Hello! I make use of the new iOS 15.4 SKAdNetwork.updatePostbackConversionValue feature: SKAdNetwork.updatePostbackConversionValue(0) { error in                 if let error = error {                     print(error.localizedDescription)                 }             } I am not sure why, but I always see this error message in the console: SKAdNetwork: Error while updating conversion value: Error Domain=SKANErrorDomain Code=10 "(null)" The operation couldn’t be completed. (SKANErrorDomain error 10.) Any idea what’s going on there? What does Error Code 10 mean? Couldn't find anything in the documentation about that so far. I have the NSAdvertisingAttributionReportEndpoint key with domain (https://api2.branch.io/v1/skadnetwork/advertiser_app) in my .plist.

On iOS 26 beta 3, after a user purchases an item, initiating a second order for the same product fails to process payment. The system returns the same transaction ID and displays an interface message stating: "You've already purchased this In-App Purchase. It will be restored for free."​​ ​​I’ve tested this – not only did the legacy StoreKit finishTransaction method fail to work, but StoreKit2 finish method also malfunctioned.​​ ​​When will Apple fix this issue? If unresolved, it will prevent a large number of users from making purchases normally, leading to disastrous consequences.​

在iOS26.4中，新的交易完成后[NSBundle mainBundle] appStoreReceiptURL 获取的是历史票据，未给出新的票据

Hi there 👋🏻 We are facing an issue that started on 24 June 2025 where some users that have an active subscription with an offer are not being able to use/restore their subscription since Transaction.currentEntitlements is empty. We have tried to call the server with this endpoint https://developer.apple.com/documentation/appstoreserverapi/get-transaction-history and it's returning the correct transactions correctly. Any idea what is happening?

Dear Apple Support Team, Hello! I am currently developing the in-app subscription functionality using Apple IAP API and have encountered a serious technical issue while processing subscription data. I would like to report this issue to you. Issue Description: When calling the subscription API endpoint, the same OriginalTransactionId returns inconsistent results. Specifically, a particular transaction ID (let's call it TransactionId_A) should belong to the subscription order with OriginalTransactionId_A, but it is currently incorrectly associated with OriginalTransactionId_B. This issue severely affects our ability to accurately manage and process subscription data. Here are the relevant log details for your reference: API Endpoint Requested: https://api.storekit.itunes.apple.com/inApps/v1/subscriptions/{TransactionId_A} (Note: The link is a placeholder for the actual API endpoint.) Log Information on February 21, 2025, at 09:40:09: { "AppAccountToken": "{AppAccountToken}", "BundleId": "{BundleId}", "Currency": "CNY", "Environment": "Production", "ExpiresDate": {ExpiresDate}, "InAppOwnershipType": "PURCHASED", "IsUpgraded": false, "OfferDiscountType": "", "OfferIdentifier": "", "OfferType": 0, "OriginalPurchaseDate": {OriginalPurchaseDate}, "OriginalTransactionId": "{OriginalTransactionId_A}", "Price": {Price}, "ProductId": "{ProductId}", "PurchaseDate": {PurchaseDate}, "Quantity": 1, "RevocationDate": 0, "RevocationReason": 0, "SignedDate": {SignedDate}, "Storefront": "CHN", "StorefrontId": {StorefrontId}, "SubscriptionGroupIdentifier": "{SubscriptionGroupIdentifier}", "TransactionId": "{TransactionId_A}", "TransactionReason": "PURCHASE", "Type": "Auto-Renewable Subscription", "WebOrderLineItemId": "{WebOrderLineItemId}" } Log Information on March 21, 2025, at 09:38:49: { "AppAccountToken": "{AppAccountToken}", "BundleId": "{BundleId}", "Currency": "CNY", "Environment": "Production", "ExpiresDate": {ExpiresDate}, "InAppOwnershipType": "PURCHASED", "IsUpgraded": false, "OfferDiscountType": "", "OfferIdentifier": "", "OfferType": 0, "OriginalPurchaseDate": {OriginalPurchaseDate}, "OriginalTransactionId": "{OriginalTransactionId_B}", "Price": {Price}, "ProductId": "{ProductId}", "PurchaseDate": {PurchaseDate}, "Quantity": 1, "RevocationDate": 0, "RevocationReason": 0, "SignedDate": {SignedDate}, "Storefront": "CHN", "StorefrontId": {StorefrontId}, "SubscriptionGroupIdentifier": "{SubscriptionGroupIdentifier}", "TransactionId": "{TransactionId_A}", "TransactionReason": "PURCHASE", "Type": "Auto-Renewable Subscription", "WebOrderLineItemId": "{WebOrderLineItemId}" } From the above logs, it is evident that the same transaction (TransactionId_A) returns different OriginalTransactionId values at different times, which is clearly not expected and severely impacts our ability to correctly process and manage subscription data. I hope you can address and investigate this issue as soon as possible. If you need any further information or assistance, please feel free to contact me. Thank you for your support! Best regards!

