Good afternoon, I was hoping that someone can help me out with this. I have been setting up some campaigns from clickbank, however I would require to pass a sid or userid within the link for tracking purposes. I understand that I can give it a campaign code or what not, but how do I keep track of which members have completed sales? Is there a way to pass on a SID or USERID via PHP within the link? Any help would be much appreciated. Thanks.
Clickbank's tracking system is through "Tracking IDs" (the TID parameter on the end of your hoplink: http://hoplink/?tid=ABC123). Why do you want to pass user IDs through? Are you talking about from an affiliate point of view, or from a vendor point of view?
