Sending information to Chatwoot

Additional information about a contact is always useful. The Chatwoot Website SDK ensures that you can send additional information that you have about a user.

If you have installed our code on your website, the SDK would expose window.$chatwoot object.

In order to make sure that the SDK has been loaded completely, please make sure that you listen to chatwoot:ready event as follows:

window.addEventListener("chatwoot:ready", function () {
// Use window.$chatwoot here
// ...

If you would like to listen to the messages in the widget you can use the following event.

window.addEventListener("chatwoot:on-message", function (e) {
console.log("chatwoot:on-message", e.detail);

SDK settings

To hide the bubble, you can use the setting mentioned below.

Note: If you use this, then you’ll also have to trigger the widget.

window.chatwootSettings = {
hideMessageBubble: false,
position: "left", // This can be left or right
locale: "en", // Language to be set
useBrowserLanguage: false, // Set widget language from user's browser
baseDomain: ''
type: "standard", // [standard, expanded_bubble]
darkMode: "auto", // [light, auto]

Persist chat session across sub domains baseDomain Configuration,

The baseDomain config retains user chat sessions across sub-domains, ensuring a seamless chat experience as users navigate through your domain's pages.

Setting Up

Add the baseDomain configuration to window.chatwootSettings

window.chatwootSettings = {
//other settings
baseDomain: "",

Replace with your domain, keeping the preceding dot.


  • Ensure SSL is set for all sub-domains.
  • Configuration applies to sub-domains, not different domains.


baseDomain: ''

Use browser language in your live chat widget automatically

To show the live chat widget in the user's browser locale, set the useBrowserLanguage to true in the window.chatwootSettings mentioned above.

Note: If useBrowserLanguage is set to true, The locale mentioned will be ignored. If the browser language is not supported by chatwoot, the locale mentioned under locale will be used. If that's also missing, the widget will fall back to the locale of the agent dashboard.

Dark Mode

Chatwoot live-chat widget supports dark mode from v2.4.0. To enable the dark mode, follow the steps mentioned here.

Widget designs

Chatwoot supports two designs for the widget.

  1. Standard (default)


  1. Expanded bubble


If you are using expanded bubble, you can customize the text used in the bubble by setting launcherTitle parameter on chatwootSettings as described below.

window.chatwootSettings = {
type: "expanded_bubble",
launcherTitle: "Chat with us",

Enable popout window

In order to enable the popout window, add the following configuration to chatwootSettings. This option is disabled by default.

window.chatwootSettings = {
// ...Other Config
showPopoutButton: true,

You can also popout the chat window programatically with the `popoutChatWindow()` method.

Programatically open the popout window

You can open the popout window programatically with the popoutChatWindow() method.

To initiate this, call the method like below.


Toggle the widget bubble visibility

If you want to hide/show the Chatwoot widget bubble, you can do so with toggleBubbleVisibility('show/hide')


window.$chatwoot.toggleBubbleVisibility("show"); // to display the bubble
window.$chatwoot.toggleBubbleVisibility("hide"); // to hide the bubble

Trigger widget without displaying bubble


// Toggle widget by passing state
window.$chatwoot.toggle("open"); // To open widget
window.$chatwoot.toggle("close"); // To close widget

Set the user in the widget

window.$chatwoot.setUser("<unique-identifier-key-of-the-user>", {
email: "<>",
name: "<name-of-the-user>",
avatar_url: "<avatar-url-of-the-user>",
phone_number: "<phone-number-of-the-user>",

setUser accepts an identifier which can be a user_id in your database or any unique parameter which represents a user. You can pass email, name, avatar_url, phone_number as params. Support for additional parameters is in progress.

Make sure that you reset the session when the user logs out of your app.

Reset the session (use this while you logout the user from your app)


Identity validation using HMAC

To disallow impersonation and to keep the conversation with your customers private, we recommend setting up the identity validation in Chatwoot. Identity validation is enabled by generating an HMAC(hash based message authentication code) based on the identifier attribute, using SHA256. Along with the identifier you can pass identifier_hash also as shown below to make sure that the user is correct one.

window.$chatwoot.setUser(`<unique-identifier-key-of-the-user>`, {
name: "", // Name of the user
avatar_url: "", // Avatar URL
email: "", // Email of the user
identifier_hash: "", // Identifier Hash generated based on the webwidget hmac_token
phone_number: "", // Phone Number of the user
description: "", // description about the user
country_code: "", // Two letter country code
city: "", // City of the user
company_name: "", // company name
social_profiles: {
twitter: "", // Twitter user name
linkedin: "", // LinkedIn user name
facebook: "", // Facebook user name
github: "", // Github user name

To generate HMAC, read identity validation

Note that implementing HMAC authentication will allow chat history to persist across sessions.

Set custom attributes
