Introduction to FCFpay API

Welcome to the FCFpay API documentation.

In this document we will take you through the process of making requests to FCF Pay Merchant's API so you can set-up a custom installation on your website, to allow your customers to pay you with cryptocurrencies.

FCF Pay can be integrated into any system using the API calls.
