Develop Samsung Internet
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

blogin a previous blog article, we learned how we could utilize samsung wallet's rp sdk in order to verify a user's identity from an android application. in this tutorial, we learn how to verify a user's identity directly from a website using samsung wallet and its web2app api in a spring boot web server. prerequisites the process described has the following prerequisites: a valid us driver's license or state id for the user whose identity is to be verified the samsung galaxy device used needs to be registered for the us region and have mdl support complete the samsung wallet partner onboarding process create a wallet card template with the relying party type in the samsung wallet partners portal implementing the verify with wallet functionality in your website the verify with wallet (vww) process utilizing the web2app method consists of two distinct parts. the "verify with samsung wallet" button. this button contains the vww link with the rp card data tokenized as the cdata. the user can click this vww link to initiate the verification process. the partner server containing the /key and /auth endpoints. the partner server processes the requests sent from the samsung wallet application and handles the complete vww process. frontend configuration in order to initiate the verify with wallet process, we need to implement a "verify with samsung wallet" button in a webpage. implementing the button is a very simple process similar to creating a traditional "add to wallet" button. we can make use of the data transmit link approach and create a button that contains the vww link: https://a.swallet.link/vww/v1/{cardid}#clip?cdata={cdata} replace {cardid} with the id of your own card. meanwhile, the cdata value needs to be generated in real time. this is done using a process similar to generating cdata for atw operation, only with the payload contained being different according to the specification for the relying party card type. check out the sample code for the complete process of cdata generation and using it in the button. backend configuration once the button implementation is complete, you need to configure your server to handle the exchange of information between your server and samsung wallet application. the vww process requires the partner to define 2 api endpoints: /rp/v1.0/{cardid}/{refid}/key: establishes a secure session and prepares the request data for the process. /rp/v1.0/{cardid}/{refid}/auth: processes encrypted authentication data and mdl data received from the wallet application. the workflow for the information exchange is as follows: once the vww button is clicked, the samsung wallet application opens. samsung wallet checks if the device has a driver's license already enrolled in the device. if an mdl already exists on the device, the samsung wallet application calls the /key endpoint to establish a session. after establishing session with the partner server and retrieving the mdoc request, the samsung wallet application prompts the user to confirm if they wish to share their information with the partner. after the user confirms that they wish to proceed, the application finally sends the requested information to the /auth api to complete the vww process. define the /key endpoint when the user clicks the "verify with samsung wallet" button, the samsung wallet application first checks if a driver's license is enrolled. if a license is found, the application generates "device engagement bytes" in accordance with the iso-18013-5 specification. these bytes are then transmitted to the server's /key api endpoint to establish a verification session. the post request body is json with a single field called data. this field value is the jwt containing encrypted device engagement bytes. {"data": "………"} in the /key api endpoint, accept the post request sent to the path /{cardid}/{refid}/key extract the data field from the body as the jwt and decrypt it to receive the device engagement bytes. establish a session using the device engagement bytes. create the mdoc request data and send it back to the samsung wallet application as response to the post request. the complete process is shown below: @postmapping("{cardid}/{refid}/key") fun receivekey( @pathvariable cardid: string, @pathvariable refid: string, @requestbody body: string ): responseentity<string> { val cdata = jsonparser.parsestring(body).asjsonobject.get("data").tostring() val base64engagementbytes = jwtgen.decryptbase64engagement(cdata) val mdoc18013 = createmdoc10813(base64engagementbytes) val cdataresponse = "{\"data\": \"${jwtgen.generaterequestjwt(mdoc18013)}\"}" return responseentity.ok().contenttype(mediatype.application_json).body(cdataresponse) } decrypt the device engagement bytes from the request body the