Usage
Script
Add the following code towards the end of the head
section on your page.
<script async="true">
!function(s,e,a){var c,o,i,p=[],u=[];s[a]={init:function(){c=arguments;var t={then:function(e){return u.push({type:"t",next:e}),t},catch:function(e){return u.push({type:"c",next:e}),t}};return t},on:function(){p.push(arguments)},render:function(){o=arguments},destroy:function(){i=arguments}},s.__onWebMessengerHostReady__=function(e){if(delete s.__onWebMessengerHostReady__,s[a]=e,c)for(var t=e.init.apply(e,c),n=0;n<u.length;n++)var r=u[n],t="t"===r.type?t.then(r.next):t.catch(r.next);o&&e.render.apply(e,o),i&&e.destroy.apply(e,i);for(n=0;n<p.length;n++)e.on.apply(e,p[n])};var t="2.3.6-ruby-4",n=e.getElementsByTagName("script")[0],e=e.createElement("script");e.async=!0,e.src="https://assets.au.stackchat.com/sdk/web-messenger/"+t+"/stackchat."+t+".min.js",n.parentNode.insertBefore(e,n)}(window,document,"stackchat");
</script>
And then, initialise the Web Messenger by placing the following code towards the end of the body
section of your page:
<script>
stackchat
.init({
appId: "<app-id>"
})
.then(function () {
// YOUR CODE AFTER INIT IS COMPLETE
});
</script>
Note for users in China If you are using the Stackchat Web Messenger on a Chinese website, then you will need to replace the loader URL in the above script. Please replace
https://assets.au.stackchat.com
with our China CDN:https://assets.common.stackchat.com.cn
. You will also need to add aregion: "cn"
key/value to your config (along with your app id) that you pass in theinit
method.
NPM
- Install via
npm
or a package manager of choice:
npm install --save @stackchat/web-messenger
- Import the module & initialise messenger
import Stackchat from "@stackchat/web-messenger";
Stackchat.init({ appId: "<app-id>" }).then(function () {
// YOUR CODE AFTER INIT IS COMPLETE
});

Voice Support
Stackchat Web Messenger supports speech recognition where available. This is essentially limited to browsers that have implemented the W3C Media Stream API and where access to a recording instrumentation on a device is available. For this reason, if you are using speech recognition, please be aware that there may be compatibility issues with older browsers.

voice
The web-messenger will support Speech Recognition if the service has been made available to the user, to enable it there is a voice configuration object that can be passed in by the user to the init method.
Option | Optional? | Default value | Description |
---|---|---|---|
voiceOnly | Yes | false |
Disables the text input and replaces it with a push to talk button |
voiceOnlyFallback* | Yes | text |
If voice only is set to true and the client device does not support voice then this option will handle what to do for those unsupported devices, options are text , destroy or a function that returns either of those values |
locale | Yes | en_us | Set the voice support language, must conform to BCP-47 |
-
voiceOnlyFallback
- The two options for fallback aretext
ordestroy
, thetext
fallback will revert the application to a basic keyboard based input, whiledestroy
will fail the initialization of the app and prevent the widget from being instantiated, this option is for users that only want to support voice and display nothing in all other instances.
open()
Opens the conversation widget (no-op when embedded)
stackchat.open();
close()
Closes the conversation widget (no-op when embedded)
stackchat.close();
isOpened()
Tells if the widget is currently opened or closed.
stackchat.isOpened();
destroy()
Destroys the Web Messenger and makes it disappear. The Web Messenger has to be reinitialized with init
to be working again because it also clears up the app id from the Web Messenger. It will also unbind all listeners you might have with stackchat.on
.
stackchat.destroy();
sendMessage(message)
Sends a message on the user's behalf
stackchat.sendMessage({
type: "text",
text: "hello"
});
// OR
stackchat.sendMessage("hello");
getConversation()
Returns the conversation if it exists
var conversation = stackchat.getConversation();
getUser()
Returns a user if the conversation has begun and a user has been created, otherwise returns undefined
var user = stackchat.getUser();
if (user) {
// Do something with user data.
}
startConversation()
Creates a user and conversation on the server, allowing the business to reach out proactively to the user via the public API.
