After the administrator completes initial configuration of the components in the Web Widget from the Zendesk Support interface and works with their developer to add the Web Widget to their website, they can work with their developer to further customize the Web Widget, if desired.
This article is an overview for administrators about what advanced customizations are possible with the Web Widget. This article is meant to answer the question, "what else can I do with my Web Widget?" It explains the customization process for administrators, and also points to developer documentation that web developers need in order to do the work.
If you’re a web developer (or an administrator who is comfortable doing website development on your own) and are looking for complete documentation about the API settings and commands described in this article, or additional code samples, see the developer documentation for the Web Widget API instead.

Planning for Web Widget customizations
Most Support administrators aren’t web developers and work with someone else to implement customizations to the Web Widget. They don’t customize the Web Widget and websites on their own. They work with a web developer at their company, or an outside developer that they use on a contract basis to implement the changes.
The web developer is the person who does the customization work, and they do it by adding some code (the Web Widget API) to the HTML of the website. However, the administrator still has a role to play in the work. They need to understand what customizations are possible for the Web Widget, and tell the web developer what they want.
Some administrators have experience with HTML and choose to do the customization work themselves, acting as their own developer, and that's fine. Either way, customizing the Web Widget is actually a process for the administrator that requires some planning and involves these steps:
- Review the information in this article to understand what advanced customizations are possible.
- Meet with key stakeholders at your company to create a list of requirements for your Web Widget. What colors do want to use? How do you want the Web Widget to behave?
- Prepare a list of the customizations you want. Be as specific as possible and include links to API documentation that your web developer can reference.
- Give the list to your web developer, who will customize the Web Widget by modifying the HTML of your website.
Navigating the Web Widget API documentation
Here’s some important information to help developers navigate the Web Widget API documentation on the Zendesk developer site.
Updated, organized developer docs and API syntax— The Web Widget API syntax has changed, and we’ve also reorganized the Web Widget API developer documentation to make it easier to find the command or setting you’re looking for. The documentation is now organized by product channel (Help Center, Tickets, Chat and Talk) or by core settings and commands. For more information, see the developer documentation for the Web Widget API.
New Chat APIs—For information about how the old Chat (Zopim) APIs map to the new Web Widget APIs, see Migrating from the Chat Widget syntax to the unified Web Widget syntax.
Displaying the widget in a different language
By default, the Web Widget embedded in a website displays text in the end user’s language, based on the language of their browser. For example, if the end user's browser language is set to de for German, the widget will appear in German for that user. If the widget is embedded in a Help Center, it displays text based on the Help Center language setting.
The Web Widget supports a subset of Zendesk's supported languages. If the end-user's browser language is not supported by the Web Widget, the widget defaults to English. If the widget is unable to obtain the language from the end-user’s browser, the widget defaults to the language specified in Zendesk Support.
You can customize the widget so that it always appears in a specific language using the setLocale command. This command sets the language for only the widget and doesn't override your host page’s language.
For more information, see the developer documentation for the setLocale command.
Prefill forms with user contact information
You can save visitors to your site a few seconds and some annoyance or frustration by prefilling their name, email address, and phone number into contact forms. This includes ticket forms, pre-chat forms, and Chat offline forms. Use the identify and prefill settings.
You can also set user information to be read-only using the prefill setting, which is nice because you can avoid having duplicate user accounts in Support for the same person.
For more information, see the developer documentation for the identify and prefill settings.
Disabling ticket attachments
If you have enabled attachments for your tickets, users can attach files to tickets submitted from the Web Widget, by default. However, you can disable this option, if needed.
For more information, see the developer documentation for the attachments setting of the contactForm object.
Re-positioning the widget
The default position for the Web Widget is the bottom-right of the browser; when a user clicks on the Web Widget, it opens by expanding upward.
You can select a location for the Web Widget that varies from page to page (placing it on the left or right side of the page, or moving it to the top of the page where it expands downward when clicked). Use the position setting to position the Web Widget in the top-left, top-right, bottom-left, or bottom-right of the page.
For more information, see the developer documentation about the position setting.
Offsetting the widget placement
You can use the offset setting to reposition the Web Widget on your desktop or mobile devices. Use the initial position setting as the point of reference, and then use the offset setting to move the Web Widget horizontally, vertically, or both from that position (in pixels).
For more information, see the developer documentation for the offset setting.
Customizing the color of the widget elements
You can specify an overall color scheme for the Web Widget (theme color) and a custom color for the text in the launcher, contact button, and header (theme text color) from the Web Widget administration page (see Configuring components in the Web Widget).
However, if you want to customize specific elements, you need to use the color setting. You can choose a unique color for each of these Web Widget components:
- Launcher
- Button
- Button text
- Results list
- Header
- Article links
For accessibility purposes, the Web Widget automatically adjusts colors using an algorithm to guarantee a minimum contrast ratio as specified by the WCAG guidelines.
