This template demonstrates how to communicate UE4 app to Player Page and back while using Eagle Streaming System.

The Pixel Streaming Plugin that runs within the Unreal Engine exposes a Blueprint API that you can use in your gameplay logic to handle custom UI events sent by the player HTML page and to emit events from the Unreal Engine to the player page.
