Das `app.webhooks`-Objekt ist eigentlich nur ein `APIRouter`, derselbe Typ, den Sie verwenden würden, wenn Sie Ihre App mit mehreren Dateien strukturieren.

Beachten Sie, dass Sie bei Webhooks tatsächlich keinen *Pfad* (wie `/items/`) deklarieren, der Text, den Sie dort übergeben, ist lediglich eine **Kennzeichnung** des Webhooks (der Name des Events). Zum Beispiel ist in `@app.webhooks.post("new-subscription")` der Webhook-Name `new-subscription`.