data field value received in the /key api contains the required device engagement bytes encoded in the jwt format. simply decrypt the jwt in order to retrieve the device engagement bytes. here the decryptbase64engagement() function is defined as follows: fun decryptbase64engagement(data: string): bytearray { val signedjwt: signedjwt = signedjwt.parse(data) val payload = signedjwt.payload val jwe = jweobject.parse(payload.tostring()) val partnerprivatekey = keyutil.readprivatekey(partner_private_key) val decrypter = rsadecrypter(partnerprivatekey) jwe.decrypt(decrypter) val base64engagement = jwe.payload.tojsonobject().get("data").tostring() val base64engagementbytes = base64.geturldecoder().decode(base64engagement) return base64engagementbytes } simply perform the jwt decryption operation using your private key to get the decrypted jwe payload in the json format. in the json-formatted payload, the data field contains the device engagement bytes encoded in the base64url string format. decode the string using a base64url decoder and you get the final device engagement bytes. create a shared session using device engagement bytes the createmdoc10813(base64engagementbytes) function creates a shared session between the /key api and /auth api using a companion object. having a shared session between the two endpoints is mandatory in order to decrypt the information provided by the samsung wallet application later on. inside the companion object, we also need to generate an elliptic curve keypair in order to establish the encrypted session. the companion object is defined as shown below: companion object{ val keypair = keyutil.generateeckeypair() var mdoc18013: mdoc18013? = null fun createmdoc10813(base64engagementbytes: bytearray): mdoc18013 { if (mdoc18013 == null ) { mdoc18013 = mdoc18013(keypair, base64engagementbytes ) return mdoc18013!! } else{ return mdoc18013!! } } fun getmdoc10813(): mdoc18013 { return mdoc18013!! } } the elliptic curve keypair is generated using a simple keypairgenerator class instance. fun generateeckeypair(): keypair { val keypairgenerator = keypairgenerator.getinstance("ec") val ecgenparameterspec = ecgenparameterspec("secp256r1") keypairgenerator.initialize(ecgenparameterspec) return keypairgenerator.generatekeypair() } prepare the mdoc request data preparing the mdoc request data is the most crucial part of the vww operation. the request data defines the data that needs to be retrieved from mdl. the generaterequestjwt() function can be divided into several parts: define and encode the request data payload. encrypt the device request. create session establishment data using the encrypted device request bytes. create a signed jwt. below, we go through these steps one at a time. define the request data payload and encode it to a cbor byte array // define requested data fields val requestdata = """ { "doctype": "org.iso.18013.5.1.mdl", "namespaces": { "org.iso.18013.5.1": { "family_name": true, "age_in_years": true, "issue_date": true, "expiry_date": true, "document_number": false, "issuing_authority": false }, "org.iso.18013.5.1.aamva": { "dhs_compliance": false } } } """.trimindent() // cbor encoding process with tagging val firstencoded = cborobject.fromjsonstring(requestdata).encodetobytes() val thirdencoded = cborobject.fromobjectandtag(firstencoded, 24).encodetobytes() val itemrequestbyteslist = listof(thirdencoded) // create mdoc items requests array val docrequestsarray = cborobject.newarray() itemrequestbyteslist.foreach { val docrequest = cborobject.newmap() docrequest.set("itemsrequest", cborobject.decodefrombytes(it)) docrequestsarray.add(docrequest) } // create device request using docrequestarray val devicerequest = cborobject.newmap() devicerequest.set("version", cborobject.fromobject("1.0")) devicerequest.set("docrequests", docrequestsarray) encrypt the device request val encrypteddevicerequestbytes = mdoc18013.encryptdevicerequest(devicerequest.encodetobytes()) create session establishment data using the encrypted device request bytes val establishment = cborobject.newmap() establishment.set("ereaderkey", cborobject.fromobjectandtag(mdoc18013.getereaderkey(),24)) establishment.set("data", cborobject.fromobject(encrypteddevicerequestbytes)) val establishmentstring = base64.geturlencoder().encodetostring(establishment.encodetobytes()) create a signed jwt using the establishmentstring as the jwe payload val jweobj = jweobject(jweheader.builder(jwealgorithm.rsa_oaep_256, encryptionmethod.a128gcm).build(), payload(establishmentstring)) val encryptor = rsaencrypter(samsungpublickey as rsapublickey) jweobj.encrypt(encryptor) val jwsheader = jwsheader.builder(jwsalgorithm.rs256) .contenttype("auth") .customparam("partnerid", "412255212345678910") .customparam("certificateid", "a123") .customparam("ver", "3") .customparam("utc", system.currenttimemillis()) .build() val