Unbounce Cross Domain External Tracking

tracking_url.js

// On external pages (same domain) you need to grab the cookie
function getCookie(name) {
  var value = "; " + document.cookie;
  var parts = value.split("; " + name + "=");
  if (parts.length == 2) return parts.pop().split(";").shift();
}
var url = "http://t.unbounce.com/trk?v=" + getCookie('ubvt') + "&g=convert"

// On the unbounce page itself you have direct access 
var url = "http://t.unbounce.com/trk?v=" + ub.page.visitorId + "&g=convert"

/* 
  To track a conversion from anywhere you need to send a GET request to the url you generate above.
 
  If you do this server side you need to set a UserAgent
  $ curl -A "UserAgentString" "http://t.unbounce.com/trk?v=212.62.201.2481435531293450082&g=convert"
  
 In the browser you can issue the GET request like this:
  <script>  
    var script = document.createElement("script");
    script.src=url;
    script.type="text/javascript";
    script.async=true;
    document.body.appendChild(script);
  </script>
