Making numerical StoreKit transaction IDs in Xcode work with app store server notifications
Hi, I have a setup using App Store Server notifications, which has worked fine for a while now. However, I've never been able to successfully verify a purchase via Xcode, only via TestFlight. The reason for this is that the StoreKit transactions have numerical IDs (e.g. starting from 0, incrementing one-by-one), instead of UUIDs like in TestFlight/production. This means that often the backend will detect an existing transaction with the same ID and not complete the purchase. What are we meant to do here? If I send a custom ID to make it unique the backend won't accept this - I can ask them to change this for our dev environment but it's not ideal. What I'm after is a way to use UUIDs for transaction IDs when running via Xcode. Thanks

Payment screen not loading for app subscription
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

ExternalPurchase.presentNoticeSheet returns only cancelled in App Store version
Hello, Our app has been released in Korea with an external payment feature. The function that must display the required modal for external payments is as follows: let result = try await ExternalPurchase.presentNoticeSheet() guard result != .cancelled else { return } However, while testing in the development environment, the API returns a result of continuedWithExternalPurchaseToken(token: String), but in the version distributed through the App Store, it returns cancelled. We would like to know how we can receive the continuedWithExternalPurchaseToken result in the App Store version. Thank you for your guidance. If anyone here has experienced a similar issue or found a solution, I would greatly appreciate your insights as well.

[Bug/Doc Discrepancy] App Store Server API "price" field does not include quantity as documentation states
According to the App Store Server API documentation , https://developer.apple.com/documentation/appstoreserverapi/price the price field "shows the total amount of the transaction for the quantity the customer purchased." However, in actual transaction notifications and responses from App Store Server API, the price field appears to represent the unit price, not the total price. For consumable in-app purchases with quantity > 1, the price field equals the unit price of a single item. The total user payment is only correct after multiplying by the quantity. When quantity > 1, the actual amount paid by the user only matches price × quantity, which contradicts the documentation. Please confirm whether the price field is intended to be: The unit price of a single item (requiring multiplication by quantity), or The total price including all quantities (as currently documented). If the former is correct, please update the documentation to clarify that the value represents the unit price, not the total amount.

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

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...

StoreKit1 Usage error
I encountered the following issues while developing in-app purchases; please help me: When attempting to purchase a product that has already been purchased, SKPaymentQueue reports an error instead of a success message: <SKPaymentQueue: 0x134665380>: Payment completed with error: Error Domain=ASDServerErrorDomain Code=3532 "You’re currently subscribed to this." UserInfo={NSLocalizedFailureReason=You’re currently subscribed to this., client-environment-type=Sandbox, AMSServerErrorCode=3532, storefront-country-code=USA} After buying product A on one iPhone using a sandbox account, restoring purchases on another iPhone with the same sandbox account via paymentQueue.restoreCompletedTransactions(withApplicationUsername:) does not return the previously purchased product A data; it directly calls restoreCompletedTransactionsFinished.

Support Request: App Store Server Notification Inaccuracies
Unsure if this has been reported before, but I'm seeing a specific scenario where Apple is sending back faulty information in App Store Server Notifications. When users have payment failures that result in the membership expiring, and then reactivate later on with a different subscription, they are given a new originalTransactionId, yet we have three cases where we receive messages about the old originalTransactionId, indicating that after the user recovers their subscription, Apple is resurrecting the old subscription and treating it as if it is active BUT ultimately decides to deactivate it. Here is a sample screenshot of an impacted user. We only have three month and annual plans. Timeline: March 21st: This user signed up for a 3 Month Plan June 21st: This user fails to pay July 7th: After our 16 day grace period, this user loses access July 29th: This user sees they lost access and repurchase Augsut 19th: Their membership is deactivated (long before their 3 Month Subscription is up) For further verification I've also attached a record of all the payloads we've received from Apple for this user. Please let me know if you need any more details to fix this bug OR if it has already been fixed! Thank you. user_webhook_data_sanitized.csv

tvOS In-App Purchase – App Not Returning After Redirecting to Settings for Apple ID Verification
I'm encountering an issue with In-App Purchases on Apple TV (tvOS): When a user initiates an IAP for the first time, the system prompts them to sign in with their Apple ID, and the purchase proceeds normally. However, on subsequent purchase attempts, if the Apple ID session has expired or additional verification is required, the system redirects the user to the Settings app to sign in again. After the user signs in via Settings, the app does not automatically return to the foreground. The user must manually press the Menu button to come back. Is this is the normal behaviour of apple tv for InApp purchase? or did I need any code improvement to solve this? What I'm trying to achieve: I'd like the app to automatically return to the foreground once the user has completed the Apple ID login in Settings. Is this behavior supported on tvOS? If not, is there any known workaround or best practice to guide the user back to the app smoothly? Any advice or guidance from Apple or other developers would be greatly appreciated!

Subscription Purchase product issue
Hello Developer support, In one of our live application we have seen that users are purchasing weekly subscription and automatically they shifted to yearly product. Due to this we have received high revenue and also refunds afterwards. To prevent this we removed our yearly product from the sale. In App Store Connect we have seen activations for weekly product and convert to standard prices are yearly products. Also we have seen weird behavior of user getting trial for same product for three times. For developer support people I am sharing my app id - 1320373866 , and here is the video of our issue - https://drive.google.com/file/d/1DBHw8ivgql4eNoo8NC3xo5v4wgr8Oh7x/view?usp=sharing , Also attaching trial behavior screenshot.

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!
