Is it possible to generate a new receipt for the same transaction on device?
Hi, all! I am wondering about something about App Receipts. I'm using App Receipt hash to key some information server-side. I'm curious however, if that doesn't actually have a possible flaw. Is it possible to get a new receipt that would yield a different hash for the same transaction? Reinstalling the app, perhaps? Installing the app on a new phone? Basically, I want to make sure this hash is something I can rely on. If the user can get a new hash for the same purchase, that's obviously problematic. Thanks!

不正利用された場合、Apple ID不正利用時とクレジットカード不正利用時で、アプリ側が行う標準的な対応プロセスは変わるのか
アプリに課金を実装しようと思うのですが、もし不正利用された場合、アプリ側は基本的にApp Storeを通じて対応するよう案内するのが一般的と思いますが、Apple ID不正利用時とクレジットカード不正利用時で、アプリ側が行う標準的な対応プロセスは変わるのか教えていただきたいです。 また下記内容は標準的な対応プロセスとして問題ないでしょうか?
 ■Apple ID不正利用時 → ユーザー自身がAppleサポートに連絡し、パスワード変更・二段階認証の設定・不正購入の返金申請などを行うよう案内する。 ■クレジットカード不正利用時 → まずカード会社への連絡を促すが、アプリ内決済に関してはAppleのカスタマーサポート経由で返金や調査手続きを案内する 不正利用されたユーザーへの対応に備えて、アプリ側が考慮すべきことがあれば教えてください。

Inquiries about API SERVER Notification
Inquire the types of notifications that can occur in a SANDBOX environment Hello, WWDC 2024 is trying to conduct a test to receive notifications related to ONE_TIME_CHARGE, CONNSUMPTION_REQUEST, CONMSUMPTION_INFO, REFUND, and REFUND_DECLINED as described in the example of purchasing consumables, but as a result of the continuous search, I found that it is difficult to occur except for ONE_TIME_CHARGE. So, in order to verify only the business logic as shown below, we are testing only the business logic without actually calling the API after purchasing the test and saving the signaled Payload that we received in response to ONE_TIME_CHARGE. Can we actually request a refund for the test purchase and receive the corresponding notification and actually send the response? public void handleSignedNotification(String signedNotification) throws Exception { ResponseBodyV2DecodedPayload payload = signedDataVerifier.verifyAndDecodeNotification(signedNotification); NotificationTypeV2 type = payload.getNotificationType(); //For Apple Server Notification, only ONE_TIME_CHARGE notifications are enabled in the test environment, so for testing, change them as below to test whether they are running business logic type = NotificationTypeV2.REFUND; log.info("Apple NotificationType : {}", type); switch (type) { case CONSUMPTION_REQUEST: handleConsumptionRequest(payload); break; case REFUND: handleRefund(payload); break; case REFUND_DECLINED: handleRefundDeclined(payload); break; // For other necessary notifications, just take a log default: log.info("Unhandled notification: {}", type); } } Regarding the call of 'CONSUMPTION_INFO', which is the response of 'CONSUMPTION_REQUEST' Is there a value that WWDC 2024 must include when sending CONMSUMPTION_INFO, which is the response to CONNSUMPTION_REQUEST described in the refund example? I'm going to call the API with only sample provision and consumption like the sample code you introduced in the video. I was told to submit my refund preference within 12 hours, but can I submit it as UNDECLARED at first and use the method to express my intention? When I receive the notification, I will save it in the DB and save it in the administrator page of the service so that the administrator can choose. 2-1. Some of the materials I looked for are told that Apple can proceed with the refund even 12 hours ago, and to express your opinion as soon as I receive the notification, but I wonder if this is correct. If you get a notification as below, you should write whether you used it or not by referring to the consumption information. I think the customer said to check whether the data was provided when applying for a refund. Should I take it out of decodedTransaction, check the value, and just call it NO_PREFERENCE? I'd appreciate it if you could give me some advice. Below is a part of the code I implemented. private void handleConsumptionRequest(ResponseBodyV2DecodedPayload notification) throws Exception { // 1. transaction ID get String signedTransactionInfo = notification.getData().getSignedTransactionInfo(); JWSTransactionDecodedPayload decodedTransaction = signedDataVerifier.verifyAndDecodeTransaction(signedTransactionInfo); String transactionId = decodedTransaction.getTransactionId(); // 2. Extract the relevant transaction (The following example is an in-app payment and will be accumulated in two types of DBs, stored in one of the two) Sample sample = sampleService.findByAppleTransactionId(transactionId); Example example = exampleService.findByAppleTransactionId(transactionId); Boolean canRefund = false; // 3. Check consumption information if (sample != null) { canRefund = checkSampleStatusForApplePurchaseRefund(sample); } else if (example != null) { canRefund = checkExampleStatusForApplePurchaseRefund(example); } // 4. Create Refund Preferences RefundPreference refundPreference = determineRefundPreference(canRefund); // 5. Creating a ConsumptionRequest Object ConsumptionRequest request = new ConsumptionRequest() .refundPreference(refundPreference) .sampleContentProvided(true); log.info("forTest~ canRefund: {}", canRefund); log.info("forTest~ sample: {}", sample.toString()); log.info("forTest~ example: {}", example.toString()); log.info("forTest~ refundPreference: {}", refundPreference); log.info("forTest~ request: {}", request); // 6. Transfer to App Store (annotated with dummy requests that only confirm current business requests are going right) // appStoreServerAPIClient.sendConsumptionData(transactionId, request); }

