+## Incoming Scalr Webhook
+[Guide by @hassanbabaie]
+Scalr makes webhook calls based on an event to a configured webhook endpoint (for example Host Down, Host Up). Webhook endpoints are URLs where Scalr will deliver Webhook notifications.  
+Scalr assigns a unique signing key for every configured webhook endpoint.
+Refer to this URL for information on how to setup the webhook call on the Scalr side: [Scalr Wiki Webhooks](https://scalr-wiki.atlassian.net/wiki/spaces/docs/pages/6193173/Webhooks)
+In order to leverage the Signing Key for addtional authentication/security you must configure the trigger rule with a match type of "scalr-signature".

+### 5. Match scalr-signature
+
+The trigger rule checks the scalr signature and also checks that the request was signed less than 5 minutes before it was received. 
+A unqiue signing key is generated for each webhook endpoint URL you register in Scalr.
+Given the time check make sure that NTP is enabled on both your Scalr and webhook server to prevent any issues
