Adding the web chat to your website

{: #deploy-web-chat}

Add your assistant to your company website as a web chat widget that can help your customers with common questions and tasks, and can transfer customers to human agents. {: shortdesc}

When you create a web chat integration, code is generated that calls a script that is written in JavaScript. The script instantiates a unique instance of your assistant. You can then copy and paste the HTML script element into any page or pages on your website where you want users to be able to ask your assistant for help.

To learn more about how web chat can help your business, read this Medium blog post{: external}.

Create a web chat instance to add to your website

{: #deploy-web-chat-task}

To add the assistant to a web page on your company website, complete the following steps:

  1. From the Assistants page, click to open the assistant tile that you want to deploy to your site.

  2. From the Integrations section, either click Integrate web chat, or click Add integration, and then choose the Web chat tile.

    The web chat integration is added to your first assistant automatically. If you're using the My first assistant, click the Web chat tile to open the integration that was added for you.

  3. Optional: Change the web chat integration name from Web chat to something more descriptive.

    A preview pane is displayed that shows you what the web chat looks like when it is embedded in a web page. If a message is displayed that starts with, There is an error, it means you haven't added a conversational skill to your assistant yet. After you add a skill, you can test the conversation from the preview pane. {: tip}

  4. Click Create to create a web chat instance.

    You can skip this step if the web chat integration was created for you automatically.

    Plus or higher plans only For environments where private endpoints are in use, keep in mind that the web chat integration sends traffic over the internet. For more information, see Private network endpoints. {: note}

  5. Optional: Customize the style of the chat window. You can make the following changes:

    • Assistant's name as known by customers: The name by which the assistant is known to users. This name is displayed in the header of the chat window. The name can be up to 64 characters in length.

    • Primary color: The color of the web chat header.

      Click the white dot to open a color switcher where you can choose a color. The color is saved as an HTML color code, such as #FF33FC for pink and #329A1D for green. Alternatively, you can add an HTML color code directly to the field to set the color.

    • Secondary color: The color of the user input message bubble.

    • Accent color: The color of interactive elements, including:

      • Chat launcher button that is embedded in your web page
      • Send button associated with the input text field
      • Input text field border when in focus
      • Marker that shows the start of the assistant’s response
      • Border of a button after it is clicked
      • Border of the drop-down list field as the user chooses an option
      • Typing indicator that is shown to repesent a pause response

    Style changes you make are immediately applied to the preview that is shown on the page, so you can see how your choices impact the style of the chat UI.

    • IBM Watermark: Enables or disables the Built with IBM Watson watermark displayed in the web chat window. The watermark is always enabled for any new web chat integrations on Lite plans.
  6. If you want to add an image that represents your assistant or organization to the web chat header, click Add an avatar image.

    Specify the URL for a publicly accessible hosted image, such as a company or brand logo or an assistant avatar. The image file must be between 64 x 64 and 100 x 100 pixels in size.

    Click Save.

  7. Configure the home screen for the chat window.

    The home screen helps to ease your customers into a conversation with your assistant. You can add a greeting and a list of quick conversation starter questions for customers to click. For more information, see Configuring the home screen.

    If you don't want to use a home screen, go to the Home screen tab and toggle the switch to Off.

  8. Optional: To configure support for transferring conversations to a service desk agent, click the Live agent tab. For more information, see Adding service desk support.

  9. Optional: The web chat gives your customers a way to reset the conversation if they get stuck by showing them a list of suggestions. Suggestions are enabled automatically. You can control how often suggestions are displayed and what they include. Click the Suggestions tab. For more information, see Showing more suggestions.

  10. Optional: To secure the web chat, click the Security tab. For more information, see Securing the web chat.

  11. Click the Embed tab.

    A code snippet is displayed that defines the chat window implementation. You will add this code snippet to your web page. The code snippet contains an HTML script element. The script calls JavaScript code that is hosted on an IBM site. The code creates an instance of a widget that communicates with the assistant. The generated code includes a region and unique integration ID. Do not change these parameter values.

