Azure Notification Hubs provide an easy-to-use infrastructure that enables you to send mobile push notifications from any backend (in the cloud or on-premises) to any mobile platform.
Configuration steps include:
1 . Configure your Notification Hub
2 . Connecting your app to the Notification Hub
3 . Send notification from your back-end
You can send notifications using Notification Hubs from any back-end using the REST interface. You do this through a script, not a configuration of Mobile Services. Use Java or
PHP for the script.
