Get Started

In this section, we'll walk you through a practical example of how to perform a payment request (/rest/payment) for a transaction.

There are two API integration patterns to make your first payment transaction through our API:

Payment Page Redirect

Redirect customers to a secure, hosted payment page via POST /rest/payment. Supported for methods such as Card ECOM, Wero, iDEAL, Pay by Bank, and PayPal. Recommended starting point when the method uses this redirect flow — see each method in Payment Methods.

Server-to-Server Processing

Your backend sends payment data directly to the API without a hosted payment page. This guide uses Card ECOM as the example; PCI DSS compliance is required when you handle cardholder data. Other server-to-server methods are documented under Payment Methods.

Both approaches use the same authentication method (Basic Auth) and the same endpoint structure, but the workflow differs in how the payment data is handled and how the payment result is returned.
