## La aplicación normal de **FastAPI** { #the-normal-fastapi-app }

Primero veamos cómo se vería la aplicación API normal antes de agregar el callback.

Tendrá una *path operation* que recibirá un cuerpo `Invoice`, y un parámetro de query `callback_url` que contendrá la URL para el callback.

{* ../../docs_src/schema_extra_example/tutorial003_an_py310.py hl[22:29] *}

### Ejemplo en la interfaz de documentación { #example-in-the-docs-ui }

Con cualquiera de los métodos anteriores se vería así en los `/docs`:

<img src="/img/tutorial/body-fields/image01.png">

### `Body` con múltiples `examples` { #body-with-multiple-examples }

Por supuesto, también puedes pasar múltiples `examples`:

/// warning | Advertencia

Una `Response` devuelta directamente por tu *path operation function* no se documentará en OpenAPI (por ejemplo, el `Content-Type` no se documentará) y no será visible en la documentación interactiva automática.

///

/// info | Información

Por supuesto, el `Content-Type` header real, el código de estado, etc., provendrán del objeto `Response` que devolviste.

///

## Separando testes { #separating-tests }

Em uma aplicação real, você provavelmente teria seus testes em um arquivo diferente.

E sua aplicação **FastAPI** também pode ser composta de vários arquivos/módulos, etc.
