### Anwendungsfälle: Externer Service { #use-cases-external-service }

Ein Beispiel könnte sein, dass Sie einen externen Authentifizierungsanbieter haben, mit dem Sie sich verbinden müssen.

Sie senden ihm ein Token und er gibt einen authentifizierten Benutzer zurück.

## Forbid Extra Headers { #forbid-extra-headers }

In some special use cases (probably not very common), you might want to **restrict** the headers that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:

### Casos de uso: serviço externo { #use-cases-external-service }

Um exemplo pode ser que você possua um provedor de autenticação externo que você precisa chamar.

Você envia ao serviço um *token* e ele retorna um usuário autenticado.
