iOS Storekit2 Appstore production environment, some user feedback in app purchase faliure, What our log records is StoreKitError.unknown，please How to solve problem, thanks

I'm trying to understand the IAP development process. I created my first Product on App Store Connect and am trying to build my app to use it. However it keeps failing with "Invalid product ID.". From what I've read, this is because the product has not yet gone through review. But what I don't understand is, of course it hasn't gone through review yet, because trying to use it in any capacity fails, even though I'm using a real physical device and using a Sandbox User. Is this the correct workflow? It seems very backwards that I have to submit the product for review, even before I know how it's going to be used. I'm still building the screen for the product page, and haven't even started touching any backend APIs, yet it's asking for screenshots. Am I misunderstanding something here?

I am shown as being subscribed to our service in the Subscriptions list in settings yet when going to the Storekit2 page in my app it shows me as NOT being subscribed and is unresponsive. I select Restore Subscription, that grays briefly, asks for a password, then returns to blue and nothing else happens. Bouncing back and forth between monthly and yearly likewise gives no response. The Transaction.currentEntitlements seems to be empty so it thinks the user is not subscribed. I have unsubscribed, and resubscribed via the Settings page to no avail.

Hi all, I’m testing Subscription in my Flutter app on a real iOS device (iPhone 16 Pro with iOS 18) via TestFlight. I’ve set everything up as required, but I still get this error: flutter: Found products: [] If everything works perfectly when StoreKit configuration is used in Xcode, but not via TestFlight. All my Subscriptions are approved with the same ID.

When I test subscibe in sandbox，IOS says this transaction need to request parent’s approval。But this is a sandbox account，it don't have any family members

Hi, thanks for reading my question. I need help with some odd behaviour with product.purchase() not triggering a confirmation dialog after a subscription has expired and trying to purchase it again. Seeing this in iOS 16.2 and 15.7.2 (haven't tried any other versions) on actual devices, not in simulator. I'm using a sandbox user on the sandbox environment (not using the local store kit config file testing option). Using a newly created sandbox user, first subscription purchase goes through just fine, dialog box pops up, login with sandbox user, get confirmation of purchase and then Transaction.currentEntitlements has one item as expected. It auto renews for 12 times (each time Transaction.currentEntitlements contains the correct results) and then expires, as expected for sandbox. Transaction.currentEntitlements is then also empty, as expected. All good so far. Now I want to test purchasing it again...Call product.purchase() again to renew/start a new subscription and nothing happens, no confirm purchase dialog box pops up at all. The purchase function simply exits BUT returns success (as in the following gets called) but in self.updatePurchasedProducts(), Transaction.currentEntitlements is empty. case let .success(.verified(transaction)):      // Successful purchase       await transaction.finish()      await self.updatePurchasedProducts() if I instead go to Settings->App Store->Sandbox User-> Manage Subscriptions and renew the subscription there, instead of in my app, then Transaction.currentEntitlements has a new entry and all is good again. Alternatively, if I create yet another new sandbox user and logout of the old one I was using, I am once again able to purchase from within the app, so .purchase() once again works as normal. Is there something I am missing about expired subscriptions and trying to purchase them again in the app? Is this a sandbox issue and in production I'll have no problem? The sandbox user has purchasing enabled in Settings->App Store. I've also tried calling AppStore.sync() (which is in my "Restore Purchase" button) before calling product.purchase() after the subscription stops renewing, expires and this issue comes up, doesn't resolve it. Also have a less important question, the initial call to product.purchase(), the one that works as expected, has a bit of a delay before the confirmation dialog pops up, a few seconds, which will probably result in the user clicking the buy button again thinking it didn't work. Is a bit of a delay normal for sandbox? Will it be ok in production? When it fails, and I have to renew in Settings->AppStore->Sandbox user, there's also a bit of a delay after I return to my app, 5-15 or so seconds, before the transaction observer fires and currentEntitlements is checked again, is there a way to reduce this delay? Thank you!

