Splunk® Enterprise

Alerting Manual

Use a webhook alert action

Webhooks allow you to define custom callbacks on a particular web resource. For instance, you can set up a webhook to make an alert message pop up in a chat room or post a notification on a web page. When an alert triggers, the webhook makes an HTTP POST request on the URL. The webhook passes JSON formatted information about the alert in the body of the POST request.

When you set up a webhook alert, you must get the hook URL from the target source. For example, if you want to post a webhook alert to a Slack room, you must follow Slack's webhook instructions to get the correct URL to use. You can test that webhooks are triggering by using a webhooks testing site such as https://webhook.site.

In Splunk Enterprise version 9.0 and higher, before a triggered alert can send a request to a specified URL, you must add the URL to the webhook allow list. For more information, see Configure webhook allow list.

Webhook data payload

The webhook POST request's JSON data payload includes the following details.

  • Search ID or SID for the saved search that triggered the alert
  • Link to search results
  • Search owner and app
  • First result row from the triggering search results



	"result": {
		"sourcetype" : "mongod",
		"count" : "8"
	"sid" : "scheduler_admin_search_W2_at_14232356_132",
	"results_link" : "http://web.example.local:8000/app/search/@go?sid=scheduler_admin_search_W2_at_14232356_132",
	"search_name" : null,
	"owner" : "admin",
	"app" : "search"

Depending on the webhook scenario, you can configure data payload handling on the resource receiving the POST.
