This will open the live chat screen or the pre-chat form, depending on your settings.
chipBotApi.openLiveChat();
To pre-populate form data, use an object with the following properties for the first argument:
chipBotApi.hideVideoIcon({email: '', name: ''});
It is the same as the JavaScript function but uses HTML instead.
<a class="chipbot-open-chat">Open Live Chat</a>
Whenever you want ChipBot to open from a link, append ?start-chat
in the URL and it will automatically open ChipBot’s live chat functionality.