Issue Description I am experiencing persistent 401 Unauthorized errors when attempting to access the App Store Server API using JWT authentication. Despite following Apple's documentation and regenerating keys, I am unable to successfully authenticate. Implementation Details I'm implementing JWT authentication for the App Store Server API to retrieve transaction information from the following endpoint: https://api.storekit.itunes.apple.com/inApps/v1/transactions/{transactionID} My JWT generation code (in PHP/Laravel) follows Apple's documentation: php$kid = '6W6H649LJ4'; $header = [ "alg" => "ES256", "kid" => $kid, "typ" => "JWT" ]; $iss = 'b8d99de7-b43b-4cbb-aada-546ec784e249'; // App Store Connect API Key Issuer ID $bid = 'com.gitiho.learnCourse'; // Bundle ID $payload = [ "iss" => $iss, "iat" => time(), "exp" => time() + 3600, "aud" => "appstoreconnect-v1", "bid" => $bid ]; $pathFileAuthKeyP8 = "AuthKey_6W6H649LJ4.p8"; $contentFileAuthKey = \File::get(base_path($pathFileAuthKeyP8)); $alg = "ES256"; $jwt = \Firebase\JWT\JWT::encode($payload, $contentFileAuthKey, $alg, null, $header); Steps Taken to Troubleshoot Verified that the Issuer ID is correct and in UUID format Confirmed that the Key ID matches the private key filename Regenerated the key with proper App Store Server API permissions Ensured the private key file is properly formatted with correct headers and footers Verified that the JWT is being properly encoded using the ES256 algorithm Confirmed the bundle ID is correct for our application Checked that the API endpoint URL is correct Additional Information This implementation previously worked correctly We started experiencing 401 errors recently without changing our implementation We are using the Firebase JWT library for PHP to encode the JWT Request Could you please help identify what might be causing these authentication failures? Is there any recent change in the authentication requirements or endpoint URLs that might be affecting our integration? Thanks for support me.

Background We sell a suite of iPadOS/macOS apps that share a single auto-renewable subscription using this architecture. Per “Offering a Subscription Across Multiple Apps” we require users to sign in before purchasing so we can propagate the entitlement and avoid duplicate subscriptions across apps. To enforce that sign-in step we plan to turn off Streamlined Purchasing in App Store Connect. Question We also want to distribute subscription offer codes (for promotion, retention, appeasing dissatisfied customers, etc.). After Streamlined Purchasing is turned off, will customers still be able to redeem offer codes outside the app (App Store “Redeem Code” UI or redemption URL)? If outside-app redemption remains possible, it bypasses our sign-in gate and could let the same customer buy the suite twice (once via each app). Is there an approved method to limit offer-code redemption to the in-app flow only, or otherwise prevent such duplicate subscriptions? If no such limitation exists, what best-practice workaround does Apple recommend for multi-app suites that must turn off Streamlined Purchasing yet still wish to use offer codes without duplication risk? Environment StoreKit 2; server-side receipt validation & cross-app entitlement propagation. Apps support the in-app presentCodeRedemptionSheet flow. We expect to use both one-time-use and custom offer codes.

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?

Hi everyone, We operate an online game where all in-app assets are stored server-side and require a logged-in account (no device binding). I’d like guidance on four areas: Do we really need deviceVerification / deviceVerificationNonce? – Because every purchase is tied to an account and we enforce a global transactionId UNIQUE constraint, replay or cross-account reuse appears infeasible. Under these conditions, is omitting device verification acceptable, or are there situations where Apple still recommends it? Permanent rate-limit increase for the App Store Server API – During anniversary events we saw bursts of ~18 000 requests per hour, breaching the current hourly cap on the App Store Server API (verifyTransaction, getNotificationHistory, etc.). Is there a formal process to request a long-term rate-limit expansion (or an alternative tier) from Apple? When is an App Store Server API call required for a StoreKit 2 jwsRepresentation? Docs say “call the API if you’re unsure,” but there’s no clear cut-off. Because we fully validate the JWS signature plus the entire certificate chain (including CRL/OCSP checks) on our server, local cryptographic validation seems sufficient for consumables. For subscriptions we still plan to hit the API to fetch the latest status. Does this separation match Apple’s best practice? If Apple does recommend hitting the API for consumables as well, we’d like a concrete rule of thumb—e.g. “if the item price is USD 50 or higher, always use the API.” Is establishing such thresholds consistent with Apple’s intent? Refund-risk reduction from Send Consumption Info – Adapty reports a 40–60 % refund-rate drop for subscriptions when using Send Consumption Info (blog reference). Can we expect similar reduction for consumable IAP in social/online games? Any real-world results would be helpful. Thanks in advance for any guidance!

Hello everyone! We are observing a significant number of failures in the fetch of the products with StoreKit1, meaning that in a completely random way, some product identifiers are considered invalid in the response that we receive from Apple, and after some minutes these products are considered once again valid. The issue started on Thursday 04/24 around 12.00 am (UTC + 02.00) and from our dashboard we can clearly see the trend of these failures has some spikes at precise times. I am attaching a view that we use for monitoring purposes showing this trend, considering the data of this week. We are noticing this problem on multiple developer accounts and on multiple apps, which is leading us to think it could be an issue in the Apple backend processing the request. In our case, the apps are not launched correctly until all the products are fetched, and therefore the impact of this problem is very high. Is anyone experiencing something similar or do you have logs which allows you to identify such issues? The issue happens only in production, while in debug and TestFlight environment everything works well. Thank you for your support

Hi everyone, We’ve encountered an issue in some of our games where IAP purchases made using UPI are going into a pending state. Since these purchases are for consumable items, the rewards are not granted at the time of purchase. Even after the transactions are eventually confirmed, the rewards still aren't received. We tested this with two separate UPI transactions, and both resulted in the same pending state issue. Interestingly, when we tried making a purchase using Apple Wallet afterward, the transaction completed successfully on the first attempt, without any pending state. This issue seems specific to UPI transactions. Could anyone help us understand why this is happening or if there’s a recommended way to handle such cases? Thanks in advance!

