# Introduction

Spree comes with a fully-featured API that allows it to operate in a fully headless mode. This means that you can use Spree as a backend and build your custom storefront, mobile app, or any other application that needs to interact with an e-commerce platform.

## APIs

Currently Spree includes 2 APIs:

<CardGroup cols={2}>
  <Card title="Storefront API" href="storefront">
    Designed to allow customers to interact with the store via external applications (e.g. Vue Storefront or a dedicated mobile app)
  </Card>

  <Card title="Platform API" href="platform">
    Provides management capabilities, allowing third party apps to perform actions otherwise available via the admin panel.
  </Card>
</CardGroup>

### Legacy REST API v1

Legacy REST API v1 was extracted to `spree_api_v1` gem. It is not recommended to use it in new projects, but it's still available for existing ones.
