    wsgi_app(*, label=None, custom_domains=None, requires_proxy_auth=False)

Decorator for registering a WSGI app with a Modal function.

Web Server Gateway Interface (WSGI) is a standard for synchronous Python web apps. It has been [succeeded by the ASGI interface](https://asgi.readthedocs.io/en/latest/introduction.html#wsgi-compatibility)
 which is compatible with ASGI and supports additional functionality such as web sockets. Modal supports ASGI via [`asgi_app`](https://modal.com/docs/sdk/py/latest/modal.asgi_app)
.

To learn how to use this decorator with popular web frameworks, see the [guide on Web Functions](https://modal.com/docs/guide/webhooks)
.

**Usage**

    from typing import Callable
    
    @app.function()
    @modal.wsgi_app()
    def create_wsgi() -> Callable:
        ...
