# Corpo - Múltiplos parâmetros { #body-multiple-parameters }

Agora que nós vimos como usar `Path` e `Query`, veremos usos mais avançados de declarações no corpo da requisição.

## Misture `Path`, `Query` e parâmetros de corpo { #mix-path-query-and-body-parameters }

Primeiro, é claro, você pode misturar `Path`, `Query` e declarações de parâmetro no corpo da requisição livremente e o **FastAPI** saberá o que fazer.
