I'm developing a payment system to be used in conjunction with social media apps like instagram. On these platforms influencers are allowed to keep accounts 'private' and only approve certain followers. My system will allow these influencers to charge a fee to be admitted as a follower to these private accounts. My system operates completely independent of these apps, but the net result of the system will be followers paying for content that the influencer (not the app) is approving on the platform. Does apple view this as an InApp payment requirement to the social media application?
