Issue with UPI IAP Transactions Stuck in Pending State and No Rewards Granted
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!

App Store Server API JWT Authentication Issue
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.

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

Does the Apple Store support variable recurring payments like Stripe?
Stripe offers variable payment structures, also known as "irregular recurring payments," which include: Usage-based billing: Charges amounts based on usage during the billing cycle (e.g., minutes used or energy consumed). Quantity-based billing: Charges a pre-agreed amount based on quantity (e.g., number of users in a subscription). Is it possible to implement this type of billing in the Apple Store for apps? How would variations in amounts be handled?

SubscriptionStoreView Localization Error
Hello! The localization isn't working when using SubscriptionStoreView. The app hasn't been published yet. The subscription has been created and localization strings have been added. Status - ready to submit. Testing environment: Sandbox When calling SubscriptionStoreView, the debug console shows this error: GenerativeModelsAvailability.Parameters: Initialized with invalid language code: ru-RU. Expected to receive two-letter ISO 639 code. e.g. 'zh' or 'en'. Falling back to: ru Despite this, the subscription interface appears in English when Russian is expected. I don't use any locale setting for ru-RU anywhere in my code. The test device's region is set to Russia, and the language is Russian. Any help would be appreciated.

IAP Phantom Error
Trying to test IAP in sandbox. I created the test group and tester accounts. Accepted the invite downloaded the app. Signed into to sandbox in settings with the tester account. In app the purchases are failing and throwing my catch error message product couldn't be found. I decided to test it from settings/ sandbox/ manage/ initiate purchase/ but I've been getting "can't complete transaction. Something went wrong, ant this transaction couldn't be completed. Try again later" since last week. I reached out to dev support over the phone then email and they couldn't or wouldn't provide assistance. I asked my senior at work she took a look at it and confirmed I created the IAP correctly and that my sandbox account could make test purchases in apps she make but couldn't get mine to work. The storekit test work fine in xcode I just don't know what to do now.

Delete Offer Codes
Regarding the offer codes in https://developer.apple.com/help/app-store-connect/manage-subscriptions/set-up-offer-codes, I set up some incorrect offer codes by mistake. Currently, I can only deactivate it but I can't delete it. Is it possible to let me delete the incorrect offer codes due to the below reasons? Thank you. I can't recreate the offer code due to error message This reference name is or has been used by another offer in this subscription group. When I use the offer code redemption view in https://developer.apple.com/documentation/SwiftUI/View/offerCodeRedemption(isPresented:onCompletion:), it shows all the deactivated offer codes. I don't want them to be displayed in the page.

StoreKit Products Load After Rebuild But Not on Fresh Install (iOS/SwiftUI)
Problem: I'm implementing StoreKit 2 in my SwiftUI app. Products load successfully when I rebuild in Xcode, but on a fresh install, Product.products(for:) returns an empty array. The paywall shows "Unable to load pricing." Setup: Using StoreKit Configuration File ( .storekit ) for testing Product IDs match exactly between config and code: com..premium.lifetime (non-consumable) com..premium.monthly (auto-renewable subscription) com.****.premium.yearly (auto-renewable subscription) StoreKitManager is a @MainActor singleton with @Published properties What I've Tried: Initial delay before loading - Added 1-second delay in init before calling loadProducts() Product ID verification - Confirmed IDs match exactly between StoreKitConfig.storekit and code Retry logic with exponential backoff - Implemented 3 retry attempts with 0.5s/1s/1.5s delays Multiple calls to updatePurchasedProducts() - Called twice after initial load Verified StoreKit configuration - File is properly added to project, has valid product definitions Code Structure: swift @MainActor final class StoreKitManager: ObservableObject { static let shared = StoreKitManager() @Published private(set) var products: [Product] = [] private init() { updateListenerTask = listenForTransactions() Task { try? await Task.sleep(nanoseconds: 1_000_000_000) await loadProducts() // Returns empty on fresh install await updatePurchasedProducts() } } } Observations: ✅ Works perfectly after Xcode rebuild ❌ Fails on fresh app install (simulator & device) ❌ Product.products(for:) returns empty array (no error thrown) ✅ StoreKit configuration file is valid and properly configured Question: Why does StoreKit need a rebuild to recognize products? Is there a proper initialization sequence I'm missing for fresh installs? Environment: Xcode [Version 26.0 beta 7] iOS [IOS +17.0] Testing with StoreKit Configuration File

