Michael,
Unfortunately there is no ready-made script. This is custom logic and its implementation is involved by the user. You may do this without the server code. On the event success for create_service, you should call service to send customer's push using this api: http://devcenter.appery.io/documentat...
And send push on the right device or group of devices. You should handle this push to the event Push notification and call the correct code to update.
