## Requestbody- + Pfad-Parameter { #request-body-path-parameters }

Sie können Pfad-Parameter und den Requestbody gleichzeitig deklarieren.

**FastAPI** erkennt, dass Funktionsparameter, die mit Pfad-Parametern übereinstimmen, **vom Pfad genommen** werden sollen, und dass Funktionsparameter, welche Pydantic-Modelle sind, **vom Requestbody genommen** werden sollen.