In-app purchase fails at first attempt, succeeds at second
Our macOS app has one in-app purchase (IAP) implemented using StoreKit 1. It works for us and beta testers but App Review get SKErrorDomain Error Code 0 / ASDErrorDomain Code 500 / AMSErrorDomain 305 on first attempt to make the in-app purchase. However, the purchase succeeds at second attempt. We've looked through our entire IAP related code and App Store Connect setup but can’t find the reason. It's a standard implementation: LegacyPaymentQueueObserver for SKPaymentQueue observation. AppDelegate for initiation of payment queue observation on app launch LegacyStoreKitPurchasableProduct for initiating a purchase and listening for the result LegacyStoreKitProductsRequester for how we load the product before user can make in-app purchase. It happens this way: PreviewResultsViewModelcalls loadProducts()on an instance of StoreKitPurchaseManager, which asks an instance of LegacyStoreKitProductsRequesterto requestProducts(forIdentifiers:) Any guidance to resolve this would be appreciated.

Verify Receipt is not found - After successful payment for Annual subscription.
The application is developed with Xamarin Framework and it is live now. The customer installed the app and purchased the annual subscription. And for some reason, they uninstall and reinstall the application on the same device. Now user wants to restore the subscription. In the application, there is an option to Restore the subscription. But restore API not return purchase details. But when clicking the subscription button instead of restoring the subscription, it says you subscribed to this plan". is there any possibility of not getting VerifyRecipt even after a successful purchase?

