Setting up Teneo Web Chat

Giving Teneo Web Chat a try

Once you've published your bot, you can interact with it using Teneo Web Chat. On your bots page you will find a list of all solutions for your team. Clicking the Teneo Web Chat button of your published bot opens a new tab with an example page containing Teneo Web Chat. Because the example page does not require a login, you can share it with your colleagues.

Adding Teneo Web Chat to your site

To add the web chat UI to your site, proceed as follows:

Download teneo-web-chat.js

Download the file teneo-web-chat.js from the latest release on Github and add it to your site.

Update pages

Add the following code before the closing tag to each page where you want the web chat window to appear.

<!-- Teneo Web Chat start -->
<div id="teneo-web-chat"></div>
<script src="/path/to/teneo-web-chat.js"></script>
<script>
  window.onload = function () {
    if (
      window.TeneoWebChat &&
        typeof window.TeneoWebChat.initialize === 'function'
    ) {
      var element = document.getElementById('teneo-web-chat');
      const teneoProps = {
        'teneoEngineUrl': 'https://some.teneo/engine-instance/',
      }
      window.TeneoWebChat.initialize(element,teneoProps);
    }
  }
</script>
<!-- Teneo Web Chat end -->

When adding the script to your site, note the following:

• Make sure /path/to/teneo-web-chat.js is replaced with the correct path.
• Make sure https://some.teneo/engine-instance/ is updated to match the URL of your engine.

Embedding Teneo Web Chat using an iFrame

An alternative way of adding Teneo Web Chat to your site is by embedding Teneo Web Chat in an iFrame. That will also enable you to support cross-domain browsing for Teneo Web Chat. You can find a repository with more details and example code here: Teneo Web Chat cross-domain example.

Configuration settings

When initializing Teneo Web Chat, an object containing configuration settings needs to be passed on. In the code above, the object is called teneoProps. The following settings are supported:

Message types

Teneo Web Chat offers various message types that can be 'attached' to the bot's answer text. This is achieved by adding an output parameter teneowebclient with JSON specific for the message type. For more details on how to populate output parameters, see: Populate output parameters in the 'Build your bot' section.

The following message types are supported:

Image

Engine JSON

To add an image, the JSON that should be included in the teneowebclient output parameter looks as follows:

{
    "type": "image",
    "image_url": "https://url.to/an/image.png",
    "thumbnail_url": "https://url.to/a/thumbnail.png",
    "alt": "This is an image"
}

Notes:

• If only the image_url is present, the image will be shown in the chat history as a thumbnail and the image can be clicked to enlarge it
• If only the thumbnail_url is present, the thumbnail image will be shown in the chat history but it cannot be clicked to enlarge it
• If both the image-url and the thumbnail_url are present, the thumbnail_url will be used for the thumbnail in the chat history and when clicked the image_url will be used for the enlarged image

Videos

Teneo Web Chat supports the following video platforms:

• YouTube
• Vimeo
• Mp4 videos

Engine JSON

In general, the JSON to add a video looks like this:

{
    "type": "[videotype]",
    "video_url": "[url]"
}

The type and URL differ depending on the platform that is used to host the video.

YouTube video

{
    "type": "youtubevideo",
    "video_url": "https://www.youtube.com/embed/123456789"
}

Note that the URL of a YouTube video should start with https://www.youtube.com/embed/.

Vimeo video

{
    "type": "vimeovideo",
    "video_url": "https://player.vimeo.com/video/12345678"
}

Note that the URL of a Vimeo video should start with https://player.vimeo.com/video/.

mp4 video

{
    "type": "filevideo",
    "video_url": "https://url.to/a/video.mp4"
}

Note that the type is filevideo.

Audio

To display an audio player, the JSON that should be included in the teneowebclient output parameter looks as follows:

{
    "type": "audio",
    "audio_url": "https://url.to/audio.mp3"
}

Buttons

The title above the buttons is optional. The style attribute in the JSON determines the colors of the buttons. When clicked, a 'postback' value is sent to the engine as a user input. Only buttons in the most recent message can be clicked.

Engine JSON

The JSON that should be included in the teneowebclient output parameter should look as follows:

{
    "type": "buttons",
    "title": "Optional title",
    "button_items": [
        {
            "style": "primary",
            "title": "Primary",
            "postback": "Primary"
        },
        {
            "style": "secondary",
            "title": "Secondary",
            "postback": "Secondary"
        },
        {
            "style": "success",
            "title": "Success",
            "postback": "Success"
        },
        {
            "style": "danger",
            "title": "Danger",
            "postback": "Danger"
        },
        {
            "style": "warning",
            "title": "Warning",
            "postback": "Warning"
        },
        {
            "style": "info",
            "title": "Info",
            "postback": "Info"
        }
    ]
}

If the 'style' of a button is omitted, the primary color is used.

