/// tip

The `callback_url` query parameter uses a Pydantic [Url](https://docs.pydantic.dev/latest/api/networks/) type.

///

The only new thing is the `callbacks=invoices_callback_router.routes` as an argument to the *path operation decorator*. We'll see what that is next.

## Detalles Técnicos { #technical-details }

Solo un detalle técnico para los nerds curiosos. 🤓

Por debajo, en la especificación técnica ASGI, esto es parte del [Protocolo de Lifespan](https://asgi.readthedocs.io/en/latest/specs/lifespan.html), y define eventos llamados `startup` y `shutdown`.

/// tip | Dica

O parâmetro de consulta `callback_url` usa um tipo Pydantic [Url](https://docs.pydantic.dev/latest/api/networks/).

///

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.

Вы можете использовать атрибут `model_config`, который принимает `dict`, как описано в [Документация Pydantic: Конфигурация](https://docs.pydantic.dev/latest/api/config/).

Вы можете задать `"json_schema_extra"` с `dict`, содержащим любые дополнительные данные, которые вы хотите видеть в сгенерированной JSON Schema, включая `examples`.
