<script type="text/javascript">
    appId: applozicApplicationKey,      //Get your application key from
    userId: userId,                     //Logged in user's id, a unique identifier for user
    userName: username,                 //User's display name
    imageLink : '',                     //User's profile picture url
    email : '',                         //optional
    contactNumber: '',                  //optional, pass with internationl code eg: +13109097458
    desktopNotification: true,
    source: '1',                          // optional, WEB(1),DESKTOP_BROWSER(5), MOBILE_BROWSER(6)
    notificationIconLink: '',    //Icon to show in desktop notification, replace with your icon
    authenticationTypeId: 1,          //1 for password verification from Applozic server and 0 for access Token verification from your server
    accessToken: '',                    //optional, leave it blank for testing purpose, read this if you want to add additional security by verifying password from your server
    locShare: true,
    googleApiKey: "AIzaSyDKfWHzu9X7Z2hByeW4RRFJrD9SizOzZt4",   // your project google api key 
    googleMapScriptLoaded : false,   // true if your app already loaded google maps script
    autoTypeSearchEnabled : true,     // set to false if you don't want to allow sending message to user who is not in the contact list
    loadOwnContacts : false, //set to true if you want to populate your own contact list (see Step 4 for reference)
    onInit : function(response) {
       if (response === "success") {
          // login successful, perform your actions if any, for example: load contacts, getting unread message count, etc
       } else {
          // error in user login/register (you can hide chat button or refresh page)
   contactDisplayName: function(otherUserId) {
         //return the display name of the user from your application code based on userId.
         return "";
   contactDisplayImage: function(otherUserId) {
         //return the display image url of the user from your application code based on userId.
         return "";
   onTabClicked: function(response) {
         // write your logic to execute task on tab load
         //   object response =  {
         //    tabId : userId or groupId,
         //    isGroup : 'tab is group or not'
         //  }

It can also be called from any event, for example: on click of a button.

Note :

1) desktopNotification support only for chrome browser, notificationIconLink will be displayed in desktop notification.

2) By Default source is set to WEB(1).

Step 3: Initiate Chat

To initiate chat with another user using userId:

  $applozic.fn.applozic('loadTab', otherUserId);

Alternatively, you can add a chat button inside your web page using a tag and use 'userId' of the other user for data attribute "data-mck-id"

  <a href="#" class="applozic-launcher" data-mck-id="PUT_OTHER_USERID_HERE" data-mck-name="PUT_OTHER_USER_DISPLAY_NAME_HERE">CHAT BUTTON</a>

To open the chat list:

  $applozic.fn.applozic('loadTab', '');

Step 4: Populate contact list

Javascript code to load contacts

// Contacts Array
 var contactsJSON = [{"userId": "USER_1", "displayName": "Devashish",
                          "imageLink": "", // image url (optional)
                          "imageData" :"Base64 encoded image data"  // or image data (optional)
                         {"userId": "USER_2", "displayName": "Adarsh",
                          "imageLink": "", // image url (optional)
                          "imageData" :"Base64 encoded image data"  // or image data (optional)
                         {"userId": "USER_3", "displayName": "Shanki",
                          "imageLink": "",  // image url (optional)
                          "imageData" :"Base64 encoded image data"  // or image data (optional)
 // Function calling inside onInit(from #Step 2) after plugin initialize successfully
    onInit : function(response) {
       if (response === "success") {
          // calling function load contacts
           $applozic.fn.applozic('loadContacts', {"contacts":contactsJSON});
       } else {
          // error in user login/register (you can hide chat button or refresh page)
   //Set loadOwnContacts to true from Step 2
   loadOwnContacts : true,

NOTE- Call loadContacts function only after plugin initialize callback (see Step 2 onInit function for reference).

Step 5: Group Messaging

Group have 2 identifiers: groupId: Auto generated by Applozic clientGroupId (optional): In case if you already have group identifier on your applicaiton side, use clientGroupId in all functions.

Open group chat
 $applozic.fn.applozic('loadGroupTab', groupId);  // group Id returned in response to group create api  

Open group chat using Client Group Id

Create Group
$applozic.fn.applozic('createGroup', {'groupName' : groupName,   // required
                                      'type' : 1,                // 1 for private , 2 for public, 5 for broadcast (required)
                                      'clientGroupId' : '',      // optional
                                      'users': [{ userId:userId1, 
                                                  groupRole : 3  // (optional)  USER(0), ADMIN(1), MODERATOR(2), MEMBER(3)
                                                { userId:userId2,
                                                  groupRole :3  // (optional)  USER(0), ADMIN(1), MODERATOR(2), MEMBER(3)
                                               'callback' : function(response){console.log(response);}}); 

Access level based on role of users in group :-

USER(0),               - Chat
ADMIN(1),              - Full access
MODERATOR(2)           - Add/remove users + Group Info update

                                       'clientGroupId': clientGroupId, //use either groupId or clientGroupId
                                       'userId': userIdToAdd,
                                       'role' :  3,  // (optional)  USER(0), ADMIN(1), MODERATOR(2), MEMBER(3)
                                       'callback': function(response) {console.log(response);}

$applozic.fn.applozic('removeGroupMember',{'groupId': groupId,
                                         'clientGroupId' : clientGroupId, //use either groupId or clientGroupId
                                         'userId': userIdToRemove,         
                                         'callback': function(response) {console.log(response);}

$applozic.fn.applozic('leaveGroup', {'groupId' : groupId,
                                    'clientGroupId' : clientGroupId, //use either groupId or clientGroupId
                                    'callback' :function(response){console.log(response);}
Update Group
$applozic.fn.applozic('updateGroupInfo', {'groupId' : groupId
                                    'clientGroupId' : clientGroupId, //use either groupId or clientGroupId,
                                    'name' : groupName, // optional
                                    'imageUrl' : '',  //optional
                                    'users': [                      // required only if want to update user role
                                               userId:userIdToUpdate, // required
                                               role:3,  // (required)    USER(0), ADMIN(1), MODERATOR(2), MEMBER(3)
                                    'callback' : function(response){console.log(response);}});
Get group list
$applozic.fn.applozic('getGroupList', {'callback':function (response) { //write your logic}});   

Sample response:

           {'status' : 'success' ,                 // or error
            'data': [ {'id': groupId,
                       'name' : groupName',
                       'type' : '2',               // 1,2 or 5   (private, public or broadcast)
                       'memberName':[],           // Array of group member ids
                       'adminName': '',           // Put group admin's userId
                       'removedMembersId' [],     // Array including removed or left members Id  
                       'unreadCount' : '10'       // total unread count of messages for current logged in user

Step 6: Context (Topic) based Chat

Add the following in window.applozic.init call:

 topicBox: true,
 getTopicDetail: function(topicId) {
        //Based on topicId, return the following details from your application
        return {'title': 'topic-title',      // Product title
                    'subtitle': 'sub-title',     // Product subTitle or Product Id
                    'link' :'image-link',        // Product image link
                    'key1':'key1' ,              // Small text anything like Qty (Optional)
                    'value1':'value1',           // Value of key1 ex-10 (number of quantity) Optional
                    'key2': 'key2',              // Small text anything like MRP (product price) (Optional)
                    'value2':'value2'            // Value of key2 ex-$100  (Optional)
