Live Chat Widget vs. Chat SDK

Omnichannel offers an live chat widget (LCW) by default. You can use the Chat SDK to build your custom chat widget if:

• You want to fully customize the user interface of the chat widget to conform with your branding.
• You want to integrate Omnichannel in your mobile app using React Native.
• You want to integrate additional functionalities that LCW does not offer.
• Some other cool ideas. Please share with us on what you've achieved with the Chat SDK! 🙂

        liveChatContext: {}, // EXISTING chat context data
        customContext // Custom Context
    };
    await chatSDK.startChat(optionalParams);

End Chat

    await chatSDK.endChat();

On New Message Handler

    await chatSDK.emailLiveChatTranscript(body);

Common Scenarios

PreChatSurvey

    import * as AdaptiveCards, { Action } from "adaptivecards";

    ...

    const preChatSurvey = await chatSDK.getPreChatSurvey();

    ...

    // Web implementation
    const renderPreChatSurvey = () => {
        const adaptiveCard = new AdaptiveCards.AdaptiveCard();
        adaptiveCard.parse(preChatSurvey); // Parses Adaptive Card JSON data
        adaptiveCard.onExecuteAction = async (action: Action) => { // Adaptive Card event handler
            const preChatResponse = (action as any).data;
            const optionalParams: any = {};
            if (preChatResponse) {
                optionalParams.preChatResponse = preChatResponse;
            }
            await chatSDK.startChat(optionalParams);
        }

        const renderedCard = adaptiveCard.render(); // Renders as HTML element
        return <div ref={(n) => { // Returns React element
            n && n.firstChild && n.removeChild(n.firstChild); // Removes duplicates fix
            renderedCard && n && n.appendChild(renderedCard);
        }} />
    }

Reconnect to existing Chat

    await chatSDK.startChat(); // Starts NEW chat

    const liveChatContext = await chatSDK.getCurrentLiveChatContext(); // Gets chat context

    cache.saveChatContext(liveChatContext); // Custom logic to save chat context to cache

    ...

    // Page/component reloads, ALL previous states are GONE

    ...

    const liveChatContext = cache.loadChatContext() // Custom logic to load chat context from cache

    const optionalParams = {};
    optionalParams.liveChatContext = liveChatContext;

    await chatSDK.startChat(optionalParams); // Reconnects to EXISTING chat

    ...

    const messages = await chatSDK.getMessages(); // Gets all messages from EXISTING chat
    messages.reverse().forEach((message: any) => renderMessage(message)); // Logic to render all messages to UI

Authenticated Chat

    // add if using against an authenticated chat endpoint
    // see https://docs.microsoft.com/en-us/dynamics365/omnichannel/administrator/create-chat-auth-settings on how to set up an authenticated chat widget

    const chatSDKConfig = {
        getAuthToken: async () => {
            const response = await fetch("http://contosohelp.com/token");
            if (response.ok) {
                return await response.text();
            }
            else {
                return null
            }
        }
    }

    const chatSDK = new OmnichannelChatSDK.OmnichannelChatSDK(omnichannelConfig, chatSDKConfig);
    await chatSDK.initialize();

    // from this point, this acts like a regular chat widget

Use BotFramework-WebChat

NOTE: Currently supported on web only

    import OmnichannelChatSDK from '@microsoft/omnichannel-chat-sdk';
    import ReactWebChat from 'botframework-webchat';

    ...

    const chatSDK = new OmnichannelChatSDK.OmnichannelChatSDK(omnichannelConfig, chatSDKConfig);
    await chatSDK.initialize();

    const optionalParams = {
        preChatResponse: '' // PreChatSurvey response
    };

    await chatSDK.startChat(optionalParams);
    const chatAdapter = await chatSDK.createChatAdapter();

    // Subscribes to incoming message (OPTION 1)
    chatSDK.onNewMessage((message) => {
      console.log(`[NewMessage] ${message.content}`); // IC3 protocol message data
      console.log(message);
    });

    // Subscribes to incoming message (OPTION 2)
    (chatAdapter as any).activity$.subscribe((activity: any) => {
        if (activity.type === "message") {
            console.log("[Message activity]");
            console.log(activity); // DirectLine protocol activity data
        }
    });

    ...

    <ReactWebChat
        userID="teamsvisitor"
        directLine={chatAdapter}
        sendTypingIndicator={true}
    />

            OCClient: chatSDK.OCClient
        });
    } catch (e) {
        console.error("Failed to initialize VoiceVideoCalling!");
    }

    // Triggered when there's an incoming call
    VoiceVideoCallingSDK.onCallAdded(() => {
        ...
    });

    // Triggered when local video stream is available (e.g.: Local video added succesfully in selfVideoHTMLElement)
    VoiceVideoCallingSDK.onLocalVideoStreamAdded(() => {
        ...
    });

    // Triggered when local video stream is unavailable (e.g.: Customer turning off local video)
    VoiceVideoCallingSDK.onLocalVideoStreamRemoved(() => {
        ...
    });

    // Triggered when remote video stream is available (e.g.: Remote video added succesfully in remoteVideoHTMLElement)
    VoiceVideoCallingSDK.onRemoteVideoStreamAdded(() => {
        ...
    });

    // Triggered when remote video stream is unavailable (e.g.: Agent turning off remote video)
    VoiceVideoCallingSDK.onRemoteVideoStreamRemoved(() => {
        ...
    });

    // Triggered when current call has ended or disconnected regardless the party
    VoiceVideoCalling.onCallDisconnected(() => {
        ...
    });

    // Check if microphone is muted
    const isMicrophoneMuted = VoiceVideoCallingSDK.isMicrophoneMuted();

    // Check if remote video is available
    const isRemoteVideoEnabled = VoiceVideoCallingSDK.isRemoteVideoEnabled();

    // Check if local video is available
    const isLocalVideoEnabled = VoiceVideoCallingSDK.isLocalVideoEnabled();

    // Accepts incoming call
    const acceptCallConfig = {
        withVideo: true // Accept call with/without video stream
    };
    await VoiceVideoCallingSDK.acceptCall(acceptCallConfig);

    // Rejects incoming call
    await VoiceVideoCallingSDK.rejectCall();

    // Ends/Stops current call
    await VoiceVideoCallingSDK.stopCall();

    // Mute/Unmute current call