Currently, over the xcode environment to do the testing of product subscriptions through appstore are working correctly using the storeKit. When deployed in testflight to do the testing over the integration environment, the store response times are being excessively high, in excess of 20 minutes. This behavior is not replicated on Xcode, and is happening on recent versions uploaded to testflight, as earlier versions that were already tested and are currently in production. In addition the communication between the appstore webhook and the BE is also failing in this environment. It is being blocked to generate any test to be able to launch to production.

works perfectly on android but doesn't work at all on IOS and i have used the same bundle id and product ids on both stores. The error that i get on IOS is : "IAP initialization failed: NoProductsAvailable - No Product returned from store" Here are the things that i've done: Created an App ID on the apple developer portal with the correct capabilities I have enabled the correct capabilities on the xcode project Unity Framework is embed and signed, Storekit (do not embed) In singin and capabilities in-app purchases is there I am using testflight to submit the app with a distribution certificate that appears to be valid I've checked the the bundle identifier and it's the same everywhere (unity project, xcode project, App ID) All of the products are cleared for sale and are in the status "ready to submit" I always uninstall the old app version before testing the new one My banking updates are still processing does this effect TestFlight IAP Paid Apps Agreement is in Pending User Info state does this effect also I still haven't filled out the tax forms, so I'm wondering if I need to complete them before my app's in-app purchases (IAPs) work in TestFlight.

Hi All, We are trying to integrate Promotional Offer in our app, We have a React Native app and are using react-native-iap for handling our in app purchases, as per the documentation we are generating signature in our BE and passing the proper details to the function as well, but for subscription request which have offer applied we are getting the apple pop up properly as well with offer details but when trying to subscribe it gives us SKErrroDomain: 12, for subscription without applying offer the subscription goes through but when we apply the offer we get the above error. Our app is currently in Development Stages and has not been sent for review sam for our subscription plans as well. Please let me know what could be the probable cause for this and help us resolve the issue. This is the code snippet of ours for the front end : export const buySubscription = async (subscriptionData: any) => { try { if (subscriptionData.offer_id) { const response = await getSubscriptionSignature( subscriptionData.productId, subscriptionData.offer_id, ); const offerData = response?.data; const offer = { identifier: offerData?.offer_id, keyIdentifier: offerData?.key_id, nonce: offerData?.nonce, signature: offerData?.signature, timestamp: Number(offerData?.timestamp), }; await requestSubscription({ sku: subscriptionData.productId, withOffer: offer, }); } else { await requestSubscription({ sku: subscriptionData.productId }); } } catch (err) { logger.error('Subscription error: ' + JSON.stringify(err)); throw err; } }; and

We are currently integrating In-App Purchases for our app and have configured App Store Server Notifications (v2) in the Sandbox environment. During testing, we observed the following issue: When a transaction is cancelled, declined, or pending (e.g., Ask to Buy flows or authorization pending), No App Store Server Notification is sent to our webhook endpoint. We only receive webhook events where the status is "purchased". This becomes a critical problem for us because our backend must accurately track transaction states including failed and pending purchases, especially for wallet top-up use cases. Additionally, we tried mocking failed transactions (via Xcode local environment and turning off In-App Purchases from Developer Settings) to simulate a technical failure scenario. Even in these cases, no webhook notification was received when the purchase failed server-side. Is it expected behavior in Sandbox that only successful transactions ("purchased") trigger webhooks? Are failed or pending transactions suppressed in Sandbox intentionally? Will webhook behavior be different in Production (i.e., will we receive webhook notifications for failures there)? Is there any extra configuration or entitlement needed to fully test failure scenarios via webhooks in Sandbox?

Hi all, I am adding the following StoreKit 2 code to my app, and I don't see anything in Apple's documentation that explains the unverified case. When is that case exercised? Is it when someone has tampered with the app receipt? Or is it for more mundane things like poor network connectivity? // Apple's docstring on `shared` states: // If your app fails to get an AppTransaction by accessing the shared property, see refresh(). // Source: https://developer.apple.com/documentation/storekit/apptransaction/shared var appTransaction: VerificationResult<AppTransaction>? do { appTransaction = try await AppTransaction.shared } catch { appTransaction = try? await AppTransaction.refresh() } guard let appTransaction = appTransaction else { AppLogger.error("Couldn't get the app store transaction") return false } switch appTransaction { case .unverified(appTransaction, verificationError): // For what reasons should I expect this branch to be entered in production? return await inspectAppTransaction(appTransaction, verifiedByApple: false) case .verified(let appTransaction): return await inspectAppTransaction(appTransaction, verifiedByApple: true) } Thank you, Lou
