## Integrated with OpenAPI { #integrated-with-openapi }

All the request declarations, validations and requirements of your dependencies (and sub-dependencies) will be integrated in the same OpenAPI schema.

So, the interactive docs will have all the information from these dependencies too:

## Upgrading the FastAPI versions { #upgrading-the-fastapi-versions }

You should add tests for your app.

With **FastAPI** it's very easy (thanks to Starlette), check the docs: [Testing](../tutorial/testing.md){.internal-link target=_blank}

After you have tests, then you can upgrade the **FastAPI** version to a more recent one, and make sure that all your code is working correctly by running your tests.

Então, se você acessar as URLs em `/openapi.json`, `/docs` ou `/redoc`, você receberá apenas um erro `404 Não Encontrado` como:

```JSON
{
    "detail": "Not Found"
}

## Les modèles Pydantic

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> est une bibliothèque Python pour effectuer de la validation de données.

Vous déclarez la forme de la donnée avec des classes et des attributs.

Chaque attribut possède un type.

## Проверка в действии

Запустите сервер и перейдите к документации: <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

Вы увидите пользовательский интерфейс вида:

Пройдите авторизацию так же, как делали раньше.

그리고 `Response`는 헤더와 쿠키를 설정하는 데 자주 사용될 수 있으므로, **FastAPI**는 `fastapi.Response`로도 이를 제공합니다.

## 커스텀 헤더

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">‘X-’ 접두어를 사용하여</a> 커스텀 사설 헤더를 추가할 수 있습니다.

Usando la información anterior, puedes usar la misma función de utilidad para generar el esquema de OpenAPI y sobrescribir cada parte que necesites.

Por ejemplo, vamos a añadir <a href="https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo" class="external-link" target="_blank">la extensión OpenAPI de ReDoc para incluir un logo personalizado</a>.
