код карты не проходит проверку в authorize.net

Я разрабатываю веб-приложение. Здесь я реализовал платежный шлюз authorize.net. Но здесь код пещеры не проверяется правильно. Если я укажу неправильный код карты, платеж будет успешным, но мне нужен результат, так как платеж отклонен

Кто-нибудь знает это? посмотреть код
