Livechat Widget API

Usage

Livechat Widget API code must be inserted 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 code:

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 online color of the Livechat widget, use the following code:

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 code:

RocketChat(function() {
    this.setDepartment('FILL HERE DEPARTMENT NAME - case sensitive');
});

Set visitor token

To set an external token for a visitor, you can use the following code:

RocketChat(function() {
    this.setGuestToken('FHwaLnp8fzjMupSAj');
});

Set name field

To set the visitor name field, you can use the following code:

RocketChat(function() {
    this.setGuestName('visitor name');
});

Set email field

To set the visitor email field, you can use the following code:

RocketChat(function() {
    this.setGuestEmail('sample@rocket.chat');
});

Register visitor

To register the visitor without using the registration form, you can use the following code:

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',
        email: 'sample@rocket.chat',
        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'},
            {key:  'my_custom_field_b', value: 'my_custom_field_b_value'}
        ]
    });
});

  });
});

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

The widget allows configuring all the settings in just one method, the following properties are acceptable:

RocketChat(function() {
    this.initialize({
        theme: {
            color: '#04436A',

            iconColor: '#1d74f5',
            title: "Welcome to Rocket.Chat",
           offlineTitle: "Service is offline",
        },
        department: 'sales',
