IAP Product Fetch Returns Empty Array in React Native iOS App
We're experiencing an issue with in-app purchases in our React Native iOS app where RNIap.getProducts() is consistently returning an empty array, preventing users from making purchases. Technical Details: Using react-native-iap library Product ID: '[REDACTED]' Platform: iOS Product Type: Consumable (one-time payment, NOT subscription) Error in logs: "No products returned from App Store. Check App Store Connect." Debugging shows: Products Fetched: [] Steps to Reproduce: Open app and navigate to the quiz feature Attempt to purchase additional quiz attempts Modal opens but fails to load product information What We've Confirmed: IAP Connection initializes successfully No error is thrown during product fetch, just an empty array returned App is configured with correct Bundle ID Using Apple Sandbox test account We are implementing consumable purchases (one-time payments) Potential Issues to Investigate: Product configuration in App Store Connect Ensure product is set as "Consumable" type in App Store Connect Sandbox tester account permissions/activation Bundle ID matching between app and App Store Connect Product ID case sensitivity or typos

“Billing problem” after free trial subscription expiry in sandbox environment
Yesterday I noticed that if I purchase a free trial subscription in my app using a sandbox account, when the subscription expires I see a “Billing Problem” message every time I open the app. ”allow purchases & renewals“ setting is ON so this shouldn’t happen. has anyone else seen this or knows how to resolve? observed on iOS 18.3.2 & 16.7.10 thanks

Billing Problem while subscription renewal.
Hello, I'm currently experiencing issues with IAP subscription setup. The following error appears: "Billing Problem, There was a problem with your subscription renewal. To resolve, turn on Allow Purchases & Renewals, or leave off to test failed in-app purchase attempts and subscription renewals." I'm testing with a sandbox account, and automatic subscription renewal is turned on in the sandbox settings. A notification screen appears at the OS level, and consequently, a DID_FAIL_TO_RENEW error occurs on our payment server. I cannot determine the cause at all, so I would appreciate your assistance in checking this issue.

Mac OS 15.4 breaks receipt Validation
I'm using Swift to verify receipts in myObjective C Mac Application using the following code: @objc class MyAppTransaction: NSObject{ @objc class func checkReceipt() async -> String { do { let verificationResult = try await AppTransaction.shared switch verificationResult { case .verified(_): return "VERIFIED" case .unverified(_, _): return "NO RECEIPT" } } catch { return "ERROR" //(StoreKit.StoreKitError) unknown } } } Starting today with my upgrade to Sequoia 15.4 and XCode 16.3 receipt validation is broken. The function is going to the catch and returning "ERROR" I can't set a break point in the do {} but if I set one at the return "ERROR", in the debugger error = (StoreKit.StoreKitError) unknown. the Compiler logs an error:Failed to parse AppTransaction: missingValue(for: [StoreKit.AppTransaction.Key.appTransactionID], expected: StoreKit.BackingValue). Reading the developer documentation I can't find anything about these struct members. I tried to use refresh() to get a receipt like I used to with exit(173) but the compiler says refresh () not found. This is extremely troubling because I can't debug my receipt validation code and I don't know if this will happen to my users. Do I just have to trust Apple that my users will have an application with a receipt attached? What can I do?

The currency information obtained from [priceLocale] differs between the TestFlight version and the official release version.
When creating a subscription charging system for an iOS app, I am trying to change the display to yen, dollars, or euros depending on the user's country. I am using [priceLocale] of [SKProduct] in [StoreKit] to obtain currency information linked to the Apple account from the App Store and change the display. The smartphone I am testing on uses an Apple account created in Japan, and the nationality of the App Store is also set to Japan, so I expect the display to be in yen. As a result, the TestFligh version displayed dollars, but the official release version displayed yen. Why doesn't the TestFligh version display yen?

Unknown Error Occurring During Sandbox Purchase Testing
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?

