libraries, such as woodman, are available, or you can write your own logger, such as the following example // global object for storing application configuration var applicationconfig = { debugmode true //enables logs in application }; // logger object factory var logger = function { var logger = {}; if applicationconfig debugmode === true { logger = { log function { var args = array prototype slice call arguments, 0 ; console log args ; }, info function { var args = array prototype slice call arguments, 0 ; console info args ; }, warn function { var args = array prototype slice call arguments, 0 ; console warn args ; }, error function { var args = array prototype slice call arguments, 0 ; console error args ; } }; } else { logger = { log function {}, info function {}, warn function {}, error function {} }; } return logger; }; // usage // for development and debugging var applicationconfig = { debugmode true }; var mylog = new logger ; // initializes logger mylog log 'test' ; // outputs 'test' to console //for production var applicationconfig = { debugmode false }; var mylog = new logger ; // initializes logger mylog log 'test' ; // does nothing importantnever override console log or any other native function overriding native objects is a bad practice in javascript, as it can lead to unexpected behavior and introduce defects that are very hard to debug optimization results the principles described in this guide were applied to several samsung tv applications, as listed in the following table

concatenate your code into 2 files instead of 1 if the code must be executed as soon as possible, put it into a file that is loaded with the async attribute if the code requires the dom to be ready before execution, put it in another file that is loaded with the defer attribute make sure that the code loads in the correct order to satisfy its dependencies removing obsolete code stages affected 2 and 4 if the application loads any unused source code, whether it is javascript, css, or html, the browser takes time to parse it, build the dom, and search the html code for matching css rules keep your code clean and up to date to avoid unnecessary performance issues caused by obsolete or redundant code for example, when the window onload method is called, calling the unregisterkey method of the tvinputdevice api is unnecessary because no keys are registered other than the default "left", "up", "right", "down", "enter", and "back" keys using sprites stages affected 2, 4, and 5 if your application loads many small graphics, such as icons, button elements, and backgrounds, consider using css sprites css sprites help images load faster by making fewer requests to the file system, which improves overall application performance you can merge all of the icons or background images into 1 large image and use css to set the positions for each element consider the following mouse hover implementation before #mybutton { width 300px; height 100px; background url 'img/button-normal png' 0px 0px no-repeat; } #mybutton hover { background url 'img/button-hover png' 0px 0px no-repeat; } this code is not optimal, as the browser must make 2 requests to the file system instead of 1 additionally, the first time the user hovers on the button, its background will flicker, as some time is needed to request the new image and show it on the screen after #mybutton { width 300px; height 100px; background url 'img/button-sprite png' 0px 0px no-repeat; } #mybutton hover { background url 'img/button-sprite png' 0px -100px no-repeat; } this code is more optimal because it loads only 1 image which takes less time to load, even though its size is bigger mouse hover changes only the background image position, so there is no flickering when switching between the states using pure css stages affected 2, 4, and 5 tizen supports css3, which allows you to create many graphic effects without using image files pure css renders faster and takes less time to calculate its properties, which is especially valuable when animating css elements the following code creates a button using only pure css button { width 180px; height 62px; line-height 62px; font-size 24px; color #fff; text-align center; text-shadow 1px 0 1px rgba 0, 0, 0, 75 ; background -webkit-linear-gradient top, #1e5799 0%, #2989d8 50%, #207cca 51%, #7db9e8 100% ; border solid 2px #fff; border-radius 12px; box-shadow 0px 0px 15px 5px rgba 255, 255, 190, 75 ; } enforcing gpu acceleration stage affected 5 normally, the browser applies gpu acceleration when there is some indication that a dom element can benefit from it css3 allows you to force the browser to render elements with gpu acceleration one of the simplest methods is setting a style indicating 3d transform, even when no real 3d transformation is applied acceleratedelem { -webkit-transform translatez 0 ; } in general, 3d transformations in css force the browser to use the gpu the following declarations can reduce flickering during css transforms or animations acceleratedelem { -webkit-backface-visibility hidden; -webkit-perspective 1000; } for more information, see an introduction to css 3-d transforms and increase site performance with hardware-accelerated css optimizing javascript code follow a reliable and consistent coding standard and style for javascript, as it makes the code easier to write, easier to read, improves its maintainability, and makes it less error-prone the following section presents javascript best practices that are frequently used in the web community caching dom element references searching the dom tree is a resource-hungry operation if there are dom elements on which you perform operations frequently, store them in javascript variables to avoid repetitive dom traversal prefer var elem1 = document getelementbyid 'elem1' ; elem1 innerhtml = 'lorem ipsum dolor'; elem1 classlist remove 'class1' ; elem1 classlist add 'class2' ; var $elem2 = $ '#elem2' ; $elem2 html 'lorem ipsum dolor sit amet' ; $elem2 addclass 'class3' ; avoid document getelementbyid 'elem1' innerhtml = 'lorem ipsum dolor'; document getelementbyid 'elem1' classlist remove 'class1' ; document getelementbyid 'elem1' classlist add 'class2' ; $ '#elem2' html 'lorem ipsum dolor sit amet' ; $ '#elem2' addclass 'class3' ; it can be helpful to store references to frequently-used dom elements in a global object for example var domelementscache = { eldocument window document, elhtml window document documentelement, elbody window document body, elhead window document head, eltitle window document getelementbyid 'title' }; domelementscache eltitle innerhtml 'my title' ; avoiding slow jquery selectors jquery selectors work slower than native ones if application performance is critical, consider replacing jquery selectors, for example id selector //jquery var elem = $ '#myelem' ; //native js equivalent var elem = document queryselector '#myelem' ; class selector //jquery var elems = $ ' class1' ; //native js equivalent var elems = document queryselectorall ' class1' ; tagname selector //jquery var elems = $ 'span' ; //native js equivalent var elems = document queryselectorall 'span' ; $ find //jquery var elems = $el find ' target1, target2, target3' ; //native js equivalent var elems = el queryselectorall ' target1, target2, target3' ; using native methods native javascript methods are faster than wrappers from different libraries in some cases, it can be helpful to use them instead of library methods var myarray = [1, 2, 3]; //underscore _ each myarray, function val { console log val ; } ; //jquery $ each myarray, function val { console log val ; } ; //native js equivalent for var i = 0; i < myarray length; i++ { console log myarray[i] ; } removing console logging extensive logging decreases application performance, because each console log method call blocks the javascript thread in the browser other logging methods, such as the console warn , console info , console error methods, behave similarly to improve application performance, remove log methods in the final build you can use a logger utility to easily switch logging on and off open source libraries, such as woodman, are available, or you can write your own logger, such as the following example // global object for storing application configuration var applicationconfig = { debugmode true //enables logs in application }; // logger object factory var logger = function { var logger = {}; if applicationconfig debugmode === true { logger = { log function { var args = array prototype slice call arguments, 0 ; console log args ; }, info function { var args = array prototype slice call arguments, 0 ; console info args ; }, warn function { var args = array prototype slice call arguments, 0 ; console warn args ; }, error function { var args = array prototype slice call arguments, 0 ; console error args ; } }; } else { logger = { log function {}, info function {}, warn function {}, error function {} }; } return logger; }; // usage // for development and debugging var applicationconfig = { debugmode true }; var mylog = new logger ; // initializes logger mylog log 'test' ; // outputs 'test' to console //for production var applicationconfig = { debugmode false }; var mylog = new logger ; // initializes logger mylog log 'test' ; // does nothing importantnever override console log or any other native function overriding native objects is a bad practice in javascript, as it can lead to unexpected behavior and introduce defects that are very hard to debug optimization results the principles described in this guide were applied to several samsung tv applications, as listed in the following table

doclaunch time optimization this topic presents a case study of improving an application to reduce its launch time it describes the application launch process, techniques for reducing application loading time, and best practices for writing more efficient javascript applications that offer a good user experience ux attract more users users who have positive impressions of an application return to it and are more likely to recommend it to others if you monetize the application, this can result in greater profit application launch time is the total time from the moment when the user clicks the application icon until the application is ready to use improving the application launch time improves the user experience because application loading is the first experience the user gets of your application, a long loading time can leave them with a negative impression therefore, it is worthwhile to prioritize reducing application launch time user satisfaction drastically decreases as the application launch time increases, as shown in the following figure based on a user survey using this information, a target launch time of around 5-7 seconds satisfies most users application launch process the application launch process can be divided into 5 stages some stages are controlled by the system, but most stages are dependent on application implementation, providing opportunities for performance improvement this case study is based on an application running on a 2015 samsung smart tv video was captured while launching the application on the tv, enabling the duration of each application launch stage to be measured with an accuracy of one video frame noteif you want to test your application in a similar way, make sure that all tests are performed under the same circumstances, such as using the same device with the same network conditions, to reduce the effects of external factors the following figure illustrates the application launch stages, and the time spent at each stage for the case study application the following table describes each stage in detail stage action screen time description 1 application icon click 1 086s time between clicking the application icon to when the smart hub "apps" panel disappears 2 initial loading screen 4 979s time between loading the home page "index html" and calling the window onload method 3 black screen 0 837s time a transition screen is shown before calling the window onload method for samsung legacy platform applications only 4 splash image 0 570s time until the splash image appears the splash image is the first screen shown in the application after calling the window onload method it is usually shown during authentication or while content is loading 5 home page 0 348s time taken to render the home page, fill it with content, and enable user input table 1 application launch stages optimizing launch logic this section assumes that the case study application utilizes a framework the framework contains modules responsible for activities, such as sending ajax requests to the backend server, application authorization in the backend side, and modules responsible for the ui and logic the case study application loading process is illustrated in the following figure the application logic is dependent on the framework setup in stages 2 and 3, load and initialize the framework after the framework setup is complete, start authorization at the backend server with the application logic if authorization succeeds, send ajax requests to the backend server to fetch application data, such as a list of recommended movies to display on the application home page ajax requests are dependent on the authorization step, because they must contain an authorization token wait for the data needed to render the home page, and render it this model is not optimized because the entire framework must be loaded and initialized before the application can start the authorization and content loading processes a possible approach to speeding up the launch process is by rebuilding the application in the following way divide the framework setup into 2 phases in the first phase, load the modules responsible for application authorization in the second phase, initialize the rest of the framework once the first phase is loaded, perform authorization immediately it is only dependent on the xhr object created in stage 1 during web runtime setup multiple ajax requests are merged into 1 request to avoid unnecessary delays the ajax request is dependent on the authorization step for the authorization token when the framework is fully initialized, begin performing the basic home page setup without waiting for the ajax request response stage 3 is eliminated completely by migrating the application from samsung legacy platform to tizen padding time is needed to synchronize the application logic and ajax requests the application logic requires ajax request data to render the home page, but as the requests are asynchronous, implement mechanisms to coordinate the modules, such as events, callbacks, and promises resume the application logic after receiving the response from the server load other parts of application logic, such as required scripts and data, on demand in this way, they do not delay the launch process this flow is more optimized, as many tasks are performed in parallel initially, the application loads only the modules which are necessary for authorization and starts authorization immediately along with other operations, such as loading the rest of the framework, the ui, resources, and content any tasks not required for displaying the home page are postponed to start after the launch process consequently, application launch time is much shorter than before improving launch time the following table lists optimization strategies that can improve application launch time, and the application launch stages they affect optimization stage 1 2 3 4 5 migrating application to tizen + + enabling prelaunch + + + + minimizing home page code + + loading js files asynchronously + + sending ajax requests promptly + + parallelizing ajax requests

