### Documentation automatique

                If you provide a custom operation ID, you need to make sure it is
                unique for the whole API.

                You can customize the
                operation ID generation with the parameter
                `generate_unique_id_function` in the `FastAPI` class.

The same way, there are many compatible tools. Including code generation tools for many languages.
