Webchat Developers Reference


Symbee Connect Webchat provides a quick and easy way of enabling the Webchat channel within your Contact Center. Webchat endpoints, or “Instances” can be configured within the Symbee Connect Administration Portal that provide a configurable (and 100% customizable if needed) customer-facing Webchat front-end for use in your website.

Symbee Connect customer-facing Webchat endpoints can be used with either Amazon Connect Chat or Symbee Connect Chat. Initially they were developed to run over the Symbee Connect Webchat engine (prior to Amazon Connect offering a chat engine). Once the Amazon Connect Chat engine became available, Symbee Connect Webchat endpoints were also integrated into Amazon Connect Chat, and therefore can be configured to run over either engine (Symbee Connect delivered, or Amazon delivered), and are 100% compatible with both.

Each configured customer-facing Webchat endpoint is a logical container made up of:

This document provides reference details for Administrators and/or Developers configuring your customer-facing Webchat endpoints and integrating them into your customer or user facing website(s).

Configuring a new customer-facing Webchat Endpoint

Within your Symbee Connect account you can configure multiple Environments if you have multiple Amazon Connect instances. Customer-facing Webchat endpoints are configured on a per-environment basis.

  1. Log into the Symbee Connect Administration Portal.

  2. From the home page after login, ensure you have selected the appropriate Environment in the top navigation bar.

  3. From the Function Menu, select WebChat Administration from the Channel Configuration section.

  4. From the resulting WebChat Instances page, click the Add Webchat Instance button.

  5. Complete the Add WebChat Instance dialog, supplying a new Instance Code and descriptive name for your new Webchat endpoint, and click Add… (note: the value you enter for your Instance Code becomes part or the unique WebChat URL)

  1. Once the basic new WebChat Instance is created, and it appears in your list of WebChat Instances, click the new instance to progress to the Maintain Webchat Instance Settings page to configure the details of your new Webchat endpoint. See Configuring the setting of your customer facing Webchat Endpoint for details.

Configuring the setting of your customer facing Webchat Endpoint

All the settings discussed in this section are located on the *Maintain Webchat Instance Settings* page within the Symbee Connect Administration Portal. Refer to the previous section for how to access this page.

Most settings in the WebChat Instance Settings view have self-explanatory descriptions. This section of the document covers some of the general concepts, and common questions.

WebChat Routing

Use the Deliver Provider, Default Queue List, and/or Amazon Chat Flow settings in the Integration Settings section to control how incoming webchats get handled and routed.

If the Deliver Provider is set to Symbee Connect, the value of the Default Queue List determines which Symbee Connect Skill Queue incoming webchat conversations will be queued into. Multiple Webchat Instances can be configured to use the same Skill Queue, or different Skill Queues can be configured for each Webchat Instance.

If the Deliver Provider is set to Amazon, use the Amazon Chat Flow setting to select which Amazon Connect Contact Flow new incoming webchat conversations will first be handled by. In this case, what queue the webchat ultimately gets routed to is a product of the Contact Flow (or Flows) and is therefore not selected in Symbee Connect.

General UI Setup

Under the Chat Client UI Customization section, always select Customer UI Version: Version 2.

In the same section are checkboxes for optionally enabling the most common fields often used in the Pre-Chat Questionnaire – Email, Phone, and Initial Question. The user or customers Name is mandatory and therefore no checkbox is provided for this, however you can use the Name Field setting under the Additional Customer Form Items section to control whether the name is prompted for using a single Full Name field, or separate First and Last name fields.

Localization and Language

All the textual labels used within the Webchat customer-facing UI are configurable, including menu labels, and text on the menu-driven action forms. The Canned Messages and localization section lists each of these strings with default values you can update as needed.

If you need to provide a Webchat endpoint for multiple different languages, configure a separate Webchat Instance for each language, and translate each of the strings in the Canned Messages and localization section to the target language required.

The customizable logo is displayed in the header on the top of the Pre-Chat Questionnaire Form and at the top of the main chat conversation view. When uploading your logo (via the Logo field in the Chat Client UI Customization section), for best results your logo should have the following characteristics:

  1. The image type needs to be either PNG or JPEG (JPG)

  2. Have a Transparent background

A note about Logo image size: The size expected in the default CSS to avoid scaling is: 36 pixels in height, with a width not greater than 200 pixels. However, the size and proportions of each Company or Associations Logo vary widely. To have your Logo presented exactly how you want it, you may need to override the default CSS settings for how the Logo is displayed. This is expected. Refer to Adjusting Layout, Fonts, Colors and Sizing and Example CSS Override File for further details on how to do this.

