Hi Apple Support, I am encountering an issue while testing in-app purchases in the sandbox environment. I have created a sandbox tester account Logged out of the App Store and System Settings on my Mac. My main developer account is signed in under Sign In & Capabilities in Xcode. The Bundle ID matches the one configured in App Store Connect. The Product ID I am querying also matches the configuration. Deleting the app and reinstalling. Restarting my Mac. When running my code in debug mode, I observe the following: Running debug build App Store environment: Production [1b294b55] Error updating Storefront: Error Domain=StoreKit_Shared.StoreKitInternalError Code=7 "(null)" Valid products: [] Invalid product IDs: ["com.x.x.x.monthly"] No products found The Product ID (com.x.x.x.monthly) matches the one I have configured in App Store Connect. The bundle id matches. When I create a StoreKit Configuration file in Xcode and sync it with my app, I can see the product IDs correctly. Below are the relevant code snippets for fetching and handling products: func fetchProducts() { guard !productIDs.isEmpty else { print("No product IDs configured") return } let request = SKProductsRequest(productIdentifiers: productIDs) request.delegate = self print("Starting product request...") request.start() } func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) { DispatchQueue.main.async { print("Valid products: \(response.products)") print("Invalid product IDs: \(response.invalidProductIdentifiers)") self.products = response.products if self.products.isEmpty { print("No products found") } else { print("products not empty") for product in self.products { print("Fetched product: \(product.localizedTitle) - \(product.priceLocale.currencySymbol ?? "")\(product.price)") } } } } func debugStoreSetup() { if let receiptURL = Bundle.main.appStoreReceiptURL { if receiptURL.lastPathComponent == "sandboxReceipt" { print("App Store environment: Sandbox") } else { print("App Store environment: Production") } } else { print("No receipt found") } } Could you help identify why my app is not recognizing the Product ID in the sandbox environment? Thank you for your assistance.

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!

I am getting the subject error while simulating Free trial. It is in console. Free trial proceeds but I cant figure out the error meaning. I could not find anything similar on the net or documentation. iOS 18.1 StoreKit2 SwiftUI Has anyone had similar issue that could advise ?

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.

We were facing the same error yesterday and tried many different solutions, but none of them worked. However, today the issue resolved itself and everything is working properly now. The issue we were facing was: #1. not getting any product in didReceive method of storekit. #2. it was working sometimes (i.e. if we try 3 times then 1 time we were getting the product

when we test in app purchase feature in TestFlight, we realize that TestFlight using our real iCloud account in AppStore, but because the app installed from TestFlight, they know it is still "Testing Phase" so they purchase set to FREE. Now im asking about how to test in app purchase for CANCEL SUBSCRIPTION? I can't found in my real iCloud account, either for my sandbox account inside AppStore settings. Please any response will helpful. Thankyou.

The documentation mentions the following: Verify your receipt first with the production URL; then verify with the sandbox URL if you receive a 21007 status code. This approach ensures you don’t have to switch between URLs while your app is in testing, in review by App Review, or live in the App Store. This way, you can use one server environment to handle both Sandbox and Production environments. It is necessary to pass App Review. However, I'm not manually hitting these URLs - I'm using Apple's libraries. Specifically, the environment is used in SignedDataVerifier and AppStoreServerAPIClient. (I can't link to these because, for some reason, the domain apple.github.io is not allowed. The documentation for these is only found there. You can find it quickly by searching these terms and the domain.) Here is how SignedDataVerifier is being used: const verifier = new SignedDataVerifier( appleRootCertificates, APPLE_ENABLE_ONLINE_CHECKS, APPLE_ENVIRONMENT, APPLE_BUNDLE_ID, APPLE_APP_ID ) const verifiedNotification: ResponseBodyV2DecodedPayload = await verifier.verifyAndDecodeNotification(signedPayload) if (!verifiedNotification) { // Failure return } Here is how AppStoreServerAPIClient is being used: const appStoreServerAPIClient = new AppStoreServerAPIClient( SIGNING_KEY, APPLE_IAP_KEY_ID, APPLE_IAP_ISSUER_ID, APPLE_BUNDLE_ID, APPLE_ENVIRONMENT ) const statusResponse: StatusResponse = await appStoreServerAPIClient.getAllSubscriptionStatuses(originalTransactionId, [Status.ACTIVE]) In the source code for SignedDataVerifier.verifyAndDecodeNotification, I can see that it throws a VerificationException(VerificationStatus.INVALID_ENVIRONMENT) error . So for SignedDataVerifier is it as simple as wrapping my code in a try/catch and checking that the error's status code is 21007? I'm unsure about this because if you scroll to the bottom of the linked source code file, you can see the enumeration VerificationStatus, but it's unclear if this member has a value of 21007. The source code for AppStoreServerAPIClient only says that it throws an APIException if a response could not be processed, so I'm not too sure about how to handle this one.

