$isValidPayment = $e2Payment->returnAuthcodeIsValid($_GET);You can also send return parameters as array instead of using $_GET superglobal.
If return code is not valid, you can get validation errors.
$errorReasons = $e2Payment->getErrors();This return array of all error reasons in return authcode validation.
To get status of payment, paid or not.
$isPaid = $e2Payment->isPaid($_GET);If customer doesn't return back after payment, status can be verified from capturing payment data from notify url. Return authcode validation is similar than success and cancelled payment, but you also need determine payment status.
$isValidPayment = $e2Payment->returnAuthcodeIsValid($_GET);
if (!$isValidPayment) {
// code to handle invalid validation.
}
$isPaid = $e2Payment->isPaid($_GET);
// Code to handle paid/cancelled status for order.You should save payment id from payment to order details. This id is used for making refunds, and is always unique. Paytrail customer care can also use payment id to track order in case of any problems. Payment id can be also used to get payment details from Merchant Panel.
