Configuration

Add the qnb block to config/payline.php under gateways:

Usage

Charging a payment

use XLaravel\Payline\DTOs\Card;
use XLaravel\Payline\DTOs\PaymentRequest;

$data = PaymentRequest::fromPayable(
    payable: $order,
    card: new Card(
        holderName: 'John Doe',
        number: '4111111111111111',
        expiryMonth: '12',
        expiryYear: '2030',
        cvv: '123',
    ),
    installments: 1,
    customerIp: $request->ip(),
);

$response = $order->pay('qnb')->charge($data);

QNB uses a 3DS HTML form flow. On success, pay() returns a PaymentResponse with status = Pending and a redirectForm containing a self-submitting HTML form that forwards the customer to their bank's 3DS page:

if ($response->requiresRedirect()) {
    return response($response->redirectForm); // renders and auto-submits the form
}

Handling the callback

Payline handles the callback automatically via its built-in route (/payline/callbacks/qnb). After 3DS completes, QNB POSTs back to this URL. The driver verifies the response hash and the user is redirected to payline.callback_success_url or payline.callback_failure_url.

You can listen to the dispatched events for any post-payment logic:

use XLaravel\Payline\Events\PaymentSucceeded;
use XLaravel\Payline\Events\PaymentFailed;

class HandlePaymentSucceeded
{
    public function handle(PaymentSucceeded $event): void
    {
        $event->payment;     // Payment model
        $event->transaction; // Transaction model
        $event->response;    // PaymentResponse DTO
    }
}

Pre-authorization & Capture

use XLaravel\Payline\DTOs\CaptureData;
use XLaravel\Payline\Facades\Payline;

// 1. Pre-authorize (TxnType=PreAuth, 3DS flow)
$response = $order->pay('qnb')->authorize($data);

// 2. Capture later
Payline::via('qnb')->capture(
    new CaptureData(
        gatewayTransactionId: $transaction->gateway_transaction_id,
        amount: $transaction->amount,
        currency: $transaction->currency,
    ),
    $payment,
    $transaction,
);

Refund

use XLaravel\Payline\DTOs\RefundData;

Payline::via('qnb')->refund(
    new RefundData(
        gatewayTransactionId: $transaction->gateway_transaction_id,
        amount: 5000, // kuruş
        currency: 'TRY',
    ),
    $payment,
    $transaction,
);

Void (Cancel)

use XLaravel\Payline\DTOs\VoidData;

Payline::via('qnb')->void(
    new VoidData(gatewayTransactionId: $transaction->gateway_transaction_id),
    $payment,
    $transaction,
);
