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。

Hi, all!
I have an AppStore Server-side question. User sends up an AppReceipt that I am validating. What's the best way to tell the receipt belongs to said user? I want to make sure that the source of the AppReceipt was actually the original purchaser of the item. Is fetching Transaction + AppAccountToken the only way? AppAccountToken can only be utilized if the original purchase used it, and it is associated with the user's data. Is there another way?
アプリ内課金を実装しようとしていますが、サーバサイドのセキュリティに関してについて質問です。
StoreKit2を使えばアプリとApp Store Connect間のレシート検証は不要だが、
購入情報をサーバーで管理する場合は
アプリからサーバーに購入情報を渡す際にレシート検証する必要があると考えるがその認識であっているか教えていただきたいです。
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.

I have been struggling to test the IAP response but it is returning empty. I am now in the very beginning of one app, and I don't want to submit the contacts and banking and tax stuff that early. are these necessary for even testing IAP results locally? I think it does not make sense if I have to.
Hi everyone,
I’m struggling to get StoreKit 2 to fetch products in my SwiftUI app while using a sandbox user. I think I’ve followed all necessary setup steps in Xcode, App Store Connect, and my physical test device, but Product.products(for:) always returns an empty array. I’d appreciate any insights!
What I’ve Done
Local App Setup (Xcode 16.2)
Created a blank SwiftUI Xcode project.
Enabled In-App Purchase capability under Signing & Capabilities.
Implemented minimal StoreKit 2 code to fetch available products (see below).
Using the correct bundle identifier, which matches App Store Connect.
App Store Connect Configuration
Registered the app with the same bundle identifier.
Created an Auto-Renewable Subscription with:
Product ID: v1 (matches my code).
All fields filled (pricing, localization, etc.).
Status: Ready for Review.
Linked the subscription to the latest app version in App Store Connect.
Sandbox User & Testing Setup
Created a sandbox tester account.
Logged in with the sandbox user under Settings → Developer → Sandbox Apple ID. This was on my physical device (iOS 18.2).
Installed and ran the app directly from Xcode (⌘+R).
Issue: StoreKit Returns No Products
Product.products(for:) does not return any products.
There are no errors thrown, just an empty array.
I confirmed that StoreKit Configuration is set to None in Xcode.
No StoreKit-related logs appear in the Console.
Code Snippets
//StoreKitManager.swift
import StoreKit
import SwiftUI
@MainActor
class StoreKitManager: ObservableObject {
@Published var products: [Product] = []
@Published var errorMessage: String?
func fetchProducts() async {
do {
let productIDs: Set<String> = ["v1"] // Matches App Store Connect
let fetchedProducts = try await Product.products(for: productIDs)
print(fetchedProducts) // Debug output
DispatchQueue.main.async {
self.products = fetchedProducts
}
} catch {
DispatchQueue.main.async {
self.errorMessage = "Failed to fetch products: \(error.localizedDescription)"
}
}
}
}
//ContentView.swift
import SwiftUI
struct ContentView: View {
@StateObject private var storeKitManager = StoreKitManager()
var body: some View {
VStack {
if let errorMessage = storeKitManager.errorMessage {
Text(errorMessage).foregroundColor(.red)
} else if storeKitManager.products.isEmpty {
Text("No products available")
} else {
List(storeKitManager.products, id: \.id) { product in
VStack(alignment: .leading) {
Text(product.displayName).font(.headline)
Text(product.description).font(.subheadline)
Text("\(product.price.formatted(.currency(code: product.priceFormatStyle.currencyCode ?? "USD")))")
.bold()
}
}
}
Button("Fetch Products") {
Task {
await storeKitManager.fetchProducts()
}
}
}
.padding()
.onAppear {
Task {
await storeKitManager.fetchProducts()
}
}
}
}

}
Additional Information
iOS Version: 18.2
Xcode Version: 16.2
macOS Version: 15.3.1
Device: Physical iPhone (not simulator)
TestFlight Build: Not used (app is run directly from Xcode)
StoreKit Configuration: Set to None
Some of my users reported they can not completed the purchase .
According to the logs and screen captures . Their purchase progress's last status are "purchasing"
func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
....
....
case .purchasing:
// 处理正在购买的情况
//print("购买中");
AppDelegate.log.debug("paymentQueue purchasing");
LoadingAlert.shared.setText(text: "购买中".localized())
....
After this ,It neither entered any error branch nor prompted the user to confirm the purchase or enter a password, but simply stopped here. There are no other purchase-related logs, and the program is still running normally.
At the same time, other users are able to complete their purchases without any issues. However, there have been 4-5 users recently who reported problems with purchasing. What could be the possible reasons?
In my local environment, I repeated the test many times, including using sandbox users from different regions and real Apple IDs, and everything worked fine.