It is strongly recommended to only call this method in the case where a message is likely to be sent.
This method is called automatically when starting a conversation via the sendMessage
method, or when a user sends a message via the conversation view.
If a conversation already exists for the current user, this call is a no-op.
stackchat.startConversation();
setPredefinedMessage(message)
Prefills the user's chat input with a predefined message.
stackchat.setPredefinedMessage(message);
simulateMessage(message, ?avatar)
Simulates a message to the client without ever sending one to the server, these messages will not be persisted between sessions.
Takes in an optional second parameter for displaying an avatar associated with the message, this will default to gravatar's empty gray user icon if left blank.
stackchat.simulateMessage(message);
simulateMessage(messageObject, ?avatar)
Simulates a message which has specified predefined reply options.
stackchat.simulateMessage({
message: "Would you like an ice cream?",
actions: ["Yes", "No"]
});
triggerCloudFunction(handler, payload, ?metadata)
Manually invoke a Stackchat cloud function on the users behalf.
stackchat
.triggerCloudFunction("populateSlots", getUserPayload(), {})
.then(() => {
console.log("cloud function invoked");
});
showActivityIndicator(?avatar)
Simulates the behaviour of the bot typing. Shows up as flickering three dots in a message bubble.
hideActivityIndicator()
Removes the typing indicator from the conversation so that the conversation may proceed.
openSpeechRecognitionModal()
Opens up the user speech recognition prompt and begins listening for a user command, this can't be called before the messenger client has finished it's initialisation.
stackchat.init({...}).then(() => {
document.getElementById("open-modal").addEventListener("click", () => {
stackchat.openSpeechRecognitionModal();
});
})
closeSpeechRecognitionModal()
Closes the modal and aborts the current recognition event
stackchat.closeSpeechRecognitionModal();
setDelegate(delegate)
See the section on Delegates below
updateAnalyticsId
By default, a user's unique Stackchat ID will be used when your chatbot sends server-side requests to your configured analytics integrations. However, you may want to override this behaviour so that Stackchat uses a different ID, such as the visitor ID that your website has assigned to the user. This is helpful to get a single view of user behaviour across both website and chatbot.
Adobe Analytics
If you've configured Adobe Analytics report suite for your Stackchat bot, then you can call updateAnalyticsId
method with the below parameter in order to override the visitor ID that your chatbot uses when making server-side requests to Adobe Analytics. If you have server-side forwarding to Adobe Audience Manager configured, then you need to include the regionId
, otherwise it is not required
stackchat.updateAnalyticsId({
adobeAnalytics: {
experienceCloudVisitorId: "ENTER_YOUR_VISITOR_ID_HERE",
regionId: "ENTER_YOUR_REGION_ID_HERE"
}
});
- Populate
experienceCloudVisitorId
property with a value fetched from getMarketingCloudVisitorId - Populate
regionId
property with a value fetched from getLocationHint - Note: One API call is made to Adobe Analytics for every message received from the user.
hasConversationStarted()
Returns a boolean that when true indicates the a user has previously started a conversation and false when they have not, this is useful for those times when you might want to execute some behaviours depending on whether a user has or has not interacted with the widget yet.
const hasStarted = stackchat.hasConversationStarted();
if (hasStarted) {
// Conversation started, do something...
} else {
// Converstaion not yet started, do something...
}
Delegates
Stackchat Web Messenger allows you to set a delegate to receive callbacks when important changes happen in the conversation. To set a delegate, use the following setDelagate
method:
stackchat.setDelegate(delegate);
Delegates should be set after stackchat.init
has been called, like so:
stackchat.init({ appId: '<app-id>' })
.then(
() => {
stackchat.setDelegate(...)
