Webhooks are HTTP callbacks. Webhooks allows you to receive actions that happen in your AlertAgility account. This is a great way to receive all actions like a triggered alarm, an acknowledgement, or a resolved incident into a user application from AlertAgility so you can do further processing and action on these event outside of AlertAgility.
Currently, webhooks are supported in various forms. You can create multiple webhooks for each integration service you configure. Any action that happens for the service is automatically pushed to your webhook url.
Similary, integration with third party applications like Slack and HipChat works though webhooks.
See, integration with Slack or HipChat for example.
