  1. Introduction to BlackBerry Push API Pratik Sapra, Mobile Application Development Specialist

  2. Introduction To BlackBerry Push API • Overview • Architecture • Security • Requesting Access

  3. Overview – BlackBerry Push API • Provides a transport infrastructure for Server to Device pushed data • Primary focus on consumer applications • Alerts • Replace polling to improve performance & reduce costs • Poke-Pull model • Event driven systems • Near real-time notifications Can be used for enterprise deployments • Cross company applications • Enterprises without a BlackBerry Enterprise Server

  4. Overview – Benefits • Provides information immediately • Optimizes network efficiency • Preserves the battery life • Reduces complexity for developers • Improves developer margins

  5. Architecture • Pushes are initiated on the Server • Server side application is required • Server to Server interface for the Push Initiator • BlackBerry Infrastructure is the middleware • Sends data to a specified port on the Device • Client side Java application required to receive the push • Uses PAP 2.2 Standard push protocols • OMA-WAP-TS-PAP-V2_2-20071002-C • Requests are HTTP XML requests • Supported requests: • Submit Push • Cancel Push • Query for Status • Response: • Result notification

  6. Architecture – Components Three major components: • The server-side push service • A client-side application • BlackBerry Infrastructure

  7. Architecture – Push Request Workflow • Server sends PAP Push which contains a list of specified devices • BlackBerry Infrastructure sends response to Server and queues request • BlackBerry Infrastructure pushes data to specified devices • Each device sends ACK to BlackBerry Infrastructure • BlackBerry Infrastructure sends notification to Server • Server sends Read notification to BlackBerry Infrastructure 1 Push Request 3 Response Push 2 Mobile Client Push Initiator BlackBerry Infrastructure 4 5 Acknowledgement Result Notification Response 6

  8. Security • BlackBerry Infrastructure Authentication • Push Initiator is authenticated to the BlackBerry Infrastructure • Push Initiator can only push to its mobile application • 1:1 relationship between Push Initiator and mobile application • Push Initiator can only push to devices registered for their application • Each push request is authenticated to BlackBerry Infrastructure • Unique listening port for each application • BlackBerry Infrastructure does not encrypt data • Expects that payload data will already be encrypted by Push Initiator • Content Provider Authentication • Mobile application should be authenticated to the Push Initiator

  9. Requesting Access • Register at www.blackberry.com/pushapi • Sample code provided on registration approval • Content Provider tests the push service • Given access to the evaluation infrastructure • Research In Motion validates the Content Provider’s client and server-side applications • Ensuring development guidelines are met • Service is moved into production • Once all requirements are met • Only available to ISV Alliance Partners • To become an ISV Alliance partner visit www.blackberry.com/allianceapplication • Contact for service costs