Dev Defined IAP Transaction Metadata
I have an app that works by being able to map IAP transactions to a predefined user ID. This means when I consume events from Apple's App Store Server Notifications endpoints I have to do a reverse lookup in order to assign permissions within my app. Workflow: User purchases subscription within the app via IAP. The app persists the subscriptionID from the Apple IAP library in my cloud database (Firestore). Cloud function receives the event from App Store Server Notifications endpoint and looks up the user ID containing the persisted transactionID (with retries to avoid race condition). Question: This workflow works but it seems an improvement would be to allow dev's to append metadata, like the user ID, to the transaction submitted to IAP that we can access within the signedTransactionInfo of the event from the App Store Server Notifications endpoint in order to facilitate a direct lookup of the user document needing it's permissions updated. This would greatly simplify workflows that use non-Apple systems as a source of truth for app permissions. Does this actually exist already? If not, is there a feature request platform?

InApp purchases ok and ko at the same time (?!)
I'm working on an app the has implemented inapp purchases. They have been working so far, and they keep working currently. But just a couple of days ago, a specific user sent us a support ticket stating that when he purchases and item the bank charges it for the purchase, but within the app, the purchase fails and he doesn't receive the item. He sent us screenshots showing: The iOS native modal when a purchases has been finished correctly ("You're all set - Your purchase was successful "). Right after that modal, the app shows an internal modal showing "The purchase failed, please, try again later". Checking the app logs, that failure modal was triggered by "The operation couldn’t be completed. (StoreKit.StoreKitError error 1.)". Reading docs about this error leads me to think about device or user restrictions (parental controls, usage limits, etc...). It seems that in theses cases the bank charge could be issued but refunded later once Apple ultimately declines the purchase. However the user says that he doesn't have any kind of restriction. The only related thing is a "this device is also restricted by a profile" message, but everyone seems to have this message. What could it be causing this issue? In what scenariowould the app show a native OK modal but a storekit error 1? I'm pretty sure the app is well configured because I keep receiving purchases of all kind, from different users with any problem.

Purchase information for users with multiple original transaction IDs
We are currently performing maintenance and operation on our app. I would like to ask a question about Apple's purchase processing. When retrieving purchase information for a user who has multiple original transaction IDs, such as original transaction ID AAA and original transaction ID BBB, if "Get All Subscription Statues" is executed with BBB as an argument, is it possible that purchase information for original transaction ID "AAA" will be retrieved? If this kind of issue does occur, please share the conditions under which it occurs.

How to Verify the Authenticity of an In-App Purchase Receipt from Apple Pay?
I am an app developer, and I have implemented in-app purchases in my application. When a user completes a purchase, Apple displays a success popup. After the user taps "OK", I send the receiptData to my server to add points to their account. However, I have encountered cases where users either exit the app before tapping "OK" or experience network issues, preventing the receipt from being sent to my server. As a result, they do not receive their points. Later, some users send me a receipt from Apple Pay, claiming that the payment was successful. These receipts include details such as the orderId, email, and other transaction information. However, I am not certain whether the user actually completed the payment but encountered an issue, or if they are providing a fraudulent receipt. My question: How can I verify the authenticity of these receipts? Is there an official way to check if a given Apple Pay invoice corresponds to a real in-app purchase in my app? Any guidance or best practices would be greatly appreciated!

Storekit, how to change and retrieve current user storefront
I've been struggling to work with the Storekit framework and specifically to find the current Storefront used by the user of the app. Context : My app needs to behave differently depending on the country of the user. For me relying on Locale.current.region?.identifier does not seem very reliable, the user can change it really easily. I'm trying to use the Storekit framework like so : if let storefront = await StoreKit.Storefront.current{ return storefront.countryCode } As per Apple's Storekit documentation : Use current to determine a customer's current storefront region and offer in-app products suitable for that region. You maintain your own list of product identifiers and the storefronts in which you make them available. But I just can't find out what I need to change in my current configuration to get another country. The code keeps returning my original storefront (which is France) I've tried login in with a sandbox user defined on another country. Changed all settings on my device to another country. Changed my Apple's account region as described here. Also tried to logout from everything. The only thing that works is setting a local .storekit file as described here and changing the default storefront. Is Xcode overriding the default storefront when building on debug or TestFlight? does anyone know how can I test different storefronts with sandbox users without the local storekit file ? Thank you in advance.