1 and 3 tizen is more efficient than samsung legacy platform migrating the application from samsung legacy platform to tizen can improve its performance significantly enabling prelaunch stages affected 1, 2, 4, and 5 tv web applications in tizen support prelaunching applications can load in the background when the samsung tv is switched on when the user launches the application, it loads more quickly because it has been prelaunched for more information, see prelaunching applications minimizing home page code stages affected 2 and 5 application launch time can be improved by loading and parsing less code at launch when the application launches, load only the html, js, and css code necessary to show the home page other code can be loaded on demand using a library, such as require js, to avoid building and parsing the dom before it is needed loading javascript files asynchronously stages affected 2 and 4 when loading external javascript files normally, the html parser stops while the javascript files are downloaded and executed to avoid the pause in html parsing during download, you can use the defer and async attributes <script src='js/main js' defer></script> <script src='js/scripts js' async></script> using the defer attribute downloads the javascript file in parallel while parsing html the javascript code executes only when all html parsing is complete scripts using the defer attribute are guaranteed to execute in the same order that they appear in the document using the async attribute downloads the javascript file in parallel while parsing html, but when the download completes, the html parser pauses to execute the script the defer and async attributes can be used only for scripts implemented with the script element and src attribute for more information, see the html <script> element handling ajax requests you can improve launch time by optimizing ajax request usage sending ajax requests promptly stages affected 2 and 4 most applications load their content from remote servers and utilize a framework that helps manage the requests however, loading and executing the framework code can take a lot of time to speed up application launch, send the ajax requests needed to display the home page as soon as possible you can send a simple xhr request at the beginning of the "index html" file, before loading the framework xhr requests are asynchronous and do not block any other threads cache the response in a global object, so the application framework can use the data immediately to display the home page without sending the request again parallelizing ajax requests send ajax requests in parallel if they are not dependent on responses from prior requests before each request is executed after receiving a response from the previous one sendrequest1 onsuccess sendrequest2 onsuccess sendrequest3 onsuccess sendrequest4 onsuccess sendrequest5 after the first request authorizes the application after receiving the response, the other requests are executed asynchronously sendrequest1 onsuccess sendrequest2 sendrequest3 sendrequest4 sendrequest5 concatenating ajax requests stages affected 2, 4, and 5 limit the number of ajax requests by merging several requests, if possible the fewer requests there are, the less time it takes to process all of them for example, consider an application that sends 3 requests to display the home page, such as for application authorization, a list of recommended movies, and a list of the latest movies verify whether it is possible to modify the requests and backend in such a way that the response for the authorization request contains the recommended and latest movies as well you can also use this strategy throughout the application to reduce the loading time of other scenes delaying platform and tizen api calls stages affected 2 and 4 many applications make early calls to tizen and platform apis for static information, such as the duid or model code because api initialization is "lazy" the api is initialized only when it is first needed , the first call to each api module takes time postpone api calls until the application is fully started and ready to use, if possible caching api output stages affected 2, 4, and 5 instead of querying the api each time, cache the static output from product and tizen apis in javascript variables consider the following scenarios the total duration of video content is constant during video playback you can retrieve it once and store it in a javascript variable instead of querying the api each time it is needed tv specification parameters, such as the duid or model code, never change you can retrieve the parameters using the api the first time the application is launched and save it in localstorage retrieving data from localstorage is quicker than querying the api using jquery 2 x or higher stages affected 2, 4, and 5 newer versions of jquery are smaller and faster you can also consider using a custom jquery build loading static resources locally stages affected 2 and 4 load static application resources directly from the local file system, by including all application source code, external libraries, and static ui elements, such as css and images, within the tizen package before <link rel='stylesheet' href='https //maxcdn bootstrapcdn com/bootstrap/3 3 5/css/bootstrap min css'> <link rel='stylesheet' href='https //example com/myapp/css/styles min css'> <script src='http //code jquery com/jquery-2 0 0 min js'></script> <script src='https //maxcdn bootstrapcdn com/bootstrap/3 3 5/js/bootstrap min

js'></script> this not only decreases loading time, but can also improve application security and eliminate some application errors caused by network issues minimizing and concatenating code stages affected 2 and 4 the application loads faster when it makes fewer requests to the file system if you do not want to use a lazy loading mechanism to load parts of the application on demand, concatenate and minimize your source code, especially javascript and css files before <!doctype html> <html lang='en'> <head> <meta name='viewport' content='width=1280, user-scalable=no'> <meta

bloghaving attended the online virtual adobe max conference for the past two years, it was amazing to be back in los angeles in person. unfortunately, this year's conference was limited to fewer attendees and offered fewer sessions. however, the magic was still there; amazing keynotes, highly informational sessions, great networking opportunities, an enormous expo floor, and the outrageous max bash party. my unique role at samsung allows me to utilize my graphic design skills to create social media assets, website graphics, animations, instructional videos, and podcasts. in addition, attending the conference allowed me to further my knowledge and gain new skills related to adobe's tools and services. the beautiful thing about adobe max is that if you could not attend in person, all the sessions are free online. check out the adobe max website for more information. you can also watch key moments of this year's conference on the adobe creative cloud youtube channel. highlights from adobe max 2022 attending the max sneaks keynote felt like i was transported into the future. it was truly magical to see adobe engineers demonstrating the fantastic new photo technology that can change a person's clothes, create original ai photos by simply typing keywords, and wrap artwork to 3d environments. engineers also showcased motion mix, which makes human animations from a single image. you can experience the future, with co-host comedian kevin hart, by watching the full max sneaks 2022 session on youtube. the expo floor was a great place to talk with companies that leverage adobe technology, network with fellow designers, and pick up a little conference swag. i especially appreciated learning about adobe's frame.io software, making it easy for teams to review video projects, comment, and track revisions. adobe max sessions as a designer, there were many sessions to choose from: software, marketing, social media, and more. below are several of my favorite sessions, including links to the online recorded videos. what's new in photoshop - s6305 joel baer director of product management, photoshop, adobe about the session * explore the latest features and updates in the photoshop ecosystem on both desktop and ipad, and discover how the photoshop team is innovating to help you work smarter and faster. join photoshop group product manager joel baer as he takes you through new creative features, workflow improvements, and performance enhancements. you'll be inspired, leaving with new ideas to spark your creativity and techniques to get more work done in less time. as joel shares the latest features in photoshop, you'll discover: improvements and updates to powerful photoshop features what's new in photoshop on desktop, ipad, and the web tips and techniques for newcomers, experts, and everyone in between my key takeaways i have been using adobe photoshop for my entire professional career. in fact, my first version of photoshop was version 2.0, back when photoshop did not have effects or even layers. however, over the past 25+ years, photoshop has become the leading image manipulation software by developing many unique tools that feel like magic. we probably all have heard someone say, "hey, that picture was photoshopped." attending joel bear's session on photoshop's latest features and improvements was a great way to learn quickly and be wowed by new tools and capabilities. i especially appreciated learning about the many neural filters to manipulate photos and create new imagery using artificial intelligence. here are a few of my key takeaways from joel's session on what's new in photoshop: the latest beta version of photoshop 2023 includes a new live gradient tool that allows you to manipulate non-destructive gradients on your workspace canvas. the updated object selection tool makes it far easier to select subjects like the sky, landscape, water, and other objects. to remove the subject from the scene, you can use content-aware to replace the selected area with the background. the new backdrop creator neural filter (beta) makes it incredibly easy to change the background of a photo. just type keyword prompts, and photoshop ai will magically create three new images based on your keywords that you can use to replace the background. the photo restoration neural filter (beta) can restore old scanned photos with damage like scratches. you can also enable the colorize filter to colorize black & white images using artificial intelligence automatically. watch the session on the adobe max site: what's new in photoshop premiere pro for social media - s6612 hallease narvaez executive producer / creative director, stumblewell about the session * social media has become a necessity for every creative regardless of focus. join digital storyteller and former adobe creative resident hallease narvaez to learn how to squeeze as much content as you can out of everything you capture by utilizing different features in premiere pro. you'll follow along as she takes a longer form piece of content and breaks it into standalone snippets for social. hallease will cover tools like auto reframe and remix for quick exports and music edits, teach you how to create captions for "sound off" videos, and share her tips to make everything pop using prebuilt graphics in the essential graphics panel. in this session, you'll learn how to use premiere pro to: maximize your content across social platforms auto-reframe sequences for different dimensions easily remix music to any length build closed captions create unique graphics quickly using motion graphics templates my key takeaways the latest reports from social media apps show that user engagement is far higher if you post a video rather than a still image. for this reason, i was very excited to attend hallease narvaez's session on using premiere pro to create social media assets. one of the challenges with making videos for social media is the different size requirements of each social media channel. hallease demonstrated using auto reframe, which utilizes motion tracking to maintain the focal point and convert your video into popular ratios such as 1:1, 4:3, and 9:16, all from the original 16:9 sequence. here are a few other key takeaways from hallease's session on premiere pro for social media: premiere pro's auto captions uses ai technology to create captions that are easy to edit and stylize. captions can be very useful for social media channels that do not allow audio. remix can take any song and edit it to a specific length. premiere pro's ai technology analyzes your music to find the optimum places to edit or loop sections of a song to fit your timeline. mogrts are motion graphic templates you can customize right in premiere pro. there are many templates to choose from that allow for very nice motion text overlays without the need to use adobe after effects. watch the session on the adobe max site: premiere pro for social media animation secrets: great motion transitions in after effects - s6615 nol honig designer, director, animator & educator, the drawing room about the session * making your animation stand out takes more than amazing design skills. knowing fundamental animation techniques in after effects and when to use them (and when not to) can transform a good animation into a great one. join award-winning director nol honig as he explains the underlying principles of effective transitions, and then shows you how to apply those techniques with examples. nol will cover the following - and more - in this informative session: the best way to accelerate and decelerate motion to catch eyeballs keyframe timing and spacing to effectively get your point across the one transition secret every motion designer should know - but not many do my key takeways of all the adobe programs i use, nothing gives me more joy than after effects. there is just something magical that happens when working with motion graphics. but unfortunately, i easily get into an after effects rut where i have used the same tools and techniques for years. luckily, nol's live demo showed me new approaches to animation. one such technique he uses is the graph editor to adjust motion timing. no longer will i use only the numeric values to adjust timing because, with the graph editor, i can change the timing of motion paths visually. here are a few other key takeaways from nol's session on animating in after effects: animating null objects linked to a camera is far easier than animating the camera properties. the best time to hide a cut is when motion is the fastest. adding motion blur to a moving element is a dated technique used only by beginners. watch the session on the adobe max site: animation secrets: great motion transitions in after effects say it with sound: maximizing audio workflows in premiere pro - s6606 nick harauz director of marketing at boris fx, boris fx about the session * while invisible, a proper audio mix is essential when delivering high-quality story content - the audio drives the viewer. join adobe certified instructor nick harauz as he shares proven techniques and tips for using the versatile tools and panels that make editing audio in premiere pro a breeze. in this session, you'll learn how to: identify and fix common audio problems such as plosives, background noise, and hums boost, repair, and unify dialogue in the essential sound panel use remix to recompose music tracks to fit any length automatically generate audio keyframes with auto ducking mix in other tracks, such as music and sound effects, to influence viewer perception enhance your audio with advanced tools and techniques in audition my key takeaways sound has become my new passion. as the host and producer of the samsung developers podcast and creating many tutorial videos on the samsung developer youtube channel, my appreciation for sound has grown exponentially over the past four years. with that comes experiencing the many challenges of working with sound. nick's session on maximizing audio workflows included many new techniques. my favorite is the sync feature when bringing audio from two different sources. premiere pro's sync feature uses ai to match the tracks and perfectly align within the timeline. here are a few other key takeaways from nick's session on maximizing audio workflows: dynamic link allows you to leverage the advanced audio editing tools in adobe audition within your premiere pro project. audio time units allow you to zoom into the timeline for more detailed editing. press the control + tilde keys to make your active premiere pro panel full-screen. adjust sound levels louder for social media. watch the session on the adobe max site: say it with sound: maximizing audio workflows in premiere pro these are just a few of the highlights i experienced during adobe max 2022. with so much more to discover, explore adobe max 2022 online. take your newfound knowledge and apply that expertise to the great things you create for samsung. community chalk wall display where attendees were inspired to leave their mark. * session descriptions are from the adobe max website resources for sellers at samsung galaxy store for more information on signing up and selling on galaxy store, look into the galaxy store documentation. for assistance with setting up and starting your sales campaigns, the samsung developer discussion forums are where you can get great insights from the galaxy store support team and other sellers. join us on twitter, facebook, linkedin, and youtube to continue the discussion.

