# Events

Webhook events notify you when authentication, user account, or authenticator-related changes occur. When an event is triggered, IDaaS sends an HTTP POST request to your configured webhook URL with a JSON payload that describes the event.

Use this page to review the full list of supported webhook events and jump directly to the event-specific documentation for each one.

IDaaS currently supports 16 webhook event types across eight categories.
