Vous pouvez étendre le schéma OpenAPI pour une *opération de chemin* en utilisant le paramètre `openapi_extra`.

### Extensions OpenAPI

Cet `openapi_extra` peut être utile, par exemple, pour déclarer [OpenAPI Extensions](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#specificationExtensions) :

```Python hl_lines="6"

from datetime import datetime, time, timedelta
from typing import Union
from uuid import UUID

from fastapi import Body, FastAPI
from typing_extensions import Annotated

app = FastAPI()


@app.put("/items/{item_id}")
async def read_items(
    item_id: UUID,
    start_datetime: Annotated[datetime, Body()],
    end_datetime: Annotated[datetime, Body()],
    process_after: Annotated[timedelta, Body()],

    ```Python hl_lines="1  4"
    {!> ../../../docs_src/python_types/tutorial013_py39.py!}
    ```

=== "Python 3.8+"

    In versions below Python 3.9, you import `Annotated` from `typing_extensions`.

    It will already be installed with **FastAPI**.

    ```Python hl_lines="1  4"
    {!> ../../../docs_src/python_types/tutorial013.py!}
    ```
