Core settings and commands affect the entire messaging widget.

Parameters

None

Parameters

  • callback: Function.

Example

zE("messenger:on", "open", function () {  console.log(`You have opened the messaging Web Widget`)})

On Close

zE('messenger:on', 'close', callback<function>)

Executes a callback when the messaging Web Widget closes.

Parameters

Unread Messages

zE('messenger:on', 'unreadMessages', callback<function>)

Executes a callback when the number of unread messages changes.

Parameters

  • callback: Function. The callback is passed the current count<number> of unread messages when executed.

Example

zE("messenger:on", "unreadMessages", function (count) {  console.log(`You have ${count} unread message(s).`)})

Custom Launcher

To create a custom messaging Web Widget launcher and define how it behaves, use the open, close & unreadMessages API and launcher settings for Messaging in Admin Center.

Set locale

zE('messenger:set', 'locale', newLocale<string>)

Sets the locale of the messaging Web Widget. It overrides the messaging Web Widget's default behavior of matching the same language an end user has set in their web browser.

The command takes a locale string as an argument. For a list of supported locales and associated codes, use the following Zendesk public REST API endpoint: https://support.zendesk.com/api/v2/locales/public.json.

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

Parameters

  • newLocale: String. The locale string to change the locale to.

Example

zE("messenger:set", "locale", "es")

Set zIndex

zE('messenger:set', 'zIndex', newZIndex<number>);

Sets the CSS property z-index on all the iframes for the messaging Web Widget.

When two elements overlap, the z-index values of the elements determine which one covers the other. An element with a greater z-index value covers an element with a smaller one.

By default, all iframes in the messaging Web Widget have a z-index value of 999999.

Parameters

  • newZIndex: Number. The z-index value to use for all iframes for the messaging Web Widget

Example

zE("messenger:set", "zIndex", 123)

Set cookies

zE('messenger:set', 'cookies', isEnabled<boolean>);

The messaging Web Widget uses a mixture of cookies as well as local and session storage in order to function.

If the end user has opted out of cookies, you can use the command below to let the messaging Web Widget know that it is unable to use any of these storage options.

Currently, disabling cookies will result in the messaging Web Widget being hidden from the end user and all values in local and session storage being deleted.

Parameters

  • isEnabled: Boolean. If false, the messaging Web Widget will be hidden from view and all stored data will be deleted.

Example

zE("messenger:set", "cookies", false)

Set Conversation Fields

zE('messenger:set', 'conversationFields', conversationFields<{ id: <string>, value: <string|number|boolean> }[]>;

Allows values for conversation fields to be set in the client to add contextual data about the conversation. To learn more about Messaging Metadata, see Introduction to Messaging Metadata.

Conversation fields must first be created as custom ticket fields and configured to allow their values to be set by end users in Admin Center. To use conversation fields, see Using Messaging Metadata with the Zendesk Web Widget and SDKs.

Note: Conversation fields aren't immediately associated with a conversation when the API is called. It'll only be applied when end users start a conversation or send a message in an existing conversation from the page it's called from.

System ticket fields, such as the Priority field, are not supported.

Conversation fields are cleared when the authentication API to sign-out is called. The conversationFields API needs to be called again to apply field metadata to a fresh conversation.

Parameters

  • conversationFields: Array. Formatted as an array of objects with id and value properties.
Property Type Description
id string id of custom ticket field
value string, number or boolean value of custom ticket field

Example

For example, if the id of your custom field for order total is 123456789 and you want to set its value to 100.50, then you would call:

zE("messenger:set", "conversationFields", [  { id: "123456789", value: 100.50 }])

Set Conversation Tags

zE('messenger:set', 'conversationTags', conversationTags<string[]>);

Allows custom conversation tags to be set in the client to add contextual data about the conversation. To learn more about Messaging Metadata, see Introduction to Messaging Metadata.

Conversation tags do not need any prerequisite steps before the API can be used. To use conversation tags, see Using Messaging Metadata with the Zendesk Web Widget and SDKs.

Note: Conversation tags aren't immediately associated with a conversation when the API is called. It'll only be applied when end users start a conversation or send a message in an existing conversation from the page it's called from.

Conversation tags are cleared when the authentication API to sign-out is called. The conversationTags API needs to be called again to apply tag metadata to a fresh conversation.

Parameters

  • conversationTags: Array. Formatted as an array of strings.

Example

For example, to apply sales and computer_accessories tags to a sales conversation about computer accessories, then you would call:

zE("messenger:set", "conversationTags", ["sales", "computer_accessories"])
