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.'; } ?>
