# Webhook from Altegio About Application Events

Note: This is not a callable endpoint.

This section describes how Altegio sends webhook notifications when specific events occur in the application-to-location lifecycle. The following event types are currently supported:

* uninstall — Sent when the application is disabled on the Altegio side.

You can configure the webhook URL for receiving these events in your Altegio Developer Account.
