### Create a callback `APIRouter` { #create-a-callback-apirouter }

First create a new `APIRouter` that will contain one or more callbacks.

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[1,23] *}

### Create the callback *path operation* { #create-the-callback-path-operation }

To create the callback *path operation* use the same `APIRouter` you created above.

Primeiro crie um novo `APIRouter` que conterá um ou mais callbacks.

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[1,23] *}

### Crie a *operação de rota* do callback { #create-the-callback-path-operation }

Para criar a *operação de rota* do callback, use o mesmo `APIRouter` que você criou acima.

Ela deve parecer exatamente como uma *operação de rota* normal do FastAPI:
