When a customer clicks on an affiliate link/banner and lands on your site integrated with the click tracking code (or lands on a replicated site), the click tracking code sends a request to the server which replies with a PAPVisitorId (a unique 32-character-long alpha-numeric string).
This PAPVisitorId is saved in cookies and gets saved in the database of Post Affiliate Pro or Post Affiliate Network if the click was associated with an affiliate.
The PAPVisitorId stores the following data inside a Post Affiliate Pro (Post Affiliate Network) database:
- merchant account ID (in Post Affiliate Pro it is always 'default1')
- IP address of the customer
- details of the affiliate whose link/banner was clicked
- banner ID, campaign ID
- date of visit
- time validity of the particular PAPVisitorId - a cookie limit that can be set inside campaigns of Post Affiliate Pro (Post Affiliate Network)
Even if a Standard Link (redirect) or Mod_Rewrite link is used there is a PAPVisitorId created on the domain where Post Affiliate Pro (Post Affiliate Network) installation resides.