Develop Samsung Browser
docweb payments integration guide overview to help standardize and streamline how payments are done on the web, the worldwide web consortium w3c has introduced a payment request api to provide an interface between a merchant web page and a mobile payment app, like samsung pay, to facilitate payment transactions samsung internet browser leverages the w3c payment request api to support samsung pay as a payment method for web purchases chrome also supports a samsung pay web payment method why integrate samsung pay into your website? samsung pay is accepted at more retail locations than any other mobile payment service available because of its unique ability to transact with newer nfc-supported payment terminals and legacy payment terminals it continues to enjoy the best user reviews among mobile payment apps now available for mobile website integration, samsung pay is secure, easy to set up, simple to use, and pre-installed on all new samsung galaxy-class smartphones when integrated with your website, samsung pay presents your users with a common checkout process that leverages samsung pay’s secure purchase authentication technology, eliminating manual entry or re-entry of card details and shipping destinations checkout is streamlined, conversions are maximized, and the exposure of sensitive data is kept to the absolute minimum simplifying the transaction process the benefits of the new process, certainly from an end-user perspective, is that the previous tedium ― request, authorization, payment, and result ― can now be handled in a single step for the web developer, it entails a single javascript api call for samsung pay users, there’s no change at all in the way a payment card is selected and authenticated after selecting the desired merchandise from the merchant’s web site, the user initiates checkout, selects samsung pay as the preferred payment method, authenticates with a fingerprint or pin, and voila ― payment complete that’s the user experience at its most basic when properly implemented, the api also supports editing the billing/shipping address in samsung pay and selecting a different enrolled card before approving the transaction with a fingerprint scan or entering a pin in terms of convenience, it’s a remote shopper’s dream ― no complicated, input-intensive forms to fill out, no fumbling for a plastic card to enter the account number, card expiration, and security code, and no worrying that someone other than the legitimate cardholder is attempting to make the payment meanwhile, samsung pay’s tokenized payload securely protects the transaction from intercept and replay attacks about this guide intended for web developers with a working knowledge of javascript and json, this guide takes you through the complete process of onboarding as a samsung pay merchant partner, creating/registering the w3c service for your domain, adding the w3c payment request object to your website, then testing and releasing your merchant website offering samsung pay as a payment method let's get started determining your gateway integration mode the api methods for integrating samsung pay with your website depend on the type of payment token your payment gateway pg handles — either gateway tokens or network tokens samsung pay supports requests for both types for instance, if stripe is your pg, you will want to request a gateway token from samsung pay on the other hand, if you’re using first data, you’ll want to request an encrypted network token bundle, for which you handle the token decryption yourself or work with the pg first data in this case to handle decrypting the token bundle the process begins when your merchant website makes a payment request and passes all required information to the browser, which then determines compatibility between the accepted payment methods for your website and the methods apps installed on the target device let’s take a brief look at how each integration mode — gateway token and network token — works with samsung pay gateway token mode although samsung pay doesn’t process the payment, your merchant website will still need to invoke the appropriate payment gateway apis to charge and process the token returned by your pg hence, when samsung pay returns a gateway token from stripe, for example, the recommended flow looks like this user selects samsung pay as the payment method at checkout in the merchant's website and the samsung pay app requests partner verification from the samsung pay online payment server encrypted payment information and the partner id are passed to the samsung-pg interface server samsung-pg interface server sends a transaction authorization request to the pg on behalf of the merchant; pg authenticates the partner id before generating a transaction reference id samsung-pg interface server returns the payment token to the pg i e , the gateway token it received from the samsung pay app in step 2 pg continues payment processing with the acquirer and payment network the result approved/declined is returned to the merchant website on the device for display to the user in this mode, samsung pay makes a call to your pg on your behalf and returns a chargeable gateway token network token mode under network token mode, the samsung pay api returns an encrypted network token bundle, which you can then either decrypt yourself or leverage the apis of your pg first data, for example to handle decryption and charge the token user selects samsung pay as the payment method at checkout in the merchant's website and the samsung pay app requests partner verification from the samsung pay online payment server encrypted payment information is passed from the samsung pay app to the pg through the merchant app via the pg sdk applying the merchant's private key, pg decrypts the payment information structure and processes the payment through the acquirer and payment network upon receiving authorization or rejection, pg notifies the merchant website through its pg sdk to simplify integration of network tokens, you can pass the encrypted payload directly to your pg and let it handle decryption in general, decrypting the payload yourself is more complex and involves private key management see your particular pg’s documentation for details once you determine which mode your pg supports, you're ready to register with the portal first, however, there are a number of prerequisites you'll need to satisfy prerequisites registering with the samsung pay developers portal and adapting the appropriate payment request apis for your website in accordance with the guidance contained herein will help to ensure a successful implementation to that end, the following requirements apply release contents minimum samsung pay app version 2 8 xx minimum samsung internet browser version 5 4 minimum chrome browser version 61 supported device models samsung galaxy-class smartphones running minimum version of the wallet app and browser supported payment gateways pgs view the most current list in the portal's payment gateway drop-down menu in service create/edit mode see step 5 under registering your domain for the w3c service registering with the portal through the samsung pay developers portal you can access valuable resources to help you manage the samsung pay features you incorporate into you partner app, including the ability to create multiple samsung pay service groups so you can use different services without the need to create multiple accounts invite co-workers to the portal to help you manage samsung pay features for your website register your website with samsung pay configure your samsung pay w3c service s to create a member account on the samsung pay developers portal open a browser like chrome, go to https //pay samsung com/developers, click sign up and confirm/acknowledge that you accept the samsung pay terms and conditions and understand the privacy policy, then do one of the following a if you already have a valid samsung account, click sign up and enter your samsung account id and password b if you do not have a samsung account, click create a samsung account to create one open the account activation email you receive and click the account activation link if you’re the first samsung pay member of your company to register, select the first option, click next, and complete a company and user profile if, on the other hand, you were given a samsung pay partner id by a co-worker, select the second option — my company is already registered — and enter your company’s partner id in the field provided, then click next after you receive notification by email that your membership is approved, typically within 2 business days, return to https //pay samsung com/developers, click sign in and enter your samsung account id and password for site access as a new member registering your domain for the w3c service your domain is the url associated with your website, whether in test or production the service type specifically associates w3c with your domain once you create the service, you will be prompted to configure the domain you want associated with it to create a new service go to my projects > service management and click create a new service select for test to define the service for initial integration with samsung pay, then click next select w3c mobile web payments as the service type and click next enter a service name and select “united states” as the service country select a payment gateway from the list of supported pgs if your payment gateway uses the network token mode, upload the certificate signing request csr you obtained from your pg supported formats are csr or pem contact your pg for details otherwise, key management is already established for pgs supporting samsung pay’s gateway token mode; hence, click connect with to create a new service connection with the pg and click ok enter the payment domain name s for your website in the service domain field and click add for example, if your domain is mywebstore com but the checkout page is hosted on the subdomain payments mywebstore com, you’ll need to enter payments mywebstore com as the service domain in the portal for each additional domain name, click add notewhen entering the domain name on the portal, do not include an https // prefix confirm your agreement with the terms and conditions, then click next adding w3c payment requests objects to your website in order to accept payments from samsung pay, your website must adhere to the w3c payment request api specification you can get started with the basics by completing the steps that follow and making the appropriate substitutions for your website step 1 feature detect prior making a w3c payment request, it’s wise to run a feature detect to ensure the browser in use supports the w3c payment request api if not, you should fall back to your traditional/normal checkout page example if window paymentrequest { // use payment request api } else { // fallback to traditional checkout window location href = ‘/checkout/traditional’; } step 2 create the paymentrequest constructor the first step is to create a paymentrequest object by calling the paymentrequest constructor, which has the following parameters methoddata – contains a list of payment methods that the website supports e g , visa, amex, samsung pay details – contains information about the shopping cart purchases e g , total, tax, fees, etc options – details pertaining to shipping address, user contact information, etc example var request = new paymentrequest methoddata, // required payment method data details, // required information about transaction options // optional parameter for things like shipping, etc ; step 3 add samsung pay to the methoddata parameter the methoddata parameter contains a list of payment methods supported by the merchant to support samsung pay, you’ll need to add it as a supported payment method notebasic-card is an optional supportedmethod for credit and debit cards saved in the browser, the card details of which are returned directly to the website from the browser before configuring this method, make sure your website and pg can handle generic payment information received from the browser and process with required pci compliance, if applicable see the [w3c basic card payment specification][7] for additional details be aware, however, that if you intend to support a branded samsung pay button, only samsung pay can be enabled as a payment method within the paymentrequest object; basic-card or any other payment method cannot be included if you already offer a generic payment request method, you can continue to do so — and include samsung pay as a payment method within that paymentrequest object from a user experience standpoint, the two distinct pathways look like this standard w3c implementation a standard w3c implementation adds samsung pay to your standard paymentrequest object as one of many supportedmethods available for user selection tapping checkout or its equivalent launches the standard browser payment sheet for user selection of the payment method and/or to add a debit/credit card to the list of options selecting samsung pay as the payment method and tapping pay launches the samsung pay payment sheet branded samsung pay implementation a branded implementation displays a "buy with samsung pay" button in place of your standard checkout button tapping the button will skip directly to the samsung pay payment sheet for authentication unless you specify paymentoptions if paymentoptions is not null, the browser payment sheet is launched see paymentoptions in step 7 for additional guidance first launching your website's checkout page is recommended for branded implementations this is because the samsung pay payment sheet only provides the user's billing address, which means your website will need to capture the user's preferred shipping address, where applicable for physical delivery of purchased goods if no shipping address and/or other options are needed, set the paymentoptions parameter to null as mentioned above, if you populate paymentoptions, the browser payment sheet is automatically launched keeping the foregoing implementations in mind, let's look at how to construct the methoddata argument for the network token mode and gateway token mode, respectively the fields in methoddata comprise supportedmethods – required; specifies https //spay samsung com/ i e , the samsung pay app and other methods suppored by your website data – values specific to the method; for samsung pay, these include version specifies the data structure being used by the merchant; should always be set to 1 until further notice required productid the service id obtained from the samsung pay partner portal required for partner verification; see step #8 under registering your domain for the w3c service merchantgatewayparameter this is the userid value registered with your pg required for gateway token mode in addition, userid should be set in the request parameter for mada token if a merchan request mada token, this field is mandatory as this filed should be included in the payload for mada token, there is a 15-character length limit paymentprotocol defaults to “protocol_3ds,” the only protocol currently supported by samsung pay optional allowedcardnetworks specifies the card brands/networks accepted by the merchant and supported by the pg required merchantname the name of the merchant to be displayed on the payment sheet; must be identical to the merchant name registered on the samsung pay partner portal required ordernumber unique value for merchant use as an external reference id optional isrecurring specifies transaction on subscription basis optional; default = false billingaddressrequired determines if a billing address must be filled-in by the user optional; default = false shown next are examples of the methoddata parameter for each of the supported token modes please note that samsung pay's w3c support for card brands is currently limited to mastercard, visa and american express discover is scheduled for support soon example – network token mode var methoddata = [ { supportedmethods ['https //spay samsung com'], data { 'version' '1', // always 1 until further notice 'productid' '2bc3e6da781e4e458b18bc', // service id from partner portal 'allowedcardnetworks' ['mastercard','visa'], 'merchantname' 'shop samsung demo ', // merchantname must be identical to merchant name on portal 'ordernumber' '1233123', } }] example – gateway token mode var methoddata = [ { supportedmethods ['https //spay samsung com'], data { 'version' '1', // always 1 until further notice 'productid' '7qr7h9ws1872bc3e6da781', // service id from partner portal 'merchantgatewayparameter' {"userid" "acct_ 17irf7f6ypzj7wor"}, 'allowedcardnetworks' ['mastercard','visa'], 'merchantname' 'shop samsung demo ', //merchantname must be identical with merchant name on portal 'ordernumber' '1233123', } }] step 4 fill out the transaction details parameter the details parameter contains information about the transaction there are two major components a total, which reflects the total amount and currency to be charged, and an optional set of displayitems that indicate how the final amount was calculated this parameter is not intended to be a line-item list, but is rather a summary of the order’s major components subtotal, discounts, tax, shipping costs, etc example var details = { displayitems [ { label "total of all items", amount { currency "usd", value "65 00" }, // us$65 00 }, { label "friends & family discount", amount { currency "usd", value "-10 00" }, // -us$10 00 pending true // the price is not yet determined } ], total { label "total", amount { currency "usd", value "55 00" }, // us$55 00 } } step 5 check eligibility to display samsung pay button if you do not support basic-card and you try to call show in step 6 when samsung pay or any other supportedmethod is not present on the device, the returned promise will reject with the following error domexception the payment method is not supported you can, however, check beforehand to see if the user has an available/supported method set up this is done with the canmakepayment method, which tells you whether the user has a payment method that can fulfill the current payment request example – canmakepayment const paymentrequest = new paymentrequest supportedpaymentmethods, transactiondetails, options ; // if canmakepayment isn’t available, default to assume the method is supported const canmakepaymentpromise = promise resolve true ; // feature detect canmakepayment if request canmakepayment { canmakepaymentpromise = paymentrequest canmakepayment ; } canmakepaymentpromise then result => { if !result { // the user does not have a supported payment method // todo redirect to traditional checkout flow return; } // todo the user has a payment - call show } catch err => { // todo either fall back to traditional checkout or call show } ; notebranded samsung pay buttons can be found on the [samsung pay developers][8] portal under the resources tab direct cdn links will be available soon step 6 call the show method to display the payment sheet the payment sheet can be activated by calling its show method this method invokes the browser’s native ui so the user can examine the details of the purchase, add or change the information, and submit it for payment a promise, indicated by its then method and callback function, resolves what will be returned when the user accepts or rejects the payment request example – show request show then function paymentresponse { // process paymentresponse here paymentresponse complete "success" ; } catch function err { console error "uh oh, something bad happened", err message ; } ; step 7 handle the paymentresponse once the user approves the payment request by verifying the payment option and shipping option if provided , the show method’s promise resolves, resulting in a paymentresponse object comprised of the following fields methodname string indicating the chose payment method e g , visa details dictionary containing information for methodname shippingaddress shipping address of the user, if requested shippingoption id of the selected shipping option, if requested payeremail email address of the payer, if requested payerphone telephone number of the payer, if requested payername name of the payer, if requested here, it’s important to remember that the response from the payment request api must be submitted by the merchant in accordance with the pg’s integration model and apis in all cases, the samsung pay response is encapsulated within the paymentresponse details parameter, which comprises the following fields paymentcredential – contains the payment credential information necessary for processing the transaction with the pg in network token mode, this field includes 3ds data in gateway token mode, it includes token information network token mode type use “s” version 1 0 0; standard for payment authentication aka mastercard securecode, verified by visa, and american express safekey data encrypted payload value gateway token mode reference token id reference status authorized or rejected/declined billingaddress – contains the billing address and related attributes for the cardholder, possibly including country [iso3166] alpha-2 code; canonical form is upper case for example, “us” addressline[n] most specific part of the address; can include a street name, a house number, apartment number, a rural delivery route, descriptive instructions, or a post office box number region top level administrative subdivision of the country; can be a state, a province, an oblast, or a prefecture city city/town portion of the address dependentlocality dependent locality or sub-locality within a city; fused for neighborhoods, boroughs, districts, or uk dependent localities postalcode postal code or zip code, also known as pin code in india sortingcode bank sorting code; for example, in the british and irish banking industries, the sort code is a six-digit number, is usually formatted as three pairs of numbers, for example 12-34-56, identifying both the bank and the branch where the account is held languagecode [bcp47] language tag for the address, in canonical form; used to determine the field separators and the order of fields when formatting the address for display organization organization, firm, company, or institution at this address recipient name of the recipient or contact person this member may, under certain circumstances, contain multiline information; for example, it might contain “care of” information phone telephone number of the recipient or contact person paymentinfo – contains the payment information, including card_last4digits last four digits of the card’s dpan cardbrand currently, either mastercard or visa ordernumber merchant’s unique external reference id supplied in the original request’s methoddata parameter if the user pays with a credit card using the basic-card method, then the details response returned directly to your website from the browser will contain cardholdername, cardnumber, expirymonth, expiryyear, cardsecuritycode, billingaddress example request show then paymentresponse => { var paymentdata = { // payment method string, e g “amex” method

