How does Unified Push Notification work?  Worklight server will store the device token mapped with the user and the apps.  Support multiple devices per user and multiple apps per device  If device token expires, the worklight server will ask the device to obtain another token from the vendor push service. Worklight Runtime Component Web Code Device APIs YesNo 2. Obtain the Device Token 1. Contact the Vendor Push Service Vendor Push Service (e.g. Apple APN, Google C2DM) Worklight Server 3. Send Token to Worklight Server UserDevice Token Applications ABC23984298 3882993 MyApp CCC3248192MyApp IBMApp MyApp Event Source Adapter IBMApp Event Source Adapter Backend System 1 Backend System 2 5. Poll at an interval for notification update 6. Backend calls the adapter when they want to send notifications 7. Send the notification package with device token to push service 8. Send the notification to device
