The only new thing is the `callbacks=invoices_callback_router.routes` as an argument to the *path operation decorator*. We'll see what that is next.

## Documenting the callback

The actual callback code will depend heavily on your own API app.

And it will probably vary a lot from one app to the next.

It could be just one or two lines of code, like:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"

com/MagicStack/uvloop" class="external-link" target="_blank">`uvloop`</a >, le remplaçant hautes performances de `asyncio`.

Mais si vous souhaitez utiliser directement **Trio**, vous pouvez utiliser **Hypercorn** car il le prend en charge. ✨

### Installer Hypercorn avec Trio

Vous devez d'abord installer Hypercorn avec le support Trio :

<div class="termy">

```console
$ pip install "hypercorn[trio]"
---> 100%
```