Our application is currently under review, and we are still facing issues because we receive a 401 Unauthorized response from the App Store Connect API when using the production environment. Our app integrates with Chargebee for subscription management, and in production, Chargebee is unable to authenticate with the App Store Server API. This results in a 401 Unauthorized error, preventing the user’s subscription from being synced correctly into our system. Interestingly, the same configuration works in the sandbox environment, but fails in production. We’ve tried authenticating using JWTs generated from multiple keys (including App Store Connect API / Team Keys with both Admin and App Manager access, and also In-App Purchase keys), all with the same result — sandbox access works, production does not. Here is our example code for testing with JWT token: const jwt = require('jsonwebtoken'); const fs = require('fs'); const https = require('https'); const config = { keyId: '<key_id>', issuerId: 'issuer_id', bundleId: 'bundle_id', privateKey: fs.readFileSync('path_to_key') }; const { keyId, issuerId, bundleId, privateKey } = config; const now = Math.floor(Date.now() / 1000); const jwtToken = jwt.sign( { iss: issuerId, iat: now, exp: now + 60 * 10, // 10 minutes is fine for test aud: 'appstoreconnect-v1', bid: bundleId }, privateKey, { algorithm: 'ES256', header: { alg: 'ES256', kid: keyId, typ: 'JWT' } } ); console.log('Generated JWT:\n', jwtToken); // prod const originalTransactionId = '<prod_transaction_id>'; const hostname = 'api.storekit.itunes.apple.com'; // sandbox // const originalTransactionId = '<sandbox_transaction_id>'; // const hostname = 'api.storekit-sandbox.itunes.apple.com' const options = { hostname, port: 443, path: `/inApps/v1/history/${originalTransactionId}`, method: 'GET', headers: { Authorization: `Bearer ${jwtToken}`, 'Content-Type': 'application/json', }, }; const callAppStoreConnectApi = async () => { const req = https.request(options, (res) => { console.log(`\nStatus Code: ${res.statusCode}`); let data = ''; res.on('data', (chunk) => { data += chunk; }); res.on('end', () => { console.log('Response Body:\n', data || '[Empty]'); }); }); req.on('error', (e) => { console.error('Request Error:', e); }); req.end(); }; callAppStoreConnectApi(); With this code, we were able to authenticate successfully in the sandbox environment, but not in production. I read in this discussion: https://developer.apple.com/forums/thread/711801 that the issue was resolved once the app was published to the App Store, but I haven’t found any official documentation confirming this. Does anyone know what the issue could be?

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 don't know how this happened or how to reset this, but I can't test the StoreKit part of my TestFlight app anymore. When I try to retrieve or buy products (IAPs), I get all kinds of strange behavior. I think it is caused by storekitagent thinking the app is in "Xcode sandbox environment". One of the errors from storekitagent looks like this: [51852D62] [LoadSubscriptionStatusTask]: Subscription status request failed with error - Error Domain=NSURLErrorDomain Code=-1003 "A server with the specified hostname could not be found." UserInfo={AMSStatusCode=0, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <468756B3-DA53-4FED-B35C-E093954C27D8>.<1>, NSErrorFailingURLKey=http://localhost:49828/inApps/subscriptions?guid=98DD60024C21&reason=push, _kCFStreamErrorDomainKey=10, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask <468756B3-DA53-4FED-B35C-E093954C27D8>.<1>" ), NSLocalizedDescription=A server with the specified hostname could not be found., NSErrorFailingURLStringKey=http://localhost:49828/inApps/subscriptions?guid=98DD60024C21&reason=push, NSUnderlyingError=0x122f638d0 {Error Domain=kCFErrorDomainCFNetwork Code=-1003 "(null)" UserInfo={_NSURLErrorNWPathKey=satisfied (Path is satisfied), interface: lo0, _kCFStreamErrorCodeKey=-72000, _kCFStreamErrorDomainKey=10}}, _kCFStreamErrorCodeKey=-72000} It looks like it's trying to connect to a local server instead of contacting Apple's App Store servers. I'm on the latest macOS and Xcode. Any help is greatly appreciated:) Thanks!

