Can I ask user to share his/her email id while doing
We sell magazines through a third party app platform called Pocketmags and our website. The magazines have Print, Digital and Combo options available for purchase. Also, this third party app provides the platform to read the digital version of the magazines. Once a user buys a subscription on the website, he/she receives the email with the login information on PocketMags, where he registers his login details and can start reading his subscription. With us, the customer shares his billing/shipping address along with their email id while they make payment. Now we have our own app where through which we want to sell these magazines and have to integrate In-App purchase for selling these digital subscriptions. How do we send the 3rd party subscription access details on email to the user if they do in app purchase?

SKErrorDomain Code 2 Problem
We are facing a serious issues with in app purchases in our app. We offer 3 IAP: auto-renewable subscription 1W, auto-renewable subscription 1Y, non-consumable one-time purchase (LifeTime access) In our case 90-95% of transactions fail and we mostly get SKError code=2 . Sometime purchase fails several times for the same user so it’s very hard to believe that user intentionally cancels transaction for the same product 4 or even 5 times in a row. It happens regardless iOS version, device model, our app version. We've checked multiple threads with the same issue but coudn't find any solution. We do not offer any promotions, product identifiers are valid... Some users are able to make a purchases without any issues.

Invalid currency symbol
Strange issue with currency display in subscription products Hi everyone, I'm facing a strange issue in my app where I use a subscription-based in-app purchase model. The products I created in App Store Connect are all in "Approved" status. I've tested with both RevenueCat and StoreKit, but the result is the same. Here are the products being loaded: Product loaded: weekly_product_id Display name: Weekly Pro Description: Weekly Pro Subscription Price: ₺229,99 Product loaded: annual_product_id Display name: Annual Pro Description: Annual Pro Subscription Price: ₺1.799,99 Even though I can see the correct prices and currency (Turkish Lira) in the Xcode debug console, on my real device the currency appears as Philippine Peso, as shown in the attached screenshot. Interestingly, in the iOS simulator, it's displayed in USD. I've double-checked and my device's region settings are set to Turkey. Any ideas on what could be causing this? And more importantly, how can I fix it? Thanks in advance!

StoreKit2 Subscription Verification
My question is simple, I do not have much experience in writing swift code, I am only doing it to create a small executable that I can call from my python application which completes Subcription Management. I was hoping someone with more experience could point out my flaws along with giving me tips on how to verify that the check is working for my applicaiton. Any inight is appreciated, thank you. import Foundation import StoreKit class SubscriptionValidator { static func getReceiptURL() -> URL? { guard let appStoreReceiptURL = Bundle.main.appStoreReceiptURL else { print("No receipt found.") return nil } return appStoreReceiptURL } static func validateReceipt() -> Bool { guard let receiptURL = getReceiptURL(), let receiptData = try? Data(contentsOf: receiptURL) else { print("Could not read receipt.") return false } let receiptString = receiptData.base64EncodedString() let validationResult = sendReceiptToApple(receiptString: receiptString) return validationResult } static func sendReceiptToApple(receiptString: String) -> Bool { let isSandbox = Bundle.main.appStoreReceiptURL?.lastPathComponent == "sandboxReceipt" let urlString = isSandbox ? "https://sandbox.itunes.apple.com/verifyReceipt" : "https://buy.itunes.apple.com/verifyReceipt" let url = URL(string: urlString)! let requestData: [String: Any] = [ "receipt-data": receiptString, "password": "0b7f88907b77443997838c72be52f5fc" ] guard let requestBody = try? JSONSerialization.data(withJSONObject: requestData) else { print("Error creating request body.") return false } var request = URLRequest(url: url) request.httpMethod = "POST" request.httpBody = requestBody request.setValue("application/json", forHTTPHeaderField: "Content-Type") let semaphore = DispatchSemaphore(value: 0) var isValid = false let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil, let jsonResponse = try? JSONSerialization.jsonObject(with: data) as? [String: Any], let status = jsonResponse["status"] as? Int else { print("Receipt validation failed.") semaphore.signal() return } if status == 0, let receipt = jsonResponse["receipt"] as? [String: Any], let inApp = receipt["in_app"] as? [[String: Any]] { for purchase in inApp { if let expiresDateMS = purchase["expires_date_ms"] as? String, let expiresDate = Double(expiresDateMS) { let expiryDate = Date(timeIntervalSince1970: expiresDate / 1000.0) if expiryDate > Date() { isValid = true } } } } semaphore.signal() } task.resume() semaphore.wait() return isValid } }

