I'm trying to use the appstore connect REST API to create an introductory offer for one of our subscriptions. The introductory offer should exist in all territories our app supports. I successfully created an intro offer for all territories, but only by calling POST https://api.appstoreconnect.apple.com/v1/subscriptionIntroductoryOffers (https://developer.apple.com/documentation/appstoreconnectapi/create_an_introductory_offer) 175 times, once for each territory. Is there a more efficient way to do that? The API documentation has no explanatory text, only the types and payloads. I used those to piece together the following approach. I am not sure if this is even the intended way to use the API, so please correct me if I'm wrong. Call GET https://api.appstoreconnect.apple.com/v1/subscriptions/{id}/pricePoints with territory filter USA to get all available price points in USD From the result list, pick the price point whose customer price is closest to the one I wish to set up Call GET https://api.appstoreconnect.apple.com/v1/subscriptionPricePoints/{id}/equalizations to get equivalent price points in all territories Call POST https://api.appstoreconnect.apple.com/v1/subscriptionIntroductoryOffers for each the USA's the and other territories' price points Now my question. The create intro offer endpoint takes as payload an object of type SubscriptionIntroductoryOfferCreateRequest (https://developer.apple.com/documentation/appstoreconnectapi/subscriptionintroductoryoffercreaterequest), which has a field "included", which is a list of price point IDs. In my step 3 above I have a list of price point IDs, and the field name and type suggests to put them here to create an intro offer for all territories in one API call. However, this does not work. The field "included" seems to have no effect whatsoever, no matter what I put in there. Is there a way to create an intro offer for all territories in one go, or do I have to call the create endpoint multiple times?
