Introduction

Our API is based on the REST software architectural style and provides a secure and comfortable way to perform payments.

API errors are indicated by the corresponding HTTP response codes. This topic is further described in the section Error Handling.

In addition to our payment solutions, the API supports multiple features like our Auxiliary Services. Have a look into our Documentation to gain a deeper understanding of our various products.

info

We recommend setting a minimum timeout of 90 seconds, even though API requests are expected to return a response much faster.
Having a 90 second timeout interval allows handling of delays dependent on different queries and responses from external systems and payment providers.
