From their documentation it seems there are several ways of checking. If I read correctly by adding a data attribute (data-callback) with your javascript function name in, it will be called once they have been verified.

So you could use a function that then redirects them like:

function redirect(){
   window.location = "http://domain.com/welcome";
}
