Sparkcentral Messenger SDK

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. 

Create your 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.
    Note: This information is only displayed once, so it’s important to record it now.

Implement Messenger on your website

Latest version

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

The previous version can be found here: Sparkcentral Messenger SDK 1.25.7

Get started

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

  1. Paste the following code the end of the <head> section. (Make sure to copy it all!)


    !function(s,c,o,i){var a,p,u,d=[],f=[];function e(){var n="2.1.0";try{if(!i)throw new Error(n);var e,t="",r="sparkcentral";if((e="string"==typeof this.response?JSON.parse(this.response):this.response).url){var s=c.getElementsByTagName("script")[0],o=c.createElement("script");o.async=!0;var a=i.match(/([0-9]+)\.?([0-9]+)?\.?([0-9]+)?/),p=a&&a[1];if(a&&a[3])o.src=t+r+"."+i+".min.js";else{if(!(1<=p&&e["v"+p]))throw new Error(n);o.src=e["v"+p]}s.parentNode.insertBefore(o,s)}}catch(e){e.message===n&&console.error(e)}}s[o]={init:function(){a=arguments;var n={then:function(e){return f.push({type:"t",next:e}),n},catch:function(e){return f.push({type:"c",next:e}),n}};return n},on:function(){d.push(arguments)},render:function(){p=arguments},destroy:function(){u=arguments}},s.__onWebMessengerHostReady__=function(e){if(delete s.__onWebMessengerHostReady__,s[o]=e,a)for(var n=e.init.apply(e,a),t=0;t<f.length;t++){var r=f[t];n="t"===r.type?n.then(}p&&e.render.apply(e,p),u&&e.destroy.apply(e,u);for(t=0;t<d.length;t++)e.on.apply(e,d[t])};var n=new XMLHttpRequest;n.addEventListener("load",e),"GET","",!0),n.responseType="json",n.send()}(window,document,"Sparkcentral","2");


  2. Paste the init call code below toward the end of the <body> section. This initializes a basic Web Messenger without any special customizations. (Optional customizations are described in the next section.)
    • On the third line, insert your specific channel Integration ID. This is one of the pieces of text that is generated on channel creation.
    • The region field must be set according to your Sparkcentral instance. Sparkcentral is available in the following regions:
      Region Region identifier
      United States Leave unspecified
      European Union eu-1

Customize 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.


The following general settings can be changed.

Prechat capture option

This option allows you to have the Web Messenger automatically post a message to the user. You can implement a variety of messages. The following code snippet is the same as the one used in the earlier example.

prechatCapture: {
enabled: true,
fields: [
type: 'email',
name: 'email',
label: 'Email',
placeholder: ''
type: 'text',
name: 'company-website',
label: 'Company website',
placeholder: ''
type: 'select',
name: 'company-size',
label: 'Company size',
placeholder: 'Choose a number...',
options: [
name: '1-10',
label: '1-10 employees'
name: '11-50',
label: '11-50 employees'
name: '51+',
label: '51+ employees'
Field Information

name: ‘Name of the field’,
label: ‘Label name’,
placeholder: ‘Placeholder text here'”

Text name: ‘Name of the field’,
label: ‘Label name’,
placeholder: ‘Placeholder text here'”

This is the format in which multiple options are added:

options: [ { name: ‘Name of the first option’,
label: ‘Label of the first option’
name: ‘Name of the second option’,
label: ‘Label of the second option’
name: ‘Name of the third option’,
label: ‘Label of the third option’

Embedded mode option

You have the option to set up the Web Messenger in an embedded mode. This lets you choose where you want the widget to be visible.

The following example illustrates what you need to set it up.

Note that for embedded mode to work, you must set the parameter of embedded to true and call the Sparkcentral.render() function manually.

integrationId: 'INTEGRATION_ID_HERE',
embedded: true,
region: 'eu-1'
}).then(() => {
// Your code after init is complete

This sample embeds the Sparkcentral messenger within a DOM element with the id “chat-container”. If you open the web page, you will notice that it is no longer showing a button on the bottom right, but it is visible in the container element.

Use Contact Attributes to save specific messenger data

You can store information about the webpage and the user by using the Contact Attributes feature. To enable this, do the following:

  1. On the Settings tab, expand Agent Workspace and select Contact Attributes.
  2. Find one of the premade Contact Attributes in the list and toggle it to Enabled.

Now, when a client contacts you via the Sparkcentral Messenger plugin, that specific data will be stored inside of a Contact Attribute.

Available Contact Attributes for the Web Messenger plugin

  • Browser Language
  • First Name
  • Last Name
  • Page Domain
  • Page Title
  • Page URL
  • User Id

Use shortcodes to create a rich messaging experience

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

Available 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 shortcodes 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

Get started


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

Install the SDK dependency

First, 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, tell Xcode you are 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 changed 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

Download the class references for iOS and Android:


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'

Use 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.
