Problem is that I want to track the conversion back to an individual FB user. That way FB can start learning what users are converting so they drive more converting users to me. It would be great if I could dynamically append a unique FB user ID which I could then feed back to FBs offline conversion tracking.

you should be able to add some parameters like `ref=fb` to the url

I am advertising affiliate links directly through Facebook ads which means I cannot use a Facebook pixel to track conversions as the user goes straight to the affiliate website.

The affiliate link allows me to pass a unique ID which will be displayed if a conversion takes place. Is it possible to append a unique ID to a Facebook ad URL so I can add offline conversion data to Facebook with the unique ID of the converted user?

Just curious how other people deal with tracking affiliate conversions on Facebook.