jwsobj = jwsobject(jwsheader, payload(jweobj.serialize())) val rsajwk = rsakey.builder(partnerpublickey as rsapublickey).privatekey(partnerprivatekey).build() val jwssigner = rsassasigner(rsajwk) jwsobj.sign(jwssigner) return jwsobj.serialize() now, we can send this jwt back as the response from the /key api. if everything is done properly, the samsung wallet application should receive the verification request along with the list of requested fields. after processing and verifying the request, the samsung wallet application needs to prompt the user to verify their identity. once the user verifies their identity using the application, it sends the requested information back to the /auth api endpoint. next, let's define the /auth api endpoint to retrieve the requested information. define the /auth api endpoint similar to the previously defined /key api endpoint, the /auth api endpoint also receives a single json payload with a single field called data, which contains the requested information in a jwt encoded format. {"data": "………"} decrypt the jwt payload from the request body we can extract the data field and decrypt the jwt following the same process used in the /key api. @postmapping("{cardid}/{refid}/auth") fun receiveauth( @pathvariable cardid: string, @pathvariable refid: string, @requestbody body: string ): httpstatus { val responsedata = jsonparser.parsestring(body).asjsonobject.get("data").tostring() val signedjwt: signedjwt = signedjwt.parse(responsedata) val payload = signedjwt.payload val jwe = jweobject.parse(payload.tostring()) val partnerprivatekey = jwtgen.partnerprivatekey val decrypter = rsadecrypter(partnerprivatekey) jwe.decrypt(decrypter) // process and decrypt the data until the requested information is retrieved return httpstatus.ok } after the decryption operation, we get another json object in the decrypted jwe payload. in this json payload, the data field contains the encoded data of the information we requested. to decode and decrypt this data: decode the extracted data field value using base64url decoder. this gives us the encrypted mdoc response in a cbor byte array. decode the cbor object from the byte array and get the mdoc data from the data field. decrypt the mdoc data using the mdoc18013.decryptmdocresponse() function to retrieve the plain response in the json format. warningthe mdoc18013 instance used for this step must be the same instance used in the /key api. otherwise, the decryption operation fails. val mdoc18013 = getmdoc10813() val cbordata = jwe.payload.tojsonobject().get("data").tostring() val decodeddata = base64.geturldecoder().decode(cbordata) val mdocresponse = cborobject.decodefrombytes(decodeddata) val mdocdata = mdocresponse.get("data") val decryptmdocresponsebytes = mdoc18013.decryptmdocresponse(mdocdata.getbytestring()) val plainresponse = cborobject.decodefrombytes(decryptmdocresponsebytes).tojsonstring() after these steps, we finally have the mdoc response in a plain json format. { "status": 0, "version": "1.0", "documents": [ { "doctype": "org.iso.18013.5.1.mdl", "devicesigned": {}, "issuersigned": { "issuerauth": ["......."], "namespaces": { "org.iso.18013.5.1": [

blogwhat do successful apps and developers have in common? over the next five weeks we’ll be featuring profiles of successful devs who started with a kernel of an idea, a great team and some help from samsung, and went on to deliver apps are now being enjoyed by thousands. hear directly from these devs about their projects, their processes and the things that made the difference between success and failure in our five part series. to kick-off our ‘devs doing it right’ interview series, we spoke with catalin butnariu, the general manager of carbon incubator, a games incubator/accelerator with a mission to grow the games industry in eastern europe by helping local independent developers craft beautiful games and build viable businesses. you’re general manager at carbon incubator, whose mission is to grow the gaming industry in eastern europe by helping developers craft their games. tell us more about it. well, independent developers in eastern europe have always had a hard time finding funding, marketing, advice and support. there was a discussion between a small group of people from different companies in the area. we wanted to know how we could launch a business that would develop the local indie gaming industry in romania. and, about six months later, carbon incubator was born. our mandate is to help developers get their games off the ground by providing services such as mentoring, customer support, publishing support, quality assurance, trade show support, physical working space, equipment, and more. we even offer development grants. can you talk a little bit about some of the things you have