Se seu arquivo for nomeado `main.py`, execute sua aplicação com:

<div class="termy">

Dies kann es Ihren Benutzern viel einfacher machen, **deren APIs zu implementieren**, um Ihre **Webhook**-Requests zu empfangen. Möglicherweise können diese sogar einen Teil ihres eigenen API-Codes automatisch generieren.

/// info | Info

Webhooks sind in OpenAPI 3.1.0 und höher verfügbar und werden von FastAPI `0.99.0` und höher unterstützt.

///

## Eine App mit Webhooks { #an-app-with-webhooks }

	timeout 15m /tmp/mc ready myminio || fail

	# Wait for all drives to be online and formatted
	while [ $(/tmp/mc admin info --json myminio | jq '.info.servers[].drives[].state | select(. != "ok")' | wc -l) -gt 0 ]; do sleep 1; done
	# Wait for all drives to be healed
	while [ $(/tmp/mc admin info --json myminio | jq '.info.servers[].drives[].healing | select(. != null) | select(. == true)' | wc -l) -gt 0 ]; do sleep 1; done

Например, вы можете использовать это, чтобы добавить метаданные для фронтенд‑пользовательского интерфейса и т.д.
