Webhook
Webhook is a delivery channel for DAM Alerting: when a rule fires, ALTR sends a JSON payload to your endpoint over HTTP POST.
The webhook URL you supply is stored as a secret field. Connect a webhook from the notification integrations grid, the same as any other provider; see Notification Integrations for how to add, edit, test, and delete a connection. Set up the receiving endpoint on your own infrastructure or with whatever provider hosts it — ALTR does not require anything beyond a reachable URL.
Custom webhook destinations are validated against internal and metadata-service address ranges, both when you save the connection and again at send time, to block requests to internal infrastructure.