learned about opening up new markets for games studios and growing an industry from the ground up? you have to be prepared to do a lot when you’re essentially starting a new industry. personally, i do a little bit of everything – from finding investors and building the overall game plan to setting up new partnerships, working with teams and getting involved in the daily projects. we’re very much an incubator, and as such, have to take on many different tasks. we have three full-time employees and a network of collaborators and mentors with industry experience in a wide range of specializations. we’re small, but we’re nimble and we like that. we don’t want to get too big just yet. what are some of the games you have created? last year, we picked up five games in different genres, and plan to find five more in 2017. our first game was link twin. i believe it was the first title ever to launch with the games for samsung program (replaced by galaxy store games). another exciting project is marble land, a physics-based vr puzzle game that offers a fun, immersive experience for people with gearvr headsets. we recently released a second game through the games for samsung program, called high on cake. we also have two other mobile titles and a pc game. what was the biggest technical hurdle you had to overcome when building link twin? one key hurdle we had to clear when building link twin was figuring out our tech stack. this needs to be done right at the beginning. your chosen tech stack can either create or alleviate a lot of problems. determining your tech stack should ultimately come down to what type of tools and features you want in each part of the game. it’s a decision that you should put a lot of time and thought into. it was a hurdle in our case because we had initially chosen some tools which seemed right at the time, but eventually created a bunch of issues and had to be changed. what do you see as the biggest opportunity for indie game developers in the future? there’s no magic formula for indie game developers to find success. it always helps to keep your eye on market trends, but the truth is you need to have an interest and expertise in whatever you end up doing. today, vr and ar are hot topics, but don’t limit yourself to these trends if you don’t have a real interest in them. my advice is to develop games for a platform you’re passionate about and that fits your particular skill set. as a developer, what new technologies/ trends are you most excited about? i’m a big fan of esports and see a lot of room for growth in the industry. but for developers, in general, i believe ar actually has more potential than vr. while it’s obviously great, vr can almost be too immersive because it requires an incredibly focused, dedicated experience. on the other hand, ar expands or adds things to a user’s current context, so it’s easier to use by more people. it offers enhanced interaction without the need for total immersion. do you have any words of wisdom for other indie game developers? share your ideas. i’m constantly running into developers who don’t want to showcase their games at events because they’re scared someone is going to steal their idea. but anyone can have a good idea. what it’s really about is execution— how is your game to play? is it actually fun? if you’re an indie game developer, you should be looking to get your ideas out in world as soon as possible. you need that feedback or validation, or otherwise you may waste months or years fine-tuning a game that might not even be that fun to play. what are your thoughts on the games for samsung program? it has been an awesome experience. when link twin was accepted into the program in july 2016, we were all very excited. being selected by samsung was validation for our business— we could use it as our company’s calling card. the samsung team was also extremely supportive every step of the way. the biggest benefit was in creating visibility for the game after its release. this is gold for any developer. when you’re just starting out, one of the biggest challenges is getting reach for a game, but thanks to samsung’s promotion we were able to attract those initial users, and link twin ended up reaching 200,000 downloads on the galaxy app store. this was an excellent result for us. finally, a question we’re asking all of our ‘devs doing it right’: what features do all great/successful apps have in common? they have to ultimately appeal to your target audience. this may sound overly simplistic, but the successful games are the ones that are fun to play. i’ve seen a ton of projects from a lot of different indie studios, and while some may have good monetization schemes and/or excellent graphics, their games just aren’t fun to play. at the end of the day, you need to develop something that people enjoy.

