Tracking referral partners without using their links

I have a YouTube ad buyer as a referral partner. YouTube does not allow redirects for their ad URL’s therefore we cannot use the standard referral partner link (because they all redirect through IS). I have a form on an external website (clickfunnels) that I want to track my YouTube referral partner. Has anyone come up with a solution to track referral partners without using the partner link? Maybe a hidden field that tracks back a referral partner?

Hi Gary, do es that page ONLY exist for that referral partner, ie anyone who comes in via the mechanism is assigned to that specific person?

If yes then thats actually dooable.

If no I’m not sure you can do that