Our game application is developed based on StoreKit 1, and an exception occurs on iOS 26.4: after players complete a payment, the finishTransaction method fails to properly remove the transaction from the SKPaymentQueue; as a result, when players restart the app, the system still triggers the retry process for this transaction (reconciliation of unpaid orders). Has anyone encountered this issue? If there is a solution, we would appreciate it if you could share it with us.

Hello, I hope to find out more about how AppTransaction works on macOS, specifically about its internet connection requirements: if I use this to validate that the app is a legit purchase from the Mac App Store, I would not want it to have an always-on requirement just to validate. Does AppTransaction require the user to always be online for AppTransaction.shared ? When an app is downloaded from the Mac App Store, is the data needed for AppTransaction automatically embedded during that download, or is that data downloaded upon first launch of the app, therefore requiring an internet connection at launch time? Once the data/receipt has been downloaded by AppTransaction, is it cached until the app's next update, or is it cleared at some time during the version's life and needs to be re-downloaded, therefore requiring an internet connection at launch? Where is that receipt/data stored? Also, if you don't mind me sneaking in this non-related but sort of related question, in terms of receipt validation: Does macOS Sequoia's MAC address rotation feature affect receipt validation in any way when using IOKit? Thank you kindly, – Matthias

Hello, Since updating to iOS 26 Beta 3, I’ve been experiencing an issue where transactions purchased through the normal in-app purchase flow continue to be reported as updated and unfinished—even after calling the finish() function. Please resolve this promptly.

I has sandbox account with Japanese local. When i build app directly to check, price is displayed in Japanese Currency. But when I install app from the Test Flight, price is always displayed in USD Currency. the issue is appear in iOS 18.5 How can i fix this issue ?

Hey We have noticed a change in the retry behavior of Apple Server Notifications webhooks V2 starting around March 12–13, 2026. Previously, when our webhook endpoint returned an HTTP 400 response, Apple would retry the notification delivery multiple times according to the documented retry policy. However, beginning around March 12–13, it appears that Apple no longer retries the webhook when a 400 response is returned. The notification is sent only once and no further retry attempts are made. From our understanding of the documentation, retries should occur when delivery fails, and historically we observed retries even for some 4xx responses. We would like to confirm: Has Apple recently changed the retry behavior for Server Notifications? Are HTTP 4xx responses (specifically 400) now considered terminal failures that will not trigger retries? Is this change intentional or related to a rollout in the webhook delivery system? We have called the "Notification History" endpoint for some users who purchased a sub and we are only getting one attempt with the following data in it: { attemptDate: 1773469202552, (2026-03-14T06:20:02.552Z) sendAttemptResult: 'UNSUCCESSFUL_HTTP_RESPONSE_CODE', } This was 2 days ago, based on the docs, the user should have a few attempts at least. This behavior change affects systems that rely on retries to handle temporary validation issues or transient failures. Thanks!