cards through samsung pay samsung pay sdk sdk integrated into the partner app for direct communication with samsung pay samsung pay app pay app with which the samsung pay sdk communicates financial network comprises the payment gateways, acquirers, card associations, and issuers that participate in transaction processing under agreement with the merchant most common use case for in-app payment the merchant app allows the user to make payments with samsung pay upon user selection of the samsung pay option, the merchant app calls the apis included in the samsung pay sdk to initiate a transaction with the samsung pay app the samsung pay app responds with the tokenized payment information necessary to complete the transaction the 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 standard transaction processing for more detailed information,

will the user get some notification when they renew next time? no the service provider must relay this information to the buyers before the changes are made, because samsung checkout does not send price change notifications to buyers who subscribe to subscription products tv#price change#notification q14 does the samsung checkout charge users based on local currency, or based on the credit card that is used? for example, can you pay with us credit card in columbia? will the card be charged in local currency, or in usd? you will be charged in local currency tv#local currency q15 what are "customid" and "ordercustomid"? "customid" and "ordercustomid" have the same value "customid" also uses the same value as "ordercustomid" when calling buyitem if you have a unique id, use it if not, use the samsung account uid tv#customeid#ordercustomid q16 how is the provider's user account data matched with samsung checkout's transaction list? this is done using "ordercustomid" if the provider has a user account, they can put the value in the "ordercustomid" parameter when calling the buyitem api this value is mapped to the transaction list's "order custom id" column tv#ordercustomid#transaction list product type this section includes information related to product types that can be purchased using the samsung checkout service limited period q17 in the response data of the "invoice/list" api, are `period`, `appliedtime`, `limitendtime`, and `remaintime` always present for `invoicedetails` objects that have an `itemtype` of limited period? yes tv#limited period#invoice details#item type q18 in the api spec document for the response data of "invoice/list" api, `limitendtime` is listed as "limited period product end time, in 14-digit utc time" does this mean that the field is not mandatory, that it should either exist and be a 14-digit string, or that it should not exist? no, limitendtime must exist when a limited period product is applied tv#limited period#limited end time q19 from the response data of "invoice/list" api, what is the expected value of the `limitendtime` field when a purchase hasn’t been applied yet? it appears that for limited period item purchases that have not been applied `itemtype` is "3" , the `limitendtime` field is set to "" correct limitendtime is calculated based on the date and time when the purchase is applied tv#limited period#limited end time#item type subscription q20 in the response data of the "invoice/list" api, is `subscriptioninfo` ever present for `invoicedetails` objects that do not have an `itemtype` of subscription? subscriptioninfo is shown only when itemtype is subscription tv#subscription info#invoice details#item type q21 does an invoiceid ever change, or is it static? if a new purchase is made, does it always generate a new invoiceid? the invoiceid is generated when the buyer subscribes to a product for regular payment however, subscriptionid is generated only when the buyer subscribes a product for the first time samsung checkout uses the first invoiceid as the subscriptionid and it is never updated tv#invoiceid#subscriptionid q22 does subscription end date `subsendtime` get updated as soon as a user has been successfully billed for the upcoming period of the subscription? no, the subscription end date subsendtime describes the expiry time of this subscription not nextpaymenttime tv#subscription end time q23 how is a month defined in subscriptions? calendar month or 30/31 days? calendar month the next month's payment is made on the same day of the month as the day the consumer first applied for the subscription for example, if the consumer applied for a subscription on november 14th, the next payment is made on december 14th for months that don't have a day corresponding to the settlement date such as the 31st , payment is made at the end of the month tv#calendar month#subscription q24 would the canceling of a subscription/closing of the account automatically trigger a refund at samsung checkout? no even if the consumer withdraws their samsung account or cancels a subscription to the regular payment, this does not refund any payments already charged on the next settlement date, the subscription status is changed from 'active' to 'expired', and regular payment is stopped tv#subscription#samsung account#cancel#refund

