For some advertisers, on ads.twitter.com I see additional drop-down showing “On all channels”, “On Twitter”, “On Twitter Audience Platform”.
I assume “On Twitter” corresponds to ALL_ON_TWITTER placement from analytics, and “On Twitter Audience Platform” to PUBLISHER_NETWORK.
Since in analytics I cannot query both ALL_ON_TWITTER, PUBLISHER_NETWORK, I need to make 2 separate calls, but how to determine if PUBLISHER_NETWORK data is available at all?