  12. Copy the script HTML element. You add this script to your website in the next section, Deploy your assistant in production.

  13. If you made any customizations, click Save and exit. Otherwise, click Close.

    The web chat instance is created as soon as you click the Create button, and does not need to be saved.

Deploy your assistant in production

{: #deploy-web-chat-snippet}

  1. If the system that hosts your website has limited Internet access (for example, if you use a proxy or firewall), make sure the following URLs are accessible:

    • https://web-chat.global.assistant.watson.appdomain.cloud: Hosts the code for the web chat widget, and is referenced by the script you embed on your website.
    • https://integrations.{location}.assistant.watson.appdomain.cloud: Hosts the web chat server, which handles communication with your assistant. Replace {location} with the location of the data center where your service instance is located, which is part of the service endpoint URL. For more information, see Finding and updating the endpoint URL{: external}.
  2. Open the HTML source for a web page on your website where you want the chat window to be displayed. Paste the code snippet into the page.

    Paste the code as close to the closing </body> tag as possible to ensure that your page renders faster. {: tip}

    The following HTML snippet is the source for a test page that you can copy and save as a file with a .html extension for testing purposes. You would replace the script element block here with the script elements you copied from the web chat integration setup page.

    <html>
    <head></head>
    <body>
        <title>My Test Page</title>
        <p>The body of my page.</p>
        
        </body>
    </html>

    {: codeblock}

  3. Refresh the web page.

    For information about the web browsers that are supported by the web chat, see Browser Support.

    Chat icon

    The web chat launcher icon is displayed at the end of the page. The icon is blue unless you customize the accent color.

    The placement of the web chat icon is always the same regardless of where you paste the script element into the web page source. The chat window is represented by a div HTML element. {: important}

    A developer can make more involved style changes, such as changing the launcher icon and its placement or the size and position of the chat window. For more information, see Applying advanced customizations.

  4. Click the icon to open the chat window and talk to your assistant.

    Web chat window

  5. Paste the code snippet into each web page where you want the assistant to be available to your customers.

    You can paste the same script tag into as many pages on your website as you want. Add it anywhere where you want users to be able to reach your assistant for help. However, be sure to add it only one time per page. {: tip}

  6. Submit test utterances from the chat widget that is displayed on your web page to see how the assistant responds.

    No responses are returned until after you create a dialog skill and add it to the assistant. {: attention}

    If the Connect to agent button is displayed and you don't have human agent support configured, you can hide it by changing the Suggestions configuration. For more information, see Showing more suggestions. {: note}

    If you don't extend the session timeout setting for the assistant, the dialog flow for the current session is restarted after 60 minutes of inactivity. This means that if a user stops interacting with the assistant, after 60 minutes, any context variable values that were set during the previous conversation are set to null or back to their initial values.

A developer can use APIs to apply more advanced customizations to the style of the web chat. For more information, see Applying advanced customizations.

Launcher appearance and behavior

{: #deploy-web-chat-launcher}

The web chat launcher welcomes and engages customers so they know where to find help if they need it. By default, the web chat launcher appears in a small initial state as a circle in the bottom right corner:

An example of the initial launcher

After 15 seconds, the launcher expands to show a greeting message to the user. In this expanded state, a customer can still click the launcher to open the web chat. (If the customer reloads the page or navigates to a different page before the launcher has expanded, the 15-second timer restarts.) There are two slightly different appearances for this expanded state, depending on whether the user is using a desktop browser or a mobile browser.

  • For desktop browsers, the expanded launcher shows two primary buttons the customer can click to open the web chat, and a Close button that closes the launcher:

    An example of the desktop launcher

    The expanded launcher remains in its expanded state even if the customer reloads the page or navigates to a different page. It stays in its expanded state until the customer either opens it by clicking on either of the two primary buttons, or closes it, at which point it returns to its initial small state for the rest of the session.

