Usage

Script Tag

Add the following code towards the end of the head section on your page and replace <app-id> with your app id at the end of the script.

<script>
    !function(e,n,t,r){
        function o(){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 s,p,a,i=[],c=[];e[t]={init:function(){s=arguments;var e={then:function(n){return c.push({type:"t",next:n}),e},catch:function(n){return c.push({type:"c",next:n}),e}};return e},on:function(){i.push(arguments)},render:function(){p=arguments},destroy:function(){a=arguments}},e.__onWebMessengerHostReady__=function(n){if(delete e.__onWebMessengerHostReady__,e[t]=n,s)for(var r=n.init.apply(n,s),o=0;o<c.length;o++){var u=c[o];r="t"===u.type?r.then(u.next):r.catch(u.next)}p&&n.render.apply(n,p),a&&n.destroy.apply(n,a);for(o=0;o<i.length;o++)n.on.apply(n,i[o])};var u=new XMLHttpRequest;u.addEventListener("load",o),u.open("GET","https://"+r+".webloader.smooch.io/",!0),u.responseType="json",u.send()
    }(window,document,"Smooch","<app-id>");
</script>

then initialize the Web Messenger by placing this snippet towards the end of the body section of your page.

<script>
    Smooch.init({appId: '<app-id>'}).then(function() {
        // Your code after init is complete
    });
</script>

}).then(function() {
    // Your code after init is complete
});


skPromise.then(function() {
    // do something
});

// pass it around...

skPromise.then(function() {
    //do something else
});

open()

Opens the conversation widget (noop when embedded)

Smooch.open();

close()

Closes the conversation widget (noop when embedded)

Smooch.close();

isOpened()

Tells if the widget is currently opened or closed.

Smooch.isOpened();

login(userId , jwt)

Logs a user in the Web Messenger, retrieving the conversation the user already had on other browsers and/or devices. Note that you don't need to call this after init if you passed the user id and jwt already, it's done internally. This returns a promise that resolves when the Web Messenger is ready again.

Smooch.login('some-id', 'some-jwt');

logout()

Logs out the current user and reinitialize the widget with an anonymous user. This returns a promise that resolves when the Web Messenger is ready again.

Smooch.logout();

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 Smooch.on.

Smooch.destroy();

sendMessage(message)

Sends a message on the user's behalf

Smooch.sendMessage({
    type: 'text',
    text: 'hello'
});

// OR

Smooch.sendMessage('hello');

triggerPostback(actionId)

Trigger a postback action on the user's behalf. The actionId is the _id property of the targeted action.

If you have the _id of the targetted postback action, you can pass it directly to triggerPostback.

const actionId = '5a747faa065bbe4e7804f2a4';
Smooch.triggerPostback(actionId);

Otherwise, you can get the _id of an action by using Smooch.getConversation(), e.g.

const conversation = Smooch.getConversation();

console.log(conversation.messages);
// [
//     {
//         "text": "Do you want to continue?",
//         "actions": [
//             {
//                 "payload": "text:continue",
//                 "text": "Continue conversation",
//                 "_id": "5a7c65211aaa9b61f69c95e3",
//                 "type": "postback"
//             }
//         ],
//         "type": "text",
//         "role": "appMaker",
//         "_id": "5a7c65211aaa9b61f69c95e2",
//         // ...
//     }
// ]

// Indicate to Smooch that the user has clicked on the "Continue conversation" postback action.
Smooch.triggerPostback(conversation.messages[0].actions[0]._id);

updateUser(user)

Updates user information

Smooch.updateUser({
    givenName: 'Updated',
    surname: 'Name',
    email: 'updated@email.com',
    properties: {
      'justGotUpdated': true
    }
});

getUser()

Returns the current user.

var user = Smooch.getUser()

getConversation()

Returns the conversation if it exists

var conversation = Smooch.getConversation();

startConversation()

Creates a user and conversation on the server, allowing the business to reach out proactively to the user via the public API.

Creating a conversation via this method will count as an active user conversation (AUC) whether messages are exchanged or not, which may incur cost based on your plan. 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.

Smooch.startConversation();

markAllAsRead()

Marks all unread messages as read.

Smooch.markAllAsRead();

showNotificationChannelPrompt()

Displays a prompt to the user suggesting the linking of the current chat instance with other 3rd-party apps.

Smooch.showNotificationChannelPrompt();

setPredefinedMessage(message)

Prefills the user's chat input with a predefined message.

Smooch.setPredefinedMessage(message);

setDelegate(delegate)

Sets a delegate on the conversation. See the delegate section for more details.

Smooch.setDelegate(delegate);

Delegate

Smooch allows you to set a delegate to receive callbacks when important changes happen in the conversation. To set a delegate, use the setDelegate method.

beforeSend

The beforeSend delegate method allows you to modify properties of a message before sending it to Smooch. The modified message must be returned for it to take effect.

A common usage of this method is to add message metadata.

Smooch.setDelegate({
    beforeSend: (message) => {
        message.metadata = {
            any: 'info'
        };

        return message;
    }
});

Events

If you want to make sure your events are triggered, try to bind them before calling Smooch.init.

To bind an event, use Smooch.on(<event name>, <handler>);. To unbind events, you can either call Smooch.off(<event name>, handler) to remove one specific handler, call Smooch.off(<event name>) to remove all handlers for an event, or call Smooch.off() to unbind all handlers.

ready

// This event triggers when init completes successfully... Be sure to bind before calling init!
Smooch.on('ready', function(){
    console.log('the init has completed!');
});

Smooch.init(...).then(function() {
    // init also returns a promise, so you can alternatively specify a .then() callback
});

destroy

// This event triggers when the widget is destroyed.
Smooch.on('destroy', function(){
    console.log('the widget is destroyed!');
});

Smooch.destroy();

message:received

// This event triggers when the user receives a message
Smooch.on('message:received', function(message) {
    console.log('the user received a message', message);
});

message:sent

// This event triggers when the user sends a message
Smooch.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
Smooch.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
Smooch.on('unreadCount', function(unreadCount) {
    console.log('the number of unread messages was updated', unreadCount);
});

widget:opened

// This event triggers when the widget is opened
Smooch.on('widget:opened', function() {
    console.log('Widget is opened!');
});

widget:closed

// This event triggers when the widget is closed
Smooch.on('widget:closed', function() {
    console.log('Widget is closed!');
});

Embedded mode

As describe above, to activate the embedded mode, you need to pass embedded: true when calling Smooch.init. By doing so, you are disabling the auto-rendering mechanism and you will need to call Smooch.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.

Content Security Policy

If your deployment requires CSP compatibility, add the following meta tag to your configuration.

<meta http-equiv="Content-Security-Policy" content="
    connect-src
        wss://*.smooch.io
        https://*.smooch.io;
    font-src
        https://*.smooch.io;
    script-src
        https://*.smooch.io;
    style-src
        https://*.smooch.io;
    img-src
        blob:
        https://*.smooch.io;">

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 the Web Messenger conversation):

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.
