Can you try header like this and check

var ws = new WebSocket('wss://apiv2.unificationengine.com/v2/ws/start', {
    origin: 'https://apiv2.unificationengine.com',
    headers: { Authorization: 'base64 auth' }
});
You can create base64 auth like this in nodejs

var auth = "Basic " + new Buffer(USER_ACCESS_KEY + ":" + USER_ACCESS_SECRET).toString("base64");

resolve it:

var ws = new WebSocket('wss://***.com/v2/ws/start', {
    origin: 'https://***.com',
});
