Mas se o dado não existir, você quer criá-lo e retornar um código de status HTTP de "CREATED" `201`.

Mas você ainda quer ser capaz de filtrar e converter o dado que você retornará com um `response_model`.

Para estes casos, você pode utilizar um parâmetro `Response`.

## Use um parâmetro `Response` { #use-a-response-parameter }

It also includes what has changed, how validations are now more correct and strict, possible caveats, etc.

You can read it to understand better what has changed.

## Tests { #tests }

Make sure you have [tests](../tutorial/testing.md){.internal-link target=_blank} for your app and you run them on continuous integration (CI).

This way, you can do the upgrade and make sure everything is still working as expected.