Adjusting Layout, Fonts, Colors and Sizing

You can choose to customize the look of your customer-facing WebChat experience as much or as little as you wish. Within the Chat Client UI Customization section, the Custom CSS file location setting allows you to provide an overriding CSS file to customize the display to meet your requirements (for example, use your corporate colors, fonts, and a layout that is in-line with the wider website your chat will be embedded in).

Specifying a custom CSS file is optional. If supplied, the specified CSS link is included last in the WebChat HTML document, meaning you can override anything in the UI you need.

You can also configure the same custom CSS file to be used by multiple/many WebChat Instances, so all your different WebChat endpoints have a similar look and layout.

Notes about hosting your custom CSS File: The value entered for the CSS file location needs to be a well-formed URL (and should be HTTPS) – this URL is used in the HTML document to fetch your custom CSS on page load. Therefore, you need to host your custom CSS file on a webserver of some sort (i.e. it needs to be accessible via HTTP protocol).

Refer to dix A – Example CSS Override file for example starter CSS file contents.

Configuring the Pre-Chat Questionnaire Form - Standard Fields

On the Pre-Chat Questionnaire Form, there a four standard fields that can be optionally enabled or configured using settings under the Chat Client UI Customization section:

And the Additional Customer Form Items group:

When enabled, the fields displayed in the form are as follows (these field names can be used to pre-populate values – see section 4.4).

firstName If the Name Field setting is set to “First and Last fields”, this field contains the customer’s first name.
lastName If the Name Field setting is set to “First and Last fields”, this field contains the customer’s last name.
fullName If the Name Field setting is set to “Full name field”, this field contains the customer’s name.
mainEmail If Display Email Field is checked, this field contains the customer’s email address.
mainPhone If Display Phone Field is checked, this field contains the customer’s phone number.
initialQuestion If Display Initial Question Field is checked, this field contains the customer’s reason for initiating the webchat.

Configuring the Pre-Chat Questionnaire Form - Custom Forms

Up to five custom Pre-Chat Questionnaire Form items may be configured in the Additional Customer Form Items group.

Each custom item is controlled with 4 settings: Name, Label, Type, and Required.

Form Item Decription
Form Item 1 - 5 Name A name for the custom field. This is the name that will be passed to the agent in the Pre-Chat Survey bubble. (This name can also be used for pre-populating the form. See Section 4.4) The Name may contain letters and numbers, and spaces or the # character; however, all other special characters should be avoided.
Form Item 1 - 5 Name A label for the custom field. The label displayed to the customer next to the entry for the field.
Form Item 1 - 5 Type A type for the custom field. The following available values are currently supported: String, Number, Phone, Email

This value will be used to validate the customer’s entry of the field.
Form Item 1 - 5 Required Whether this custom field must be provided by the customer before the chat conversation can be started.

Integrating a Webchat Endpoint into your website

Webchat Endpoint Access URL

Each Webchat endpoint has a unique URL used to launch it. This URL can be found on the Maintain WebChat Instance Settings page under Usage and Developer Details and is titled Chat Client Address.

Presenting the Customer-facing Webchat to users

Should you present your Webchat as a Pop-out or should it be embedded?

How you present the WebChat experience to your users is up to you, but fundamentally takes one of two approaches. Both approaches usually start with some sort of new “Chat With Us” type button you add to your website. When the new Chat button is clicked, you then usually do one of the following – each has their positives and negatives:

  1. Present the Webchat window as a new “Pop Out” window.
    This is done by you performing some variant of a JavaScript window.open(<*Webchat access URL*>)command.

    The positives of this approach are it is very quick and simple to implement (usually 1 or 2 lines), and the window is “external” for the user so they can navigate around your website separate to the chat window. It also provides a more natural “separate window” experience on mobile devices (phones and tablets).

    The challenges are, more recent web-standards have limited your ability to “keep a window on top” so depending on the window location it may get hidden from the user in the background when they click on something else; and you may need to add additional messaging to your website to let the user know a pop-out window is expected, and to turn off or allow it in pop-up blockers.

