  9. Client / Server Side Components Client Components Server-Side Components

  10. How Digital Goods Work Fetch the token Display login lightbox Commit the payment Verify the payment

  18. Session Breakdown The Architecture The Implementation The Product Webhooks

  19. The Project Code Base https://github.com/paypal/html5-dg

  20. File Architecture index.html: Sample integration client/pptransact.js: Core front-end server/[LANG]/cancel.[EXT]: Display when user cancels server/[LANG]/common.[EXT]: Common functions and variables. server/[LANG]/identity.[EXT]: Client identity hooks server/[LANG]/inventory.[EXT]: Client inventory hooks server/[LANG]/success.[EXT]: Display on payment success server/[LANG]/pptransact.[EXT]: Server-side controller

  21. Setup Sandbox User Accounts https://developer.paypal.com/

  22. Library & Toolkit Setup Attach the script includes <script src="https://www.paypalobjects.com/js/ external/dg.js"></script> <script src="client/jquery-min.js" type="text/javascript"></script> <script src="client/pptransact.js"></script>

  23. Picking the Server-Side Language Pick Language and Mobile Support pptransact.init('py', true); //mobile pptransact.init('java'); //non-mobile

  24. Creating a Billing Handler pptransact.bill({ userId:'[USER ID]', itemId:'[ITEM ID]', itemQty:'[ITEM QUANTITY]', successCallback: function(data){ //bill success }, failCallback: function(data){ //bill cancelled } });

  25. How the Billing Flow Works Bill Digital Goods Success / Fail Billing Request Product Storage Store Details User Notification Notify User

  26. Creating a Verification Handler pptransact.verify({ userId:'[USER ID]', itemId:'[ITEM ID]', successCallback: function(data){ //verify success }, failCallback: function(data){ //verify failed } });

  27. How the Verification Flow Works Get Data Product Storage Success / Fail Verify Purchase Verification Request Digital Goods Success / Fail User Notification Notify User

  28. Session Breakdown The Architecture The Implementation The Product Webhooks

  29. Identity and Payment Hooks Client Identity Server PayPal Identity Server

  30. Identity: verifyUser function verifyUser($userId = 0){ $YourSessionUserId = '888888'; $returnVal = ($userId == $YourSessionUserId) ? true : false; return $returnVal; }

  31. Identity: getUserId function getUserId(){ $result = "888888"; return $result; }

  32. Payment: recordPayment function recordPayment($paymentObj = ""){ $userId = $paymentObj["userId"]; $itemId = $paymentObj["itemId"]; $transactionId = $paymentObj["transactionId"]; $paymentStatus = $paymentObj["paymentStatus"]; $orderTime = $paymentObj["orderTime"]; //INSERT YOUR CODE TO SAVE THE PAYMENT DATA }

  33. Payment: verifyPayment function verifyPayment($userId = 0, $itemId = 0){ $result = false; //INSERT YOUR CODE TO QUERY PAYMENT DATA AND //RETURN TRUE if MATCH FOUND return $result; }

  34. Payment: getPayment function getPayment($userId = 0, $itemId = 0){ //INSERT CODE TO QUERY AND RETURN PAYMENT STRUCTURE $returnObj = array("success" => true, "error" => "", "transactionId" => "12345678", "orderTime" => "2011-09-29T04:47:51Z", "paymentStatus" => "Pending", "itemId" => "123", "userId" => "888888"); return $returnObj; }

  35. Inventory Management Hooks Client Inventory Server PayPal Digital Goods Payment

  36. Inventory: getItem function getItem($itemId){ $items = array( array(name => "Mega Shields", number => "123", qty => "1", taxamt => "0", amt => "1.00", desc => "Unlock the power!", category => "Digital"), ...); $returnObj = array(); for ($i = 0; $i < count($items); $i++){ if ($items[$i]['number'] == $itemId){ $returnObj = $items[$i]; } } return $returnObj; }

  37. Is the Toolkit Right for You? HTML5 Support? Need to Accept Payments? Accepting Digital Goods?

  38. A Few Links The HTML5 Toolkit https://github.com/paypal/html5-dg The PayPal Sandbox (Create Test Users) https://developer.paypal.com/ JSWars Code and Demo http://29a.ch/jswars/