}
)
You can use the one or more of the following delegates:
beforeDisplay
The beforeDisplay
delegate allows a message to be hidden or modified before it is displayed in the conversation. This delegate should return a falsy value such as null
to hide the message. It can also return a modified message object in order to change what the user will see rendered in their conversation history. Note that this change affects the client side rendering only; the server side copy of this message can not be modified by this delegate.
stackchat.setDelegate({
beforeDisplay(message) {
if (message.metadata && message.metadata.isHidden) {
return null;
}
return message;
}
});
beforeSend
The beforeSend
delegate method allows you to modify properties of a message before sending it to stackchat. The modified message must be returned for it to take effect.
stackchat.setDelegate({
beforeSend(message) {
// YOUR CODE HERE
return modifiedMessage;
}
});
beforePostbackSend
The beforePostbackSend
delegate method allows you to modify properties of a postback before sending it to stackchat. The modified postback must be returned for it to take effect.
stackchat.setDelegate({
beforePostbackSend(postback) {
postback.metadata = {
any: "info"
};
return postback;
}
});
beforeWebviewDisplay
stackchat.setDelegate({
beforeWebviewDisplay(url, message, event) {
console.log(url);
return false; // to cancel action
// return; // to allow original behavior, e.g. a no-op
// return 'http://go.here.instead.com?utm=webviewIntercept' // to replace the URL
}
});
The metadata
parameter has the following structure:
metadata = {
event // The click event from the browser
};
Events
To bind an event, use stackchat.on(<event name>, <handler>);
. To unbind events, you can either call stackchat.off(<event name>, handler)
to remove one specific handler, call stackchat.off(<event name>)
to remove all handlers for an event, or call stackchat.off()
to unbind all handlers.
Note: If you want to make sure your events are triggered, try to bind them before calling stackchat.init
, like so:
stackchat.on('<event-1>', function() { ... });
stackchat.on('<event-2>', function() { ... });
stackchat.on('<event-3>', function() { ... });
stackchat.init(...).then(function() {
// Your code after init is complete
});
ready
This event triggers when init completes successfully
stackchat.on("ready", function () {
console.log("the init has completed!");
});
destroy
This event triggers when the widget is destroyed.
stackchat.on("destroy", function () {
console.log("The widget is destroyed!");
});
This is triggered in response to stackchat.destroy()
message:received
This event triggers when the user receives a message
stackchat.on("message:received", function (message) {
console.log("The user received a message", message);
});
message:sent
This event triggers when the user sends a message
stackchat.on("message:sent", function (message) {
console.log("The user sent a message", message);
});
message
This event triggers when a message was added to the conversation
stackchat.on("message", function (message) {
console.log("A message was added to the conversation", message);
});
unreadCount
This event triggers when the number of unread messages changes
stackchat.on("unreadCount", function (unreadCount) {
console.log("The number of unread messages was updated", unreadCount);
});
widget:opened
This event triggers when the widget is opened
stackchat.on("widget:opened", function () {
console.log("Widget is opened!");
});
widget:closed
This event triggers when the widget is closed
stackchat.on("widget:closed", function () {
console.log("Widget is closed!");
});
speech:start
This event triggers when the widget starts recording voice input
stackchat.on("speech:start", function () {
console.log("Widget is recording now!");
});
speech:end
This event triggers when the widget stops recording voice input
stackchat.on("speech:end", function () {
console.log("Widget has stopped recording now!");
});
speech:error
This event triggers when the widget encounters an error while recording voice input
stackchat.on("speech:error", function (error) {
console.log(error.type, error.message);
});
Embedded Mode
As describe above, to activate the embedded mode, you need to pass embedded: true
when calling stackchat.init
. By doing so, you are disabling the auto-rendering mechanism and you will need to call stackchat.render
manually. This method accepts a DOM element which will be used as the container where the widget will be rendered.
The embedded widget will take full width and height of the container. You must give it a height, otherwise, the widget will collapse.
Proactive Messaging
Introduction
This feature allows you to handle the creation, display and manipulation of messages that are proactively displayed to the user. A user can also interact with these messages eliminating the need of guesswork from the user.
Proactive messages can be triggered automatically during an ongoing conversation in the Stackchat Web Messenger or can be manually triggered as the need arises.
Each proactive message looks like this(when default styles are used)
or like this with actions:
Note: Proactive messages are only displayed if and only if the messenger widget is not open. If it is open, then all the proactive messages are silently ignored.
Example
// Initialise Web Messenger
Stackchat.init({
// ...config
proactiveMessaging: {
ttl: 4000 // default
author: "Test Bot"
}
})
API
Initialisation Options
See the configuration object at the top for more details.
