We track the sales exactly the same way as other sales, using affiliate cookies. First cookie wins, cookie expires after 14 days and is non-rewritable, but renewable after 14 days. If Lifetime+ is ON in the Programs menu of your account and the user is new to our network of live sex cam sites, the account is bound to your account and you keep receiving commissions after their credit purchases, whether or not the user still had your cookie in their browser. If you promote your Whitelabel with the Video Promotion API then the general Whitelabel program will be applied for your sales.
