API Introduction

The Xpresspay API gives you access which pretty much allows you to integrate with it in your application. It strives to be RESTful and is organized around the main resources you would be interacting with - with a few notable exceptions.

Before you do anything, you should create a free Xpresspay account that you can test the API against. We will provide you with test keys that you can use to make API calls.

Sample Requests

We provide sample API calls next to each method using cURL. All you need to do is drop in your specific parameters, and you can test the calls from the command line. See this tutorial on using cURL with APIs. Of course you can use POSTMAN as well if cURL isn't your cup of tea. POSTMAN is an easy to use API development environment for making HTTP requests.
You can also download the Xpresspay Postman Collection to make testing the API easier.

Input/Output Format

Both request body data and response data are formatted as JSON. Content type for responses will always be application/json.
