### Add the callback router

At this point you have the *callback path operation(s)* needed (the one(s) that the *external developer*  should implement in the *external API*) in the callback router you created above.

Now use the parameter `callbacks` in *your API's path operation decorator* to pass the attribute `.routes` (that's actually just a `list` of routes/*path operations*) from that callback router:

```

## Benutzerdefinierte `APIRoute`-Klasse in einem Router

Sie können auch den Parameter `route_class` eines `APIRouter` festlegen:

```Python hl_lines="26"
{!../../docs_src/custom_request_and_route/tutorial003.py!}
```

        if responses is None:
            responses = {}
        for route in router.routes:
            if isinstance(route, APIRoute):
                combined_responses = {**responses, **route.responses}
                use_response_class = get_value_or_default(
                    route.response_class,
                    router.default_response_class,
                    default_response_class,

                            }
                          },
                          {
                            "name": "envoy.filters.http.router",
                            "typed_config": {

                            }
                          }
                        ],

## Classe `APIRoute` personalizada em um router

você também pode definir o parametro `route_class` de uma `APIRouter`;

## Custom `APIRoute` class in a router

You can also set the `route_class` parameter of an `APIRouter`:

{* ../../docs_src/custom_request_and_route/tutorial003.py hl[26] *}

        route.proxy.type() == Proxy.Type.DIRECT &&
        route.socketAddress == it.socketAddress
    }
  }

  private fun supportsUrl(url: HttpUrl): Boolean {
    lock.assertHeld()

    val routeUrl = route.address.url

    if (url.port != routeUrl.port) {
      return false // Port mismatch.
    }

    if (url.host == routeUrl.host) {
      return true // Host match. The URL is supported.