<meta-data android:name="spay_sdk_api_level" android:value="2.xx" /> <!-- latest version is recommended] --> implement functionality now that the samsung pay sdk integration is complete, let us use this sdk to implement the complete functionality of the samsung pay sdk in your android application. here we will go through the complete flow of initiating a payment using the samsung pay sdk. check samsung pay availability initiating a payment starts by checking if samsung wallet is available for payment or not. initialize the samsung pay service with your partner credentials, then verify if samsung pay is supported. if available, display the samsung pay button in your app. val serviceid = "partner_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) samsungpay.getsamsungpaystatus(object : statuslistener { override fun onsuccess(status: int, bundle: bundle) { when (status) { samsungpay.spay_not_supported -> samsungpaybutton.setvisibility(view.invisible) samsungpay.spay_not_ready -> { samsungpaybutton.setvisibility(view.invisible) val errorreason = bundle.getint(samsungpay.extra_error_reason) if (errorreason == samsungpay.error_setup_not_completed) samsungpay.activatesamsungpay() else if (errorreason == samsungpay.error_spay_app_need_to_update) samsungpay.gotoupdatepage() } samsungpay.spay_ready -> samsungpaybutton.setvisibility(view.visible) } } override fun onfail(errorcode: int, bundle: bundle) { samsungpaybutton.setvisibility(view.invisible) log.d(tag, "checksamsungpaystatus onfail() : $errorcode") } }) set up payment details and request the payment after the availability check is completed, you need to set up the payment details such as merchant information, transaction information, order number, and so on, before requesting the payment. the following code snippets show how to accomplish this. make customsheet create a simple custom payment sheet with amounts and items for the transaction. this sheet will be displayed during the payment process. you can customize the sheet according to your requirements. private fun makeupcustomsheet(): customsheet { val amountboxcontrol = amountboxcontrol(amount_control_id, mbinding.currency.selecteditem.tostring()) amountboxcontrol.additem( product_item_id, mcontext.getstring(r.string.amount_control_name_item), mdiscountedproductamount, "" ) amountboxcontrol.additem(

.setaddressinpaymentsheet(customsheetpaymentinfo.addressinpaymentsheet.do_not_show) .setallowedcardbrands(brandlist) .setcardholdernameenabled(mbinding.cardbrandcontrol.displaycardholdername.ischecked) .setcustomsheet(makeupcustomsheet()) .build() return customsheetpaymentinfo } request the payment initiate the samsung pay payment process with transaction details and handle payment callbacks. mpaymentmanager.startinapppaywithcustomsheet( maketransactiondetailswithsheet(), object : customsheettransactioninfolistener{ override fun oncardinfoupdated( selectedcardinfo: cardinfo?, sheet: customsheet? ) { // update your controls if needed based on business logic for card information update. // updatesheet() call is mandatory pass the updated customsheet as parameter. try { paymentmanager.updatesheet(customsheet) } catch (e: java.lang.illegalstateexception) { e.printstacktrace() } catch (e: java.lang.nullpointerexception) { e.printstacktrace() } } override fun onsuccess( customsheetpaymentinfo: customsheetpaymentinfo?, paymentcredential: string?, extrapaymentdata: bundle? ) { // triggered upon successful payment, providing customsheetpaymentinfo and paymentcredential. // for example, you can send the payment credential to your server for further processing with pg. or you could send it directly to the pg as per business need. sendpaymentdatatoserver(paymentcredential) } override fun onfailure(errcode: int, errordata: bundle?) { // fired when the transaction fails, offering error codes and details. log.d(tag, "onfailure() : $errcode") showerrordialog(errcode, errordata) } }) testing and release test and validate to ensure a seamless and reliable integration of samsung pay, thorough testing is essential. this process validates transaction performance and guarantees a positive user experience for making a robust business impact. testing goes beyond error detection; it aims to comprehensively assess the quality and functionality of your samsung pay integration. release after successful testing, the next step is to secure release version approval from
