Hopefully this is the right section, it is related to cpa but the coding i am asking about is PHP. So I have cpa lead on my site the code to make sure a the correct user is credited the correct amount is like: http://www.cpalead.com/mygateway.php?pub=*****&subid=$user I have pointclick track too: http://partners.pointclicktrack.com/gateway/content/pid/****/gid/****/ So I want to pass the username to the pointclicktrack so it can send a postback with the username which i can then give the correct user points. Would be correct: http://partners.pointclicktrack.com/gateway/content/pid/****/gid/****/sid2/$user Anybody had any experience with this? At the moment pointclicktrack sid2 is users IP and it is posting back the IP and i have to compare the IP to table, which is fine but would be better with username posting. Thank you in advance.
