API Overview

1. Overview

The core of FusionAuth is a set of RESTful APIs that allow you to quickly integrate login, registration and advanced User management features into your application. The FusionAuth web UI is built upon these APIs, with the exception of managing API keys everything in the UI is available through an API.

On this page you will find links to each of the API groups and a general overview of the API status codes you can expect back from each API. Each API will also document specific status codes and the specific meaning of the status code.
