I want to update/add a custom audience to already ACTIVE facebook ad campaign. Custom Audience is part of the Adset. I am not able to find the field in Adset which corresponds to custom audience. Also it's possible to do this in Ads manager, is it possible via graph api's that meta provides or java SDK?
I tired going through facebook documentation here (scroll down to Adset heading) couldn't find the field. Also i have all my campaigns/adsets/ads in draft mode so i can't play with graph apis(facebook doesn't return data in apis for status=draft)
