3. In the left-side navigation pane, choose Alert Management > Contact.

4. On the Contact tab, click Create Webhook in the upper-right corner.

Step 3: Link the webhook contact to a notification policy

Associate the webhook contact with a notification policy so that alerts are delivered through the webhook.

1. In the left-side navigation pane, choose Alert Management > Notification Policies.

2. Create or modify a notification policy.

3. On the Notification Objects tab, set Contacts to the webhook contact created in Step 2.

4. Set Notification Methods to Webhook.
