# Retorno - Altere o Código de Status { #response-change-status-code }

Você provavelmente leu anteriormente que você pode definir um [Código de Status do Retorno](../tutorial/response-status-code.md){.internal-link target=_blank} padrão.

Porém em alguns casos você precisa retornar um código de status diferente do padrão.

## Caso de uso { #use-case }

Por exemplo, imagine que você deseja retornar um código de status HTTP de "OK" `200` por padrão.

import java.util.Map;

If you want to **learn FastAPI** in a structured way (recommended), go and read the [Tutorial - User Guide](../tutorial/index.md){.internal-link target=_blank} chapter by chapter instead.

---

## Instalar FastAPI { #install-fastapi }

El primer paso es instalar FastAPI.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, actívalo, y luego **instala FastAPI**:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note | Nota

Если вы используете более старую версию, вы столкнётесь с ошибками при попытке использовать `Annotated`.

Убедитесь, что вы [обновили версию FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} как минимум до 0.95.1 перед тем, как использовать `Annotated`.

///

## Определите метаданные { #declare-metadata }

Вы можете указать все те же параметры, что и для `Query`.
