Sparkcentral Messenger SDK 1.25.7

The Sparkcentral Messenger SDK enables you to implement a customizable, fully-featured messenger on your website or inside your mobile app. This allows any customer who visits your website or uses your app to contact your support team directly, eliminating the need for your users to use Facebook, WhatsApp, or any other messaging platform. 

Implementing Messenger on your website

Latest version

The latest version of our Web Messenger SDK can be found here:

Get started

Create a channel

  1. On the Settings tab, expand Channels & Business Hours and select Channels.
  2. Select Add Channel, and then select Sparkcentral Messenger.
  3. In the window that appears, enter a name for your messenger channel. This name should be unique and specific to the location of your messenger, such as a specific web page or your mobile app. Select Next.
    Note: If the window doesn't appear, make sure your browser allows pop-ups from Sparkcentral.
  4. Save the information provided in the window that appears. This information will only be displayed once, so it’s important to record it now.

Implement the Web Messenger on your website

The following steps are required to get the Web Messenger to appear on your website.

At the end of your <head> tag, paste the following code. (Make sure to copy it all).


var loaderUrl = ''

!function(e,n,t,r){function s(){try{var e;if((e="string"==typeof this.response?JSON.parse(this.response):this.response).url){var t=n.getElementsByTagName("script")[0],r=n.createElement("script");r.async=!0,r.src=e.url,t.parentNode.insertBefore(r,t)}}catch(e){}}var o,p,a,c=[],i=[];e[t]={init:function(){o=arguments;var e={then:function(n){return i.push({type:"t",next:n}),e},catch:function(n){return i.push({type:"c",next:n}),e}};return e},on:function(){c.push(arguments)},render:function(){p=arguments},destroy:function(){a=arguments}},e.__onWebMessengerHostReady__=function(n){if(delete e.__onWebMessengerHostReady__,e[t]=n,o)for(var r=n.init.apply(n,o),s=0;s<i.length;s++){var u=i[s];r="t"===u.type?r.then(}p&&n.render.apply(n,p),a&&n.destroy.apply(n,a);for(s=0;s<c.length;s++)n.on.apply(n,c[s])};var u=new XMLHttpRequest;u.addEventListener("load",s),"GET",loaderUrl,!0),u.responseType="json",u.send()}(window,document,"Sparkcentral");


Paste the init call code below toward the end of the <body> section to initialize Messenger without any special customizations. On the third line, insert your specific channel App ID. This is one of the pieces of text that is generated on channel creation.

//TODO Sparkcentral APP_ID, replace this with your own to run this demo.
var appId = 'YOUR APP ID HERE';
//function to initialise Sparkcentral, this will also register all our events we want to listen on.
//this function will be called when the document finishes loading. (event in the end of this script tag)
function initialiseSparkcentral() {
//Display a message that there are unread messages
Sparkcentral.on('unreadCount', function(unreadCount) {
//create a message based on the unread messages count
var message = 'There are ' + unreadCount + ' unread messages.';
if(unreadCount == 1) {
message = 'There is one unread message.';
//Initialise Sparkcentral,
//Add your custom options here
appId: appId,
businessName: 'Your business name here',
customText: {
headerText: 'Your header text here',
inputPlaceholder: 'Your input-placeholder here',
introductionText: 'Your introduction text here',
messageSending: 'Sending...',
messageDelivered: 'Delivered',
sendButtonText: 'Send',
customColors: {
brandColor: '000000',
conversationColor: '4690DC',
actionColor: '4690DC',
menuItems: {
imageUpload: 'true',
}).then(function() {
//when our document is finished loading, we'll initialisze our sparkcentral instance.
window.addEventListener('load', function() {

Customize your Web Messenger options

Several options are available for customizing your Web Messenger. The following is an example of a fully customized Web Messenger. Every option used is documented following the code snippet.

Adjust your region

The region field must be set according to your Sparkcentral instance. In the following initialization code, there is a field called region: 'eu-1'. This initializes the European version of the messenger. To access the United States messenger, leave the field unspecified.

Use shortcodes to create a rich messaging experience

Shortcodes are a useful way to create a beautiful messaging interface.

Available shortcodes

Table of shortcodes
Element Syntax Example
Link button %[]() %[Button label](
Reply button %[](reply:) %[Button label](reply:PAYLOAD)
Location request button %[](location) %[Button label](location)
Image ![]() ![](http://url-of.the/image.jpg)

Link button

By using multiple Link button shortcodes, you can send the user multiple links in one message. An example:

%[Link to Facebook](

%[Link to Twitter](

%[Link to LinkedIn](


Reply button

By using multiple Reply button short codes under each other in one message, you can offer the user a choice. For example:





Location sharing button

This code allows you to ‘invite’ the user to share their location with you.



You can send images and gifs using this shortcode.


Implement Messenger in your mobile app

A great way to integrate Sparkcentral into your processes is by incorporating our In-App Messenger. This is an SDK we created that our clients can implement on their apps.

Available platforms

  • iOS
  • Android

Getting started


To use our SDK with your iOS application, you will need to add it to your Xcode project.

Installing the SDK dependency

The first thing to do is install CocoaPods. CocoaPods is a dependency manager for Swift and Objective C Cocoa projects.

To install it, run the following command in your terminal.

gem install cocoapods

Next, ell Xcode you will be using this pod/dependancy. To do so, create a file called “podfile” in the source folder of your project. In it, enter the following and save it:

project 'Location of your .xcproj file'
target 'YourApp' do
pod 'Sparkcentral'

Now run a command to tell Xcode to install the pod so you can use it. In your terminal, navigate to the source folder of your project. Type the following command in the terminal:

pod install

Navigate to your source folder and open Info.plist file. In it, add the following keys and values and save it.

<string>${PRODUCT_NAME} will read your photo library to gather additional information</string>
<string>${PRODUCT_NAME} will write to your photo library to gather additional information</string>
<string>${PRODUCT_NAME} will use your camera to gather additional information</string>

Use the framework in your project

Objective C

Import the framework in your source code.

#import "Sparkcentral/Sparkentral.h"

The first function to run is the following. Your app ID should be change accordingly.

[Sparkcentral initWithSettings:[SKCSettings settingsWithAppId:@"YOUR_APP_ID"] completionHandler:^(NSError * _Nullable error, NSDictionary * _Nullable userInfo) {
// Your code after init is complete


Sparkcentral.initWith(SKCSettings(appId: "YOUR_APP_ID")) { (error: Error?, userInfo: [AnyHashable : Any]?) in
// Your code after init is complete

Class reference

The entire class reference can be found here:


Link the SDK dependency

Include the following code in your Gradle file:

repositories {
maven {
url ""
dependencies {
compile 'com.sparkcentral:core:latest.release'
compile 'com.sparkcentral:ui:latest.release'

Using the SDK

Initialize from your Application class. Add the following lines of code to your onCreate method on your Application class:

Sparkcentral.init(this, new Settings("YOUR_APP_ID"), new SparkcentralCallback() {
public void run(Response response) {
// Your code after init is complete

Make sure to replace YOUR_APP_ID with the app ID you generate when adding a new Web Messenger channel.

If you don’t have an Application class, you must create one to make sure Sparkcentral is always initialized properly.
