## API basics

All API requests use your website domain as the host:

```text theme={null}
https://{domain}/api/site
```

Authenticate requests with a bearer token:

```http theme={null}
Authorization: Bearer YOUR_API_KEY
User-Agent: YourApp/1.0
```

You can find the API key in your website settings under **Applications** > **API Key**.

## What you can build

Use the API to sync contacts, manage members, update store products, retrieve orders, review bookings, collect form submissions, organize subscriber lists, and configure webhook notifications.

<Note>
  The endpoint playground is available at `/endpoints`. Link developers to `/api` when they are starting from the website.
