I want Facebook's tracking pixel to add to prosper 202 traffic source, i've read the facebook help guide where it says to click the conversion tracking tab from power editor, but it's not there.
If it isn't available anymore what do I use as an alternative, or would just have to leave that part out in Prosper 202?
That conversion pixel has been gone for a long time, but it looks like they are bringing it back. Chances are they have changed the help files around it but it's not yet available to you. Better to ignore it and add subids to track ad-level conversion data in Prosper202, since you'll need that to look at EPCs/ROI/dayparting etc anyway. Might as well ignore the FB conversion pixel for now.
