Guide: Setting Up Failure Alerts

HookMux can monitor your webhook deliveries and automatically notify you via email when a destination starts failing repeatedly. This allows you to be proactive and fix issues before they impact your users.

This feature is available for Paid Plans users.

How Alerts Work

You can configure an Alert on any Source. The alert monitors all destinations for that source.

You set a Failure Threshold, which is the number of consecutive (in-a-row) failures from a single destination that will trigger a notification.

When a destination fails X times in a row, HookMux will send an email to your specified target. It will continue to send notifications in 2 hours period until the destination successfully receives an event, at which point the failure counter is reset.

How to Set Up an Alert

1. From the dashboard, navigate to the Source you wish to monitor.
2. Click on the Alerts tab (next to "Destinations" tab).
3. Click the Create Alert button.
4. Set the Type: Choose which type of transport do you want the alert to be sent. Currently, only e-mail is available. But in the future, there will be more added.
5. Set the Target: Enter the email address where you want to receive the failure notifications
   (e.g.: dev-alerts@my-app.com).
6. Set the Threshold: Enter the number of consecutive failures that should trigger the alert. A good starting point is 5 or 10. This prevents noisy alerts from a single, random network blip.
7. Click Create.

That's it. Your alert is now active. If any destination associated with that source fails 5 (or your set number) times in a row, HookMux will immediately send an email to your target address with the details of the failing endpoint.
