# Eine Response direkt zurückgeben { #return-a-response-directly }

Wenn Sie eine **FastAPI** *Pfadoperation* erstellen, können Sie normalerweise beliebige Daten davon zurückgeben: ein `dict`, eine `list`, ein Pydantic-Modell, ein Datenbankmodell, usw.

Standardmäßig konvertiert **FastAPI** diesen Rückgabewert automatisch nach JSON, mithilfe des `jsonable_encoder`, der in [JSON-kompatibler Encoder](../tutorial/encoder.md){.internal-link target=_blank} erläutert wird.

Adotar temporariamente esse ponto de vista (do *desenvolvedor externo*) pode ajudar a perceber mais facilmente onde colocar os parâmetros, o modelo Pydantic para o corpo, para a resposta, etc. para essa *API externa*.

### Crie um `APIRouter` de callback { #create-a-callback-apirouter }

Primeiro crie um novo `APIRouter` que conterá um ou mais callbacks.
