The following document states that some APIs in Storekit1 have been deprecated and that migration to Storekit2 is recommended, but I understand that Storekit2 only supports Swift. I'm currently creating an iPhone app in Objective-C, but is there a way to implement APIs equivalent to Storekit2 using a different Objective-C API? https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-18-release-notes#StoreKit

We are currently performing maintenance and operation on our app. I would like to ask a question about Apple's purchase processing. When retrieving purchase information for a user who has multiple original transaction IDs, such as original transaction ID AAA and original transaction ID BBB, if "Get All Subscription Statues" is executed with BBB as an argument, is it possible that purchase information for original transaction ID "AAA" will be retrieved? If this kind of issue does occur, please share the conditions under which it occurs.

Regarding App Store Server Notifications V2,we are currently using Notifications V2 in a production environment. It is set up so that if the server receives the notification successfully, it returns 200 after about 30 seconds, and if an error occurs, it returns 400 or 500. However, the notification is being resent multiple times from Apple's server, at 1 hour, 12 hours, and 24 hours. Is it necessary to return the notification using Apple's API?

Please let me ask you about the following status code obtained from the AppStoreServerAPI. 3: The auto-renewable subscription is in a Billing retry period. 4: The auto-renewable subscription is in a Billing Grace Period. 5: The auto-renewable subscription is revoked. the App Store refunded the transaction or revoked it from Family Sharing. For these status codes 3 to 5, would this mean that the service has not been purchased? And will they change to a status of ‘2: The auto-renewable subscription is expired’ after a certain period of time without the payment issue being resolved?

When the user's purchase information was retrieved from Japan using the AppStoreServerAPI, I was able to obtain it with the status ‘1: The auto-renewable subscription is active.’, However, the expiry date in the Payload was the previous day. How can this be the case? Example: when the purchase information was retrieved on 10/02/2025 at 21:00:00, the expiry date for status ‘1’ was ‘2025/02/09’.

When using the AppStoreServerAPI to retrieve user purchase information or decode a Payload, The following responses occur multiple times throughout the day. If there is no error, the process is completed successfully. HTTP response code: 502 for URL What is the cause of this error occurring repeatedly? Is there still a problem with Apple's server status? The following APIs are used to acquire and decode user purchase information. 　AppStoreServerAPIClient.getAllSubscriptionStatuses 　SignedDataVerifier.verifyAndDecodeTransaction 　SignedDataVerifier.verifyAndDecodeRenewalInfo

We are considering a price change for the auto-renewing subscriptions we currently offer in a Production environment and have made system modifications to our servers. We would like to implement a price change for purchases made through our SANDBOX Apple account in order to test if our system is capable of handling the price change.

We distribute apps that offer auto-renewing subscriptions. In order to test a new service, we would like to create a new subscription group and subscription product (hereinafter referred to as “test subscription”) for this app. If the “In-app purchase statuses” of the test subscription is “Ready to Submit” is the following behavior correct? ・General end users cannot purchase the test subscription. ・Users with SANDBOX Apple accounts can purchase the test subscription.

When submitting an app for review, will any unreviewed auto-renewing subscriptions within the app be reviewed simultaneously? I own an app that has passed review and offers an auto-renewing subscription A within the app that has also passed review. To test a new service, I plan to create a new auto-renewing subscription B, which I do not intend to submit for review. After creating Subscription B, I plan to submit the app for review as part of an app update. In that case, is there a possibility that Subscription B will also be reviewed?

We are currently using App Store Server Notifications V2 in a production environment, but occasionally encounter the error "Failed to parse signedTransactionInfo in the notification payload. status=VERIFICATION_FAILURE." What could be the cause of this error? Also, is there a way to resolve this error? After the notification from Apple was received on the server side, it was passed to the Apple library and an error occurred in the Apple library when decryption was performed.
