product not found !
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.

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

SKAdNetwork 3.0 postbacks are not being delivered.
Hi To test SkAdNetwork, I installed the profile from the documentation (https://developer.apple.com/documentation/storekit/testing-ad-attributions-with-a-downloaded-profile) on my ios device. and turned off and on Allow Apps to Request to Track to change the idfa value. In this state, I installed the app (bundle id: id436731843) using SKAdNetwork with the following values at April 8th AM 01 (UTC) SkAdnetwork version: 3.0 fidelity fidelity=0, nonce=b3346a51-f7b5-42a2-a508-775a62317c83, timestamp=1744076349671, signature=... fidelity=1, nonce=b3346a51-f7b5-42a2-a508-775a62317c83, timestamp=1744076349672, signature=... itunesitem=436731843 network=87u5trcl3r.skadnetwork sourceapp=1220307907 I was hoping to get a postback after , but after a day, the postback is still not delivered. Any idea why the postback is not delivered? Thank you

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?

Migrating a Paid App to In-App Subscriptions
Hello, I’m trying to change the business model of my app to in-app subscriptions. My goal is to ensure that previous users who paid for the app have access to all premium content seamlessly, without even noticing any changes. I’ve tried using RevenueCat for this, but I’m not entirely sure it’s working as expected. I would like to use RevenueCat to manage subscriptions, so I’m attempting a hybrid model. On the first launch of the updated app, the plan is to validate the app receipts, extract the originalAppVersion, and store it in a variable. If the original version is lower than the latest paid version, the isPremium variable is set to true, and this status propagates throughout the app. For users with versions equal to or higher than the latest paid version, RevenueCat will handle the subscription status—checking if a subscription is active and determining whether to display the paywall for premium features. In a sandbox environment, it seems to work fine, but I’ve often encountered situations where the receipt doesn’t exist. I haven’t found a way to test this behavior properly in production. For example, I uploaded the app to TestFlight, but it doesn’t validate the actual transaction for a previously purchased version of the app. Correct me if I’m wrong, but it seems TestFlight doesn’t confirm whether I installed or purchased a paid version of the app. I need to be 100% sure that users who previously paid for the app won’t face any issues with this migration. Is there any method to verify this behavior in a production-like scenario that I might not be aware of? I’m sharing the code here to see if you can confirm that it will work as intended or suggest any necessary adjustments. func fetchAppReceipt(completion: @escaping (Bool) -> Void) { // Check if the receipt URL exists guard let receiptURL = Bundle.main.appStoreReceiptURL else { print("Receipt URL not found.") requestReceiptRefresh(completion: completion) return } // Check if the receipt file exists at the given path if !FileManager.default.fileExists(atPath: receiptURL.path) { print("The receipt does not exist at the specified location. Attempting to fetch a new receipt...") requestReceiptRefresh(completion: completion) return } do { // Read the receipt data from the file let receiptData = try Data(contentsOf: receiptURL) let receiptString = receiptData.base64EncodedString() print("Receipt found and encoded in base64: \(receiptString.prefix(50))...") completion(true) } catch { // Handle errors while reading the receipt print("Error reading the receipt: \(error.localizedDescription). Attempting to fetch a new receipt...") requestReceiptRefresh(completion: completion) } } func validateAppReceipt(completion: @escaping (Bool) -> Void) { print("Starting receipt validation...") guard let receiptURL = Bundle.main.appStoreReceiptURL else { print("Receipt not found on the device.") requestReceiptRefresh(completion: completion) completion(false) return } print("Receipt found at URL: \(receiptURL.absoluteString)") do { let receiptData = try Data(contentsOf: receiptURL, options: .alwaysMapped) print(receiptData) let receiptString = receiptData.base64EncodedString(options: []) print("Receipt encoded in base64: \(receiptString.prefix(50))...") let request = [ "receipt-data": receiptString, "password": "c8bc9070bf174a8a8df108ef6b8d2ae3" // Shared Secret ] print("Request prepared for Apple's validation server.") guard let url = URL(string: "https://buy.itunes.apple.com/verifyReceipt") else { print("Error: Invalid URL for Apple's validation server.") completion(false) return } print("Validation URL: \(url.absoluteString)") var urlRequest = URLRequest(url: url) urlRequest.httpMethod = "POST" urlRequest.httpBody = try? JSONSerialization.data(withJSONObject: request) URLSession.shared.dataTask(with: urlRequest) { data, response, error in if let error = error { print("Error sending the request: \(error.localizedDescription)") completion(false) return } guard let data = data else { print("No response received from Apple's server.") completion(false) return } print("Response received from Apple's server.") do { if let json = try JSONSerialization.jsonObject(with: data) as? [String: Any] { print("Response JSON: \(json)") // Verify original_application_version if let receipt = json["receipt"] as? [String: Any], let appVersion = receipt["original_application_version"] as? String { print("Original application version found: \(appVersion)") // Save the version in @AppStorage savedOriginalVersion = appVersion print("Original version saved in AppStorage: \(appVersion)") if let appVersionNumber = Double(appVersion), appVersionNumber < 1.62 { print("Original version is less than 1.62. User considered premium.") isFirstLaunch = true completion(true) } else { print("Original version is not less than 1.62. User is not premium.") completion(false) } } else { print("Could not find the original application version in the receipt.") completion(false) } } else { print("Error parsing the response JSON.") completion(false) } } catch { print("Error processing the JSON response: \(error.localizedDescription)") completion(false) } }.resume() } catch { print("Error reading the receipt: \(error.localizedDescription)") requestReceiptRefresh(completion: completion) completion(false) } } Some of these functions might seem redundant, but they are intended to double-check and ensure that the user is not a previous user. Is there any way to be certain that this will work when the app is downloaded from the App Store? Thanks in advance!