method ‘post’, headers { ‘content-type’ ‘application/json’ }, body json stringify paymentdata } then res => { if res status === 200 { return res json ; } else { throw ‘payment error’; } } then res => { paymentresponse complete “success” ; }, err => { paymentresponse complete “fail” ; } ; } catch err => { console error “error, something went wrong”, err message ; } ; once payment information is received from samsung pay, the website should submit the payment information to the merchant’s pg for transaction processing the ui will show a spinner while the request takes place when a response is received, the website should call complete to close the ui the website is then free to show an order complete or order confirmation page for user feedback as previously mentioned, you can simplify integration of network tokens by passing the encrypted payload directly to your pg and letting it handle decryption in all cases, how you handle a submitted network token depends on the payment gateway refer to your particular pg’s documentation for details paymentoptions is an optional parameter in thepaymentrequest constructor depending on your particular requirements, you may want additional information, such as the user’s shipping address for physical goods purchased and contact details for guest users paymentoptions currently comprises the following requestpayername true if payer name is required; otherwise, false requestpayeremail true if payer email address is required; otherwise, false requestpayerphone true if payer telephone number is required; otherwise, false requestshipping true if shipping address is required; otherwise, false shippingtype available label options “shipping/pickup/delivery” for indicating to user; solely for display purposes example var options = { requestpayeremail false, requestpayername true, requestpayerphone false, requestshipping true, shippingtype "delivery" } noteif any of the elements listed above are set to true, the browser payment sheet is launched; otherwise, the samsung pay payment sheet is displayed putting it all together let’s assemble the various code blocks into a prototype to demonstrate the w3c payment request api in action function onbuyclicked { const samsung_pay = 'https //spay samsung com'; if !window paymentrequest { // paymentrequest api is not available - forwarding to legacy form based

