  • ${USERGROUP_ID}: A resource group ID
  • ${APP_NAME}: The App Service name

• 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 App Service has access control to the Application with at least the Reader role.