Promotional offer does not work, gave error code 3903
I tried to apply a promotional offer to a subscribed user. When I tested it in the Sandbox environment, it did not show the promotional payment popup but returned a “restored” status. However, when I tested it in the Xcode environment, it correctly displayed the payment popup, but after I tapped the Subscribe button, it showed an “Unable to Purchase” popup like this: And in the console I could see this error: Received error that does not have a corresponding StoreKit Error: Error Domain=AMSErrorDomain Code=305 "Server Error The server encountered an error" UserInfo={AMSURL=http://localhost:56862/WebObjects/MZBuy.woa/wa/inAppBuy, AMSDescription=Server Error, NSDebugDescription=Server Error The server encountered an error, AMSServerErrorCode=3903, AMSStatusCode=200, AMSServerPayload={ "cancel-purchase-batch" = 1; dialog = { defaultButton = ok; explanation = "Contact the developer for more information.\n\n[Environment: Xcode]"; initialCheckboxValue = 1; "m-allowed" = 0; message = "Unable to Purchase"; okButtonString = OK; }; dsid = 17322632127; failureType = 3903; jingleAction = inAppBuy; jingleDocType = inAppSuccess; pings = ( ); }, AMSFailureReason=The server encountered an error} Could someone help me resolve this issue? I’ve been struggling with it for two days and feeling exhausted...

In-App Subscriptions Not Fetching in Sandbox or Production (expo-iap / React Native / Bare Workflow)
Hi everyone, I’m encountering an issue with my in-app subscriptions setup. When I test using the StoreKit configuration file in Xcode, everything works correctly — the subscriptions are fetched and I can simulate purchases without any issues. However, when I switch to the Sandbox or Production environment, my app fails to fetch the available products from Apple’s servers. The call to fetchProducts (from the expo-iap library) returns an empty array. Here’s some context about my setup: Framework: React Native (Expo Bare Workflow) Library: expo-iap Products: Auto-renewable subscriptions StoreKit Configuration: Synced with App Store Connect Status: Subscription Plans are approved in App Store Connect I’ve verified the following: The product identifiers in code match exactly with those in App Store Connect. The app is signed with the correct bundle ID. I’m testing with a Sandbox account (logged in via Settings -> Developer -> Sandbox Tester Account). Despite this, the response from Apple’s servers still contains an empty array. Has anyone experienced something similar with expo-iap or in general when moving from StoreKit configuration to Sandbox/Production? Any suggestions on what else I could check or common pitfalls I might be missing? Thanks in advance!

Hi All i have developed an app but when I go to download the paywall appears as it’s subscription only but it shows no prices for the subscription I get an endless swirl. I checked the product id etc and it’s correct but the subcription on my App Store Connect shows as approved. is there another status it needs to reach before it becomes like like ready for sale? https://apps.apple.com/gb/app/gameaware-pro/id6751592563

No notification on declined pending transaction
I'm working on adding a single Non-Consumable In-App purchase to my app. Essentially a "try before you buy" type thing. Limited functionality unless the app is purchased. I am currently testing this using Xcode and the Manage StoreKit Transactions window. So far most everything appears to be working except for declined pending transactions. If I set Ask to Buy to Enabled, the Ask Permission (for parent or guardian) dialog appears. After pressing the Ask button, I see a transaction listed as Pending Approval. If I Approve the transaction, then my app is notified and all is well. However, if I Decline the transaction then my app is not notified. Is that normal? Also, how do I (i.e. the app) know that there is a pending transaction?

subscriptionPeriod.unit returns both .week AND .day for weekly subscriptions?
After creating a new weekly subscription option, I get inconsistent results for subscriptionPeriod. In local testing with a synced or a un-synced StoreKit file I am getting unit == .week (as expected) whereas in TestFlight I am getting unit == .day. This makes unit.localizedDescriptionsomewhat unusable in the paywall. Am I missing something? Or is this bug or a limitation of StoreKit and/or TestFlight and/or newly created subscription options? Affected code (in a custom SubscriptionStoreControlStyle): private func priceDisplay(for pickerOption: Configuration.PickerOption) -> String { var result = "" if pickerOption.introductoryOffer != nil { result += NSLocalizedString("then", comment: "") + " " } result += pickerOption.displayPrice if let unit = pickerOption.subscriptionPeriod?.unit { result += " / " + unit.localizedDescription } return result } private func percentageSaved(for pickerOption: Configuration.PickerOption, allOptions: [Product]) -> Int? { guard let subscriptionPeriod = pickerOption.subscriptionPeriod, subscriptionPeriod != .weekly else { return nil } let weeklyOption = allOptions.first { otherOption in otherOption.subscription?.subscriptionPeriod == .weekly } guard let weeklyOption, weeklyOption.price > 0 else { return nil } let percentageSaved = 100 - (pickerOption.price / (weeklyOption.price * 52)) * 100 return Int((percentageSaved as NSNumber).doubleValue) }