provisioning payment cards through samsung wallet samsung pay sdk - sdk integrated into the partner app for direct communication with samsung wallet samsung wallet app - wallet app that the samsung pay sdk communicates with financial network - comprises the payment gateways, acquirers, card associations, and issuers that participate in transaction processing under agreement with the merchant the main classes comprising the samsung pay sdk include samsungpay – used by the partner app to get the samsung pay sdk information and the status of samsung wallet app on the device paymentmanager – provides payment/transaction functionality cardmanager – manages card list get, add, update functionality watchmanager – manages all functions related to samsung pay watch cardinfolistener – interface for requestcardinfo result from samsung wallet customsheettransactioninfolistener – interface for transaction success/failure callbacks from samsung wallet 3 1 3 uses cases in-app payment the most common in-app online payment use case take the following form merchant app presents user with the option of making payment with samsung wallet upon the user selecting the samsung pay option, the merchant app calls the apis included in the samsung pay sdk to initiate a transaction with samsung wallet app samsung wallet app responds with the tokenized payment information necessary to complete the transaction merchant app forwards this payment information to the designated payment gateway pg , either directly through the merchant's web server, or indirectly via the samsung-pg interface server for normal transaction processing app-to-app push provisioning the push provisioning use case ― adding payment cards to samsung wallet from the card issuer’s app ― typically takes this form the user logs into the issuer app the issuer app checks if samsung wallet is activated on the device and ready to use if it is in the ready status, the issuer app displays an add button for cards not currently registered/enrolled with the samsung wallet app if the add card option is selected, the issuer app calls an api to push the proper payload data to samsung wallet while the card is being provisioned, samsung wallet stays in background 3 1 4 setting up sdk development environment the importance of maintaining a good development environment cannot be overstated for integrating the samsung pay sdk with your partner app, the following prerequisites and recommendations help ensure a successful sdk implementation system requirements the samsung pay sdk is designed exclusively for samsung mobile devices supporting samsung pay and running android lollipop 5 1 android api level 22 or later versions of the android os the sdk’s in-app payments functionality requires android 6 0 m android api level 23 or later versions of the android os note as of sdk version 1 5, if the device runs android lollipop 5 1 android api level 22 or an earlier version, the getsamsungpaystatus api method returns a spay_not supported status code merchant apps still using samsung pay sdk 1 4 or earlier not recommended must check the android version running their app use the following snippet to determine the os version running on a device and whether or not to display the samsung pay button in your partner app import android os build; // in-app payment supported on android m or above // check android version of the device if build version sdk_int < build version_codes m { //hide samsung pay button} service registration to develop a samsung pay sdk service, merchants and issuers need to register for an account with samsung pay developers in order to create the appropriate service type for their applications here are some helpful links inside the portal become a member https //pay samsung com/developers/tour/memberguide create services https //pay samsung com/developers/tour/svcguide register apps https //pay samsung com/developers/tour/appsguide manage services and apps https //pay samsung com/developers/tour/svcnappsguide add samsung pay sdk to your project be sure to do the following before attempting to use the sdk if not already part of your environment, download and install an ide android studio is recommended download the samsung pay sdk the sdk package has the following directory structure folder contents docs javadoc – api reference documentation libs samsungpay jar sdk java archive file – contains the samsung pay apis to be used by your partner app samples sample apps configure your ide to integrate the samsung pay sdk with your partner app a add samsungpay jar to the libs folder of your android project b go to gradle scripts > build gradle and enter the following dependency dependencies { compile files 'libs/samsungpay jar' } c import the sdk package into your code import com samsung android sdk samsungpay v2; d proguard rules - if your app s have any issue with proguard, the following rules are recommended to enter in debug mode dontwarn

samsung android spay" /> <package android name="com samsung android samsungpay gear" /> </queries> 3 1 5 configuring api level api level attributes as of sdk version 1 4, enhanced version control management has been introduced to improve backward compatibility and handle api dependency from country and service type for example, if a partner integrates the latest sdk―for instance, api level 2 22―but continues to use apis based in level 1 4, the partner app remains compatible with samsung wallet apps supporting api level 1 4 without the necessity of upgrading the samsung pay app the chief characteristics and properties of the api level include every api starting from version 1 4 has an api level assigned based on the sdk version number in which it is introduced the sdk’s javadoc reference can be filtered by api level so you can determine the minimum api level you need to configure in the metadata section of your app’s androidmanifest file the earliest possible version is 1 4 this lets you use the api level defined in your androidmanifest without having to trigger an upgrade of the samsung wallet app on the user’s device implement the following usage in your androidmanifest <application <meta-data android name="spay_sdk_api_level" android value="2 22" /> // most recent sdk version is recommended to leverage the latest apis but it need to be set to 2 17 for russia </application> partner app verification in partner verification process samsung pay sdk verify your registered app, version in samsung pay portal and service it also determines device and app compatibility your app needs to verify the presence of the samsung wallet app on the device, its status, and whether or not its version is sufficient to support your implementation of the sdk 3 1

