Livechat Widget API

The Livechat Widget API allows developers to integrate Livechat widget functionalities into their apps seamlessly. The code must be after the Livechat Widget installation script and wrapped as a callback of RocketChat(); function.
You can call multiple Livechat Widget APIs on the same page.

Methods

Set custom field

To set a custom field for a visitor, you can use the following:
RocketChat(function() {
this.setCustomField('fieldName1', 'Any value you want to store');
this.setCustomField('fieldName2', 'A value set just once', false); // you can pass false as the third parameter to not overwrite an already set value
});

Set theme options

To change the color of the online status on the Livechat widget, use the following:
RocketChat(function() {
this.setTheme({
color: '#04436A', // widget title background color
fontColor: '#FFFFFF', // widget title font color
iconColor: '#1d74f5', // widget icon color
title: "Welcome to Rocket.Chat", // default widget title when the status of service is online
offlineTitle: "Service is offline", // default widget title when the status of service is online
});
});

Assign chats to a specific department

To automatically assign a Livechat widget to a specific department (for example, to use a unique Livechat widget on more than one website), use the following :
RocketChat(function() {
this.setDepartment('FILL HERE DEPARTMENT NAME - case sensitive');
});

Set visitor token

To set an external token for a visitor, use this:
RocketChat(function() {
this.setGuestToken('FHwaLnp8fzjMupSAj');
});

Set name field

To set the visitor name field, use this:
RocketChat(function() {
this.setGuestName('visitor name');
});

Set email field

To set the visitor email field, use this:
RocketChat(function() {
this.setGuestEmail('[email protected]');
});

Register visitor

To register the visitor without using the registration form, use this:
RocketChat(function() {
this.registerGuest({
token: 'FHwaLnp8fzjMupSAj', // The token field is not required. If it is not passed, a new token will be generated
name: 'visitor Name',
department: 'my_department', // The department field is not required,
customFields: [ // The customFields field is not required. If it is passed it needs to be an Array, where each item needs to be an object with key and value fields
{key: 'my_custom_field_a', value: 'my_custom_field_a_value', overwrite: true},
{key: 'my_custom_field_b', value: 'my_custom_field_b_value', overwrite: true}
]
});
});

Set Language for Widget

To select a language for the widget, use this:
RocketChat(function() {
this.setLanguage('af');
});
See supported languages here.

Set a default Agent before starting a new conversation

Set a specific agent before the conversation starts. Use this to set up:
RocketChat(function() {
this.setAgent({
_id: 'h24yNtyoCmvp96wgt',
username: 'rocket.chat',
});
});

Initialize the widget by configuring all available properties in just one call

To configure all the settings in just one method, use this:
RocketChat(function() {
this.initialize({
theme: {
color: '#04436A',
fontColor: '#FFFFFF',
iconColor: '#1d74f5',
title: "Welcome to Rocket.Chat",
offlineTitle: "Service is offline",
},
department: 'sales',
guestToken: 'FHwaLnp8fzjMupSAj',
language: 'en',
});
});

Change widget visibility

You can either hide or show widget in your application. To hide the widget use this:
RocketChat(function() {
this.hideWidget();
});
To show widget, use this:.
RocketChat(function() {
this.showWidget();
});

Change the widget window state

You can either open or close the widget on your website. To open the widget by default, use this:
RocketChat(function() {
this.maximizeWidget();
});
To close the widget, use this:
RocketChat(function() {
this.minimizeWidget();
});

Set Business Unit to filter departments on Registration page

Assign a business unit to a widget instance so that the widget will only allow the visitors to select departments connected to that particular business unit on the widget's registration form.
Enterprises need to deal with hundreds of business units in the same workspace, and each Business Unit represents a specific website where Live Chat is installed. Therefore, once a BU is set, only departments associated with the current BU set should be available on the Live Chat Registration Form.
RocketChat(function() {
this.setBusinessUnit('LnM2rzbknjYSkkd5p');
});
To clear any connected business unit on the widget, use this:
RocketChat(function() {
this.clearBusinessUnit();
});
