I'm having trouble with "Subscriptions" on the Apple Store. Users can purchase multiple courses. Multiple courses can have the same price and use the same "Subscriptions". Suppose I have user A, course C1 costs 200 USD (PRODUCT_ID: 200_USD), course C2 costs 200 USD (PRODUCT_ID: 200_USD). When creating a registration, the json response from apple is all in the in_app section, has the same id_product_id, it is not possible to distinguish which element belongs to course C1, which element belongs to course C2. How do I know which renewal item belongs to course C1 or C2?
