Introduction

PayCross has a REST-ful API. To accept payments you need to send requests of a format specified for each transaction type and endpoint. However, regardless the type, each request to PayCross API must meet the following requirements:

• Use HTTP Basic authentication with Shop ID and Secret Key as a username and a password respectively;
• Add the Content-Type: application/json and Accept: application/json headers;
• Make a JSON-serialized body;
• Use the UTF-8 encoding.

Mandatory request parameters are labeled as * required. Non-labeled parameters are considered optional.
