Checkly is an API and E2E monitoring platform. You can use it to configure synthetic and API monitoring as part of your existing infrastructure codebase, cover E2E scenarios using JavaScript, and adapt checks with Node.js-based setup and teardown scripts.

Integrating FireHydrant with Checkly lets you automatically send alert data from Checkly to FireHydrant to declare an incident and kick off a Runbook. This way, you'll see an alert in your configured Slack channel when a check fails.


  • You will need Owner permissions to configure integrations on FireHydrant
  • Ensure you have Slack configured and a default notification channel set in the configuration settings

Validating the integration

It should work immediately once you've configured the alert and subscribed channels to it. If you want to validate, however, you can do the following as a quick test:

  1. On the Checkly home page, you should see a dashboard for your alerts. You can either create a new simple one or click the contextual kebab menu for any existing alert and select Edit check.
  2. From the next page that opens, you can edit your check configuration. Modify the HTTP request URL so that you can "fail" your check (this will help to confirm that you'll receive alerts from Checkly as configured). In the upper-right corner of the page, click Save check.

  1. Go back to your dashboard and click Run now. The dashboard should turn red to indicate the failed check. An alert should pop up in the default alerts channel you configured in Slack.
