The /websocket endpoint is used to provide real-time interaction with modules running on Engine. It provides an interface to build efficient, responsive user interfaces, monitoring systems and other extensions which require live, two-way or asynchronous interaction.

If you are building browser-based experiences we have a pre-built AngularJS client library ready to go:


Otherwise, if you are working with other frameworks, or would like to build your own, read on.

Opening the Connection

A connection to the real-time API can be established by requesting the /control/websocket endpoint with valid access token. The method for this will vary depending on the tooling used for your app, but as a simple example in JavaScript this can be achieved by creating a new WebSocket object:

let socket = new WebSocket('wss://example.com/control/websocket?bearer_token=<access token>');

When opened, this will provide a full-duplex stream for communications.
