Create a webhook notifier

To configure a webhook notifier, enter a URL that specifies the endpoint to send HTTP POST requests to. You can use variables in your notifiers.

To create a webhook notifier:

  1. In the navigation menu select Alerts> Notifiers.

  2. Click Create notifier.

  3. Enter a descriptive name for the notifier.

  4. Select Webhook as the type of notifier you want to create.

  5. In the URL field, enter a URL, which is called as a POST request. For example:

    https://webhook.site/3723e8cb-b1b4-4399-86b0-e37f36a2acc5

  6. Optional: Select Notify when resolved to send a resolved alert notification.

  7. Click Save.

Webhook notifier request body

The following example outlines the body for a POST request to a webhook. The request consists of one triggered alert called "test alert" that has several associated labels, such as component, instance, and job.

This example contains several notable sections:

  • commonLabels: Contains labels that are common across all alerts in a notification display. Each alerting series includes the full list of labels. Any static labels that you define also display under commonLabels.
  • groupLabels: Contains label values for the related signal display, in addition to a "severity" for the label.
  • fingerprint: A representation of an alerting series, expressed as a deterministic value based on the hash of the labels.
