Verify Item Purchases with the Envato API
This article focuses on how to simply and efficiently converse with Envato’s API in order to verify the authors’ customers’ purchase codes in the author’s own applications. I talk through all the steps to set up this function, covering how to create the unique API key required, using the PHP cURL function and interpreting the output.
<?php function verify_envato_purchase_code($code_to_verify) { // Your Username $username = 'USERNAME'; // Set API Key $api_key = 'API KEY'; // Open cURL channel $ch = curl_init(); // Set cURL options curl_setopt($ch, CURLOPT_URL, "http://marketplace.envato.com/api/edge/". $username ."/". $api_key ."/verify-purchase:". $code_to_verify .".json"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // Decode returned JSON $output = json_decode(curl_exec($ch), true); // Close Channel curl_close($ch); // Return output return $output; } $purchase_key = 'PURCHASE KEY TO CHECK'; $purchase_data = verify_envato_purchase_code( $purchase_key ); if( isset($purchase_data['verify-purchase']['buyer']) ) { echo '<strong>Valid License Key!</strong><br>Details;<ul>'; echo '<li>Item ID: ' . $purchase_data['verify-purchase']['item_id'] . '</li>'; echo '<li>Item Name: ' . $purchase_data['verify-purchase']['item_name'] . '</li>'; echo '<li>Buyer: ' . $purchase_data['verify-purchase']['buyer'] . '</li>'; echo '<li>License: ' . $purchase_data['verify-purchase']['licence'] . '</li>'; echo '<li>Created At: ' . $purchase_data['verify-purchase']['created_at'] . '</li>'; echo '</ul>'; } else { echo 'Invalid license key.'; } ?>
