# Platform API Overview

> RESTful API for managing your Fourthwall shop programmatically

The Fourthwall Platform API is a RESTful API that allows you to manage various aspects of your shop.

It can be accessed either directly using your own API key (this gives you full access to your own shop) or indirectly through OAuth for multi-shop apps.
