# API Reference

Learn about the Coop API, including the REST API endpoints your platform uses to integrate with Coop.

All endpoints require an API key passed as an HTTP header on every request:

```http
X-API-KEY: <<apiKey>>
Content-Type: application/json
```

You can find or rotate your API key under **Settings** → **API Keys** in the Coop UI. For details on verifying the signatures Coop adds to outgoing webhook requests, see [API Keys & Authentication](../development/api-auth.md).
