Payment Notification

After the payment, a request containing payment information will be sent to the URL specified in your store settings.

Key	Description
shop_id	Public project key
amount	Payment amount
order_id	Order identifier
payment_system	Payment system
currency	Payment currency (RUB, USD, EUR)
test	If specified during payment
sign	Request signature

The signature is formed in the same way as when creating the form, but all fields are included in the hash formation, for example:


   <?php 
      $secret = 'GB%^&*YJni677';
      $data = $_POST;
      unset($data['sign']);
      ksort($data);
      $str = http_build_query($data);
      $sign = md5($str . $secret);
    ?>
