## Exclude from OpenAPI

To exclude a *path operation* from the generated OpenAPI schema (and thus, from the automatic documentation systems), use the parameter `include_in_schema` and set it to `False`:

```Python hl_lines="6"
{!../../docs_src/path_operation_advanced_configuration/tutorial003.py!}
