非常简单，只需执行statusAPI.php文件（由CCAvenue共享），并输入所需参数。

$working_key = '*****'; //Shared by CCAVENUES
$access_code = '*****'; //Shared by CCAVENUES

$merchant_json_data = array(
   'order_no' => '', //your app's internal order no
   'reference_no' =>'' //ccavenue tracking no
);

你可以使用下面的简单函数和必要的参数。

function processStatusCallback() {
    // Read the callback data from the input stream
    $callbackData = file_get_contents("php://input");
    
    // Parse the JSON data
    $data = json_decode($callbackData, true);
    
    // Verify the authenticity of the callback (assuming secure hash validation)
    $secureHash = '########'; // Replace with your actual secure hash
    
    // Generate hash from the received data
    $generatedHash = hash('sha256', implode('|', $data) . '|' . $secureHash);
    
    // Compare generated hash with received hash
    if ($data['secure_hash'] === $generatedHash) {
        // Hash validation successful, process the payment status
        $orderId = $data['order_id'];
        $paymentStatus = $data['payment_status'];
                
        // Send a response back to CCAvenue
        echo json_encode(['status' => 'success']);
    } else {        
        // Send an error response back to CCAvenue
        echo json_encode(['status' => 'error', 'message' => 'Invalid secure hash']);
    }
}

在.net C#中获取ccavenue付款状态非常简单，使用生产环境的live url，使用测试环境的test url。
