Isso é bastante similar ao caso do HTTP status code 200 (do 200 ao 299). Esses "200" status codes significam que, de algum modo, houve sucesso na requisição.

Os status codes na faixa dos 400 significam que houve um erro por parte do cliente.

Você se lembra de todos aqueles erros (e piadas) a respeito do "**404 Not Found**"?

## Use o `HTTPException`

	Um token "bearer" não é a única opção.

	Mas é a melhor no nosso caso.

	E talvez seja a melhor para a maioria dos casos, a não ser que você seja um especialista em OAuth2 e saiba exatamente o porquê de existir outras opções que se adequam melhor às suas necessidades.

	Nesse caso, **FastAPI** também fornece as ferramentas para construir.

      // Server sent a 100-continue even though we did not request one. Try again to read the
      // actual response status.
      code == 100 -> true

      // Handle Processing (102) & Early Hints (103) and any new codes without failing
      // 100 and 101 are the exceptions with different meanings
      // But Early Hints not currently exposed
      code in (102 until 200) -> true

      else -> false
    }

Dieser Statuscode wird in der Response verwendet und zum OpenAPI-Schema hinzugefügt.

/// note | "Technische Details"

Sie können auch `from starlette import status` verwenden.

**FastAPI** bietet dieselben `starlette.status`-Codes auch via `fastapi.status` an, als Annehmlichkeit für Sie, den Entwickler. Sie kommen aber direkt von Starlette.

Dies kann es Ihren Benutzern viel einfacher machen, **deren APIs zu implementieren**, um Ihre **Webhook**-Requests zu empfangen. Möglicherweise können diese sogar einen Teil des eigenem API-Codes automatisch generieren.
