# Intro

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.

Dive a little deeper and start exploring our API reference to get an idea of everything that's possible with the API:
