Updating Params
How to Update Params/Tokens on JS?
<script type="text/javascript"> kUrl='http://keitaro_url/'; function update_tokens(subId, param, value) { var img = document.createElement("img"); img.src= kUrl + '?_update_tokens=1&sub_id=' + subId + '&'+ param + '=' + value + '&return=img'; img.height=0; img.width=0; document.getElementsByTagName("body")[0].appendChild(img); } </script>
Now, you can call such function:
update_tokens('{subid}', 'sub_id_8', 'test')
In case, the landing page is already using Tracking Script, you can just call this method:
KTracking.update({sub_id_8: 'test'})