Inquiry regarding StoreKit Messages for Free Trial Conversion and Recurring Payment Consent in South Korea
Dear Apple Developer Support, Our iOS application offers subscriptions with a free trial period. We understand that in South Korea, due to local subscription regulations, users must explicitly provide consent for recurring payments before the subscription converts from a free trial to a paid period. We have the following questions regarding how StoreKit handles this scenario: When a free trial is about to convert to a paid subscription for a user in South Korea, does StoreKit send a StoreKit.Message (or SKStorefront.Message) to the application to obtain the required consent for recurring payments? If such a message is sent, would the Reason for this message be StoreKit.Message.Reason.priceIncreaseConsent, or would it be another specific reason related to initial recurring payment consent after a trial? If our application receives such a message and we choose to defer its display, what is the maximum recommended or permissible deferral period? Is it possible to save the data of a received StoreKit.Message and display it to the user at a later time, for instance, after the application has been closed and subsequently reopened? Are there any best practices or limitations regarding this? We need this information to ensure our application correctly handles these consent requirements in compliance with South Korean policies and provides a smooth user experience. Thank you for your guidance.

Inconsistent appTransactionId in Transaction History
Issue Description When using the App Store Server API endpoint GET v2/history/{transactionId} to retrieve transaction history for a specific transaction, I'm observing unexpected changes in the appTransactionId field across related transactions in the same subscription group. Important Context: This is a "clean" auto-renewable subscription with no user intervention - the user has had continuous auto-renewals without any upgrades, downgrades, cancellations, or resubscriptions. The subscription has been renewing automatically and successfully throughout the entire period. API Call GET v2/history/1000000000000001 Response Data The API returns the following transaction history, where I notice the appTransactionId values are inconsistent across what should be a straightforward auto-renewal sequence: Note: The data below has been sanitized for privacy protection (IDs, bundle identifiers, etc. have been replaced with example values), but the logical relationships, date sequences, and the core issue remain identical to the original data. Array ( [0] => Array ( [transactionId] => 1000000000000001 [originalTransactionId] => 1000000000000001 [webOrderLineItemId] => 1000000000000001 [bundleId] => com.example.myapp [productId] => MonthlySubscription [subscriptionGroupIdentifier] => 20000000 [purchaseDate] => 1743784032000 [originalPurchaseDate] => 1743784034000 [expiresDate] => 1746376032000 [quantity] => 1 [type] => Auto-Renewable Subscription [inAppOwnershipType] => PURCHASED [signedDate] => 1751868174651 [environment] => Production [transactionReason] => PURCHASE // Original purchase [storefront] => USA [storefrontId] => 143441 [price] => 100000 [currency] => USD [appTransactionId] => 700000000000000001 // Different value ) [1] => Array ( [transactionId] => 1000000000000002 [originalTransactionId] => 1000000000000001 [webOrderLineItemId] => 1000000000000002 [bundleId] => com.example.myapp [productId] => MonthlySubscription [subscriptionGroupIdentifier] => 20000000 [purchaseDate] => 1746376032000 [originalPurchaseDate] => 1746347349000 [expiresDate] => 1749054432000 [quantity] => 1 [type] => Auto-Renewable Subscription [inAppOwnershipType] => PURCHASED [signedDate] => 1751868174651 [environment] => Production [transactionReason] => RENEWAL // First auto-renewal [storefront] => USA [storefrontId] => 143441 [price] => 100000 [currency] => USD [appTransactionId] => 700000000000000002 // Same for renewals ) [2] => Array ( [transactionId] => 1000000000000003 [originalTransactionId] => 1000000000000001 [webOrderLineItemId] => 1000000000000003 [bundleId] => com.example.myapp [productId] => MonthlySubscription [subscriptionGroupIdentifier] => 20000000 [purchaseDate] => 1749054432000 [originalPurchaseDate] => 1749025657000 [expiresDate] => 1751646432000 [quantity] => 1 [type] => Auto-Renewable Subscription [inAppOwnershipType] => PURCHASED [signedDate] => 1751868174651 [environment] => Production [transactionReason] => RENEWAL // Second auto-renewal [storefront] => USA [storefrontId] => 143441 [price] => 100000 [currency] => USD [appTransactionId] => 700000000000000002 // Same as previous renewal ) [3] => Array ( [transactionId] => 1000000000000004 [originalTransactionId] => 1000000000000001 [webOrderLineItemId] => 1000000000000004 [bundleId] => com.example.myapp [productId] => MonthlySubscription [subscriptionGroupIdentifier] => 20000000 [purchaseDate] => 1751646432000 [originalPurchaseDate] => 1751617840000 [expiresDate] => 1754324832000 [quantity] => 1 [type] => Auto-Renewable Subscription [inAppOwnershipType] => PURCHASED [signedDate] => 1751868174651 [environment] => Production [transactionReason] => RENEWAL // Third auto-renewal [storefront] => USA [storefrontId] => 143441 [price] => 100000 [currency] => USD [appTransactionId] => 700000000000000002 // Same as previous renewals ) ) Questions Is this behavior expected? Should the appTransactionId change between the original purchase and subsequent renewals within the same subscription group, especially when there are no user actions (upgrades/downgrades/cancellations/resubscriptions)? What determines the appTransactionId value? The documentation doesn't clearly explain when this identifier might change or what triggers a new value. This is particularly puzzling since this is a straightforward auto-renewal scenario. How should we handle this in our backend logic? Should we treat transactions with different appTransactionId values as separate entities, or should we rely on originalTransactionId for grouping related subscription transactions? Is this a known issue? We've seen similar concerns in the community regarding transaction ID inconsistencies, but this specific case involves a clean auto-renewal flow without any complicating factors.