For more information about customizing the color of Web Widget elements, see the developer documentation for the color setting.
Changing visible ordering in the widget
Suppressing widget features on specific pages
You can enable the Contact Form, Chat, Talk, and Help Center in the Web Widget and then use the suppress setting to change the features offered on particular pages of your site to suit your needs.
- Have Help Center deflection on some pages
- Have Chat or the Contact Form without deflection on other pages
- Offer tiered service levels to signed in and identified users
For more information, see the developer documentation for the suppress setting.
Customizing widget text
You can change the text of the Web Widget components in the table below, and you can also customize the Help Center search placeholder text.
Component | Details |
---|---|
![]() |
Object: launcher Setting: chatLabel Description: Text on the launcher button when Chat is enabled and Help Center is not onDefault text: Chat |
![]() |
Object: launcher Setting: label Description: Text on the launcher button Default text: Help, Support or Feedback (defined on the Web Widget Admin page) |
![]() |
Object: helpCenter Setting: title Description: The title of the Help Center page Default text: Help |
![]() |
Object: contactForm Setting: title Description: Title of the contact formDefault text: Leave us a message or Contact us (defined on the Web Widget Admin page) |
![]() |
Object: helpCenter Setting: messageButton Description: Text on the button in the Help Center form that loads the Contact form (~20 character limit) Default text: Leave us a message or Contact us (defined on the Web Widget Admin page) |
![]() |
Object: helpCenter Setting: chatButton Description: Text on the button shown in the Help Center form that loads the Chat (~20 character limit)Default text: Help, Support, or Feedback (defined on the Web Widget Admin page) |
You use the translations object to change some of the default text displayed in the Web Widget. Translations are grouped by feature—for example, Launcher, Help Center, and Contact Form.
You can explore a list of potential language codes in Language codes for Zendesk supported languages.
The locale translations are triggered by the end user's browser language. You can also force the widget to always appear in a specific language and override the end-user's browser language setting. For more information, see Displaying your widget in a different language.
Adding a subject line to the contact form
With the subject setting on the contactForm object, you can set the Web Widget to include a subject field in the default contact form.
The default contact form is designed to promote engagement and offer a streamlined user experience when completing the contact form. While the default contact form does not include a subject line, you may want to add one to enhance the support experience for some customers.
For more information, see the developer documentation for the subject setting on the contactForm object.
Hiding the "View Original Article" button
The View Original Article button bridges the article in the Web Widget and the article in the Help Center itself. You can hide this button by using the helpCenter object, and setting the originalArticleButton property to false.
For more information, see the developer documentation for the originalArticleButton setting for the helpCenter object.
Limiting search results
With the filter setting on the helpCenter object, you can limit the results of searches performed from the Web Widget to articles based on category, section, and labels. For more information, see the developer documentation for the filter setting.
Scroll down for some additional examples that are not included in the developer docs that illustrate some of the ways you can limit search results.
To limit search to a specific section:
<script type="text/JavaScript">
window.zESettings = {
webWidget: {
helpCenter: {
filter: {
section: '200154474-Announcements'
}
}
}
};
</script>
To limit search to a specific category:
<script type="text/JavaScript">
window.zESettings = {
webWidget: {
helpCenter: {
filter: {
category: '200053794-General'
}
}
}
};
</script>
To limit search to content in multiple categories:
<script type="text/JavaScript">
window.zESettings = {
webWidget: {
helpCenter: {
filter: {
category: '115000669485,201742209'
}
}
}
};
</script>
To limit search to content with a specific label:
<script type="text/JavaScript">
window.zESettings = {
webWidget: {
helpCenter: {
filter: {
label_names: 'orders'
}
}
}
};
</script>
To limit search to content in a specific category and with specific labels:
<script type="text/JavaScript">
window.zESettings = {
webWidget: {
helpCenter: {
filter: {
category: '200053794-General',
label_names: 'Label One,Label Two,Label Three'
}
}
}
};
</script>
Customizing the Help Center search placeholder text
The default placeholder text in the Help Center search box is How can we help? You can customize this text so that it matches the user’s language, or so that specific text appears in certain languages. For more information, see the developer documentation for the searchPlaceholder setting.

If Contextual Help is enabled, you can also configure the Web Widget to open to recommended articles, making it easier for your customers to self-serve. For more information, see the developer documentation for the setSuggestions command for the helpCenter object.
Advanced configuration of Talk in the Web Widget
You can create multiple configurations that define how Talk behaves in the Web Widget. With each configuration you can customize call routing and display options for Talk in the Web Widget, based on your needs and preferences.
