## Recapitulando

Você pode adicionar múltiplos parâmetros de corpo para sua *função de operação de rota*, mesmo que a requisição possa ter somente um único corpo.

E o **FastAPI** vai manipulá-los, mandar para você os dados corretos na sua função, e validar e documentar o schema correto na *operação de rota*.

Você também pode declarar valores singulares para serem recebidos como parte do corpo.