to check whether or not samsung pay is supported/activated/ready-to-use on a samsung device mst magnetic secure transmission tui trusted user interface 3 1 7 api common flow once setup is complete, you’re ready to add the sdk code within your partner app for calling the sdk’s apis and receiving callbacks when a partner app calls one of the sdk’s apis, the following interaction flow is processed to check whether the caller is authenticated and authorized before responding to the request the steps of the interaction are enumerated below step 1 the partner app calls a samsung pay sdk api the partner app initiates a call to the samsung pay sdk this could be to request in-app payment push provisioning status checks, etc step 2 sdk validates the preconditions the sdk performs initial checks before proceeding is samsung wallet installed on the device? is the integrity of the samsung pay system intact e g , no tampering or missing files ? step 3 sdk initiates communication with samsung wallet if preconditions are met, the sdk uses aidl android interface definition language to securely open a communication channel with the samsung wallet app step 4 samsung wallet app status validation samsung wallet app checks has the samsung pay setup been completed on the device? does the app require a mandatory update? is the samsung pay sdk api level used by the partner app compatible? step 5 partner app eligibility verification sdk triggers a backend verification with the samsung pay server to confirm the app’s package name, service id, and csr match what’s registered on the samsung pay developers portal the app is authorized to use the requested samsung pay functionality step 6 samsung wallet responds to sdk based on the above validations samsung wallet responds via aidl to the sdk it sends status codes, eligibility results, or additional prompts if needed e g , update required step 7 sdk triggers callback in the partner app the sdk invokes a callback function in the partner app this informs the app whether it can proceed with payment/provisioning an error or restriction has occurred step 8 partner app executes business logic based on sdk callback if successful initiate samsung pay payment ui or push provisioning complete transaction or card enrollment via the wallet app if unsuccessful inform the user offer fallback payment options provide guidance on enabling/updating samsung wallet 3 1 8 checking samsung pay status the first step in integrating the samsung pay sdk into your partner app is to create a samsung pay instance and check the status of samsung pay on the user's device this check determines whether the device supports samsung pay and if the samsung pay button should be shown as a payment or provisioning option the samsung pay button serves two key purposes for merchant apps, it enables users to select samsung pay for in-app payments for issuer apps, it allows users to add a card directly to samsung pay via push provisioning setting partnerinfo for verification before checking the status, the partner app must configure and pass a valid partnerinfo object to the samsungpay instance this is essential for verifying the calling app and enabling further sdk functionality the partnerinfo must include serviceid sid a unique identifier assigned by the samsung pay developer portal servicetype defines the type of service e g , merchant or issuer this value is also assigned during service registration samsung pay uses partnerinfo for validating the app’s identity and registration performing sdk version and api compatibility checks verifying allowlist/blocklist status note servicetype is required without it, you cannot call other samsung pay apis once partnerinfo is set correctly, you can proceed to call getsamsungpaystatus to check if samsung pay is available and ready for use on the device val serviceid = "partner_app_service_id" val bundle = bundle bundle putstring samsungpay partner_service_type, samsungpay servicetype inapp_payment tostring val partnerinfo = partnerinfo serviceid, bundle after setting partnerinfo, your partner app can now call getsamsungpaystatus this method of the samsungpay class must be called before using any other feature in the samsung pay sdk noteif you want to get the status of samsung pay watch, you have to use the watchmanager class instead of the samsungpay class fun getsamsungpaystatus callback statuslistener copy the result is delivered to statuslistener and provides the following events onsuccess ‒ called when the requested operation is successful it provides the status of the request, as well as extra bundle data related to the request onfail ‒ called when the request operation fails it returns the error code and extra bundle data related to the request the samsung pay status code returned is one of the following spay_not_supported - indicates samsung wallet is not supported on this device; typically returned if the device is incompatible with samsung pay or if the samsung wallet app is not installed spay_not_ready - indicates samsung wallet is not completely activated; usually returned if the user did not complete a mandatory update or if the user has not signed in with a valid samsung account in which case, the partner app can activate or update the samsung wallet app on the device according to the 'extra_error_reason' bundle keys below error_spay_setup_not_complete - tells the partner app to display a popup message asking if the user wishes to activate samsung pay if the user agrees, the partner app calls activatesamsungpay to activate the samsung wallet app error_spay_app_need_to_update - tells the partner app to display a popup message asking if the user wishes to update samsung pay if user agrees, the partner app calls gotoupdatepage to open the app update page error_partner_info_invalid - indicates that partner app information is invalid; typically, the partner app is using a sdk version that is not allowed, an invalid service type, or the wrong api level error_partner_sdk_api_level - tells the partner app it is using the wrong api level to resolve the error condition, the partner app must set a valid api level error_partner_service_type - tells the partner app that it did not set a service type, or that the service type it did set is invalid service type is set in partnerinfo spay_ready - indicates that samsung pay is activated and ready to use; typically returned after the user completes all mandatory updates and signs in extra bundle data can have the following values extra_country_code - for both onsuccess and onfail , this is the current device’s country code iso 3166-1 alpha-2 set by samsung pay if the partner app is not supported in this particular country, the partner app can decide not to display samsung pay button extra_error_reason - for onfailure , this is the reason for failure set by samsung pay when the returned status code is spay_ready, the partner app can safely display the samsung pay button for user selection as a payment option, push provisioning, and so on the following sample code shows how to use the getsamsungpaystatus api method val serviceid = "partner_app_service_id" val bundle = bundle bundle putstring samsungpay partner_service_type, samsungpay servicetype inapp_payment tostring val partnerinfo = partnerinfo serviceid, bundle val samsungpay = samsungpay context, partnerinfo /* * method to get the samsung pay status on the device * partner issuers, merchants applications must call

"checksamsungpaystatus onfail $errorcode" } } 3 1 9 activating the samsung wallet app the samsungpay class provides the following api method to activate the samsung wallet app on a device fun activatesamsungpay activatesamsungpay is called to activate the samsung wallet app on the same device on which the partner app is running first, however, the partner app must check the samsung pay status with a getsamsungpaystatus call see section 4 2 above if the status is spay_not_ready and extra_error_reason is error_spay_setup_not_complete, the partner app needs to display an appropriate message to user, then call activatesamsungpay to launch the samsung wallet app so the user can sign in here’s an example of how to code this val serviceid = "partner_app_service_id" val bundle = bundle bundle putstring samsungpay partner_service_type, spaysdk servicetype inapp_payment tostring val partnerinfo = partnerinfo serviceid, bundle val samsungpay = samsungpay context, partnerinfo samsungpay activatesamsungpay 3 1 10 updating the samsung wallet app the samsungpay class provides the following api method to update the samsung wallet app on the device fun gotoupdatepage gotoupdatepage is called to update samsung wallet app on the same device on which the partner app is running as with all api calls, the partner app must first check the samsung pay status with getsamsungpaystatus if this returns spay_not_ready and extra_error_reason is error_spay_app_need_to_update, then the partner app needs to display an appropriate message to the user and call gotoupdatepage , which launches the samsung pay update page the following code sample reflects how to update samsung pay val serviceid = "partner_app_service_id" val bundle = bundle bundle putstring samsungpay partner_service_type, spaysdk servicetype inapp_payment tostring val partnerinfo = partnerinfo serviceid, bundle val samsungpay = samsungpay context, partnerinfo samsungpay gotoupdatepage 3 1 11 in-app online the main classes and interfaces involved here are samsungpay– class for a merchant app to get samsung pay sdk information and the status of samsung pay on the device paymentmanager – class to provide payment/transaction functionality cardinfolistener – interface for requestcardinfo result callbacks from samsung wallet customsheettransactioninfolistener – interface for transaction success/failure callbacks from samsung wallet; payment information is provided with a success callback and must be used by the merchant app for processing the payment the flow pictured next captures the essential online payment api process between merchant apps integrated with the samsung pay sdk and samsung wallet and the merchant’s payment gateway pg 3 1 12 api flow for in-app payments the api flow for samsung pay in-app payments involves a series of operations that ensure secure, seamless, and verified payment processing between the merchant app, samsung wallet, and the payment gateway pg these steps are illustrated in the flow diagram above and described below check the ready status of samsung pay use samsungpay getsamsungpaystatus to verify whether samsung pay is installed and supported on the device samsung pay is activated and ready for transactions the user has completed mandatory updates and account setup start the payment manager to establish the service binding and verify the merchant app establish a binding between your app and the samsung wallet app validate that the merchant app is authorized and registered prepare the sdk to handle payment operations get payment card information and the payment amount, including updates this step also includes displaying eligible cards to the user allowing the user to select a card for the transaction collecting or updating the payment amount get/update the user’s billing and shipping addresses, including an updated payment amount if shipping charges will be incurred if required by the transaction retrieve or update the user’s billing and shipping address recalculate and update the total payment amount e g , shipping cost impact authenticate the user trigger authentication via trusted user interface tui , using biometrics or other secure methods supported by samsung wallet submit payment information to pg this ensures the user has authorized the transaction send the tokenized payment data received from samsung pay to your designated payment gateway pg for transaction processing this can be done via a direct merchant server-to-pg connection, or samsung pg interface server if applicable verify transaction success or failure receive confirmation of transaction success or failure from the payment gateway communicate the result back to the user and update your app's ui and backend accordingly 3 1 13 token modes network vs gateway to complete the payment, the merchant’s designated payment gateway pg handles one of two types of tokens gateway tokens indirect or network tokens direct the samsung pay sdk supports both types the essential difference between the two types is who decrypts the token information network tokens require that the merchant app handles decryption of the token bundle or work with the pg to handle decryption, whereas gateway token decryption is handled by the pg via the samsung-pg interface server network token mode direct user selects samsung pay as the payment method at checkout in the merchant app and the samsung pay app requests partner verification from the samsung pay online payment server encrypted payment information is passed from the samsung pay app to the pg through the merchant app via the pg sdk applying the merchant's private key, pg decrypts the payment information structure and processes the payment through the acquirer and payment network upon receiving authorization or rejection, pg notifies the merchant app through its pg sdk gateway token mode indirect user selects samsung pay as the payment method at checkout in the merchant app and the samsung pay app requests partner verification from the samsung pay online payment server encrypted payment information and the partner id are passed to the samsung-pg interface server samsung-pg interface server sends a transaction authorization request to the pg on behalf of the merchant; pg authenticates the partner id before generating a transaction reference id reference id is passed to merchant app via sdk callback merchant app then passes the reference id to the pg for payment process execution samsung-pg interface server returns the payment token to the pg i e , gateway token it received from samsung pay app in step 2 pg continues payment processing with the acquirer and payment network the result approved/declined is returned to the merchant app on the device for display to the user check with your pg to determine its specific requirements for payment processing regardless of the pg model employed, direct or indirect, the goal is to offer samsung pay as a secure payment method within your merchant app the most common use case involves the following general steps to make a purchase, the user selects to “buy” or got to checkout after adding items to a shopping cart now in checkout, the user selects a payment option; for example, either the merchant’s “standard” method or samsung pay upon selecting samsung pay, the user is presented with a payment sheet that allows for card selection and shipping address confirmation with the option to add/modify information for this order, whereupon the user makes payment card selection from the list of enrolled cards chooses to change or add the delivery address enters required address information in the form presented and saves it authenticates the payment method, amount, and delivery with a biometric verification fingerprint, iris… or pin 3 1 14 checking registered/enrolled card information before displaying the samsung pay button, a partner app can query card brand information for the user’s currently enrolled payment cards in samsung wallet to determine if payment is supported with the enrolled card for example, if a merchant app accepts one card brand exclusively but the user has not registered any cards matching this brand in samsung wallet, the merchant app needs to determine whether or not to display the samsung pay button for this purchase checkout to query the card brand, use the requestcardinfo api method of the paymentmanager class the requestfilter is optional bundle data reserved for future use the merchant app does not need to set a value for it now however, before calling this method, cardinfolistener must be registered so its listener can provide the following events onresult - called when the samsung pay sdk returns card information from samsung wallet; returns information about enrolled cards or is empty if no card is registered onfailure - called when the query fails; for example, if sdk service in the samsung wallet app ends abnormally the following snippet shows how to retrieve the list of supported card brands from samsung pay val serviceid = "partner_app_service_id" val bundle = bundle bundle putstring samsungpay partner_service_type, spaysdk servicetype inapp_payment tostring val partnerinfo = partnerinfo serviceid, bundle val paymentmanager = paymentmanager context, partnerinfo paymentmanager requestcardinfo bundle , cardinfolistener // get card brand list //cardinfolistener is for listening requestcardinfo callback events val cardinfolistener cardinfolistener = object cardinfolistener { // this callback is received when the card information is received successfully override fun onresult cardresponse list<cardinfo> { var visacount = 0 var mccount = 0 var amexcount = 0 var dscount = 0 var brandstrings = "card info " var brand spaysdk brand? for i in cardresponse indices { brand = cardresponse[i] brand when brand { spaysdk brand americanexpress -> amexcount++ spaysdk brand mastercard -> mccount++ spaysdk brand visa -> visacount++ spaysdk brand discover -> dscount++ else -> { /* other card brands */ } } } brandstrings += " vi = $visacount, mc = $mccount, ax = $amexcount, ds = $dscount" log d tag, "cardinfolistener onresult $brandstrings" toast maketext context, "cardinfolistener onresult" + brandstrings, toast length_long show } /* * this callback is received when the card information cannot be retrieved * for example, when sdk service in the samsung wallet app dies abnormally */ override fun onfailure errorcode int, errordata bundle { //called when an error occurs during in-app cryptogram generation toast maketext context, "cardinfolistener onfailure " + errorcode, toast length_long show } } 3 1 15 creating a transaction request upon successful initialization of the samsungpay class, the merchant app needs to create a transaction request with payment information note as of sdk v2 0 00, the normal payment sheet is deprecated all merchant apps must now use the custom payment sheet, which offers more dynamic controls for tailoring the ui look and feel with additional customer order and payment data merchant app developers choosing to temporarily continue offering the normal sheet will need to configure their android manifest to reflect the pre-2 0 00 version of the sdk used to implement their app’s existing normal sheet, although this is not recommended in all cases, merchant app developers should update their apps with the latest version of the sdk as soon as possible to avoid timing out using an earlier version of the sdk when responding to samsung pay callbacks using the custom payment sheet to initiate a payment transaction with samsung pay’s custom payment sheet, your merchant app must populate the following mandatory fields in customsheetpaymentinfo merchant name - as it will appear in samsung pay’s payment sheet, as well as the user's card account statement amount - the constituent transaction properties currency, item price, shipping price, tax, total price which together determine the total amount the user is agreeing to pay the merchant cautionnot populating the mandatory fields throws an illegalargumentexception optionally, the following fields can be added to the payment information merchant id- can be used for the merchant’s own designated purpose at its discretion unless the merchant uses an indirect pg like stripe or braintree if an indirect pg is used, this field must be set to the merchant’s payment gateway id fetched from the samsung pay developers portal merchant id is mandatory if a merchant requests with a mada token, this field should be included in the payload order number - usually created by the merchant app via interaction with a pg this number is required for refunds and chargebacks in the case of visa cards, the value is mandatory the allowed characters are [a-z][a-z][0-9,-] and the length of the value can be up to 36 characters address - the user’s billing and/or shipping address see applying an addresscontrol for details allowed card brands - specifies card brands accepted by the merchant if no brand is specified, all brands are accepted by default if at least one brand is specified, all other card brands not specified are set to "card not supported’ on the payment sheet here’s the 'customsheetpaymentinfo' structure class customsheetpaymentinfo parcelable { private val version string? = null private val merchantid string? = null private val merchantname string? = null private val ordernumber string? = null private val