    To address the 'window on top' issue when running chat as a pop out

    If you set the target attribute on the window.open(...) JavaScript request, to a static text literal - for example <company-name>-webchat rather than to "_blank", and then allow your "Chat with Us" button on your website to be clickable even when a chat is already in progress, the end result is the repeated window.open(...) request on a subsequent click of your "Chat with Us" button will cause a refresh of the existing chat window (which is supported - it simply repaints the conversation in progress), but notably will also bring the pop-out window back into focus, and therefore "to the front" again.

  2. Embed the Webchat window in-line in your website page.
    This is done by you creating an <iframe> with its “src” being the Webchat access URL.

    The positives of this approach are you can control the slide-in/slide-out style presentation of the chat, and you have 100% control of the chat being “visible” on your site.

    You may however need to provide an alternative presentation when your website is being used on a mobile device to be more natural. Additionally, you need to consider how your website is structured – is it a single page app (SPA) where you can home the <iframe> at the top level so it remains present when the user navigates from one place on your website to another? Or is it a multi-page website, where the user may start the chat on one-page, then continue the chat after navigating to another page? (ultimately a page and JavaScript context reload).

    The Symbee Connect Webchat frame 100% supports this type of deployment (if the frame is refreshed quickly from one page to another, it will preserve the conversation on its own), however you will need to consider, as the website developer, appropriate placement of the chat <iframe> on each page as a new page loads to keep the experience natural (e.g., knowing when to display the frame already visible on a subsequent page, versus just a Chat button, depending on if a conversation is already running).

    Make sure NOT to declare a hidden <iframe> statically in your page

    If you are taking the iframe approach, make sure to not declare the <iframe> in your main website HTML on page load (for example, hidden, "in preparation") - or if you do, at least don't set the src= attribute on the iframe element. As if you do, it causes an actual fetch of the webchat window/frame, which can cause a chat conversation to be started inadvertently on every visit of your web page/site even if the user hasn't clicked your chat button. Instead, dynamically add the <iframe> into the DOM (or set the src= attribute) only once the user genuinely clicks your "Chat with Us" button, as depending on how you configured your webchat, the conversation may start immediately.

Example JavaScript to create Pop-Out window

If following approach 1 above, the following is an example HTML and JavaScript snippet that could be used in your website to launch the chat window (substitute the URL below with your Webchat endpoint instance URL):

<div id=”chatButton” 
    onclick=”window.open(‘https://Symbee Connectconnect.com/Symbee Connect-connect-chatclient/chatClient/my-org/my-env/my-chat?fullName=John%20Black’, 
        ‘_blank’, ‘width=340,height=550’)”>
Chat with Us

See considerations for pop-up blockers in the next section.

Note: the link above also pre-populates the Full Name field (see section 3.6). For more information on pre-populating standard and custom fields see section 4.4.

Note: the height value of 550 pixels above is meant to work well when all Pre-Chat Questionnaire Standard Fields (see section 3.4) are enabled. If you are configuring custom fields the form may require additional vertical space. If there is not enough room provided for the full form, the page is configured to show a vertical scrollbar.

Pop-up Blocker Constraints

If you are presenting your Webchat by launching a new window from a website page (see section 4.2 above, Approach 1), you will need to consider and handle the pop-up blocker scenario.

There are many ways to detect in JavaScript if a window is being blocked within your page by adding more logic to the snippet within above (or break it out into its own JavaScript function) and then display an alert to the user that the chat is being blocked by their pop-up blocker. Web-developers are familiar with this. Some consideration needs to be taken to handle different browsers also (Chrome, Firefox, Safari, Edge, etc.) if this approach is taken.

An alternative simple, low-tech but reliable approach can also be to add a little line of text in small font below or above the web-chat link that reads something like:

(if the chat window doesn’t appear when clicking above, check your pop-up blocker to allow pop-ups from this site)

Pre-populating the Pre-Chat Questionnaire Form Fields

The Pre-Chat Questionnaire Form of the WebChat can be pre-populated by modifying your Webchat endpoint URL (see above).

Fields can be pre-populated by ding the item name and default value to the chat page URL query-string. Multiple fields can be populated. For example, ding the following to your Webchat endpoint URL will pre-populate the first and last name fields with Jane Doe:


See Configuring the Pre-chat-questionnaire-Form - Standard Fields for the names of Standard Fields and section 3.7 for determining the names of Custom Fields.