Input parameters

In addition to the above, buttons can contain input parameters that will be included in the request to engine when the user clicks a button. They are defined as follows:

...
    {
        "style": "primary",
        "title": "Primary",
        "postback": "Primary",
        "parameters": { "button": "primary" }
    }
...

In the example above, an input parameter button with value primary will be included in the request to engine when the button is clicked. See How to store input parameters for instructions on how to process input parameters in Studio.

Quick replies

Quick replies behave the same as buttons but are pill-shaped. Quick replies don't have a title. The style attribute in the JSON determines the colors of the quick replies. When clicked, a 'postback' value is sent to the engine as a user input. Only quick replies in the most recent message can be clicked.

Engine JSON

The JSON that should be included in the teneowebclient output parameter should look as follows:

{
    "type": "quickreply",
    "quick_replies": [
        {
            "style": "primary",
            "title": "Primary",
            "postback": "Primary"
        },
        {
            "style": "secondary",
            "title": "Secondary",
            "postback": "Secondary"
        },
        {
            "style": "success",
            "title": "Success",
            "postback": "Success"
        },
        {
            "style": "danger",
            "title": "Danger",
            "postback": "Danger"
        },
        {
            "style": "warning",
            "title": "Warning",
            "postback": "Warning"
        },
        {
            "style": "info",
            "title": "Info",
            "postback": "Info"
        }
    ]
}

Notes:

• If the 'style' of a quick reply is omitted, the primary color is used.
• Just like buttons, quick replies can contain input parameters.

Clickable list

The title above the list of clickable items is optional. When clicked, a 'postback' value is sent to the engine as a user input. Clickable lists don't have a style attribute (like buttons and quick replies). Only clickable lists in the most recent message can be clicked.

Engine JSON

The JSON that should be included in the teneowebclient output parameter should look as follows:

{
    "type": "clickablelist",
    "title": "Optional title",
    "list_items": [
        {
            "title": "One",
            "postback": "One"
        },
        {
            "title": "Two",
            "postback": "Two"
        },
        {
            "title": "Three",
            "postback": "Three"
        },
        {
            "title": "Four",
            "postback": "Four"
        },
        {
            "title": "Five",
            "postback": "Five"
        },
        {
            "title": "Six",
            "postback": "Six"
        }
    ]
}

Note: Just like buttons, clickable lists can contain input parameters.

Link buttons

The title above the link buttons is optional. When clicked, the URL of the link button is opened in the specified target window. Link buttons don't have a style attribute (like buttons and quick replies). Unlike quick replies, they don't expire, but can be clicked even in older messages. They don't return a postback value to engine, but do trigger the On message button clicked event.

Engine JSON

The JSON that should be included in the teneowebclient output parameter looks as follows:

{
    "type": "linkbuttons",
    "title": "Optional title",
    "linkbutton_items": [
        {
            "title": "Link 1",
            "url": "https://url.to/a/page",
            "target": "_blank"
        },
        {
            "title": "Link 2",
            "url": "https://url.to/another/page",
            "target": "_blank"
        },
        {
            "title": "Link 3",
            "link": "https://url.to/yet/another/page"
        }
    ]
}

Tables

The title above the table, the header row, and the footer row are optional. Accepts only text content in the cells, no HTML or additional message templates can be used. The table will expand the number of cells per row to the number of cells in the longest row.

Engine JSON

The JSON that should be included in the teneowebclient output parameter looks as follows:

{
  "type": "table",
  "title": "Table Title",
  "headers": [
    "Header1",
    "Header2",
    "Header3"
  ],
  "body": [
    [
      "Row1 Cell1",
      "Row1 Cell2",
      "Row1 Cell3"
    ],
    [
      "Row2 Cell1",
      "Row2 Cell2",
      "Row2 Cell3",
      "Row2 Cell4"
    ],
    [
      "Row3 Cell1",
      "Row3 Cell2"
    ],
    [
      "Row4 Cell1",
      "Row4 Cell2",
      "Row4 Cell3"
    ],
    [
      "Row5 Cell1",
      "Row5 Cell2",
      "Row5 Cell3"
    ]
  ],
  "footers": [
    "Footer1",
    "Footer2"
  ]
}

Forms

The form message type allows for information to be gathered from the user during a conversation. Almost all elements that are allowed inside an HTML form are permitted here, with the exception of Fieldsets and Optgroups. To build a form, an array is passed in the elements key of the JSON (example below).