} your merchant app sends this customsheetpaymentinfo to samsung wallet via the applicable samsung pay sdk api methods upon successful user authentication in direct mode, samsung wallet returns the above "payment info" structure and a result string the result string is forwarded to the pg by your merchant app to complete the transaction it will vary based on the pg you’re using note if you want to add any other information for any card brand, you can add them in the extrapaymentinfo bundle the following example demonstrates how to populate customsheet in the customsheetpaymentinfo class see sample merchant app using custom payment sheet below for example usage of each customsheet control /* * make user's transaction details * the merchant app should send customsheetpaymentinfo to samsung

requesting payment with a custom payment sheet the startinapppaywithcustomsheet method of the paymentmanager class is applied to request payment using a custom payment sheet in samsung wallet the two methods are defined as follows startinapppaywithcustomsheet - initiates the payment request with a custom payment sheet the payment sheet persists for 5 minutes after the api is called if the time limit expires, the transaction fails updatesheet - must be called to update current payment sheet as of api level 1 5, a merchant app can update the custom sheet with a custom error message refer to updating sheet with custom error message when you call the startinapppaywithcustomsheet method, a custom payment sheet is displayed on the merchant app screen from it, the user can select a registered card for payment and change the billing and shipping addresses, as necessary the result is delivered to customsheettransactioninfolistener, which provides the following events onsuccess - called when samsung pay confirms payment it provides the customsheetpaymentinfo object and the paymentcredential json string customsheetpaymentinfo is used for the current transaction it contains amount, shippingaddress, merchantid, merchantname, ordernumber api methods exclusively available in the onsuccess callback comprise getpaymentcardlast4dpan – returns the last 4 digits of the user's digitized

use the updatesheet method to update the shipping fee or any other relevant information in the payment sheet set the errorcode to determine if the address provided by samsung wallet app is invalid, out of delivery, or does not exist for example, when the merchant does not support the product delivery to the designated location billing address from samsung wallet is not valid for tax recalculation for all such cases, the merchant app should call updatesheet with one of the following error codes error_shipping_address_invalid error_shipping_address_unable_to_ship error_shipping_address_not_exist error_billing_address_invalid error_billing_address_not_exist the sample code included below under applying the address control demonstrates how to use the updatesheet method for 'addresscontrol' in the payment sheet 3 1 17 payment credential sample the paymentcredential is the resulting output of the startinapppaywithcustomsheet method the structure varies

extracted “3ds” part only consult your pg documentation for specific guidance when using indirect model e g stripe in indirect gateway token mode, paymentcredential is the pg’s token reference id and its status here’s a sample of the json output { "reference" "tok_18rje5e6szui23f2mefakep7", "status" "authorized" } for stripe, your merchant app should be able to pass this token object directly to charge or another appropriate payment processing api provided by the pg 3 1 18 push provisioning the following diagram illustrates the flows of the app-to-app apis for payment card push provisioning the main classes involved are samsung pay – for fetching samsung wallet app status and wallet information on the device paymentmanager – for push provisioning and invoking favorite cards payment functionalities cardmanager – for payment card management watchmanager – for all functions related to samsung pay watch 3 1 19 requesting registered card list in the samsung pay the getallcards method of the cardmanager class is used to request a list of all cards currently registered/enrolled in samsung wallet on the same device running the issuer’s app to succeed, the issuer app must pass valid partnerinfo to 'cardmanager' for caller verification 'cardfilter' narrows the card list returned by samsung wallet to the issuername specified please be noted that getsamsungpaystatus must be called before getallcards getallcards could not return a cards list when getsamsungpaystatus responds with a code other than spay_ready noteto get the cards list of samsung pay watch, you have to use the watchmanager class instead of the cardmanager class as of api level sdk version 1 4, cardfilter retrieves this information from the samsung pay developers portal certain issuers may need to register multiple issuer name s with the portal, depending on their app and/or the requirements of their token service provider tsp the getallcards parameter cardfilter matches the issuer name s specified with those registered in the portal only complete matches are returned this method is typically called when your partner app wants to check the card status it does not need to be called every time the partner app resumes therefore, you should create the card list with the 'oncreate ' method, rather than the 'onresume ' method the result of a getallcards call is delivered to getcardlistener, which provides the following events onsuccess - called when the operation succeeds; provides the list of all filtered cards and their status card information includes cardid, cardstatus, and extra cardinfo data onfail - called when the operation fails here’s an example of how to use the 'getallcards ' api method in your issuer app val cardfilter = bundle // since api level 1 4, cardfilter param is ignored partner does not need to use it here // it is retrieved from the samsung pay developers portal cardfilter putstring cardmanager extra_issuer_name, issuername cardmanager getallcards null, object getcardlistener{ override fun onsuccess cards mutablelist<card>? { // getting card status is success if cards == null || cards isempty { log e tag, "no card is found" return } else { // perform operation with card data for s in cards { log d tag, "cardid " + s cardid + "cardstatus " + s cardstatus // get extra card data if s cardinfo != null { val cardid = s cardid // since api level 2 13, id from card network val last4fpan = s cardinfo getstring cardmanager extra_last4_fpan val last4dpan = s cardinfo getstring cardmanager extra_last4_dpan val cardtype = s cardinfo getstring cardmanager extra_card_type val cardissuername = s cardinfo getstring cardmanager extra_issuer_name log d tag, "last4fpan $last4fpan last4dpan $last4dpan cardid $cardid" } } } } override fun onfail errorcode int, errordata bundle? { // getting card status is failed } } 3 1 20 getting wallet information the samsungpay class provides the getwalletinfo api method, which is called to request wallet information from the samsung wallet app prior to calling the addcard api, when you want to avoid duplicate provisioning your issuer app uses this information to uniquely identify the user and the samsung wallet app on a particular device wallet device management id, device id, and wallet user id note to get wallet information of samsung pay watch, you have to use the watchmanager class instead of the cardmanager class fun getwalletinfo list<string> keys, statuslistener callback the following example demonstrates how to use it // set the serviceid assigned by the samsung pay developers portal during service creation val serviceid = "sampleserviceid" val bundle = bundle bundle putstring samsungpay extra_issuer_name, "issuer name" bundle putstring samsungpay partner_service_type, servicetype app2app tostring val pinfo = partnerinfo serviceid, bundle val samsungpay = samsungpay context, pinfo // add bundle keys to get wallet information from samsung pay // this information can be delivered to the partner server for an eligibility check val keys = arraylist<string> keys add samsungpay wallet_user_id keys add samsungpay device_id samsungpay getwalletinfo keys, object statuslistener{ override fun onsuccess status int, walletdata bundle { // log d tag, "dowalletinfo onsuccess callback is called" ; // for visa, deviceid can be set to "clientdeviceid" as defined by visa val deviceid = walletdata getstring samsungpay device_id // for visa, walletuserid can be set to "clientwalletaccountid" as defined by visa val walletuserid = walletdata getstring samsungpay wallet_user_id } override fun onfail errorcode int, errordata bundle? { log e tag, "onfail callback is called, errorcode " + errorcode ; // check the extra error codes in the errordata bundle for all the reasons in // samsungpay extra_error_reason, when provided } } 3 1 21 adding a card to samsung pay your issuer app calls the 'addcard ' api method of cardmanager to add a card to samsung wallet by providing the required card details, your app can make it convenient and easy for users to add their bank-issued debit/credit cards to samsung wallet directly from your app without additional steps, like switching between apps note if you want to add a card to samsung pay watch, you have to use the 'watchmanager' class instead of the cardmanager class for most issuers, getwalletinfo suffices for requesting current wallet information the response from samsung wallet tells the issuer app whether or not the user’s card has already been added to samsung wallet or is ineligible for provisioning it is therefore recommended that you call getwalletinfo before displaying the add to samsung pay button if the card is eligible, display the “add” button and, if the user taps it, call addcard important remember to obtain the governing issuer implementation guide s and specifications from the respective card network and implement each network’s required handling in your partner app and server the 'addcard ' result is delivered to addcardlistener, which provides the following events onsuccess - called when the operation succeeds; provides information and status regarding the added card onfail - called when the operation fails; returns the error code and extra bundle data such as extra_error_reason or extra_request_id if provided onprogress - called to indicate the current progress of the 'addcard ' operation; can be used to show a progress bar to the user in the issuer app this callback is supported for tsm solution issuers in china and spain here’s an example of how to use the addcard api method in your issuer app val cardtype = card card_type_credit val tokenizationprovider string = addcardinfo provider_abcd // samsung pay does not provide detailed payload information; generate the provisioning payload in // accordance with your card network specifications val testpayload = "thisistestpayloadcardinfo1234567890" //bin bank identification number can be set to issuerid it is mandatory for some card network val issuerid = "123456" val carddetail = bundle carddetail putstring extra_provision_payload, testpayload carddetail putstring extra_issuer_id, issuerid val addcardinfo = addcardinfo cardtype, tokenizationprovider, carddetail cardmanager addcard addcardinfo, object addcardlistener { override fun onsuccess status int, card card? { log d tag, "onsuccess callback is called" ; } override fun onfail errorcode int, errordata bundle? { log d tag, "onfail callback is called" ; // check some extra error codes in the errordata bundle // such as samsungpay extra_error_reason or samsungpay extra_request_id if provided } override fun onprogress currentcount int, totalcount int, bundledata bundle? { log d tag,"onprogress callback is called " + currentcount + " / " + totalcount ; } } 3 1 22 adding a co-badge card to samsung pay co-badge payment cards combine two payment brands/networks to add a co-badge card through push provisioning, you must provide two different card network details one for the primary card network and another for the secondary card network issuer app calls the addcobadgecard api method of cardmanager to add a co-badge card to samsung pay in most cases, calling getwalletinfo will suffice to request current wallet information the response from samsung pay indicates whether the user's co-badge card has already been added to samsung pay or is ineligible for provisioning therefore, it is advisable to call getwalletinfo before displaying the add to samsung pay button if the co-badge card is eligible, display the "add" button and, upon user tapping, call addcobadgecard important please remember to refer to the relevant issuer implementation guide s and specifications provided by each card network and ensure that your partner app and server adhere to their specific requirements the addcobadgecard result is delivered to addcardlistener, which provides the following events onsuccess - called when the operation succeeds; provides information and status regarding the added card onfail - called when the operation fails; returns the error code and extra bundle data such as extra_error_reason or extra_request_id if provided onprogress - called to indicate the current progress of the 'addcard ' operation; can be used to show a progress bar to the user in the issuer app this callback is supported for tsm