How to check if user still have valid subscription?
Is there an API Endpoint that I can call to check if user still have valid subscription? I want to be sure that his subscription renewal was succesful (ie: I dont want to give him another month/year/.. if his latest renewal wasnt successful) Would GET https://api.storekit.itunes.apple.com/inApps/v1/transactions/{transactionId} be the correct API endpoint to call? But I wonder, after subscription auto-renews, do we still use the same transactionId to check whether his subs is still valid?

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?

Purchase Confirmation Letter
Hi all, I've received emails from other apps after making a purchase, with content like: You have purchased {App Name} on {Date & Time} and acknowledged that if you download or use this in-App Purchase within fourteen days of buying it, you will no longer be eligible to cancel this purchase. Do anyone know under what circumstances Apple sends a Purchase Confirmation Letter to the user's email after they purchase our digital products via IAP? Is this something developers can control? Additionally, I've seen pop-up reminders before making a payment in apps, with content similar to the above message. Are these reminders provided by Apple, or can developers create their own guidance to help users avoid accidental purchases? Kindly, Vanto

App Store Server Notifications Update
Hello Apple Support Team, We're a developer team that has created an app with subscription-based features, and we've been using App Store Server Notifications to receive updates about user subscription status changes. I'm reaching out to inquire about potential modifications to the App Store Server Notifications approach that might have improved notification delivery times for my app. So on our appstore app, when a user purchases a subscription, the apple server notifications reach our server and send us the complete detail of that user’s purchase for eg he upgraded or downgraded etc. And then based on the data we receive from app store server notifications, we save it in our database, along with updating the users subscription table in the database. Previously, we experienced delays in receiving the real time notifications from apple on our server, sometimes taking a few minutes, while other times they would arrive immediately. And because of this issue, the users faced delay in seeing their subscription updates, as our db was updated only after the app store server notification reached our server. However, recently, we've noticed a significant improvement, and notifications are now being delivered still in real-time, but without any noticeable delays. I'm wondering if Apple has made any changes to the App Store Server Notifications system that might have resolved the delay issue. Could you please confirm if any modifications were made in 2025, specifically from January onwards, that might have improved notification delivery times? Additionally, I'd like to know if these changes apply to both sandbox testing and production environments. If possible, could you please provide more information about the changes or direct me to a resource that might explain the updates? I'd appreciate your assistance in confirming this information, and I'm looking forward to hearing back from you.

AppStore response times for the store test environment to make purchases is very long.
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.

All transaction in my current entitlement returns as .unverified
Im building a small iphone app with StoreKit and currently testing it in testflight right on my mac, not on iphone. StoreKit part almost exactly copied from SKDemo from one of the Apple's WWDC. For some users and for myself Transaction.currentEntitlements always returns .unverified results. I double-checked Apple Connect settings, i checked my internet connection and everything is fine. Is there some pitfalls for testflight on mac? How can I find out what is causing this problem?

appTransactionID behavior on logout
The appTransactionID was recently introduced and is documented here: https://developer.apple.com/documentation/storekit/apptransaction/apptransactionid From the documentation: "The App Store generates a single, globally unique appTransactionID for each Apple Account that downloads your app and for each family group member for apps that support Family Sharing." This seems like a really useful identifier, so I was wondering about some edge cases of when using it: What happens if a user logs out of his AppStore account and keeps using the app? Is it available when the app is installed from Xcode? is it possible to set it to some value using StoreKit testing? Thanks

Subscription IAP - SubscriptionStoreView results and errors - more info needed. FB19376771
FB19376771 Transactions monitoring. If I only have subscriptions, do I really need to "bother" with any sort of monitorTransactions() or just rely on subscription status (subscribed, revoked, cancelled ...) ? This is in line with Apple SKDemo and recommendation: // Only handle consumables and non consumables here. Check the subscription status each time // before unlocking a premium subscription feature. switch transaction.productType { ref: [https://developer.apple.com/documentation/storekit/implementing-a-store-in-your-app-using-the-storekit-api) The "Only handle consumables and non consumables here" recommendation by Apple in ref to the process transaction code above is nuanced and confusing if we know what was with other external experts recommendation saying when using only SK2 Views : "This is where most developers trip up in trying to get an experience that App Review is happy" ... continuing : "Be careful: that Purchase View code alone isn’t enough, because one of the possible completion status is .pending: the purchase is in the process of happening but hasn’t completed yet, so you still need to watch the transaction queue manually to be absolutely sure of handling the process completely." Does this holds true for the new SubscriptionStoreView ? We are not sure with quite obscure Apple documentation what SubscriptionStoreView handles, other than purchase (and now subscribe) function, and we do not know what diverse type of error handling messages it can return. Moreover, Apple documents: "Only handle consumables and non consumables here" ? @Apple can you please share more insights on Purchase button on SubscriptionStoreView e.g A) does it close ( finish). the purchase transaction ? B) What error results can it return ? C) What .onInAppPurchaseCompletion can handle as result ?

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.
