First of all, I am sorry for my english. I speak french on a daily basis. I got a programming question related to CPA.. I didn't know in which of the two section I should post it. I think CPA section is the good one, if I am mistaking, you can move my thread to the programming section there is no problems.. I am making my own content locker. I really got no problems when it come to Geo targeting or a rotation of offer from differents network. My question is : how do you know when a visitor complete your offer? The content locker I seen here (not the Content Locker Pro.. I mean the homemade locker) disappear after a number of second that the programmer specifie.. That's not really a locker! I know I could buy CLP, I have no problems with putting the money to buy it BUT I still want to know because CLP and other locker don't do what I really want to do: I want my website members to get "credits" when the complete an offer.. I need to know when they complete it to give the credit.. Is it possible? To get a kind of "dispatch event"(don't know if it is the right expression but the actionscript programmer will understand me haha) when a user complete your offer? Thank you!
