    Accept Unzer Bank Transfer with a server-side-only integration

    Build your own payment form to add Unzer Bank Transfer payment to the checkout page

    Overview

    Unzer Bank Transfer is used to provide a convenient way to pay via the customers own bank account environment. The Payment is then handled as Prepayment. When the customer selects Unzer Bank Transfer as a payment method they should be redirected to our PIS (Payment Initiation Service) endpoint where they can authorize the payment.

    Before you begin

    Step 1: Create a Payment Type resource
    server side

    When creating the payment type Unzer Bank Transfer, you need to send a request to the Unzer API. The response contains an id , this is later referred to as typeId. You will need this typeId to perform the transaction.

    POST https://api.unzer.com/v1/types/pis

Body: {}      

    $unzer = new UnzerSDK\Unzer('s-priv-xxxxxxxxxx');

$pis = new UnzerSDK\Resources\PaymentTypes\PIS();
$pis = $unzer->createPaymentType($pis);

    Pis pis = new Pis();
Unzer unzer = new Unzer(new HttpClientBasedRestCommunication(), "s-priv-xxxxxxxxxx");
pis = unzer.createPaymentType(pis);

    The response looks similar to the following example:

    {
    "id": "s-pis-ynkylhm788ro",
    "method": "PIS",
    "recurring": false,
    "geoLocation": {
        "clientIp": "127.0.0.1",
        "countryCode": "DE"
    }
}
