Thanks Juan for the info! To elaborate, when you are editing your Facebook Lead Ad Form, go to Settings, and then Field IDs. Scroll down to where you see "Consent 1". Whatever you have as the label for Consent 1 will be the queryable value that you can add/map in Marketo. For example, my "Consent 1" field ID is "yes". In the Marketo / Lead Ad Integration field mapping, "yes" is what I mapped to a TempField in order to opt people in/out. You would think that "Consent 1" would be the queryable field in the Field Mapping, but no, it is the label (in my case, the word "yes"). Hope this helps!
