Setup an Azure Runbook with a Webhook URI using Az.Automation CLI
Azure Resource Manager — ARM | Powershell Gallery | Azure Portal | Serverless | Functions
Microsoft inherently generates a Webhook when associating a Runbook to an Action Group. An Action Group is what is used to set up some sort of Action when an Alert is triggered from the metrics of a resource. However, the inherited webhook seems to only be an option within the Azure portal. A Webhook URI is a required parameter because the $Webhook payload is generated from the Alert to the Automation Accounts Runbook.
If you are working with Azure Resource Management (ARM) templates you still are required to create a Webhook and associate that ServiceURI to a Runbook Reciever in an Action Group. However, after the ARM template is provisioned you may still have issues when it comes to updating a Webhook associated with an Action Group. You could technically rerun the ARM template for the Webhook and then rerun the template for the Action Group to update these in a declarative approach. Or…. You can just run a simple Powershell script. :)
