A única novidade é o `callbacks=invoices_callback_router.routes` como argumento do decorador da *operação de rota*. Veremos o que é isso a seguir.

## Documentando o callback { #documenting-the-callback }

O código real do callback dependerá muito da sua própria aplicação de API.

E provavelmente variará muito de um aplicativo para o outro.

Poderia ser apenas uma ou duas linhas de código, como:
