Or also called as network builder. And we introduced this feature in DAP v4.4.
We call it DAP “Upline” – basically a shortcode called [DAPUpline] that allows you (site admin) to display the person’s upline’s affiliate code to the person. So in effect, it is a downline builder.
1) John joins your site
2) John fills out profile with (say) his ClickBank nickname
3) John refers Adam
4) When Adam logs in, he sees affiliate link to some xyz third party product, but CB nick in the affiliate link is replaced with John’s CB nickname.
5) Adam fills out his profile with his own CB nickname
6) Adam refers Jill
7) When Jill logs in, she sees affiliate link to same third party product, but cbnickname is replaced with Adam’s CB nickname.
This can be done with any number of third-party programs, as long as the nickname can be easily replaced with the info provided by the upline affiliate.
DAP even takes this one step further.
When Jill joins through Adam’s DAP affiliate link, if Adam has not filled out his CB nickname in his profile, then the third-party CB link shows CB Nickname of Site Admin in its place.
So if an affiliate fails to claim his affiliate link, then site admin gets credit for it (and all such links).
Here’s the documentation for [DAPUpline]