Revoked Non-Consumable Purchases & currentEntitlements
We use Transaction.currentEntitlements in StokeKit 2 to unlock functionality based on a Non-Consumable IAP but we have a case involving a refund that seems wrong and I am trying to understand the interation between transactionId, originalTransactionId & revocationReason. The Context: We have a universal App on macOS and iOS that offers a shared Non-Consumable IAP. For this example I have named it "app.lifetime" On macOS we use StoreKit 2 and I am calling the Transaction.currentEntitlements and Transaction.all functions. On iOS we are still using StoreKit 1. This example customer: Originally purchased "app.lifetime" on 2024-10-27 Was refunded by Apple for "app.lifetime" on 2024-10-29 Re-purchased "app.lifetime on 2025-02-24 (I have seen an email receipt of this transaction but it never shows up in Transaction data) (all the above happened on the mac via StoreKit 2) The Transactions (all lightly redacted for privacy): on macOS the following is returned from Transaction.currentEntitlements... { "appTransactionId" : "...8123", "bundleId" : "app", "currency" : "USD", "deviceVerification" : "...", "deviceVerificationNonce" : "...", "environment" : "Production", "inAppOwnershipType" : "PURCHASED", "originalPurchaseDate" : 1729997808000, "originalTransactionId" : "...9955", "price" : 1, "productId" : "app.lifetime", "purchaseDate" : 1729997808000, "quantity" : 1, "signedDate" : 1740416289102, "storefront" : "USA", "storefrontId" : "143441", "transactionId" : "...7511", "transactionReason" : "PURCHASE", "type" : "Non-Consumable" } Note in the above example the originalTransactionId & transactionId are different. Transaction.all however returns both transactions: [ { "appTransactionId" : "...8123", "bundleId" : "app", "currency" : "USD", "deviceVerification" : "...", "deviceVerificationNonce" : "...", "environment" : "Production", "inAppOwnershipType" : "PURCHASED", "originalPurchaseDate" : 1729997808000, "originalTransactionId" : "...9955", "price" : 1, "productId" : "app.lifetime", "purchaseDate" : 1729997808000, "quantity" : 1, "revocationDate" : 1730224102000, "revocationReason" : 0, "signedDate" : 1740415969925, "storefront" : "USA", "storefrontId" : "143441", "transactionId" : "...9955", "transactionReason" : "PURCHASE", "type" : "Non-Consumable" }, { "appTransactionId" : "...8123", "bundleId" : "app", "currency" : "USD", "deviceVerification" : "...", "deviceVerificationNonce" : "...", "environment" : "Production", "inAppOwnershipType" : "PURCHASED", "originalPurchaseDate" : 1729997808000, "originalTransactionId" : "...9955", "price" : 1, "productId" : "app.lifetime", "purchaseDate" : 1729997808000, "quantity" : 1, "signedDate" : 1740416289102, "storefront" : "USA", "storefrontId" : "143441", "transactionId" : "...7511", "transactionReason" : "PURCHASE", "type" : "Non-Consumable" } ] Note here that the original transaction ("...9955") includes a revocationDate and revocationReason that match the expected refund but the secondary transaction that seems to match on all other details is missing the revocation info. Looking at the iOS SK1 receipt data to compare, after a receipt refresh I see only a single transaction "...9955" which includes the cancellation info and transaction "...7511" is not present at all. The impact of this is that on iOS we are considering the purchase void but on macOS we are following currentEntitlements and consdering it still valid. Calling the inApps/v1/history/... server API with the "...7511" transactionId that is shown in the currentEntitlements response returns the "...9955" transaction with the correct revocation status but "...7511" is no returned at all. To Summarise: currentEntitlements on macOS shows transaction "...7511" as active and with an originalTransactionId of "...9955" all on macOS includes both "...7511" as active and "...9955" as revoked iOS reciept data shows only "...9955" as revoked Server API shows only "...9955" as revoked event when explicitly called with "...7511" Neither of them show a more recent purchase the same customer made for the same IAP product. My questions are: Is this a StoreKit bug or am I mis-understanding something? If it's a bug how can I work around it to ensure revoked purchases aren't still appearing in currentEntitlements? Under what conditions can StoreKit generate multiple transactionIds for the same underlying originalTransactionId? I had assumed (and the docs suggest) this only happens for subscriptions but here it is happening for a Non-Consumable IAP. Why would transactionId "...7511" only be present on macOS/SK2 and not visible at all on iOS/SK1 or API? I don't understand why the latest IAP from 2025-02-24 that the customer assures me they made (and has shown me the receipt for is not showing up in the Transactions history at all. Any ideas?

not getting stable release versions of some apps from the ios app store
I have been receiving beta software from the iPad App Store, despite not being enrolled in a beta program. Additionally, I do not have TestFlight or the Feedback app installed on my device. There are no certificates or profiles displayed either. I am using the App Store app that comes preinstalled on my device (note that I am not located in Europe). My iPad has been experiencing significant bugs, including numerous screen glitches and periods of sluggishness. Furthermore, numerous applications have crashed frequently. I was able to confirm that I was receiving beta software because the crash reports include beta identifier numbers. According to Apple documentation regarding analytic reports, a beta identifier will only be visible for beta applications. anyone know what could be going on or how to fix this?

Transaction.id will be repeated in Apple in-app purchase
In the sandbox environment, when I quickly and repeatedly purchase an item, Transaction.id will be repeated. Will there be duplication in the production environment? func pay(productId: String, orderId: String) async { guard !productId.isEmpty, !orderId.isEmpty else { return } let orderObj = ApplePayOrderModel.init(orderId: orderId, productId: productId) do { let result = try await Product.products(for: [productId]) guard let product = result.first else { return } let purchaseResult = try await product.purchase() switch purchaseResult { case .success(let verification): switch verification { case .verified(let transaction): orderObj.transactionId = String(transaction.id) await transaction.finish() case .unverified(let transaction, let error): await transaction.finish() } case .userCancelled: break case .pending: break @unknown default: break } } catch { print("error \(error.localizedDescription)") } }

Using child accounts with sandbox IAP testing
Hello, thank you for your time. I'm using several physical devices to test IAPs in builds from xCode. Some of my test devices are logged into child accounts from my family account. Child accounts "Ask Permission" from devices logged into adult accounts in the family. when you attempt to make a purchase. I'm hoping to be able to use these devices to test my IAPs but I get the following error after supplying the password for the sandbox account: Unable to Ask Permission You can't ask permission because you have signed in with iCloud and iTunes accounts that are not associated with each other. [Environment: Sandbox] Is there any way to make this work?