  • For mobile browsers, the launcher shows only a single primary button:

    An example of the mobile launcher

    The customer can close the launcher by scrolling on the page, swiping right on the expanded launcher, or waiting 10 seconds, at which point the expanded launcher shrinks back to its initial small state automatically. If the user reloads the page or navigates to a different page while the laucher is expanded, it stays in its expanded state, and the 10-second timer restarts.

The color of the launcher is specified by the Accent color field on the Style tab of the web chat settings. To change the color, specify a new color using a standard hexadecimal RGB value.

You can customize the greeting message displayed by the launcher on the Launcher tab of the web chat settings. The settings include separate greeting messages for the desktop and mobile versions of the launcher.

The language of the default text shown within the launcher depends on the locale configured for the web chat. For more information, see Languages{: external}. If you customize the greeting text, the text you provide is used regardless of the locale settings. {: note}

Configuring the home screen

{: #deploy-web-chat-home-screen}

By default, the web chat window shows a home screen that can welcome users and tell them how to interact with the assistant. The home screen replaces any greeting that would otherwise be sent by a Welcome node in a dialog skill, or by the Greet customer system action in an actions skill. (If you prefer to use a Welcome node or a Greet customer system action instead of the home screen, you can disable the home screen on the Home screen tab.)

An example of the home screen

  1. Add a greeting that is engaging and invites the user to interact with your assistant. A greeting is required.

  2. Add three conversation starter messages.

    These messages are displayed in the web chat as examples of the types of questions that customers can ask. Customers can click one of them to submit it to the assistant.

    You must test each message that you add as a conversation starter. Use only questions that the assistant understands and knows how to answer well.

    If your assistant has multiple skills attached to it, the dialog skill orchestrates the incoming messages. If you want an action that you created to respond to a conversation starter message, make sure your dialog is set up to call the action. For more information, see Calling an actions skill from a dialog.

    All three conversation starters are required.

A developer can customize the home screen even more:

  • A Get started heading is displayed before the list of conversation starter messages. A developer can change the heading text by replacing the homeScreen_conversationStarterLabel in the web chat language strings file. For more information, see the instance.updateLanguagePack() method{: external} documentation.
  • You can use the web chat API to add other elements to the home screen page. For more information, see the instance.writeableElements() method{: external} documentation.
  • For information about CSS helper classes that you can use to change the home screen style, see the prebuilt templates{: external} documentation.

Showing more suggestions

{: #deploy-web-chat-alternate}

Suggestions give your customers a way to try something else when the current exchange with the assistant isn't delivering what they expect. A question mark icon Question mark icon is displayed in the web chat that customers can click at any time to see other topics that might be of interest or, if configured, to request support. Customers can click a suggested topic to submit it as input or click the X icon to close the suggestions list.

Starting with web chat version 3.1, if customers select a suggestion and the response is not helpful, they can open the suggestions list again to try a different suggestion. The input generated by the first choice is submitted and recorded as part of the conversation. However, any contextual information that is generated by the initial suggestion is reset when the subsequent suggestion is submitted.

The suggestions are shown automatically in situations where the customer might otherwise become frustrated. For example, if a customer uses different wording to ask the same question multiple times in succession, and the same dialog node is triggered each time, then related topic suggestions are shown in addition to the triggered node's response. The suggestions that are offered give the customer a quick way to get the conversation back on track.

The suggestions list is populated with dialog nodes that condition on intents that are related in some way to the matched intent. The intents are ones that the AI model considered to be possible alternatives, but that didn't meet the high confidence threshold that is required for a node to be listed as a disambiguation option. Any dialog node with a node name (or external node name) can be shown as a suggestion, unless its Show node name setting is set to Off.

To customize suggestions, complete the following steps:

  1. Open the Suggestions tab.

    The Suggestions feature is enabled automatically for new web chat integrations. If it's not enabled, set the Suggestions switch to On.