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.
I have an App Clip that uses SKOverlay.AppClipConfiguration to install the full app. Before I added a Live Activity call (Activity.request), the user could see “Install,” then “Open.” Now, once “Get” is tapped, the Clip immediately closes—no “Open” button appears. If I remove the Live Activity code, it works again.
I’ve confirmed that parent/child entitlements match, and tested via TestFlight. Is there a known issue or recommended workaround for combining SKOverlay + Live Activities in an App Clip so it doesn’t dismiss prematurely? Any insights are appreciated!
Note live activity is for App Clip only.
We are currently integrating In-App Purchases for our app and have configured App Store Server Notifications (v2) in the Sandbox environment.
During testing, we observed the following issue:
When a transaction is cancelled, declined, or pending (e.g., Ask to Buy flows or authorization pending),
No App Store Server Notification is sent to our webhook endpoint.
We only receive webhook events where the status is "purchased".
This becomes a critical problem for us because our backend must accurately track transaction states including failed and pending purchases, especially for wallet top-up use cases.
Additionally, we tried mocking failed transactions (via Xcode local environment and turning off In-App Purchases from Developer Settings) to simulate a technical failure scenario.
Even in these cases, no webhook notification was received when the purchase failed server-side.
Is it expected behavior in Sandbox that only successful transactions ("purchased") trigger webhooks?
Are failed or pending transactions suppressed in Sandbox intentionally?
Will webhook behavior be different in Production (i.e., will we receive webhook notifications for failures there)?
Is there any extra configuration or entitlement needed to fully test failure scenarios via webhooks in Sandbox?

App Store Server Notifications
I'm currently working on transitioning to StoreKit 2. In order to see if my users are legacy users who purchased the app before I implemented an in-app purchase, I am trying to use the original purchase date for the app. Unfortunately, it's returning 0 seconds since 1970.
func updateOriginalPurchaseStatus() async throws {
let transaction = try await checkVerified(AppTransaction.shared)
self.originalPurchaseVersion = transaction.originalAppVersion
self.originalPurchaseDate = transaction.originalPurchaseDate
}
This is from the transaction:
[3] = {
key = "originalPurchaseDate"
value = number (number = 0)
}
Currently trying to figure out when I actually purchased the app, but it might be as early as 2012. And I likely used a download code.
I try to access the AppDistributor.current (using try await) and the property never seem to return nor throw.
The code I'm using looks like this:
do {
print("accessing current")
let current = try await AppDistributor.current
print("current obtained")
switch(current) {
case .appStore:
return "AppStore"
default:
return "Unknown"
}
} catch {
return "Exception: \(error)"
}
But the log only shows the accessing current and never the current obtained. Trying to step in the property starts with some assembly, but at some point, the debugger just never returned. I join a full Swift file of a sample test I'm using:

We have a user that has an active subscription according to the appstore in our product but it is registering as expired. Hitting the subscribe button in the SwiftUI SK2 dialog does nothing, meaning, nothing happens.
Any ideas?

Hi everyone,
I've been going back and forth with Apple’s review team for over 10 days now, and I'm still unable to get my first In-App Purchase (IAP) working correctly.
Here's what’s happening:
✅ The IAP works perfectly when I build and run directly from Xcode.
❌ However, when I test the app via TestFlight, tapping the purchase buttons does nothing—the IAP sheet doesn't appear.
Key issue (I think):
I believe the IAP hasn't been submitted properly for review. On App Store Connect, I cannot select the IAP under the “In-App Purchases” section of the version submission page. It's grayed out or not listed at all. As a result, Apple keeps rejecting my binary due to the IAP not being included in the review.
What I’ve already done:
Created the IAP (non-consumable)
Set pricing and cleared all errors
Checked Bundle ID, Product ID, and entitlements
Added In-App Purchase capability to the app target
Uploaded the binary via Xcode
Waited multiple times for status updates
My questions:
What’s the correct process to link the IAP to a specific app version if it doesn't show up in the version page?
Could this be an issue with App Store Connect metadata or approval timing, or am I missing something in Xcode/build settings?
Is there any way to force re-sync the IAP so it appears when submitting the build?
Has anyone resolved a similar issue recently?
This process has been incredibly frustrating, and the feedback from the review team so far has been very vague. I would really appreciate any detailed insight or steps to ensure the IAP is submitted correctly and works on TestFlight.
Thank you in advance!

While testing an inapp purchase, if you purchase the same product twice from an account that does not have testflight permissions for the project and only has sandbox permissions, the second payment will receive the same transactionId as the first.
Why is that so? I know transactionID is unique.
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!
I set both production and sandbox App Store Notification server.
In sandbox, my server can receive all kinds of app store notification, including subscription and non-consumable in-app-purchase.
But in production, my server only receive subscription notification.
I can see some non-consumable in-app-purchase done in log, but the server didn't receive expected notification.
Anyone know why?
I really need the notification cause I need to know who made refund.
I had a two CS from customers that they couldn't buy a cookies(IAP). they got an alert "Purchases in this app are already purchased items."
I was wondering if anyone has any similar experiences.

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?

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.
