Refer Managing Assets for managing multiple assets and paths

  1. Check if user is already registered
  1. Else register user
var userID = 1;
            var deviceID = userID + new Date().getTime(); //any random no.
            var deviceProfile = new IMI.ICDeviceProfile(deviceID, userID);
            var registerCallback = {
                onSuccess: (msg) => {
                onFailure: (err) => {
            IMI.IMIconnect.register(deviceProfile, registerCallback);
  1. Connect
    In registration onSuccess callback, add below code:
var messaging = IMI.ICMessaging.getInstance();
    if (!messaging.isConnected())
  1. Register Listener for in-app messaging
var msgCallBack = {
            onConnectionStatusChanged: (statuscode) => {
                console.log('onConnectionStatusChanged to', statuscode);
            onMessageReceived: (message) => {
                console.log('onMessageReceived ', message);
        var messaging = IMI.ICMessaging.getInstance();
  1. Create a thread
createThread(title) {
        var title = title || "New Conversation";
        var thread = new IMI.ICThread();
        var messaging = IMI.ICMessaging.getInstance();
        messaging.createThread(thread, createThreadCallBack);
    createThreadCallBack = {
        onSuccess: (threadObj) => {
        onFailure: (err) => {

  1. Publish a message
var publishMessageCallback = {
  onSuccess: function (msg) {
    console.log("message sent", msg);
  onFailure: function (errormsg) {
    console.log("failed to send message", errormsg);
function publish() {
  var text = "Sample message text";
  var message = new IMI.ICMessage();
  var messaging = IMI.ICMessaging.getInstance();
  messaging.publishMessage(message, publishMessageCallback);
