We use the subscription api to check the subscription status of contacts and also update the subscription status of emails. Recently, HS stopped allowing api key authentication and only allow oAuth. We updated all our endpoint to use oauth, but the subscriptions endpoints keep giving the error of missing scope and require the scope of content. This scope is not available to the regular HS user evidently and requires enterprise, professional or marketing based on the scope documentation. By requiring oAuth, they have basically took away previous functionality. I am stuck and not sure how to make this work. Please advise.
