Receive Alert Notifications via Webhook

Getting started

The Webhook channel sends alert notifications as JSON to any HTTP endpoint you configure. Use it to forward alerts to custom services, automation, or tools Last9 does not integrate with natively.

For several popular platforms, Last9 auto-detects the webhook URL and formats the payload for that platform instead of sending the generic payload below. See the dedicated guides for Microsoft Teams, Flock, Google Chat, Telegram, Jira, and Zenduty.

Setting up a notification channel in Last9

1. In Notification Channels, click Add Channel and choose Webhook.
2. Enter the webhook URL of your endpoint.
3. Save the channel. Assign it to an Alert Group to start receiving notifications.

The generic webhook payload uses the following fields.

Field	Type	Description
routing_key	string	The full generic webhook URL generated in Last9. This is used to send alerts to your configured endpoint
