Custom Payment Gateways

Use the gateway option to add your own payment gateway.

initializePayment and completePayment must return a OrderPage object.

In initializePayment you can set a redirect url. The user will be redirected to this url. If you don’t set redirect the user will be sent to successPage.

site/content/config.php

return [
  'ww.merx.gateways' => [
    'my-payment-provider' => [
      'initializePayment' => function(OrderPage $virtualOrderPage): OrderPage
      {
        $sum = $virtualOrderPage->cart()->getSum();
        // do something to get a redirect url
        $redirectUrl = 'https://mypaymentprovider.com/payment/mlDquvqMQK85M1Pw',
        $virtualOrderPage->content()->update([
          'redirect' => $redirectUrl,
        ]);
        return $virtualOrderPage;
      },
      'completePayment' => function(OrderPage $virtualOrderPage, array $data): OrderPage
      {
        $virtualOrderPage->content()->update([
          'paymentComplete' => true,
          'payedDate' => date('c'),
        ]);
        return $virtualOrderPage;
      }
    ],
  ],
];

Be careful. Since $virtualOrderPage is just virtual and not yet written to the content folder you can't use $page->update() (which would write a content file). Instead you can use $page->content()->update() to update the virtual page’s content.
