# Identity: Window API

## Introduction

This guide describes the Window API, which is an essential component of integrating with the DeSo Identity Service.

If you haven't yet read through the [identity](https://docs.deso.org/deso-identity/identity "mention") and [concepts](https://docs.deso.org/deso-identity/identity/concepts "mention") guides, it would be helpful to do so prior to reading this documentation.

The Window API guide consists of two subpages, which should give you a comprehensive view of the API:

* [basics](https://docs.deso.org/deso-identity/window-api/basics "mention") guide outlines the fundamentals of integrating with the Window API
* [endpoints](https://docs.deso.org/deso-identity/window-api/endpoints "mention") is an exhaustive list of all API endpoints.

Upon finishing reading about the Window API, we recommend taking a look at the [iframe-api](https://docs.deso.org/deso-identity/iframe-api "mention"), especially if you're developing a web application.

And if you're creating a mobile app, check out our [mobile-integration](https://docs.deso.org/deso-identity/identity/mobile-integration "mention") guide next.