We feel like we're at the end of the long and treacherous process of migrating to StoreKit2. But we've hit a small snag. When testing in the sandbox environment, we've found that if we don't finish a transactions, no subsequent purchase (invoked via call to purchase or the other purchase) will produce the confirmation sheet. Is this the expected behavior? The behavior is observed on iOS26 and 18. Our app will only attempt to finish the transaction if it successfully uploads the receipt to our API. If it fails to do so for whatever reason, the transaction is left unfinished. Whilst the user is informed about this, users will commonly try again. Our concern is that since the confirmation sheet will not be shown again, users will not know they are actually paying again - most certainly not the UX we want to have. We'd much rather have our users be fully aware when they're paying us money. The reason we're choosing not to finish the transaction until our backend has received it and confirmed the receipt to be valid is that the only way the user can get their product is if the server side is aware of this and add more time to the users account. When finishing the transaction via finish immediately after the purchase() call, the confirmation sheet is shown every time after subsequent calls to purchase(). Again, is this the expected behavior both in the sandbox and the production environments? Are we doing something wrong or misusing the product API? We are somewhat stumped because technically, we could get the first confirmation for a product purchase, and then finish it only after an arbitrary amount of calls to purchase() have been made - the user will believe they will have paid only once, but we will receive however much money we can drain from their account - most certainly not the kind of app we want to develop. Please advise and best regards, Emīls

Hello developers, We're facing a critical issue with our app and need your insights: Since today, 3 specific IAP products return empty data when calling Product.products(for: [productId]). This affects all users, preventing any successful purchases of these items. Other IAP products seem unaffected. let products = try await Product.products(for: [productId]) Key details: Production environment Issue started: 2025.6.17 No recent app updates All products show as "Approved" in App Store Connect Questions: Has anyone experienced similar issues recently? Could this be a StoreKit or App Store system problem? Any suggestions for diagnosing or resolving this, besides contacting Apple Support? Recommendations for temporary workarounds? This is severely impacting our business. Any help is greatly appreciated! Thank you!

Hello, I use Storekit2 to test the purchase of subscription products. After purchasing a subscription product in the sandbox, it will automatically renew 12 times, and then it will no longer automatically renew. When I click to purchase again, calling the try await product.purchase() method does not pop up the purchase pop-up window. In fact, it will directly go to the case let .success(.verified(transaction)): step, and the Transaction.currentEntitlements is empty

Hello DTS team, the request review from StoreKit is not working in iOS 26.4 beta 3. I have filed a feedback (FB22157147). Sample code: import SwiftUI import StoreKit struct ContentView: View { @Environment(\.requestReview) private var requestReview @State private var count = 0 var body: some View { VStack { Button("Increase Count") { count += 1 } Text(count, format: .number) .font(.largeTitle) } .onChange(of: count) { if count == 3 { Task { try await Task.sleep(for: .seconds(2)) requestReview() print("Request Review triggered!") // On iPadOS 26.4 beta 2 & 3, requestReview() does not trigger any review system sheet when testing in Xcode 26.3 // Works on iOS 26.3.1 } } } } }

Hey! We're implementing In-App Purchase Subscriptions and we were able to receive "App Store Server Notifications" on our "Sandbox Server URL". But the last event we received 22 hours ago. We are able to verify transactions and finish them, but receive no webhooks. We changed nothing on our server or its configurations but the notifications stoped to come. We consulted the API (https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/history) and it says the same as we see - the last event was 22hrs ago. I checked all the advices from here as well (https://developer.apple.com/forums/thread/805806?answerId=864483022#864483022). Is there any Status page for the Store Kit Sandbox services? Was there any outage? Sincerely, Konstantin

I’m testing an auto-renewable subscription on TestFlight. Now the user can't re-purchase the same product – Apple just restores the old (expired) one, and no payment sheet appears. How can I let the same TestFlight user re-subscribe to an expired product? Do I have to create a new productId for every test cycle?

