BlackBerry Spark Communications Services for iOS Documentation

Introduction

The BlackBerry Spark Communications Services provide a framework to develop real-time, end-to-end secure messaging capabilities in your own product or service.

The Spark Communications security model ensures that only the sender and intended recipients can see each message sent, and ensures that messages aren't modified in transit between the sender and recipient. Spark Communications also provides the framework for other forms of collaboration and communication, such as push notifications, secure voice and video calls, and file sharing. You can even extend and create new types of real-time services and use cases by defining your own custom application protocols and data types.
