Authorize.Net Код ошибки повторяющегося биллинга

Недавно я интегрировал авторизацию Authorize.net в сайт. Теперь я должен интегрироваться еще раз, но с регулярным ежемесячным выставлением счетов. Я использовал sdk, который они предоставляют в качестве примера, и мне было интересно, может ли кто-нибудь сделать какую-то проверку работоспособности и сказать мне, где я отказываюсь.

Примечание: я новичок в php.

Это код, который они предоставляют

    <?php
require 'vendor/autoload.php';
require_once 'constants/SampleCodeConstants.php';
use net\authorize\api\contract\v1 as AnetAPI;
use net\authorize\api\controller as AnetController;
date_default_timezone_set('San Juan/Puerto Rico');

define("AUTHORIZENET_LOG_FILE", "phplog");

function createSubscription($intervalLength)
{
$merchantAuthentication = new AnetAPI\MerchantAuthenticationType();
$merchantAuthentication->setName(\SampleCodeConstants::MERCHANT_LOGIN_ID);
$merchantAuthentication->setTransactionKey(\SampleCodeConstants::MERCHANT_TRANSACTION_KEY);

$refId = 'ref' . time();

// Subscription Type Info
$subscription = new AnetAPI\ARBSubscriptionType();
$subscription->setName("Sample Subscription");

$interval = new AnetAPI\PaymentScheduleType\IntervalAType();
$interval->setLength($intervalLength);
$interval->setUnit("days");

$paymentSchedule = new AnetAPI\PaymentScheduleType();
$paymentSchedule->setInterval($interval);
$paymentSchedule->setStartDate(new DateTime('2020-08-30'));
$paymentSchedule->setTotalOccurrences("12");
$paymentSchedule->setTrialOccurrences("1");

$subscription->setPaymentSchedule($paymentSchedule);
$subscription->setAmount(rand(1,99999)/12.0*12);
$subscription->setTrialAmount("0.00");

$creditCard = new AnetAPI\CreditCardType($cardDetails);
$creditCard->setCardNumber("card-number");
$creditCard->setExpirationDate( $cardDetails["year"] . "-" . $cardDetails["month"]);
$creditCard->setCardCode($cardDetails["cardCode"]);
$payment = new AnetAPI\PaymentType();
$payment->setCreditCard($creditCard);

// Subscription //
$subscription->setPayment($payment);

$order = new AnetAPI\OrderType();
$order->setInvoiceNumber("1234354");
$order->setDescription("Description of the subscription");
$subscription->setOrder($order);


// Duda en esta Programación //
$billTo = new AnetAPI\NameAndAddressType();
$billTo->setFirstName("John");
$billTo->setLastName("Smith");
$billTo->setCompany("");

$subscription->setBillTo($billTo);

$request = new AnetAPI\ARBCreateSubscriptionRequest();
$request->setmerchantAuthentication($merchantAuthentication);
$request->setRefId($refId);
$request->setSubscription($subscription);
$controller = new AnetController\ARBCreateSubscriptionController($request);

$response = $controller->executeWithApiResponse( \net\authorize\api\constants\ANetEnvironment::SANDBOX);

if (($response != null) && ($response->getMessages()->getResultCode() == "Ok") )
{
echo "SUCCESS: Subscription ID : " . $response->getSubscriptionId() . "\n";
}
else
{
echo "ERROR :  Invalid response\n";
$errorMessages = $response->getMessages()->getMessage();
echo "Response : " . $errorMessages[0]->getCode() . "  " .$errorMessages[0]->getText() . "\n";
}

return $response;
}

if(!defined('DONT_RUN_SAMPLES'))
createSubscription(23);

?>

Я сделал некоторые изменения, которые в прошлом работали с единой интеграцией платежей, которую я сделал. Пока это то, что я получил …

Это мой код

Я хочу знать, правильно ли я иду, если нет, какие-либо предложения о том, как интегрировать периодическое выставление счетов?
