## Zusammenfassung { #recap }

## Responses Adicionales { #additional-responses }

Probablemente has visto cómo declarar el `response_model` y el `status_code` para una *path operation*.

Eso define los metadatos sobre el response principal de una *path operation*.

También puedes declarar responses adicionales con sus modelos, códigos de estado, etc.

Wenn Sie eine Gruppe verwandter **Header-Parameter** haben, können Sie ein **Pydantic-Modell** erstellen, um diese zu deklarieren.

Dadurch können Sie das **Modell an mehreren Stellen wiederverwenden** und auch Validierungen und Metadaten für alle Parameter gleichzeitig deklarieren. 😎

/// note | Hinweis

Dies wird seit FastAPI Version `0.115.0` unterstützt. 🤓
