Or do you mean the time you accessed after the in-app purchase? lifetimeDollarsPurchased/lifetimeDollarsRefunded: If the app has multiple accounts for that customer, is the purchased/refunded amount for all accounts?

There are several auto-renewable subscriptions with the same 'webOrderLineItemId' value. (The 'originalTransactionId' value is the same and 'transactionId' is different.) If you look up the History API based on 'originalTransactionId', you can see that only one auto-renewable subscription with the same 'webOrderLineItemId' value is viewed. What is the criteria for looking up? I searched History API based on 'originalTransactionId' value. However, auto-renewable subscriptions that do not match 'originalTransactionId' are also being viewed in response. What is the reason? https://developer.apple.com/documentation/appstoreserverapi/get_transaction_history
