Accept EPS with server-side-only integration

Build your own payment form to add EPS payment to your checkout page.

Overview

EPS payment method doesn’t require any input from the customer on the merchant website. Optionally you can include a bank selection control for the customer to pre-select their bank when making the payment. You can see an example of EPS bank selection component on our demo page.

Before you begin

• Check the basic integration requirements.
• Familiarize yourself with the general Server-side-only integration guide.

Step 1: Create a Payment Type resource [server side]

Data for the EPS payment:

Banks supported by EPS:

When creating the payment type EPS, you need to send a request to the Unzer API. The response contains an id , this is later referred to as typeId. You require this typeId to perform the transaction. As mentioned previously, bic is optional.

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

{
  "bic":"STZZATWWXXX"
}

// get the BIC from your payment form.
$unzer = new Unzer('s-priv-xxxxxxxxxx', SupportedLocale::GERMAN_GERMAN);
$eps= $unzer->createPaymentType((new EPS())->setBic($bic));

// get the BIC from your payment form.
Unzer Unzer = new Unzer("s-priv-xxxxxxxxxx");
EPS eps= heidelpayInstance.createPaymentType(new EPS(bic));

The response looks similar to the following example:

{
  "id": "s-eps-9rxdhskuhnea",
  "method": "EPS",
  "recurring": false,
  "geoLocation": {
    "clientIp": "127.0.0.1",
    "countryCode": "DE"
  },
  "bic": "STZZATWWXXX"
}