Auto Renew Subscription Model
Hi, I want to offer an auto-renewable subscription (e.g., $1/month) that grants users (10 document analyses per month), with the count resetting at the start of each billing cycle. -Unused analyses will not roll over to the next month- Additionally, any analyses generated while the subscription is active will remain accessible to the user permanently, even if they cancel the subscription. The paywall, app description, and metadata will clearly state that the subscription grants (10 document analyses per month with no rollover) We want this to be implemented as an auto-renewable subscription model, not as a consumable service or a token/credit system (which we want to avoid). Is this model acceptable under Apple’s guidelines, or would it be considered a token/credit system? Any insights or alternative suggestions would be appreciated.. Thanks

Help: IAP Works in Xcode but Not in TestFlight – Cannot Link IAP to Version for Review
Hi everyone, I've been going back and forth with Apple’s review team for over 10 days now, and I'm still unable to get my first In-App Purchase (IAP) working correctly. Here's what’s happening: ✅ The IAP works perfectly when I build and run directly from Xcode. ❌ However, when I test the app via TestFlight, tapping the purchase buttons does nothing—the IAP sheet doesn't appear. Key issue (I think): I believe the IAP hasn't been submitted properly for review. On App Store Connect, I cannot select the IAP under the “In-App Purchases” section of the version submission page. It's grayed out or not listed at all. As a result, Apple keeps rejecting my binary due to the IAP not being included in the review. What I’ve already done: Created the IAP (non-consumable) Set pricing and cleared all errors Checked Bundle ID, Product ID, and entitlements Added In-App Purchase capability to the app target Uploaded the binary via Xcode Waited multiple times for status updates My questions: What’s the correct process to link the IAP to a specific app version if it doesn't show up in the version page? Could this be an issue with App Store Connect metadata or approval timing, or am I missing something in Xcode/build settings? Is there any way to force re-sync the IAP so it appears when submitting the build? Has anyone resolved a similar issue recently? This process has been incredibly frustrating, and the feedback from the review team so far has been very vague. I would really appreciate any detailed insight or steps to ensure the IAP is submitted correctly and works on TestFlight. Thank you in advance!

Old developer account still receiving payments after migration
Hi, I've migrated my app to another developer account more than half a year ago, but I'm still receiving a few transaction payments in the old developer account, which currently has no app. The payment date shown in the report is last month. I'm wondering how could this happen. Is it possible for users to initiate a transaction half a year ago and only successfully pay it now?

tvOS In-App Purchase – App Not Returning After Redirecting to Settings for Apple ID Verification
I'm encountering an issue with In-App Purchases on Apple TV (tvOS): When a user initiates an IAP for the first time, the system prompts them to sign in with their Apple ID, and the purchase proceeds normally. However, on subsequent purchase attempts, if the Apple ID session has expired or additional verification is required, the system redirects the user to the Settings app to sign in again. After the user signs in via Settings, the app does not automatically return to the foreground. The user must manually press the Menu button to come back. Is this is the normal behaviour of apple tv for InApp purchase? or did I need any code improvement to solve this? What I'm trying to achieve: I'd like the app to automatically return to the foreground once the user has completed the Apple ID login in Settings. Is this behavior supported on tvOS? If not, is there any known workaround or best practice to guide the user back to the app smoothly? Any advice or guidance from Apple or other developers would be greatly appreciated!

In iOS 26 beta3 version, the finishTransaction method is unable to remove transactions from the SKPaymentQueue, causing transactions to remain in the queue even after being processed.
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.

Migrating to StoreKit 2
Hi Friends, I have an iOS app, which uses around 500 in app purchases for various modules. I am using StoreKit for in app purchase, now trying to migrate this to StoreKit 2. I am using Product.products(for:) method to fetch all the products by sending identifiers of all the 500 In app purchases. In response, I am getting details of only 160 products, the method is not returning remaining in app purchases. What could be the reason for this behaviour, how to get rid of the issue? May be is this the issue will happen only on TestFlight? If someone from Apple assures about it, we have plan to submit the app. Please advise, Thank you.
