Info

Auto-Generated Documentation for the Flex Webchat UI is now available as a public beta distribution. The auto-generated documentation is accurate and comprehensive but may differ from what you see in the official Flex Webchat UI documentation.

You can change the Flex WebChat 2.0 look, feel, and behavior via configuration settings. You can override any of the default configuration values.

There are two ways to configure the Flex UI:

via componentProps in the Configuration Object
via the defaultProps API

Using the Basic Configuration

Basic configuration allows you to do customizations to WebChat display options and behavior. With a few lines of code you can make changes like:

Show or hide the logo in the header
Change the properties of any WebChat component
Pass context for routing or to be displayed to an agent
Configure how the author of the message is displayed
Show or hide a typing indicator or message read receipt

and much more.

Configuration object

In the configuration object, you can define default properties to WebChat Components (listed below) and also configure properties that are not tied to specific Components.

WebChat default configuration

1const defaultConfiguration: Config = {
2    disableLocalStorage: false,
3    available: true,
4    colorTheme: {
5        baseName: "BlueMediumTheme"
6    },
7    componentProps: {
8        MessagingCanvas: {
9            avatarCallback: (identity: string) => SessionActions.getAgentAvatar(identity),
10            showTrayOnInactive: true
11        },
12        MessageCanvasTray: {
13            onButtonClick: () => Actions.invokeAction("RestartEngagement")
14        }
15    },
16    tokenServerUrl: "https://iam.twilio.com/v1/Accounts/{accountSid}/Tokens",
17    flexWebChannelsUrl: "https://flex-api.twilio.com/v1/WebChannels",
18    context: {
19        friendlyName: "Anonymous"
20    },
21    startEngagementOnInit: true,
