Web Messenger SDK

This page describes how to get started with the Web Messenger SDK

Prerequisites to Implementing Web Messenger SDK

🚧

Download the Web Messenger SDK before proceeding

Make sure you download the Web Messenger SDK here from DevConnect before continuing through this integration guide

Web Messenger Configuration

📘

First: Start with configuring your public path for the Web Messenger SDK

The AvMessagingSdk library is composed of multiple assets fetched at runtime for better performance.
For that reason, the public path (the URL where files are hosted) is hardcoded in multiple places.

To configure the library for your environment, run:

./configure <new-public-path>

The script will generate a folder with the configured project in it.

Examples

Local testing setup

The static files are hosted at http://localhost:8000/static/ and the script is run in the /home/your-name/ folder.

./configure http://localhost:8000/static/

Files will be available at /home/your-name/http:__localhost:8000_static_/.

Production setup

The static files are hosted at https://cdn.acme.org/.

./configure https://cdn.acme.org/

Files will be available at /home/your-name/https:__cdn.acme.org_/.

Installation instructions for the end user

Instructions on how to integrate the library on a website will be available in the README.md file inside the generated folder.

Content Security Policy

In case your customer's deployment requires CSP compatibility, the following meta tag needs to be included on their site. However, keep in mind that for connect-src Smooch domain will appear and cannot be replaced by yours. Other domains (here acme.org) should be replaced by the domain where files are hosted.

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

Note that an equivalent configuration can be done server side.

According to the channels enabled by your customer, other domains may need to be added (these are used to display QR codes to link the Web Messenger conversation):

Note that the CSP configuration should also include any domains used to host images or files sent in messages.
If a specific deployment requires blob: to be excluded for img-src, image upload must also be disabled via init settings.

Web Messenger Configure Public Path

📘

Second: Deploy the Web Messenger SDK to test your configured public path

Deployment

  1. Put all files from the cdnPackage folder at the root of the storage behind https://{{YOUR_DOMAIN_NAME}}/.
  2. If your storage is behind a CDN, make sure to issue a cache invalidation for https://{{YOUR_DOMAIN_NAME}}/loader.json.
  3. Make sure your server allows CORS requests.
  4. Use the instructions in docs/README.md to test your deployment.

Documentation

Distribute docs/README.md to your users as this document contains everything needed to explain how to initialize and use the Web Messenger.

Web Messenger Customization

📘

Third: Customize the Web Messenger SDK

The AvMessagingSdk Web Messenger will add live web messaging to your website or web app.

Usage

Script Tag

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

<script>
    !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,i=[],c=[];e[t]={init:function(){o=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,o)for(var r=n.init.apply(n,o),s=0;s<c.length;s++){var u=c[s];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(s=0;s<i.length;s++)n.on.apply(n,i[s])};var u=new XMLHttpRequest;u.addEventListener("load",s),u.open("GET","https://{{YOUR_DOMAIN_NAME}}/loader.json",!0),u.responseType="json",u.send()}(window,document,"AvMessagingSdk");
</script>

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

<script>
    AvMessagingSdk.init({integrationId: '<integration-id>'}).then(function() {
        // Your code after init is complete
    });
</script>

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.

AvMessagingSdk.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.

AvMessagingSdk.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 integration id from the Web Messenger. It will also unbind all listeners you might have with AvMessagingSdk.on.

AvMessagingSdk.destroy();

sendMessage(message)

Sends a message on the user's behalf

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

// OR

AvMessagingSdk.sendMessage('hello', '<conversation-id>');

startTyping()

Sends an event indicating the appUser has started typing. When called, a stopTyping timer will be created and will call stopTyping() after 10s, unless stopTyping() has been called manually. Everytime startTyping() is called the timer is reset. If startTyping() is called repeatedly, an event will only be sent if the time since the last sent event is greater then 10s.

If conversationId is not provided, the currently loaded conversation will be used.

AvMessagingSdk.startTyping();

stopTyping()

Sends an event indicating the appUser has stoped typing.

AvMessagingSdk.stopTyping();

triggerPostback(actionId, conversationId)

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.

If conversationId is not provided, the currently loaded conversation will be used.

const actionId = '5a747faa065bbe4e7804f2a4';
AvMessagingSdk.triggerPostback(actionId, '62565b5c2b4039adff80b7fd');

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

const conversation = AvMessagingSdk.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 that the user has clicked on the "Continue conversation" postback action.
AvMessagingSdk.triggerPostback(conversation.messages[0].actions[0]._id);

updateUser(user)

Updates user information

AvMessagingSdk.updateUser({
    givenName: 'Updated',
    surname: 'Name',
    email: '[email protected]',
    properties: {
      'justGotUpdated': true
    }
});

getUser()

Returns the current user.

var user = AvMessagingSdk.getUser()

getConversation()

Returns the conversation if it exists

var conversation = AvMessagingSdk.getConversation();

// Data object
conversation = {
    _id: '<conversation-id>',
    unreadCount: 0,
    lastUpdatedAt: 1581010017.596,
    type: "personal",
    participants: [
        {
            _id: '<participant-id>',
            appUserId: '<appUser-id>',
            unreadCount: 0,
            lastRead: 1581010017.596
        }
    ],
    metadata: {},
    messages: [
        {
            role: 'appUser',
            authorId: '6ac41c8b32e704f3cdb9052d',
            name: 'Some user',
            _id: '5e6022c9cb55158bfd53f845',
            type: "text",
            received: 1583358665.139,
            text: 'Hello',
            source: {
                type: 'web',
                id: 'c38ae913af7c4ef3800b339ee529c579',
                integrationId: '5d8274d4aa780a5483f0ee56'
            }
        }
    ]
}

loadConversation(conversationId)

Loads a conversation into the current session

AvMessagingSdk.loadConversation('<conversation-id>');

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.

