The Dixa chat widget has a javascript API that allows you to control language, close/open view, change widget text and sign in a user.

You can test the API by opening the javascript console in Chrome dev tools, for example. The API uses the global script.

Example:
If you want to change the widget from minimized to conversation view after 60 seconds, add this code to your web page:
setTimeout(function () {_dixa("api.setView", "conversation")} , 60000)
