### Add the callback router { #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:

In OkHttp some fields of the address come from the URL (scheme, hostname, port) and the rest come from the [OkHttpClient](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-ok-http-client/).

### [Routes](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-route/)

O parâmetro `summary` está disponível no OpenAPI 3.1.0 e superior, suportado pelo FastAPI 0.99.0 e superior.

Perceba que você não está passando o roteador em si (`invoices_callback_router`) para `callback=`, mas o atributo `.routes`, como em `invoices_callback_router.routes`.