    The Include a connection to support section is displayed where you can configure whether and how to give customers the ability to connect with support.

  2. Decide when you want an option to connect with support to be shown in the suggestions list. The choices are:

    • Always: Always shows the option to get support in the list of suggestions.
    • Never: Never shows the option to get support in the list of suggestions.
    • After one failed attempt: Adds the option to the list only if the customer reached a node with an anything_else condition in the previous conversation turn or reaches the same dialog node for a second time in succession.
  3. In the Option label field, add a label for the option.

    The text in the Option label field has two functions:

    • The text is shown in the suggestions list as an option for customers to select.
    • When selected by a customer, the text is sent to your assistant as a new message. The label must be able to function as input that your dialog understands and knows how to handle.

    By default, the option label Connect with agent is used. If your web chat is integrated with a service desk, this message initiates a conversation transfer, as long as your dialog is designed to handle transfer requests.

    If your web chat is not integrated with a service desk, you can change the option label to a message that helps your customers reach whatever form of support you do offer. If you offer a toll-free support line, you might add Get the support line phone number. Or if you offer an online support request form, you might add Open a support ticket.

    Whether you use the default option label or add your own, make sure your dialog is designed to recognize the message and respond to it appropriately. For more information, see Connecting customers with support.

With web chat version 2.4 only, you cannot enable suggestions unless your web chat is connected to a service desk solution. Later releases allow you to enable suggestions whether or not you have human agent support configured. {: note}

Dialog considerations

{: #deploy-web-chat-dialog}

The rich responses that you add to a dialog are displayed in the web chat as expected, with the following exceptions:

  • Connect to human agent: If service desk support is enabled for the web chat, this response type triggers a chat transfer. If service desk support is not configured, this response type is ignored.
  • Option: If your option list contains up to four choices, they are displayed as buttons. If your list contains five or more options, then they are displayed in a drop-down list.
  • Pause: This response type pauses the assistant's activity in the chat. However, activity does not resume after the pause until another response is triggered. Whenever you include a pause response type, add another, different response type, such as text, after it.

For more information about rich response types, see Rich responses.

If you want to use the same dialog for an assistant that you deploy to many different platforms, add custom responses per integration type. You can add a conditioned response that tells the assistant to show the response only when the web chat integration is being used. For more information, see Building integration-specific responses.

Web chat security

{: #deploy-web-chat-security}

Configure the web chat to authenticate users and send private data from your embedded web chat. For more information, see Securing the web chat.

Adding service desk support

{: #deploy-web-chat-haa}

Delight your customers with 360-degree support by integrating your web chat with a third-party service desk solution.

The following service desk offerings are supported:

Fully functional reference implementations are provided for the following service desks:

The starter kit reference implementations, while functional, are examples only, and have not been vetted for production use. You should perform robust testing before deploying these integrations in production. {: important}

  • Bring your own{: external}: A web chat service desk extension starter kit that enables you to develop your own service desk integrations.

After you set up the service desk integration, you must update your dialog to ensure it understands user requests to speak to someone, and can transfer the conversation properly. For more information, see Adding chat transfer support.

Web chat integration limits

{: #deploy-web-chat-limits}

The usage is measured differently depending on the plan type. For Lite plans, usage is measured by the number of /message calls (API) are sent to the assistant from the web chat integration. For all other plans, usage is measured by the number of monthly active users (MAU) that the web chat interacts with. The maximum number of allowed MAUs differs depending on your {{site.data.keyword.assistant_classic_short}} plan type.

Plan Maximum usage
Enterprise Unlimited MAU
Premium (legacy) Unlimited MAU
Plus Unlimited MAU
Trial 5,000 MAU
Lite 10,000 API (approximately 1,000 MAU)
{: caption="Plan details" caption-side="top"}

For more information about how the web chat widget tracks MAUs, see Billing.
