Samples

Implement a billing system for in-app purchases in your application, by using Samsung Checkout through the DPI service APIs and the Billing API.

Prerequisites

To implement in-app purchases:

  1. Before you start implementing Samsung Checkout in your application, start registering your application at the Samsung Apps TV Seller Office. You do not need to complete the registration with your source code at this point. To be able to use the DPI portal, you need to proceed to the second step of the App Registration Page and set the "Billing" field to "Use" and the "Samsung Checkout on TV" field to "Yes". You can save the registration at this point and return to it later when your source code is complete. For more information, see the Samsung Checkout DPI Portal Guide.

  2. To use the DPI, Billing, ProductInfo, and Sso APIs, the application has to request permission by adding the following privileges to the "config.xml" file:

    <tizen:privilege name="http://developer.samsung.com/privilege/sso.partner"/>
<tizen:privilege name="http://developer.samsung.com/privilege/productinfo"/>
<tizen:privilege name="http://developer.samsung.com/privilege/billing"/>

  3. To use the methods of the Billing, ProductInfo, and Sso APIs, include the “webapis.js” library in the “index.html” file:

    <script type='text/javascript' language='javascript' src='$WEBAPIS/webapis/webapis.js'></script>

  4. Initialize the required variables:

    1. Retrieve the User ID:
      var UniqueCustomId = webapis.sso.getLoginUid(); // Unique ID for this user
    1. Retrieve the country code:
    var countryCode = webapis.productinfo.getSystemConfig(webapis.productinfo.ProductInfoConfigKey.CONFIG_KEY_SERVICE_COUNTRY);
    1. Retrieve the server type:
    var strTVServer = webapis.productinfo.getSmartTVServerType();
    1. Set the DPI URL and service environment depending on the server type:
    strUrlDPI = "https://checkoutapi.samsungcheckout.com/openapi";
strServer = "PRD";
strSecurityKey = "********";

DPI Service APIs

You can use the APIs provided by the DPI service to manage products and sales. The DPI service APIs communicate data in JSON format, using the POST method.

Generating Check Values

The check value is used by the DPI service to verify Purchase List and Products List API requests. It is a Base64 hash generated by applying the HMAC SHA256 algorithm on a concatenated string of parameters using the DPI security key.

The application can also use the check value to verify that API response data from the DPI server is legitimate. To ensure the data integrity of requests and responses in real time, generate and verify the check value for API requests and responses during runtime.

To generate the check value, the following 2 items are used as parameters:

  • Concatenation of the required parameters

    For example, “12345”+”123”+”US”+”2”+”1” is concatenated to “12345123US21”.

    The required parameters vary depending on the API.
  • DPI security key

    The DPI security key is issued at the DPI portal.

You can use any open library to generate the HMAC SHA256 hash. The following example uses the CryptoJS library:

var appId = "1234567890"; // Your application ID
var UniqueCustomID = "yourUniqueID"; // Retrieved during initialization
var countryCode = "US"; // Retrieved during initialization
var itemType = "2"; // Request value for "invoice/list" API
var pageNumber = 1; // Request value for "invoice/list" API

var detailObj = new Object();
detailObj.AppID = appId; // Your application ID
detailObj.CustomID = UniqueCustomID; // Same value as OrderCustomID parameter for buyItem()
detailObj.CountryCode = countryCode; // TV country code
detailObj.ItemType = itemType; // "2": all items
detailObj.PageNumber = pageNumber;
var reqParams = detailObj.AppID + detailObj.CustomID + detailObj.CountryCode + detailObj.ItemType + detailObj.PageNumber;
/* Required Parameters
   [invoice/list] Request : appId + UniqueCustomID + countryCode + itemType + pageNumber
   [cont/list] Request : appId + countryCode
   Response : CPStatus, CPResult, TotalCount, ItemID(Seq)
*/

var hash = CryptoJS.HmacSHA256(reqParams , securityKey);
var checkValue = CryptoJS.enc.Base64.stringify(hash);

Requesting User Purchases

The Purchase List API ("invoice/list") requests the list of purchased items for a specific user, usually the currently logged-in user. The API response identifies whether purchased products have been applied or have been refunded.

