# Authentication

> API key formats and scopes.

All requests use a bearer token.

```http theme={null}
Authorization: Bearer rb_live_xxxxxxxx
```

Keys are issued from the dashboard (**API keys → Create**). See the [authentication concept](/concepts/authentication) for detailed behavior, key formats, and test vs. live mode.
