Introduction

Welcome to the VIA payment system.

In this instruction you will find all the information you need to successfully interact with our API. Our REST API is designed according to REST standards, making it easy to use and predictable. We strive to keep things simple and clear, so our URLs are structured logically and use HTTP response codes to clarify API errors.

When working with our API, you can use standard HTTP features such as HTTP authentication and HTTP verbs. This allows you to use existing HTTP clients and simplifies interaction with the API. All API responses are returned in JSON format, including error messages.