To call the Purchase List API:

// Generate CheckValue
var reqParams = detailObj.AppID + detailObj.CustomID + detailObj.CountryCode + detailObj.ItemType + detailObj.PageNumber;
/* Required Parameters
   [invoice/list] Request : appId + UniqueCustomID + countryCode + itemType + pageNumber
   [CheckValue] required
*/

var hash = CryptoJS.HmacSHA256(reqParams, securityKey);
var checkValue = CryptoJS.enc.Base64.stringify(hash);

detailObj.CheckValue = checkValue;
var paymentDetails = JSON.stringify(detailObj);

// Call API
$.ajax({
  url: urlDPI + "/invoice/list",
  type: "POST",
  contentType: "application/json;charset=UTF-8",
  dataType: "JSON",
  data: paymentDetails,
  timeout:10000,
  success: function(res) {
    // For implementation details, see the Samsung Checkout sample application
    console.log("success : " + JSON.stringify(res));
  },
  error: function(jqXHR, ajaxOptions, thrownError, request, error) {
  console.log("[Error] thrownError:"+thrownError+";error:"+error+";[Message]:"+jqXHR.responseText);
  },
  complete:function() {
    console.log("complete");
  },
  failure:function() {
    console.log("failure");
  }
});

*/
var detailObj = new Object();
detailObj.AppID = appId; // Your application ID
detailObj.InvoiceID = unCanceledItems[key].InvoiceID; // Issued by "invoice/list"
detailObj.CustomID = UniqueCustomID; // Same value as OrderCustomID parameter for buyItem()
detailObj.CountryCode = countryCode; // TV country code

var paymentDetails = JSON.stringify(detailObj);

// Call API
$.ajax({
  url: strUrlDPI + "/invoice/verify",
  type: "POST",

    Table 6. Verify Purchase API response parameters

Applying Products

The Apply Product API ("invoice/apply") supports product management to help guarantee secure sales of your products. Normally, the DPI service is notified that the purchased product has been successfully applied. The Apply Product API is used in situations where purchase result delivery to the application encounters issues and is not successful. For example, if the network connection is interrupted, the application can fail to receive the “payment complete” message, even though the payment was completed. In this situation, the product is not applied to the application. You can check for unapplied products using the "AppliedStatus" parameter of the Purchase List API response and apply the product at that time.

For subscription products, the product is considered applied at the time of purchase and the "AppliedStatus" is set to "true" by default. Consequently, it is not necessary to check whether a subscription product purchase corresponding to the requested "InvoiceID" was successful.

To call the Apply Product API:

/* Required Parameters
   [invoice/apply] Request
*/

var detailObj = new Object();
detailObj.AppID = appId; // Your application ID
detailObj.InvoiceID = unCanceledItems[key].InvoiceID; // Issued by "invoice/list"
detailObj.CustomID = UniqueCustomID; // Same value as OrderCustomID parameter for buyItem()
detailObj.CountryCode = countryCode; // TV country code

var paymentDetails = JSON.stringify(detailObj);

// Call API
$.ajax({
  url: strUrlDPI + "/invoice/apply",
  type: "POST",
  contentType: "application/json;charset=UTF-8",
  dataType: "JSON",
  data: paymentDetails,
  timeout:10000,
  success: function(res) {
    // For implementation details, see the Samsung Checkout Sample Application
    console.log("success : " + JSON.stringify(res));
  },
  error: function(jqXHR, ajaxOptions, thrownError, request, error) {
    console.log("[Error] thrownError:"+thrownError+";error:"+error+";[Message]:"+jqXHR.responseText);

detailObj.OrderTotal = productsList.ItemDetails[selectedItem].Price.toString(); // Change datatype to string
detailObj.OrderCurrencyID = productsList.ItemDetails[selectedItem].CurrencyID;
//detailObj.OrderID = "YOUR_ORDER_ID"; // optional value
var UniqueCustomId = webapis.sso.getLoginUid(); // Unique ID for this user
detailObj.OrderCustomID = UniqueCustomId; // Same value as "CustomID" parameter for "invoice/list"

var paymentDetails = JSON.stringify(detailObj);
webapis.billing.buyItem(appId, serverType, paymentDetails,
  function(data) {
    // For implemention details, see the Samsung Checkout Sample Application