Some paid users are unable to use the paid features unlocked by purchasing our subscription plan. It seems that this is due to StoreKit 2's Transaction.currentEntitlements not working the way we would expect it to work. Are you also encountering this issue? Do you have any idea to improve this situation? At launch, our app checks if the user is subscribed to the plan, using Transaction.currentEntitlements. As a result, the currentEntitlements array was empty. Our app then fetches the products from StoreKit 2 using Product.products(for:). As a result, the Product.SubscriptionInfo.RenewalState value of the corresponding Product (product.subscription.status.first.state) is subscribed, which confirms that the user has indeed purchased our plan, but seems to contradict the absence of the corresponding transaction in Transaction.currentEntitlements. Proactive in-app purchase restore and a restore purchase button calling the AppStore.sync() method are implemented, but using the button did not solve the issue.

We have some users who have upgraded to iOS 26 beta3. Currently, we observe that when these users make in-app purchases, our code calls [[SKPaymentQueue defaultQueue] finishTransaction:transaction]; method, and we clearly receive the successful removal callback in the delegate method - (void)paymentQueue:(SKPaymentQueue *)queue removedTransactions:(NSArray<SKPaymentTransaction *> *)transactions. However, when users click on products with the same productId again, the method - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions still returns information about previously removed transactions, preventing users from making further in-app purchases.

I'm encountering an issue with the App Store Server API where the appAccountToken is not preserved when users migrate their Apple ID email addresses. I've submitted Feedback Assistant ticket FB18709241 but wanted to check if anyone else has experienced this and get community input on best practices. The Issue When a user migrates their Apple ID from one email to another (e.g., from olduser@example.com to newuser@icloud.com), the App Store creates a new subscription transaction with a different originalTransactionId, but the appAccountToken is not carried forward from the original transaction. What I'm Seeing note: these values are fake When querying /inApps/v1/subscriptions/{originalTransactionId} with the either post-migration transaction ID or the pre-migration transaction ID, the API returns both transactions: Pre-migration transaction (status: 2 - inactive): originalTransactionId: "12345678910111" Contains: "appAccountToken": "abc123-def456-ghi789" Post-migration transaction (status: 1 - active): originalTransactionId: "67891011121314" Missing: appAccountToken entirely The Problem The appAccountToken is our only way to link App Store subscriptions to user accounts. Without it on the new transaction: Users lose access to premium features despite having valid subscriptions Server-side renewal notifications can't be matched to user accounts Manual support intervention is required for each affected user Questions for the Community Has anyone else encountered this issue with Apple ID migrations? What's the recommended approach for handling this scenario? Is there an alternative mechanism to maintain the subscription-to-user linkage across migrations? Questions for Apple Engineers Is this the expected behavior, or should the appAccountToken be preserved? Are there any planned improvements to handle this migration scenario? What's the best practice for developers to handle this case? Interestingly, both the old and new transaction IDs return the same JSON response from the App Store Server API, suggesting Apple maintains internal linkage between these transactions, but the appAccountToken isn't carried forward to the active transaction. Any insights or similar experiences would be greatly appreciated! Thank you!! Feedback Assistant: FB18709241

We have had a small number of users of our mac app complaining that the app suddenly can't detect their subscription or previous purchase history. These users are not new, and have been using the app successfully for some time. In the app we do this using the following (very standard) code at app startup: let result: VerificationResult<AppTransaction> = try await AppTransaction.shared For those users experiencing the failure, the result is coming back as unverified. So far we've been unable to find the cause or a solution, but it seems to have become worse with the release of macOS 15.4. We've tried resetting, rebooting and reinstalling the app. It's worth adding the (probably obvious) that it's impossible to test or fault-find with this, because we can't replicate the issue in a development environment. Any suggestions gratefully received.
