Я пытаюсь внедрить приемник PayPal IPN. Проблема в том, что, что бы я ни пытался, я все еще получаю НЕВЕРНЫЙ ответ от IPN Simulator. Я просматривал многие форумы, но никто не помогал. Кто-нибудь знает, что может быть проблемой?PayPal IPN симулятор, возвращающий отрицательный ответ
См. Мой код ниже. YII_DEBUG is true USE_SANDBOX is true Я пробовал реализацию с или без cacert.pem, ничего не работает.
public function actionProcessPayment()

// issues with array data in POST. Reading raw POST data from input stream instead.
