README

A Pay.nl payment provider for the Canvas framework. Part of the Canvas payments ecosystem.

Installation

composer require quellabs/canvas-payments-paynl

Architecture

This package sits between the Pay.nl API and your application. Your application only ever touches the contracts layer — it never depends on this package directly. PaymentRouter (from quellabs/canvas-payments) discovers this package automatically via composer metadata and routes payment calls to it.

Your Application
      │
      ▼
PaymentRouter               (quellabs/canvas-payments — discovery + routing)
      │
      ▼
PaymentInterface            (quellabs/canvas-payments-contracts)
      │
      ▼
Pay.nl                      (this package — implements the interface)
      │
      ▼
PayNLGateway                (raw Pay.nl TGU API calls)

Exchange processing is decoupled from your application via signals. When Pay.nl calls the exchange URL, the package emits a payment_exchange signal carrying a PaymentState. Your application listens for that signal and handles it.

Configuration

Create config/paynl.php in your Canvas application:

return [
    'token_code'        => '',     // AT-xxxx-xxxx
    'api_token'         => '',     // 40-character hash
    'service_id'        => '',     // SL-xxxx-xxxx
    'test_mode'         => false,
    'return_url'        => 'https://example.com/order/thankyou',
    'cancel_return_url' => 'https://example.com/order/cancelled',
    'exchange_url'      => 'https://example.com/webhooks/paynl',
    'default_currency'  => 'EUR',
];

Supported payment methods

Payment methods must be activated for your sales location in the Pay.nl admin panel before use.

Usage

Initiating a payment

use Quellabs\Payments\Contracts\PaymentInterface;
use Quellabs\Canvas\Controllers\BaseController;
use Quellabs\Payments\Contracts\PaymentRequest;
use Quellabs\Payments\Contracts\PaymentInitiationException;

class CheckoutController extends BaseController {

    public function __construct(private PaymentInterface $router) {}

    /**
     * @Route("...")
     */
    public function checkout(): Response {
        $request = new PaymentRequest(
            paymentModule: 'paynl_ideal',
            amount:        999,   // in minor units — €9.99
            currency:      'EUR',
            description:   'Order #12345',
            reference:     'order-12345',
        );

        try {
            $result = $this->router->initiate($request);
            return $this->redirect($result->redirectUrl);
        } catch (PaymentInitiationException $e) {
            // handle error
        }
    }
}

Handling refunds

use Quellabs\Payments\Contracts\RefundRequest;
use Quellabs\Payments\Contracts\PaymentRefundException;

// Full refund — omit amount
$request = new RefundRequest(
    paymentReference: $state->transactionId,   // UUID from payment_exchange signal
    paymentModule:    'paynl_ideal',
    amount:           null,                    // null = full refund
    currency:         'EUR',
    description:      'Full refund for order #12345',
);

// Partial refund — provide amount in minor units
$request = new RefundRequest(
    paymentReference: $state->transactionId,
    paymentModule:    'paynl_ideal',
    amount:           500,                     // €5.00
    currency:         'EUR',
    description:      'Partial refund for order #12345',
);

try {
    $result = $this->router->refund($request);
    echo $result->refundId;
} catch (PaymentRefundException $e) {
    // handle error
}

Listening for payment state changes

use Quellabs\Canvas\Annotations\ListenTo;
use Quellabs\Payments\Contracts\PaymentState;
use Quellabs\Payments\Contracts\PaymentStatus;

class OrderService {

    /**
     * @ListenTo("payment_exchange")
     */
    public function onPaymentExchange(PaymentState $state): void {
        match ($state->state) {
            PaymentStatus::Paid     => $this->markPaid($state->transactionId, $state->valuePaid),
            PaymentStatus::Canceled => $this->markCanceled($state->transactionId),
            PaymentStatus::Refunded => $this->handleRefund($state),
            PaymentStatus::Failed   => $this->markFailed($state->transactionId),
            default                 => null,
        };
    }
}
