## Documenting webhooks with **FastAPI** and OpenAPI { #documenting-webhooks-with-fastapi-and-openapi }

With **FastAPI**, using OpenAPI, you can define the names of these webhooks, the types of HTTP operations that your app can send (e.g. `POST`, `PUT`, etc.) and the request **bodies** that your app would send.

### Aplicação de nível superior

Primeiro, crie a aplicação principal, de nível superior, **FastAPI**, e suas *operações de rota*:

{* ../../docs_src/sub_applications/tutorial001.py hl[3,6:8] *}

### Sub-aplicação

Em seguida, crie sua sub-aplicação e suas *operações de rota*.
