Hello! In our app we use Advanced Commerce API with generic consumable products. Does Apple validate SKU of payment request? So if user have several pending purchase requests with same SKU (inside item) will Apple charge only for the latest one or all of pending requests even though SKU is the same?

Hello! Is it possible to test in Sandbox the flow of pending purchase request changes to succeed for Advanced Commerce API? As StoreKit configuration file can not be used with Advanced Commerce API, how to test for example flow "Ask to Buy" when child account ask parent account to buy generic consumable product? And also does Advanced Commerce API supports feature "Ask to Buy"?

Hey! App is approved for Advanced Commerce API and have generic product id (Consumable) for digital items purchasing. Uncertain on ho to test flow of pending purchase changing it's status to failed. As by docs BE side handling creating jws for purchase (also creates order to keep track of which items user bought) app with signed jws initiate purchase via product.purchase (send data for advancedCommercialData in options). If product purchase returns status .pending (still no transaction created) I notify BE that for that item (using item SKU) user has pending status for purchase, so that when user attempts to buy this exact item we do not create order duplicate. So the first question - do we need to check if user already made an attempt to buy this item and if item purchasing is pending decline another attempt of buying it? If user sends several requests to buy item under similar SKU for advanced commerce api do all of them will be charged or only one (does apple check SKU value when making a purchase of consumable product via advanced commerce api)? Another question is how to test purchase returns pending status for consumable item via advanced commerce api and then for that item (by SKU) changes status from pending to success? How to know (and eventually) test that after purchase of item via advanced commerce api firstly returns .pending status and then changes to .failure? I want to prevent users from trying to create order duplicates for single item, so when product purchase returns pending status I sent to BE id of item and order for this item on BE side will be marked as pending. So if user tries to buy this exact item once more and status of order on BE still .pending no new purchase will be initiated. So I need to know when purchase changes it's status to failed and then delete pending order on BE side, so that user will have an ability to initiate purchase for this item once more. How to tell whether .pending status for item changes to failed, will I be able in case of failed gather SKU that I previously passed in advancedCommercialData)?
