    * Générant automatiquement des **erreurs** renvoyées au client quand la donnée est invalide.
* **Documenter** l'API avec OpenAPI :
    * ce qui ensuite utilisé par les interfaces utilisateur automatiques de documentation interactive.

Tout cela peut paraître bien abstrait, mais ne vous inquiétez pas, vous verrez tout ça en pratique dans [Tutoriel - Guide utilisateur](tutorial/index.md){.internal-link target=_blank}.

If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:

## Déclarer des métadonnées supplémentaires

On peut aussi ajouter plus d'informations sur le paramètre.

Ces informations seront incluses dans le schéma `OpenAPI` généré et utilisées par la documentation interactive ou les outils externes utilisés.

/// note

Gardez en tête que les outils externes utilisés ne supportent pas forcément tous parfaitement OpenAPI.

RUN $env:Path += \";$env:ProgramFiles\\google-cloud-sdk\\bin\"; \
    [Environment]::SetEnvironmentVariable('Path', $env:Path, [EnvironmentVariableTarget]::Machine);
# Re-enable prompts for interactive use.
ENV CLOUDSDK_CORE_DISABLE_PROMPTS=""

# MSYS attempts to use non-cmd versions, which aren't meant for Windows

```

/// tip

To declare a query parameter with a type of `list`, like in the example above, you need to explicitly use `Query`, otherwise it would be interpreted as a request body.

///

The interactive API docs will update accordingly, to allow multiple values:

<img src="/img/tutorial/query-params-str-validations/image02.png">

When you see the automatic docs, you can check that the input model and output model will both have their own JSON Schema:

<img src="/img/tutorial/response-model/image01.png">

And both models will be used for the interactive API documentation:

## Other Return Type Annotations { #other-return-type-annotations }

* **Validate data**: coming from each request:
    * Generating **automatic errors** returned to the client when the data is invalid.
* **Document** the API using OpenAPI:
    * which is then used by the automatic interactive documentation user interfaces.

This might all sound abstract. Don't worry. You'll see all this in action in the [Tutorial - User Guide](tutorial/index.md){.internal-link target=_blank}.
