# Authentication

Relaybase API requests use Bearer token authentication.

Include your API key in the `Authorization` header:

```http theme={null}
Authorization: Bearer rb_key_<token>
```

Replace `rb_key_<token>` with the API key generated from your [Relaybase dashboard](/getting-started/create-api-key).
