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.

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)
