Web Widget API

The Web Widget API is a JavaScript API for controlling the display and data passed to the Web Widget. The Web Widget embeds Zendesk functionality such as ticketing, live chat, and Help Center KB searches in a website.

The API consists of the following methods:

  • zE.setLocale
  • zE.identify
  • zE.hide
  • zE.show
  • zE.activate
  • zE.setHelpCenterSuggestions

You can use the zE.identify, zE.hide, zE.show, and zE.activate methods before and after page load. For example, you can use them in click event handlers.

Note: If you're looking for the Widget code for your pages, you can get it from the admin pages of your Zendesk Support account. After signing in to your Zendesk Support account, click the Admin icon (icon) in the sidebar and select Channels > Widget.

For more information on setting up the Web Widget, this support article will guide you through your setup.



The method takes a locale string as an argument. For a list of supported locales and associated codes, see https://support.zendesk.com/api/v2/rosetta/locales/public.json.

By default, the Web Widget is displayed to the end user in a language that matches the browser header of their web browser. If you want to force the Widget to be displayed in a specific language on your website, you can use zE.setLocale() to specify the language.

The following example displays the widget in German:

Note: This code should be placed immediately after the Web Widget code snippet

  zE(function() {




The method takes a JavaScript object with a name, email and optionally, organization property.

If you have access to your end user's name and email on the web page (for example, if your user is signed in), you can use zE.identify() to pass the details of that user to your Zendesk Support account, ensuring your user data is in sync.

Here's how it works: If the user's email doesn't already exist in your Zendesk Support account, a new user record with those details is created.

The Widget also uses the information in the zE.identify() call to pre-populate the contact or pre-chat chat form, saving the user from having to type in the information. This is especially useful for end users using your website on a mobile device (screenshot below).

Note: Passing an organization with zE.identify() only works for existing organizations in your Zendesk Support account. It does not create a new organization.

  zE(function() {
      name: 'John Citizen',
      email: 'john@example.com',
      organization: 'VIP'

The Widget contact form pre-populated using the data in zE.identify():




The method completely hides all parts of the Widget from the page. You can invoke it before or after page load.

Before page load

  zE(function() {

After page load

  <button onclick="zE.hide();">Hide Web Widget</button>



The method displays the Widget on the host page in its starting 'button' state.

For example, when someone logs into your website, you could call zE.show() to conditionally render the widget for authenticated users only:

  if(loggedIn) {
    zE(function() {

Note: The widget will be displayed by default on page load when the Web Widget code snippet is present. You do not need to call zE.show() to display the widget unless zE.hide() is used.



The method activates and opens the Widget in its starting state. The starting state will depend on how you configured the Widget on the Widget admin page.

For example, when someone clicks a 'Contact' button of your website, you could call zE.activate() to pop open the widget:


options object - hideOnClose: If true, hides the widget after the user closes it, false by default


  <button onclick="zE.activate();">Contact Us</button>

With Options

  <button onclick="zE.activate({hideOnClose: true});">Contact Us</button>

Note: Calling zE.activate() will also display the widget if it is hidden, you do not need to call zE.show() to use zE.activate().



The method enhances the contextual help provided by the Web Widget.

  • zE.setHelpCenterSuggestions({ url: true }) - In single-page apps, sets the query parameters in the URL as search terms without requiring the end user to refresh the page. This function should be called each time you want to set the suggestions. For example, navigating on a single-page app.

  • zE.setHelpCenterSuggestions({ search: 'search string' }) - Searches the Help Center for the specified search string. If results are found, displays the results as top suggestions when users click the Web Widget.

  • zE.setHelpCenterSuggestions({ labels: ['label1'] }) - For Guide Professional customers who use Help Center labels, searches the Help Center for articles with the given labels. If results are found, displays the results as top suggestions when users click the Web Widget.

Note: If you pass both search strings and labels, the labels are ignored.


Add the method in your HTML source code immediately after your Web Widget code snippet. Example:

zE(function() {
  zE.setHelpCenterSuggestions({ search: 'credit card' });

The zE.setHelpCenterSuggestions() method can be called multiple times, which can be useful in a single-page application.