-
The agent group that you want Web Widget callback requests to be routed to
-
The priority of Web Widget callback requests
-
Display Request a callback, Call us, or both of these options in the Web Widget
-
Display an estimated wait time in the Web Widget
If you have only created a single configuration of Talk in the Web Widget, this will automatically be the default configuration that displays in the Web Widget whenever Talk is available.
If you have created multiple configurations of Talk in the Web Widget, you can use the Talk nickname setting to target the desired configuration.
For more information, see the developer documentation for the talk object, the nickname setting, and Configuring Zendesk Talk settings for the Web Widget.
Advanced configuration of Chat in the Web Widget
If you are using the Web Widget integrated Chat experience, you can offer Zendesk Chat functions in the Web Widget so that visitors to your website can chat with agents, and send and receive files that might help with their problem. Agents can also send proactive messages to visitors, to see if they want or need any help.
For more information, see the developer documentation for the chat object.
For information about how the old Chat (Zopim) APIs map to the new Web Widget APIs, see Migrating from the Chat Widget syntax to the unified Web Widget syntax.
Offering end users multiple contact options
You can allow end users to choose a contact option. You may want to customize your website so that some pages allow end users to make a choice and others don’t. The exact behavior depends on whether Chat or Talk is configured for the Web Widget, and whether a chat agent is online. You can customize the default text of contact options, if needed.
Here's a list of the default text:
Contact option | Default text |
---|---|
Contact button | Contact us |
Chat label (with agent online) | Live chat |
Chat label (with agent offline | Chat is unavailable |
Contact form label | Leave us a message |
For more information, see the developer documentation for the contactOptions setting.
Offering contact options with Chat
If Chat is configured for the Web Widget, end users are automatically routed to a chat, if a chat agent is available. However, you can allow end users to choose between chatting with an agent or completing a contact form, even if a chat agent is available. If a chat agent is available when the user clicks the launcher, but the agent signs off before the chat begins, the end users may see a message indicating that the agent is not available.
It's a known issue that when end users choose to chat, they cannot use the back button to return to the other contact options. To do so, they need to completely end the chat or refresh the page.
Offering contact options with Talk
If Talk and other contact options are enabled in the Web Widget, and agents are online, contact options are automatically enabled.
Formatting code for multiple widget components
Items that are specific to the Contact Form, Help Center, and Zendesk Chat are nested under those headings (contactForm, helpCenter and chat) in the HTML of your site, while global items are included separately.
- The position of the Web Widget on the screen has been changed using the offset setting. Offset is a global item, which is why it has its own entry.
- Help Center search—doesn’t include the View Original Article button. The title “Search for help” for English-language users, and “Have your say” for all other languages.
- Chat is disabled.
- The contact form title is “Message us” in English and “Contact us” in other languages.
- The launcher button text is “Make a request” in English and “Get help” in other languages.
<script type="text/JavaScript">
window.zESettings = {
webWidget: {
offset: { horizontal: '400px', vertical: '400px' },
helpCenter: {
originalArticleButton: false,
title: {
'en-US': 'Search for help',
'*': 'Have your say'
}
},
chat: {
suppress: true
},
contactForm: {
title: {
'en-US': 'SMessage us',
'*': 'Contact us'
}
},
launcher: {
label: {
'en-US': 'Make a request',
'*': 'Get help'
}
}
}
};
</script>

is there a way to customize the size of the chat on a tablet. We have a 15" tablet and we are using the Zendesk chat widget and when opened, the chat box takes up the whole tablet. How can we resize this on mobile?
Hi Mongkon BBN,
I have created a ticket on your behalf to discuss this in more detail. I am not entirely sure what you are referring to when you say docked type, so we will be able to get into more detail via ticket.
Thanks!
The widget is taking about 4 seconds to "activate" and expand. Is it possible to activate it immediately?
Are there any plans to allow for the addition of notes, comments, or non-visible ticket fields to the widget to allow for the passing of customer data that the customer doesn't necessarily need to see? We would like to attach customer specific information from our app to the ticket without confusing the user by showing it to them in the widget.
Hello Chris,
No plans have been made to add this functionality at this time. I completely understand your use case though and how that can be useful. I'll submit your feedback to our product team on your behalf but i'd also encourage you to post this to our Product Feedback Forum. On that page other users can up-vote your idea and it can help our product team weigh the popularity and demand of new feature requests because of the interaction it allows with other customers seeking similar functionality.
I apologize i don't have better news right now but hopefully this functionality can be implemented in future updates.
Im having trouble with implementing labels with the web widget.
this is how the web widget is implemented:
1. Zendesk widget is implemented with google tag manager
2. A label is triggered when viewing a certain page
what are the issues:
suggestions don't show up in the widget, but I know that the label was triggered.
If in chrome I use Incognito mode, everything works fine!
you can see my setup in this test page where you can also see the code used.

