# Body – Mehrere Parameter { #body-multiple-parameters }

Nun, da wir gesehen haben, wie `Path` und `Query` verwendet werden, schauen wir uns fortgeschrittenere Verwendungsmöglichkeiten von <abbr title="Anfragekörper">Requestbody</abbr>-Deklarationen an.

## `Path`-, `Query`- und Body-Parameter vermischen { #mix-path-query-and-body-parameters }

OpenAPI requiere que cada operation ID sea único a través de todas las *path operations*, por lo que FastAPI usa el **nombre de la función**, el **path**, y el **método/operación HTTP** para generar ese operation ID, porque de esa manera puede asegurarse de que los operation IDs sean únicos.