applications sample apps, use cases, and ux strategies are included here to aid you in understanding the sdk and implementing it in your application sample source code and apks can be downloaded from download section sample merchant app included with the samsung pay sdk to demonstrate its features, the sample merchant app shows you how to implement the payment sheet’s dynamic controls to leverage additional customer order and payment data and/or create a more custom ui look and feel the following payment sheet controls are available addresscontrol plaintextcontrol amountboxcontrol spinnercontrol controls are applied to suit a particular purpose or need for example, displaying a promotion notice in the payment sheet using the plaintextcontrol applying an addresscontrol this control is used to display the billing or shipping address on the payment sheet based on samsung pay’s my info user profile or addresses provided by your merchant app during the transaction request when creating the control, controlld and sheetitemtype are needed to distinguish the billing address from the shipping address otherwise, your merchant app sets the following properties address title – displays a merchant-defined title on the payment sheet if empty, the default title such as “billing address” is displayed address – provides various methods to retrieve address details the merchant app can retrieve the phone number using the 'getphonenumber' method of 'customsheetpaymentinfo' address starting from api level 1 5, the addressee’s email address has also been added retrieve the email address using 'getemail' you can also set a display option for the shipping address with 'setdisplayoption' for more information, see the samsung pay sdk-api reference javadoc and the sample code included with the samsung pay sdk sheetupdatedlistener – used to capture the response from the samsung wallet app; merchant app must deliver to the samsung wallet app an amountboxcontrol to display payment information on a custom payment sheet when the onresult callback is called, the updatesheet method must also be called to update the current payment sheet errorcode – used for containing error codes directly related to the address the workflows for billingaddresscontrol the workflow for shippingaddresscontrol the following sample code demonstrates use of addresscontrol on the payment sheet fun makebillingaddresscontrol addresscontrol { val billingaddresscontrol = if !iszipcodeonly { // for billing address addresscontrol billing_address_id, sheetitemtype billing_address billingaddresscontrol addresstitle = "billing address" } else { /* * for billing address with zip code only * since api level 2 19, sheetitemtype zip_only_address * for us country only */ addresscontrol billing_address_id, sheetitemtype zip_only_address billingaddresscontrol addresstitle = "zip code" } //this callback is received when controls are updated billingaddresscontrol

display_option_address displayoption_val += addressconstants display_option_phone_number displayoption_val += addressconstants display_option_email shippingaddresscontrol displayoption = displayoption_val return shippingaddresscontrol } here’s how these controls display on a custom payment sheet billing address control zip code billing address control shipping address control applying a plaintextcontrol this control is used for displaying a title with two lines of text or a single line of text without a title on the payment sheet when allocating this control, a controlid is needed the merchant app sets both the title, as applicable, and the text diagrammed below is the flow between your merchant app and samsung pay plaintextcontrol flow the merchant app code invoking this class would look something like the following fun makeplaintextcontrol plaintextcontrol { val plaintextcontrol = plaintextcontrol "exampleplaintextcontrolid" plaintextcontrol settext "plain text [example]", "this is example of plaintextcontrol" return plaintextcontrol } and this is how it displays on the custom payment sheet applying an amountboxcontrol amountboxcontrol is used for displaying purchase amount information on the payment sheet it requires a controlid and a currencycode, and consists of item s and amounttotal, defined as follows and diagrammed on the next page item – consists of id, title, price, and extraprice if there is an extraprice in amountboxcontrol, its text is displayed on the payment sheet even though there is an actual numerical price value if there is no extraprice, then currencycode with the price value is displayed amounttotal – consists of price and displayoption the displayoption allows predefined strings only your merchant app can set the text to “estimated amount”, “amount pending”, “pending”, “free”, and so forth the ui format for the string is different for each option note the setamounttotal api may accept strings that are not predefined as an argument, but it generates an invalid parameter condition or returns an error code in such cases for details, see the javadoc samsung pay sdk-api reference, available in the documentation folder of your downloaded sdk package here’s a coding example to demonstrate the use of amountboxcontrol in a payment sheet fun makeamountcontrol amountboxcontrol { val amountboxcontrol = amountboxcontrol amount_control_id, "usd" amountboxcontrol additem product_item_id, "item", 1000 0, "" amountboxcontrol additem product_tax_id, "tax", 50 0, "" amountboxcontrol additem product_shipping_id, "shipping", 10 0, "" amountboxcontrol setamounttotal 1060 0, amountconstants format_total_price_only amountboxcontrol additem 3, product_fuel_id, "fuel", 0 0, "pending" return amountboxcontrol } the merchant app can also add new items using the 'additem' method of 'amountcontrolbox' during callback important your merchant app needs to call the updatevalue item_id method of amountboxcontrol to update each amount item then call customsheet updatecontrol to make the changes take effect in customsheet eventually, paymentmanager updatesheet 'customsheet' must be called to let samsung pay know that no further action is pending in the merchant app when the custom sheet is updated, the merchant can add new items to amountboxcontrol for example, if the user selects a specific card in the payment sheet which the merchant offers, a discount item can be added via the updatesheet // example for adding new item while updating values val amount = sheet getsheetcontroll "id_amount" amount updatevalue "itemid", 900 0 amount updatevalue "taxid", 50 0 amount updatevalue "shippingid", 10 0 amount updatevalue "fuelid", 0 0 // add “discount” item amount additem 4, "discountid", "discount", -60 0, "" amount setamounttotal 1000 0, amountconstants format_total_price_only sheet updatecontrol amount // call updatesheet with amountboxcontrol; mandatory try { paymentmanager updatesheet sheet } catch e illegalstateexception { e printstacktrace } catch e nullpointerexception { e printstacktrace } applying the spinnercontrol this control is used for displaying spinner options on a payment sheet when creating the control, controlid, title, and sheetitemtype are needed to distinguish between the types of spinner to be displayed your merchant app sets the following properties with spinnercontrol title – the merchant-defined spinner title to appear the payment sheet sheetitemtype – provides various types of spinner a shipping_method_spinner and an installment_spinner are the two types of spinner available as of api level 1 6 note shipping_method_spinner can be used when the shipping address comes from the samsung wallet app; i e , when the customsheetpaymentinfo addressinpaymentsheet option is set to need_billing_and_shipping or need_ shipping_spay when the shipping address is provided by the merchant app send_shipping or need_billing_ send_shipping , it is not changeable in the payment sheet the shipping fee if applied must be pre-calculated on the merchant app side here’s an example of constructing a spinnercontrol within your merchant app // construct spinnercontrol for shipping method val spinnercontrol = spinnercontrol shippingmethod_spinner_id, "shipping method ", sheetitemtype shipping_method_spinner // let the user can select one shipping method option on the
