## 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! 🙂

## Common Scenarios

### Pre-Chat Survey

> See https://docs.microsoft.com/en-us/dynamics365/customer-service/configure-pre-chat-survey?tabs=customerserviceadmincenter on how to set up pre-conversation surveys

```ts
    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);
        }} />
    }

```

### Post-Chat Survey

> See https://docs.microsoft.com/en-us/dynamics365/customer-service/configure-post-conversation-survey?tabs=customerserviceadmincenter on how to set up post-conversation surveys

> ❗ `chatSDK.getPostChatSurveyContext()` needs to be called before `chatSDK.endChat()` is called

```ts
// 1. Start chat
await chatSDK.startChat();

// 2. Save post chat survey context before ending chat
try {
    const context = await chatSDK.getPostChatSurveyContext();
    if (context.participantJoined) { // participantJoined will be true if an agent has joined the conversation, or a bot has joined the conversation and the bot survey flag has been turned on on the admin side.
        // formsProLocale is the default language you have set on the CustomerVoice portal. You can override this url parameter with any locale that CustomerVoice supports.
        // If "&lang=" is not set on the url, the locale will be English.
        const link = context.participantType === "Bot" ? context.botSurveyInviteLink : context.surveyInviteLink;
        const locale = context.participantType === "Bot" ? context.botFormsProLocale : context.formsProLocale;
        const linkToSend = link + "&lang=" + locale;
        // This link is accessible and will redirect to the survey page. Use it as you see fit.
    }
} catch (ex) {
    // If the post chat should not be shown by any reason (e.g. post chat is not enabled), promise will be rejected.
}

// 3. End chat
await chatSDK.endChat();

// 4. Display Post Chat
```

### Reconnect to existing Chat

```ts
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

> See https://docs.microsoft.com/en-us/dynamics365/customer-service/create-chat-auth-settings?tabs=customerserviceadmincenter#create-a-chat-authentication-setting-record on how to set up an authenticated chat

```ts
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
```

### Persistent Chat

> See https://docs.microsoft.com/en-us/dynamics365/customer-service/persistent-chat on how to set up persistent chat

```ts
const chatSDKConfig = {
    persistentChat: {
        disable: false,
        tokenUpdateTime: 21600000
    },
    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 persistent chat
```
### Chat Reconnect with Authenticated User

> See https://docs.microsoft.com/en-us/dynamics365/customer-service/configure-reconnect-chat?tabs=customerserviceadmincenter#enable-reconnection-to-a-previous-chat-session on how to set up chat reconnect

```ts
const chatSDKConfig = {
    chatReconnect: {
        disable: false,
    },
    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();

...

const chatReconnectContext = await chatSDK.getChatReconnectContext();

if (chatReconnectContext.reconnectId) {
    // Add UX with options to reconnect to previous existing chat or start new chat
}

// Reconnect chat option
const optionalParams = {};
optionalParams.reconnectId = chatReconnectContext.reconnectId;
chatSDK.startChat(optionalParams);

// Start new chat option
chatSDK.startChat();

const urlParams = new URLSearchParams(window.location.search);
const reconnectId = urlParams.get('oc.reconnectid');

const params = {
    reconnectId
};

// Validate reconnect id
const chatReconnectContext = await chatSDK.getChatReconnectContext(params);

// If the reconnect id is invalid or expired, redirect URL if there is any URL set in the configuration
if (chatReconnectContext.redirectURL) {
    window.location.replace(chatReconnectContext.redirectURL);
}

// Valid reconnect id, reconnect to previous chat
if (chatReconnectContext.reconnectId) {
    await chatSDK.startChat({
        reconnectId: chatReconnectContext.reconnectId
    });
} else {  // Reconnect id from URL is not valid, start new chat session
    await chatSDK.startChat();
}
```

## Telemetry

Omnichannel Chat SDK collects telemetry by default to improve the feature’s capabilities, reliability, and performance over time by helping Microsoft understand usage patterns, plan new features, and troubleshoot and fix problem areas.

Some of the data being collected are the following:

| Field | Sample |
| --- | --- |
| Organization Id | `e00e67ee-a60e-4b49-b28c-9d279bf42547` |
| Organization Url | `org60082947.crm.oc.crmlivetie.com` |
| Widget Id | `1893e4ae-2859-4ac4-9cf5-97cffbb9c01b` |
| Browser Name | `Edge` |
| Os Name | `Windows` |
| Anonymized IP Address (last octet redacted) | `19.207.000.000` |

If your organization is concerned about the data collected by the Chat SDK, you have the option to turn off automatic data collection by adding a flag in the `ChatSDKConfig`.

```ts
const omnichannelConfig = {
    orgUrl: "",
    orgId: "",
    widgetId: ""
};

const chatSDKConfig = {
    telemetry: {
        disable: true // Disable telemetry
    }
};

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