The following table contains all the possible elements types that can be added to a form. The control elements (submit and cancel) and at least one other element are required. All types can have an attributes field that is an object that contains the HTML attributes that will be assigned to the field, applicable examples in the table below. While the form is active the user input field is disabled and cannot be typed into. All fields which have the required attribute will have a * added to the end of their labels.

Once submitted or cancelled, the collected data (or none) will be sent to the Teneo Engine as a JSON, with an additional boolean field named success added to it. From the solution side you can parse the message received and use the success field to determine whether the form was sent or closed.

Engine JSON

The JSON that should be included in the teneowebclient output parameter looks as follows:

{
  "type": "form",
  "elements": [
    {
      "type": "title",
      "text": "Form Title"
    },
    {

Cards

The main elements of a card are the image, title, subtitle, and body. All elements are optional, but you should include at least one of them. Card images have a fixed height of 180px and look best when they have a ratio of 3x2.

Engine JSON

The JSON that should be included in the teneowebclient output parameter looks as follows:

{
    "type": "card",
    "image": {
        "image_url": "https://url.to/an/image.png",
        "alt": "This is an image"
    },
    "title": "This is the title",
    "subtitle": "This is the subtitle",
    "text": "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt."
}

In addition to the above, cards can contain a section with buttons, link buttons, or a clickable list.

    "type": "card",
    "image": {
        "image_url": "https://url.to/an/image.png",

Carousel message

You can group cards into a carousel type message.

The main content elements of a carousel are cards. A carousel can contain up to 10 cards inside of carousel_items.

Modal message

Modal messages appear on top of the chat window and block the user from interacting with the chat window until the modal is dismissed.

The main content elements of a modal are an image, a title, and a body. All elements are optional, but you should include at least one of them. Additionally, a modal can contain buttons. Modal images have a maximum height of 100px.

Engine JSON

{ 
    "type": "modal", 
    "image": { 
        "image_url": "https://url.to/an/image.png",
        "alt": "This is an image"
    }, 
    "title": "This is the title", 
    "text": "Lorem ipsum dolor sit amet, consectetur adipisicing elit.", 
    "button_items": [
        { 
            "style": "secondary", 
            "title": "Secondary", 
            "postback": "modal-secondary" 
        }, 
        { 
            "style": "danger", 
            "title": "Danger", 
            "postback": "modal-danger" 
        }
    ] 
}

Link Preview message

Link Previews can be used to display a little bit of information to the user about the page they are about to visit. This includes the page title, description, domain, and an image. Due to space limitations, descriptions are limited to 144 characters, but the full text will be made available as a tooltip.

Link Preview messages can be either generated manually using the JSON below, or they can be rendered automatically by giving the autoRedirect setting a false value. If you don't override the setting, it will default to true, and all links in the Output Hyperlink field of the Output nodes in Studio will automatically redirect the user to the URL defined there.

The data in the Link Preview is gathered from the meta tags of the target page. Due to CORS restrictions, the data from these tags has to be requested from the server side. In order to do so, please include this Groovy script in the Resources -> File area of Studio. Make sure to set the path to /script_lib.

Then under Globals -> Scripts -> Post-processing add the following line of code:

 if( _.outputURL){ _.outputURL= PreviewProperties.get( _.outputURL)}

In some cases, the target page doesn't have the necessary meta tags, in which case a localized message is displayed in place of the title or the description. You can learn how to modify this message in the Custom localizations page.

{
  "type": "linkpreview",
  "title": "Link title",
  "description": "Short text for the preview",
  "url": "https://example.com",
  "image": "https://url.to/an/image.png"
}

System message

Engine JSON

{         "type": "system",         "text": "This is a system message."     }

Combo message

You can combine multiple message types in a single bot response by using a 'combo' message.

The following message types can be included in a combo message:

• Buttons
• Cards
• Clickable lists
• Images
• Link buttons
• Quick replies
• Text messages
• Videos
• Audio players

You can include as many of these messages as you need in the order you like. Obviously one should take into account that the height of the chat window is limited; when too many messages are added, some of them may scroll out of view.