Configuring a Proactive Message
As long as the messenger widget is not open, ProactiveMessaging
any message containing the proactive
property in its metadata
that has been set to true
will displayed proactively.
// Therefore the message object should look like this
message = {
metadata: {
proactive: true,
...otherMetaProps
},
...otherMessageProps
};
Methods
addProactiveMessage({text, persona, quickReplies})
Allows the developer to simulate or display a proactive message to the user without it becoming a part of the ongoing conversation.
For e.g.
// Without actions
stackchat.addProactiveMessage({ text: "Hello, world!" });
// With actions
stackchat.addProactiveMessage({
text: "Hello, world!",
quickReplies: [
{
text: "Hello there!",
openMessengerOnReply: false
},
{
text: "Hi! What are you up to?",
openMessengerOnReply: true
}
]
});
Event Binding
ProactiveMessaging
offers two special methods to allow developers to react to events as they occur.
Note: You can add and remove event binding at any time.
-
on(event, handler)
Allows you to specify a callback for a event which is called when that aforesaid event occurs.
-
off(event?, handler?)
Allows you to remove a callback tied to an event. If no handler is specfied, it removes all the callbacks associated with the event. If no event has been specified, all callbacks for all events are cleared.
Events
This is the list of events that you can use with on
and off
methods as described above.
-
ready
This event is fired when your
ProactiveMessaging
instance is ready. From this point on, it can start displaying proactive messages.stackchat.on("ready", () => { console.log("Proactive Messaging is ready!"); });
-
proactive-message:clicked
This event is fired when a user clicks on a proactive message. This event is not fired when a user dismisses a message or clicks on a quick reply.
stackchat.on("proactive-message:clicked", (event) => { console.log("Proactive Message clicked > message", event.message); });
-
proactive-message:dismissed
This event is fired when a user dismisses a proactive message. It is not fired if the message auto dismisses after the
ttl
.stackchat.on("proactive-message:dismissed", (event) => { console.log("Proactive Message dismissed > message", event.message); });
-
quick-reply:clicked
This event is fired when a user clicks on one of the quick replies in a proactive message.
stackchat.on("quick-reply:clicked", (event) => { console.log("Quick reply clicked"); console.log("Message", event.message); console.log("Quick reply", event.quickReply); });
-
messenger:opened
This event is fired whenever the Stackchat Web Messenger is opened by your
ProactiveMessaging
instance. Stackchat Web Messenger is opened when a user clicks on a message or clicks on one of the quick replies. Refer to the first part of the API section above.stackchat.on("messenger:opened", () => { console.log("Stackchat Web Messenger opened"); });
-
clear
This event is fired when all the proactive messages have been cleared - by user interaction or otherwise. Consider this as a blank slate similar to right after the
ready
event has occured.stackchat.on("clear", () => { console.log("All proactive messages cleared!"); });
Styling
Default Styles
This library includes some base styles that display proactive messages in the nice UI as shown above here and here.
Consuming default styles depends on the way you integrate this library:
-
Script
You can use our CDN hosted stylesheet via a
script
tag<link type="text/css" src="https://assets.au.stackchat.com/sdk/proactive-messaging/1.0.4/main.css" />
-
Package Manager
When using a package manager like npm
or yarn
, the default styling is already included within the messenger project. In instances where you want to povide additional styles or override certain styles belonging to proactive messaging classes take a look at the custom styles section below to learn more about applying your specific styles to the proactive messages.
Custom Styles
The following css sheet is the complete list of proactive messaging styles available, you can extends or override any of these by simply adding your own styles using the same class names, just ensure that your stylesheet is loaded after this sheet has been injected into the head of your document.

Note that an equivalent configuration can be done server side.
According to the channels you use, other domains may need to be added (these are used to display QR codes to link to the Stackchat Web Messenger conversation):
- LINE: https://qr-official.line.me
- WeChat: https://mp.weixin.qq.com
Note that your CSP configuration should also include any domains used to host images or files sent in messages.
If you require blob:
to be excluded for img-src
, you must disable the image upload feature via the init settings.