AvMessagingSdk.startConversation();

markAllAsRead()

Marks all unread messages as read.

AvMessagingSdk.markAllAsRead();

showNotificationChannelPrompt()

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

AvMessagingSdk.showNotificationChannelPrompt();

setPredefinedMessage(message)

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

AvMessagingSdk.setPredefinedMessage(message);

setDelegate(delegate)

Sets a delegate on the conversation. AvMessagingSdk must be initialized before calling this method. See the delegate section for more details.

AvMessagingSdk.setDelegate(delegate);

Delegate

AvMessagingSdk allows you to set a delegate to receive callbacks when important changes happen in the conversation.
To set a delegate, pass the delegate parameter in to init options, or use the setDelegate method. The delegate object may optionally contain beforeDisplay, beforeSend, beforePostbackSend and onInvalidAuth delegate functions.

A data object is passed down with all the delegate events except onInvalidAuth. This is a read-only object containing a truncated version of the conversation associated with the event.

const delegate = {
    beforeDisplay(message, data) {
        if (data.conversation._id === '<my-conversation-id>') {
            message.name = 'Acme Blank';
        }

        return message;
    },
    beforeSend(message, data) {
        return message;
    },
    beforePostbackSend(postback, data) {
        return postback;
    },
    onInvalidAuth() {
        return new Promise((resolve) =>
            resolve('<my-new-auth-token>')
        )
    }
}

// Passing delegate as an init parameter
AvMessagingSdk.init({
    integrationId: '<integration-id>',
    delegate
});

// Using setDelegate
AvMessagingSdk.init({ integrationId: '<integration-id>' }).then(() => {
    AvMessagingSdk.setDelegate(delegate);
});

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.

AvMessagingSdk.init({
    integrationId: '<integration-id>',
    delegate: {
        beforeDisplay(message, data) {
            if (data.conversation._id === '<conversation-id>' && 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 AvMessagingSdk.
The modified message must be returned for it to take effect.

Note that when a file or an image is uploaded, only the message metadata may be updated. Other message properties such as type or text won't be considered.

AvMessagingSdk.init({
    integrationId: '<integration-id>'
    delegate: {
        beforeSend(message, data) {
            if (data.conversation._id === '<conversation-id>') {
                message.metadata = {
                    any: 'info'
                };
            }

            return message;
        }
    }
});

beforePostbackSend

The beforePostbackSend delegate method allows you to modify properties of a postback before sending it to AvMessagingSdk.
The modified postback must be returned for it to take effect.

AvMessagingSdk.init({
   integrationId: '<integration-id>',
   delegate: {
       beforePostbackSend(postback) {
           if (data.conversation._id === '<conversation-id>') {
               postback.metadata = {
                   any: 'info'
               };
           }

           return postback;
       }
   }
});

onInvalidAuth

The onInvalidAuth delegate notifies the delegate of a failed request due to invalid credentials and allows the implementer to set a new auth token in order to retry the request. The delegate must return a new JWT token as a string or Promise<string> that will resolve into the JWT.

AvMessagingSdk.init({
    integrationId: '<integration-id>',
    delegate: {
        onInvalidAuth() {
            return '<my-new-auth-token>';
        }
    }
});

Events

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

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

ready

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

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

    } else if (data.role === 'appUser') {
        console.log(`Conversation ${data.conversation._id} was read by appUserId: ${payload.appUserId}`);
    }
});

// Data object, if the conversation was read by the appMaker, the appUser property will not exist
payload = {
    appUserId: '<appUser-id>',
    lastRead: 1581010017.596,

AvMessagingSdk.on('typing:start', function(data) {
    console.log(`${data.name} started typing!`, data.conversation._id);
});

// If the name and avatarUrl for the typing user is known it will be available as properties in the data object

// Data object
data = {
    conversation: {
        _id: '<conversation-id>',

});

// data object
data = {
    conversation: {
        _id: '<conversation-id>'
    }
}

Embedded mode

As describe above, to activate the embedded mode, you need to pass embedded: true when calling AvMessagingSdk.init. By doing so, you are disabling the auto-rendering mechanism and you will need to call AvMessagingSdk.render manually. This method accepts a DOM element which will be used as the container where the widget will be rendered.

AvMessagingSdk.init({
    integrationId: '<integration-id>',
    embedded: true
});

AvMessagingSdk.render(document.getElementById('chat-container'));

The embedded widget will take full width and height of the container. You must give it a height, otherwise, the widget will collapse.

Authenticating the user: init() vs login()

For authenticated user scenarios, a user's credentials can be passed in to either init() or login(). The question remains: when should you use which?

When init() is called without a userId and jwt, the UI will be initialized in an anonymous user context, and the user will be able to send messages as an anonymous user. After init() has completed, login() may be called to authenticate the user and resume any existing conversation. This is useful if you want your users to be able to send messages before they've logged in to your website. Once a user does login and the browser is issued a valid jwt, login() may be called so that the user may continue the conversation in an authenticated session.

If however your use case requires that all users be logged in before they may send messages, then you should consider passing userId and jwt directly to the init() call upfront.

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://*.{{YOUR_DOMAIN_NAME}}
        https://*.{{YOUR_DOMAIN_NAME}};
    font-src
        https://*.{{YOUR_DOMAIN_NAME}};
    script-src
        https://*.{{YOUR_DOMAIN_NAME}};
    style-src
        https://*.{{YOUR_DOMAIN_NAME}};
    img-src
        blob:
        https://*.{{YOUR_DOMAIN_NAME}};"
/>

Note that an equivalent configuration can be done server side.

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.