Engine JSON

The JSON used to create the combo message in the screenshot looks as follows:

{
    "type": "combo",
    "components": [
        {
            "type": "card",
            "image": {
                "image_url": "https://url.to/an/image.png",
                "alt": "This is an image"
            },
            "title": "This is the title",
            "subtitle": "This is the subtitle",
            "text": "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt."
        },
        {
            "type": "text",
            "text": "This is an additional speech bubble shown below the card."
        },
        {
            "type": "buttons",
            "title": "Are you sure?",
            "button_items": [
                {
                    "style": "danger",
                    "title": "Yes",
                    "postback": "Yes"
                },
                {
                    "style": "success",
                    "title": "No",
                    "postback": "No"
                }
            ]
        }
    ]
}

Splitting answers into 'bubbles'

Sometimes you may wish to provide an answer using multiple text bubbles.

This can be achieved by including an output parameter called outputTextSegmentIndexes. This output parameter should contain a list of index pairs, to indicate where the output text can be split into separate bubbles. The value of the outputTextSegmentIndexes should be structured like this (linebreaks are added for readability):

[
    [startIndexOfFirstBubble,endIndexOfFirstBubble],
    [startIndexOfSecondBubble,endIndexOfSecondBubble],
    ...
]

For the screenshot above, the following values were used:

Post-processing script

There are different ways to generate the value of outputTextSegmentIndexes. The Groovy script below is a global post-processing script that looks for two consecutive pipe symbols || in an output text, uses those to generate the value for outputTextSegmentIndexes, removes the pipe symbols from the answer text, and adds the outputTextSegmentIndexes output parameter.

def outputTextSegmentIndexes = []
def outputTextSegments = _.getOutputText().split(/\|\|/)
if (outputTextSegments.size() > 1) {
    def startIndex = 0
    def cleanedOutputText = ""

    outputTextSegments.each { textSegment ->
        def endIndex = startIndex + textSegment.size()
        if (textSegment) {
                outputTextSegmentIndexes << [startIndex, endIndex]
        }
        startIndex = endIndex
        cleanedOutputText += textSegment
    }
    _.setOutputText(cleanedOutputText)
}

if (outputTextSegmentIndexes) {
    _.putOutputParameter("outputTextSegmentIndexes", "${outputTextSegmentIndexes}")
}

To use the script, proceed as follows:

1. Copy the script above.
2. In Teneo Studio, open the 'SOLUTION' tab in the solution's window (if you're not there already).
3. Select 'Globals' in the purple bar on the left-hand side, and then select 'Scripts'.
4. Select 'Post-processing' and choose 'Edit'.
5. Paste the script above.
6. Click 'Save'.

Once added, whenever you add || to an answer text in Teneo Studio, the script will add the output parameter 'outputTextSegmentIndexes' with the proper index values and Teneo Web Chat will divide the text into multiple bubbles.

Javascript API

The functionality provided by Teneo Web Chat can be extended and modified using the Teneo Web Chat JavaScript API. This API allows developers to create extensions that can trigger events in the Teneo Web Chat widget, or subscribe to events that may occur in the chat widget. This lets developers change or extend its behavior in ways that are not provided by the standard configuration.

Extensions can be created using standard JavaScript, without needing to modify the source code of Teneo Web Chat. Full specification of the API can be found here: Teneo Web Chat JavaScript API.

Engine input parameters

Channel

In addition to the input entered by the user, requests to the Teneo Engine also contain an input parameter channel with value teneo-webchat. This allows you to change the behavior of your bot, depending on the channel used. For information on how to retrieve the value of an input parameter in Teneo Studio, see Store input parameters in the 'Build your bot' section.

Extra parameters

An optional map of parameters can be included when Teneo Web Chat is initialized. The keys in this map (and their values) will be included as individual input parameters in all requests to the Teneo Engine.

Cross-Origin Resource Sharing (CORS)

In many cases, the website that is hosting the webchat UI uses a different domain than the domain used by the Teneo Engine. Cross-Origin Resource Sharing (CORS) is a mechanism that uses additional HTTP headers to tell a browser to let a web application running at one origin (domain) have permission to access selected resources from a server at a different origin.

By default, the Teneo Engine includes CORS headers in the responses to browser requests coming from any domain. This means any site can add the webchat UI and interact with a Teneo Engine. If you want to restrict your solution to only include CORS headers for specific domains, you can add a file called tieapi_cors_origins.txt to the Teneo Resource Manager in the views folder. The file should contain the list of allowed origin domains (one domain per line: domains should include port numbers if applicable).