Biometric Authentication Behavior in IAP Sandbox Environment
Where the problem occurs: In-app purchase Non-ApplePay Non-local authentication login Environment where the problem occurs: Sandbox environment (Development environment, TestFlight environment) Problem handling process: Open page A in the app and purchase product B (auto-renewable subscription) on that page. User authentication is required to purchase product B. During the authentication process, the user needs to enter the Apple account and Apple account password. After completing the authentication, complete the purchase of product B. Problem in step 3: Why is FaceID or TouchID not used for authentication? Note: Face ID and Password -> iTunes Store and App Store -> Status is Enabled

Potential Issue Identified in Apple Documentation
While reviewing the Apple Documentation, I came across a potential issue in one of the examples that I believe is worth addressing. The example appears to compare strings instead of integers, which could lead to unexpected behavior in production environments. Specifically, in the line where originalMajorVersion (a string) is compared with newBusinessModelMajorVersion (also a string) using <: if originalMajorVersion < newBusinessModelMajorVersion This comparison performs a lexicographical check rather than evaluating the numerical values of the strings. As a result, strings like "10" would incorrectly be considered less than "2", which is not the desired behaviour when comparing version numbers. I have reported this via the Feedback assistant (FB16432337) but at the time of posting this there has been no reply at all (23 days) Supporting business model changes by using the app transaction do { // Get the appTransaction. let shared = try await AppTransaction.shared if case .verified(let appTransaction) = shared { // Hard-code the major version number in which the app's business model changed. let newBusinessModelMajorVersion = "2" // Get the major version number of the version the customer originally purchased. let versionComponents = appTransaction.originalAppVersion.split(separator: ".") let originalMajorVersion = versionComponents[0] if originalMajorVersion < newBusinessModelMajorVersion { // This customer purchased the app before the business model changed. // Deliver content that they're entitled to based on their app purchase. } else { // This customer purchased the app after the business model changed. } } } catch { // Handle errors. }

Regarding the pattern of multiple original transaction IDs being linked
In the app we're distributing, we've identified a user where the Get All Subscription Statuses API returns two original transaction IDs in the data response. This user has gone through cancellations and re-subscriptions since their initial purchase. Meanwhile, despite maintaining a continuous subscription, a notification suddenly arrives on the renewal date with original_transaction_id2. +---------------------------+---------------------------+---------------------+ | original_transaction_id | notification_type | subtype | +---------------------------+---------------------------+---------------------+ | original_transaction_id1 | SUBSCRIBED | INITIAL_BUY | ~ Repeated cancellations and re-subscriptions ~ | original_transaction_id1 | SUBSCRIBED | RESUBSCRIBE | | original_transaction_id2 | SUBSCRIBED | INITIAL_BUY | +---------------------------+---------------------------+---------------------+ Although it can be inferred from the interface definition of the API itself that multiple original transaction IDs may be returned, what causes multiple original transaction IDs to be returned? Furthermore, is it possible to reproduce the case where multiple original transaction IDs are returned in the sandbox environment provided by Apple? As for this app, it: Uses subscriptions through in-app purchases. Does not offer upgrades, downgrades, or crossgrades, having only one product. Has never undergone price increases or decreases. Is distributed exclusively in Japan.

