APIs help abstract complexity and allow easy access to data – building innovative apps has never been easier. However, once your user base reaches a critical mass, this can quickly cause performance issues and a miserable user experience. In this session we’ll introduce a concept that is similar to push notifications on your smartphone, we’ll talk about use cases and show you how easy it is to turn existing REST API endpoints into event-driven APIs that save you bandwidth, management cost and, ultimately, allow you to build engaging real-time user interfaces that delight your customers.
