Configure webhook notifications
Use the webhook integration in contact points to send alert notifications to your webhook.
The webhook integration is a flexible way to integrate alerts into your system. When a notification is triggered, it sends a JSON request with alert details and additional data to the webhook endpoint.
Configure webhook for a contact point
To create a contact point with webhook integration, complete the following steps.
- Navigate to Alerts & IRM -> Alerting -> Contact points.
- Click + Add contact point.
- Enter a name for the contact point.
- From the Integration list, select Webhook.
- In the URL field, copy in your Webhook URL.
- (Optional) Configure additional settings.
- Click Save contact point.
For more details on contact points, including how to test them and enable notifications, refer to Configure contact points.

Note
You can customize the
title

options to include custom messages and notification data using notification templates. These fields are always sent as strings in the JSON payload.However, you cannot customize the webhook data structure, such as adding or changing other JSON fields and HTTP headers, or sending data in a different format like XML.
If you need to format these fields as JSON or modify other webhook request options, consider sending webhook notifications to a proxy server that adjusts the webhook request before forwarding it to the final destination.
