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:

```Python

2F18          ; mapped                 ; 535C          # 3.0  KANGXI RADICAL DIVINATION
2F19          ; mapped                 ; 5369          # 3.0  KANGXI RADICAL SEAL
2F1A          ; mapped                 ; 5382          # 3.0  KANGXI RADICAL CLIFF
2F1B          ; mapped                 ; 53B6          # 3.0  KANGXI RADICAL PRIVATE

Lo único nuevo es `callbacks=invoices_callback_router.routes` como un argumento para el *decorador de path operation*. Veremos qué es eso a continuación.