The property Product.displayPrice does not display the correct price
Hi, I'm new to AppStore Connect, and I'm learning how subscriptions work. I'm finalizing my first app, but on my TF, I'm having some issues with the price: it's always displayed in US dollars on my paywall. When I tap "subscribe," the Apple sheet correctly offers the price in euros. I'm using Product.displayPrice to display the price in my paywall. The documentation did mention it is The localized string representation of the product price, suitable for display. So, is it normal in my case for the price in dollars to be displayed and not the price in euros like the Apple sheet? Thank you in advance for your help.

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。

How to test refunds of consumable purchases?
I have consumable IAPs in my app. Currently there is no way for me to test refunds for them as Xcode testing doesn't allow refunds option for my Purchases. According to this official documentation on Transaction.all , i should be getting my refunded consumables in Transaction's all property. But there is no way for me to know what kind of data is in the refunded transaction object. Will there be a 'revocation date' like in the case of non-consumables?

Receiving 404 Error for APNs Server Notifications When Validating signedPayload
Hi everyone, I'm experiencing an issue with APNs server notifications where I receive a 404 error when trying to validate the signedPayload from Apple's notification. Below is a sanitized version of my code: class ServerNotificationAppleController extends Controller { // URL for StoreKit keys (Sandbox environment) private $storeKitKeysUrl = 'https://api.storekit-sandbox.itunes.apple.com/inApps/v1/keys'; public function handleNotification(Request $request) { \Log::info($request); $signedPayload = $request->input('signedPayload'); if (!$signedPayload) { return response()->json(['error' => 'signedPayload not provided'], 400); } // Step 1: Create your JWT token (token creation logic can be in a separate service) $jwtToken = $this->generateAppleJWT(); // Step 2: Send a request to the StoreKit keys endpoint $response = Http::withHeaders([ 'Authorization' => 'Bearer ' . $jwtToken, ])->get($this->storeKitKeysUrl); Log::info('Apple Keys Status:', ['status' => $response->status()]); Log::info('Apple Keys Body:', ['body' => $response->body()]); if ($response->status() !== 200) { return response()->json(['error' => "Apple public keys couldn't be retrieved"], 401); } $keysData = $response->json(); // Step 3: Validate the signedPayload $validatedPayload = $this->validateSignedPayload($signedPayload, $keysData); if (!$validatedPayload) { return response()->json(['error' => 'Invalid signedPayload'], 400); } // Process the validated data as needed Log::info("Apple Purchase Data:", (array)$validatedPayload); return response()->json(['message' => 'Notification processed successfully'], 200); } private function generateAppleJWT() { // API key details (replace placeholders with actual values) $keyId = config('services.apple.key_id'); // e.g., <YOUR_KEY_ID> $issuerId = config('services.apple.issuer_id'); // e.g., <YOUR_ISSUER_ID> $privateKey = file_get_contents(storage_path(config('services.apple.private_key'))); // Set current UTC time and expiration time (20 minutes later) $nowUtc = Carbon::now('UTC'); $expirationUtc = $nowUtc->copy()->addMinutes(20); // Create the payload with UTC timestamps $payload = [ 'iss' => $issuerId, 'iat' => $nowUtc->timestamp, 'exp' => $expirationUtc->timestamp, 'aud' => 'appstoreconnect-v1', 'bid' => 'com.example.app', // Replace with your Bundle ID if necessary ]; // Generate the JWT token return JWT::encode($payload, $privateKey, 'ES256', $keyId); } private function validateSignedPayload($signedPayload, $keysData) { try { $jwkKeys = JWK::parseKeySet($keysData); return JWT::decode($signedPayload, $jwkKeys, ['RS256']); } catch (\Exception $e) { Log::error("Apple Purchase Validation Error: " . $e->getMessage()); return null; } } } I’m particularly puzzled by the fact that I receive a 404 error when trying to retrieve the public keys from the StoreKit keys endpoint. Has anyone encountered this issue or can provide insight into what might be causing the error? Any help or suggestions would be greatly appreciated. Thanks!