Hello, About a month ago me and my team allocated a sprint to migrate the App Store Server Notifications service and the StoreKit library from v1 to v2. Once the implementation was completed, we started testing using the sandbox environment (which was supposed to provide greater stability and maturity in v2). The testing session went well, we managed to test various scenarios without noticing any issue (successful payment, failed payment, renewal etc). This week, before doing the production deployment, a final testing session was scheduled. Out of nowhere, we started to encounter all kinds of strange behaviours such as: StoreKit2 error (in Xcode) Received error that does not have a corresponding StoreKit Error: Error Domain=ASDErrorDomain Code=825 "No transactions in response" UserInfo={NSDebugDescription=No transactions in response} Purchase did not return a transaction: Error Domain=ASDErrorDomain Code=825 "No transactions in response" UserInfo={NSDebugDescription=No transactions in response} In some cases the transaction id resulting from the payment was retuned "" or nil, causing our server to raise an exception. Newly created sandbox account that was raising an error that says "there is already a subscription made on this apple id". Delays in the payment processing Today, without doing any code changes, we managed to test all the scenarios without encountering any issue. Due to the oscillating experience we had in the sandbox environment, we are considering postponing the release and maintaining StoreKit 1 for now, but even in this case, the fact that App Store Connect does not offer the possibility of rolling back the Notification Service to v1, causes inconvenience. Has anyone encountered something similar? Is migrating to v2 a good choice?

Hi! My product SKU has been approved for Advanced Commerce API. I successfully receive a purchase pop-up with the correct information. However, I am still having issues with completing the purchase. I always receive Unauthorize error when I confirm the purchase (subscription in my case; see the screenshot). I am using the node.js server library to sign the request. I made sure that the account is a valid account enabled for Sandbox. Logs unfortunately don't indicate any further detail. Thanks for your advice! We've been stuck on this for a while now and would appreciate your help. Marek

We are seeking clarification on the behavior of App Store Server Notifications V2. Summary In our production environment, we received a notification with notificationType: DID_FAIL_TO_RENEW and subtype: GRACE_PERIOD. However, the gracePeriodExpiresDate field in the payload was null. We understand this notification indicates that a user's subscription has entered a grace period. The null value for its expiration date is unexpected, and we are looking for an official explanation of this behavior and the correct way to handle it. The Scenario Here are the details of the notification we received: Notification Type: DID_FAIL_TO_RENEW Notification Subtype: GRACE_PERIOD Environment: Production Upon decoding the signedRenewalInfo JWS from the responseBodyV2, we found that the gracePeriodExpiresDate field inside the JWSRenewalInfoDecodedPayload was null. The notificationUUID for this event was in the format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. Our Implementation and its Impact Our backend is designed to ensure service continuity during a grace period, as recommended in the documentation. Current Logic: Receive the DID_FAIL_TO_RENEW / GRACE_PERIOD notification. Extract the gracePeriodExpiresDate. Extend the user's subscription expiration date in our database to match this date. Because the gracePeriodExpiresDate was null in this case, our logic failed, creating a risk of service interruption for the user. Context and Investigation We have performed the following checks: App Store Connect Settings: We have confirmed that Billing Grace Period is enabled for the relevant subscription group. Sandbox Environment: We have been unable to reproduce this scenario in the Sandbox. User Context: We believe the user in this case was experiencing a failed payment when attempting to renew for the first time after a free trial period. Questions To ensure we handle this scenario correctly, we would appreciate clarification on the following points: Conditions for Null: Under what specific conditions does a DID_FAIL_TO_RENEW notification with a GRACE_PERIOD subtype contain a null gracePeriodExpiresDate? Expected Behavior: Is this null value an expected behavior for certain scenarios, such as the first failed renewal after a free trial? Best Practice: If this is an expected behavior, what is the correct way to handle it? How should our backend interpret a null gracePeriodExpiresDate to ensure service continuity for the user?