Is there a way to customize your "Top results" and show only certain articles?
Hi Marisa,
Yes. You can use Contextual help to surface results immediately after clicking the web widget, and you can use the API to pick the content you want to surface.
We use a very simple way to control which results surface with the opening of the widget, we use the label default_result on the articles we want featured, and use the following customization to the web widget script:
This lets us add and remove the articles we want featured. There are other ways to go about this for other scenarios in the API docs.
Hope that answers your question, let me know if anything is unclear.
Is there a way via code to change the label for the Subject and Description field. I am currently using the webwidget and custom forms, so I would only want to change the label on one particular form. If that is not possible, is it possible to default and hide the description field entirely on the form using the webwidget so that I can use a custom field instead.
Is there a way to change the launcher label when Talk is enabled?
Similar to chatLabelOnline, is there a talkLabel to change "Call us Back" or "Call us" labeltext?
Hi Thomas,
Unfortunately at this time that launcher label is not customizable for when Talk is enabled, it's a bit too new at this time. However our team is open to feedback for what sorts of customization options you'd like to customize that label instead as our team further discusses potential future options!
I required only web Widget Script On-demand Loading.
Currently when the visitor opens our web-page, the Help Web Widget code will start to load, and i want to disable that.
And make it load only when the Help button is clicked is this possible ?
Hi everyone,
We're in the final stages of adding the Web Widget to our application and have spotted what we expect to be a change in behaviour. When we first started experimenting, we found that the "View Original Article" button was appearing in the top-right hand corner of the Web Widget. Based on documentation, it sounds like this is the default, and it can be optionally suppressed .
Recently, we've spotted that the 'View Original Article" button is no longer showing, though we haven't made any configuration changes. We've even tried explicitly setting the parameter to true, but this hasn't worked, either:
Is anyone else experiencing / able to reproduce this issue and perhaps able to offer an explanation or solution? We'd really like our customers to be able to view our Guide articles in full-screen, especially when the article contains screenshots.
Thanks in advance for any help!

Hi Sushil,
To have the widget script load only upon clicking the button, you just have to insert this to your html:
Just replace <key> with your own widget key. We can't guarantee that it will work on your account, but we tested this and it worked on a test account.
Hope this helps. Thanks Sushil!
Good Day
Can I modify the web widget search to search a specific website
You can specify which section or category it displays from your Help Center.
Not external websites.
How can I change the font size of Ticket Form titles in the web widget? Our titles are a bit long and cut off within the widget at the moment.
Hi Justin,
That's a great question. I can definitely see your use case here. Unfortunately, that's not something you can change. There's no customization for text size in the User Interface or the Web Widget API.
Hope that helps clarify a bit!
Hi there,
It looks like restricted articles (i.e. articles only visible to signed-in users) don't showing up in my web widget, even if the user is signed-in?
Am I missing a step?
Thanks!
Rich
That's correct, Rich!
You may follow the directions here to show these restricted articles in the widget:
Using restricted Help Center content with the Web Widget
The article states two things that happen when you configure the Web Widget to include restricted content:
Hope this helps!
Hello - is there any way to add custom CSS to the web widget. I am hoping to add the zendesk web widget (the help widget) on my wix website. I am able to add the button in an iframe (that seems to be the only option on wix). However, the button is not pinned, so it scrolls off of the viewport.
Is there a way to set the CSS position absolute to the web widget?
Hi Ash D, we don't support custom CSS. If you've wrapped the web widget in another iframe it will be positioned within that iframe instead of the page window.
Hello, we can't find the option to activate the 'view more' button in the web widget. Can someone please help?
As far as I know the view more option when searching for Guide articles is gone. It'll only show the best 10 results now in the list based on prior user actions (how many people read an article, create a follow up ticket,...)
Kristof,
Thomas is correct, we removed that button feature early 2018 to lessen the number of clicks for users to navigate the widget.
When setting 'Theme color' of widget to white (ffffff) the 'view original article' button is also colored in white, and therefore invisible. Is there a way to fix or workaround this issue?
Thanks
Hi Yair,
My thoughts are that you could edit the originalArticleButton object specifically and change the color of it? According to the color editing options you ought to be able to set a unique color for the 'button' element.
Thanks,
Hi, is it possible to reorder the contact options that are displayed in the web widget? I have call us, live chat and quick message options but I want to make sure live chat is the 1st option. Currently it’s call us on top
Thanks
Is the documentation here correct RE filtering by label?
In the api docs it says the property should be 'label' but here it is 'label_names'.
We are thinking of implementing web widget. However, our portal is open to anyone. We would like to do the following:
if a customer goes to type into the web widget, that it asks the user to login with their portal account. This way if the user creates a ticket, that they are not just any user. They must be a registered customer to do this.
Is there a way to do this? And how?