Proactively Determining if Chat is Open or Closed

The Symbee Connect Webchat Channel also exposes a simple HTTPS service endpoint that can be called internally from your website to proactively determine if a chat queue is open or closed. The response is a JSON string describing the current state of the requested queues. The intent of this service endpoint is to allow a web site integrating chat to optionally hide a “Chat With Us” button if the backing contact center Webchat queue is not open.

The endpoint URL can be found on the Maintain WebChat Instance Settings page under Usage and Developer Details and is titled Queue Status Endpoint.

An example queue status URL, asking for the current state of the support-chat queue:

Note that queue status URL endpoints only support POST requests, they do not support GET requests. This is for security purposes and is intentional.

Queue Checker Response Handling

First, verify the HTTP Status Code of the response (200 OK indicating success, anything else indicating failure).

If 200 OK, a JSON object is returned.

Queue Checker Response Example

Example successful JSON response returning requested queue statuses:

    "queueCode" : "my-chat",
    "queueName" : "support-chat",
    "queueStatus" : "Forced Open",
    "isOpen" : true,
    "statusDateTime" : "2019-04-01T16:59:58.355Z"

Queue Checker Notes regarding CORS (Cross Site Scripting / Cross Origin Resource Sharing)

Please consider web browser CORS (Cross Origin Resource Sharing) implementations and rules if you intend to make requests to the Queue Checker endpoint directly from JavaScript.

CORS related reference notes for the Queue Status endpoint:

content-type: text/plain

Webchat Endpoint Access Point

The following settings within the Maintain WebChat Instance Settings page can be used to restrict where and how your Webchat Endpoint can be presented:

Restrict to Frame Only

Enabling this setting stops your Webchat Instance access URL from being able to be generically opened as a top-level window in a browser. This means the URL cannot be simply copied and opened from anywhere and forces the usage of your Webchat endpoint to be as an embedded <iframe>. If you attempt to access the endpoint URL directly with this setting enabled, you will get Access Denied.

Restrict Hosting Domains

Forcing your Webchat endpoint to only be displayed within an <iframe> (see Restrict to Frame Only) inherently means it must be hosted in another web page.

You can then additionally use the Hosting Domains setting to further limit which domains the web page encapsulating the <iframe> can be served from.

For example, enabling Restrict WebChat to Frame only, and setting Hosting Domains to:


restricts your Webchat endpoint to only allow, when running in an <iframe> embedded in an html document served from the www.abccompany.com domain.

Restrict to Frame Only, but still present Webchat as a Pop-Out window

If you want to restrict access to a limited set of named domains, you will need to enable Restrict to Frame Only. However, doing this stops your Webchat endpoint being displayed as a top-level pop-out window.

If you still want to present your Webchat as a pop-out window, the solution is to create a very minimal HTML document, that simply encapsulates an<iframe>, expands the <iframe> to fill the complete window, and then host this minimal HTML document (web page) within the same webserver / domain as the outer website you are using your Webchat endpoint with.


You configure a new Symbee Connect Webchat endpoint, named “example-webchat”, in your-company, prod environment. The Webchat access URL is:

You have a website hosted either on your own servers, or through a hosting platform. Your website is served as the domain www.example.com. Your home URL might be https://www.example.com/index.html

You then create a new minimal HTML document, located at: https://www.example.com/chat.html

The chat.html document contains the following:

<!DOCTYPE html>
    <title>Example Chat</title>
    <style> html { height: 100%; } body { height: 100%; margin: 0; }</style>
    <iframe src="https://Symbee Connectconnect.com/Symbee Connect-connect-chatclient/chatClient/your-company/prod/example-webchat"
            style="width: 100%; height: 100%; border: none; overflow: hidden;"></iframe>

You add a “Chat with Us” <button> to you web site, and upon click, perform a JavaScript something like:


Then in your Symbee Connect WebChat Instance configuration, you set:

Example CSS Overide File

For a quick starter file, paste the contents of the below into a text file with a name ending in .css, host the file, and refer to its URL in the Custom CSS file location setting of the Chat Client UI Customization section. Refer to Adjusting Layout, Fonts, Colors and Sizing for further detail.