We are experiencing an Unknown Error (error code 0) when testing purchases in the Apple Sandbox environment. The error does not occur every time, but it fails with an Unknown Error in approximately 8 out of 20 attempts. Due to this issue, our app is failing to pass Apple’s review. Issue Details This issue only occurs in the Apple Sandbox environment. After attempting a purchase, the Apple payment API returns SKPaymentTransaction Unknown Error. Returned error code: SKErrorUnknown (error.code 0). This problem is preventing us from conducting proper payment tests and getting approval from Apple. Would it be possible to receive support or any solutions for this issue?

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 ?

the email say this notification type will be available to you in production beginning May 27, 2025, and you can test it in sandbox now. but i didn't receice this notification yet

A purchase can result in success with verificationResult .unverified. Is there a list of reasons for which the transaction might be unverified and how should i handle it in my app? From my understanding, a successful unverified transaction means the user has already paid for the purchase. So, do i just ignore the unverified transaction or do i provide content to the user anyways?

We are running auto-renewing subscriptions with StoreKit2 and the “get all subscription statuses” API is behaving unexpectedly. record the originalTransactionId from the iPhone to the server side when purchasing a subscription with Storekit2. query the get all subscription statuses API from the server side with the originalTransactionId recorded. get all subscription statuses returns a response, but there is no data in the response that matches the originalTransactionId. I have an error on my system because I have built my system on the assumption that all subscriptions including originalTransactionId will be returned.

Appium can't see any locators of 'Sandbox' view in case of purchase page automation try. iOS 18.x. On version 17.x the elements could be found

Problem Description: 1、I have two sandbox accounts from different countries. Account A is from Mainland China (CHN), and Account B is from the United States (USA). When I switch the sandbox account from Account A (CHN) to Account B (USA) in the system settings and restart the app, the value of SKPaymentQueue.defaultQueue.storefront.countryCode always returns "CHN" instead of the expected "USA". 2、This issue only occurs on iOS 18.2 and above. 3、On the same device running iOS 17.5.1, the behavior is correct. However, after upgrading the system to iOS 18.3.2, the error occurs. 4、In the sandbox environment, although SKStorefront.countryCode returns the wrong value, the currency type for Apple's in-app purchase is correct when initiating the payment. 5、The issue only exists in the sandbox environment and does not occur in the App Store-downloaded package. Demo Code: - (IBAction)clickButton:(id)sender { NSString *appStoreCountryCode3 = SKPaymentQueue.defaultQueue.storefront.countryCode; NSLog(@"%@",appStoreCountryCode3); } Demo Testing Steps and Results: 1、Sandbox Account A (China) will print "CHN". 2、Go to Settings - Developer - (at the bottom) SANDBOX APPLE ACCOUNT, and switch to another sandbox account B (USA). 3、Restart the Demo App. 4、Print results: iOS 17.5.1: "USA" ✅ → Upgrade the system of the same device to iOS 18.3.2 → "CHN" ❌ iOS 18.2.1: "CHN" ❌ iOS 18.3.1: "CHN" ❌ iOS 18.3.2: "CHN" ❌ Possible Clues: Starting with iOS 18.2, Apple changed the entry point for setting up sandbox accounts, which introduced this bug. It seems that when users switch sandbox accounts on iOS 18.2, Apple engineers forgot to notify the SKStorefront class to update the countryCode value. Before iOS 18.2: Settings - App Store - Sandbox Account iOS 18.2 and later: Settings - Developer - (at the bottom) Sandbox Account Although it doesn't affect the App Store package, it does impact our development and testing process. We hope this issue can be fixed in future versions. Thank you!
