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

Verás el response JSON como:

```JSON
{"message": "Hello World"}

* **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}.