original_transaction_id associated to web_order_line_item_id of auto-renewable subscription changed
Our app offers auto-renewable subscriptions using StoreKit Original API for In-App Purchase and App Store Server Notifications V1. Starting around 2025-03-15, we found some cases where original_transaction_id which was associated to web_order_line_item_id of already purchased subscription had changed in the receipt information of verifyReceipt response or App Store Server Notifications V1. The detailed steps are: Around February 2025, re-purchase from the app the same subscription product which was canceled and expired some time ago, using StoreKit Original API for In-App Purchase Receive the following 2 notifications from App Store Server Notifications V1 almost at the same time INITIAL_BUY DID_CHANGE_RENEWAL_STATUS In both notifications, latest_receipt_info contains the receipt for the re-purchased subscription period with new original_transaction_id and web_order_line_item_id pending_renewal_info contains both new original_transaction_id and original one which was generated at first purchase, and original one has "is_in_billing_retry_period": "1" Starting around 2025-03-15, the following happens When we receive another "DID_CHANGE_RENEWAL_STATUS" notification from App Store Server Notifications V1, original_transaction_id which is associated to web_order_line_item_id of the re-purchased subscription period has changed back to the original one (the one which was generated at first purchase) in latest_receipt_info. When we call verifyReceipt with the receipt obtained from appStoreReceiptURL, the response does not seem to contain new original_transaction_id which was generated at re-purchase We have some questions regarding this original_transaction_id behavior. When a user re-purchase the same subscription product which was canceled and expired some time ago, it seems that new original_transaction_id is generated. Is this an expected behavior? If yes, it seems that, at some point, original_transaction_id which is associated to web_order_line_item_id of the re-purchased subscription changed back to the original original_transaction_id which had been generated at first purchase. Is this an expected behavior? What triggers the original_transaction_id change to the original one? Is it related to some user actions or subscription status change?

AppTransaction.shared doesn’t return originalAppVersion for users who installed the app in 2017
Hi, I'm using the AppTransaction.shared API to retrieve the originalAppVersion, but I'm encountering issues for users who originally installed the app in 2017. Specifically, the property doesn't seem to return the expected value (or returns nil) for these older accounts. I have verified this issue using a real App Store purchase from 2017. Steps to Reproduce: Use a test account that originally downloaded the app in 2017. Call: let shared = try await AppTransaction.shared print(shared.originalAppVersion) Observe that originalAppVersion is missing or not returned correctly. Any insights on whether this is expected behavior for very old App Store purchases, or if there is a workaround to reliably detect the original app version? Thanks in advance!

Sandbox Testing Issue: 'Submit for Review' Button Missing for Subscription IAPSubmit
Hello Developers! I am trying to run a test In-App Purchase (IAP) for a renewable subscription product in the sandbox environment. I have set up everything required for sandbox testing, but it’s unclear whether the subscription product needs to be pre-approved by Apple for testing. If approval is required, I have already added the necessary metadata, but the status still shows "Ready for Submit." Additionally, when I save the page, a "Submit for Review" button briefly appears for a fraction of a second on the subscription page before disappearing. Is this button missing, or is there a known issue with this process? This is my first time running this test, and I would appreciate any pointers or suggestions. Thanks!

iOS in-app purchasing in Unity app
Hi everyone, I am working on a Unity iOS app. I am adding in-app purchasing in my app. I have added Unity IAP to the Unity project, as well as the code for initialising and purchasing a subscription with the product ID. I have also added my certificates and provisioning profile in Xcode with in-app purchasing capabilities. Also, I have set up an App Store Connect page with a non-renewing subscription with a unique product ID and all required information. The subscription status is ready to submit. I have added a sandbox tester account in it. In unity editor, it is working fine with fake purchase receipt. While testing in an iOS device, apple ID is logged out. But there is an error occurs everytime : IAP not initialized. Also I have uploaded a newer version of app on app store connect, it is in waiting for review status. Is there any step or something I am missing that it is not working in iOS device? Please help
