I am trying to understand how Promoted Accounts (associated to an advertiser account) are related to line item. It looks like it should be many-to-one relationship between promoted account and line item but I am not able to confirm this.
My advertiser account has 2 promoted accounts associated with it. I created a Followers campaign through the Ads API and I see that it created a campaign with Product Type – PROMOTED_ACCOUNT on the backend. But I don’t see any association between promoted account ids and line item ids.
My question is how do I figure out if I can assign multiple promoted accounts or a single promoted account to a line item when I create a followers campaign?
