# Authentication

API requests are authenticated using JWT Bearer tokens. You can get a token from the [sign in](/api-reference/sign-in) endpoint.

Make sure you pass the token in the `Authorization` header of your requests:

```bash
'Authorization': 'Bearer <access_token>'
```

NextAPI use Supabase as authentication provider. You can read more about Supabase authentication [here](https://supabase.io/docs/guides/auth).
