Prerequisites

• Use the following parameters to specify the API endpoint in the request URL:

  • ${SUBSCRIPTION_ID}
  • ${USERGROUP_ID}
  • ${VM_SCALE_SET_ID}

  Use the following example to help locate values in Azure:
  
  

• Configure OAuth 2.0 Azure credentials with the following values:

  • Scope: https://management.azure.com/.default
  • Access Token URL: https://login.microsoftonline.com/{TENANTID}/oauth2/v2.0/token
    
    

  Although "(optional)" appears next to the Scope field in the UI, this value is required for API pollers based on this template.
  

• The Virtual Machine Scale Set has access control to the Application with at least the Reader role.
