最近我们有个应用要对接App 内购买项目，有什么好的资料或者demo提供一下吗？

We are using consumable in-app purchases. Starting from May 27th, we began receiving refund callbacks with the notificationType set to ONE_TIME_CHARGE immediately after users successfully completed a payment. { "notificationType": "ONE_TIME_CHARGE", "signedPayload": "..." } During this period, we did not make any changes to our App release or server-side purchase handling logic. Could this issue result in actual refunds being processed? What steps should we take to resolve this issue? We also noticed in your changelog that a new notification type ONE_TIME_CHARGE has been introduced. Can we safely ignore callbacks with the ONE_TIME_CHARGE notification type without affecting refund processing or user experience?

I am currently using the App Store Server API Get All Subscription Statuses in the app I am in charge of. Please let me confirm the following regarding Get All Subscription Statuses. ■Prerequisites The language used is Objective-c, and I am using both XCode 15 and 16. I also have an App Store Connect account. ■Questions Is it possible to set and test each status of the App Store Server API Get All Subscription Statuses with TestFlight?

users download app with Streamlined Purchasing ,but the logic of checking subscription doesn't work. there the code: func checkSubscriptionStatus() async { for await entitlement in Transaction.currentEntitlements { guard case .verified(let transaction) = entitlement else { continue } if transaction.productID == monthlyProductID || transaction.productID == yearlyProductID { if transaction.revocationDate == nil && !transaction.isUpgraded { let activeSubscribed = transaction.expirationDate ?? .distantFuture > .now if activeSubscribed { hasActiveSubscription = activeSubscribed // other operation } } } } }

I am finding that the verifyReceipt endpoint used to verify a receipt is failing on occassion starting around October 27, 2015. I realize this API is deprecated. I am using cURL to call verifyReceipt. The specific errors are 52 - Empty reply from server and 56 - Connection closed abruptly. This indicates an issue with Apple's server as I understand it. Is anyone else experiencing this as well?

Is the following subscription cancellation flow possible for an iOS in-app subscription? (Note: This is during the feature planning stage, not actual app deployment.) Planned user flow: User taps the “Cancel Subscription” button Display a “Wait a moment!” screen showing how much the user has enjoyed BFLIX content (to encourage retention) User taps “Proceed to Cancel” Collect cancellation reason from the user Redirect the user to the Apple subscription management page to complete cancellation Can this flow be implemented under Apple’s current in-app purchase and App Store Review guidelines?

A customer of mine signed up for a free trial. I got a apple server notification with notification type DID_RENEW. What does that mean? Does that mean that they will be charged the subscription price now?

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?

Hey guys, somehow I used my real ID(not sandbox test ID) to purchase a non-consumable item in the TestFlight package, no actual payment was made, but this payment record cannot be erased. Even though I know the transaction ID, I cannot initiate a refund like using refundRequestSheet(). Does anyone know how to deal with this, or there is no way to solve it?

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?

For testing purposes, I log out of media and purchases to use sandbox ID's to test in app purchases. Once I log out of media and purchases in device settings, in app purchases is still using my real apple ID, I'm not being prompted anymore to log into a sandbox ID for purchases.

Hello, I’m facing an issue with auto-renewable subscriptions in my React Native iOS app using react-native-iap. Before App Store approval, everything worked perfectly — I could test in-app purchases and subscriptions locally on my iPhone through Xcode using a development build and sandbox tester. After the app was approved and released on the App Store, I needed to make some updates. Now, when I build and run the same project again through Xcode (Debug, development-signed) on my iPhone, the subscriptions no longer load. The same product IDs are approved and live in App Store Connect. The live version on the App Store works fine (subscriptions load and process successfully). But on the local Xcode build, getSubscriptions() returns invalid product identifiers or an empty list. No changes were made to the bundle ID or product IDs The build is signed with an Apple Development certificate and uses the same team and bundle identifier as the published app. “In-App Purchase” capability is enabled. I’ve also tried deleting the app, rebooting the device, and re-logging into a sandbox tester account, but the issue persists. It looks like the sandbox environment no longer works for the app after its first App Store release. Has anyone experienced this issue where the same approved app’s IAPs work in production but fail to load in sandbox/dev builds through Xcode after release? Any guidance on re-enabling sandbox testing for updates would be greatly appreciated. Environment: Xcode 26.0.1 React Native with react-native-iap Auto-renewable subscriptions (3 SKUs) Thank you!

Starting around October 12, 2025 at 19:51 UTC, we're seeing intermittent failures when verifying StoreKit transaction JWTs. The issue appears to be related to certificate expiration in the x5c chain in the JWT tokens provided by Apple. What We're Seeing Some JWTs are being signed with different certificates. Some work, some fail certificate validation. Old Certificate (Expired - causing failures): Subject: Prod ECC Mac App Store and iTunes Store Receipt Signing Issuer: Apple Worldwide Developer Relations Certification Authority (G6) Serial: 166451396673336810269824643773700992094 Valid From: 2023-09-12 19:51:53 UTC Valid To: 2025-10-11 19:51:52 UTC ❌ EXPIRED New Certificate (Valid - working): Subject: Prod ECC Mac App Store and iTunes Store Receipt Signing Issuer: Apple Worldwide Developer Relations Certification Authority (G6) Serial: 95385247725814954943813376527885434295 Valid From: 2025-09-19 19:44:51 UTC Valid To: 2027-10-13 17:47:23 UTC ✓ VALID Current Status Most JWTs use the new valid certificate. Some JWTs still use the expired certificate. This appears inconsistent/random. I don't know if it's an issue with some of Apple's servers, or an issue with StoreKit on-device cache, but seems to me like a bug on Apple's side either way. Are we missing something? Is this a known issue? Any guidance or timeline from Apple would be greatly appreciated, as this is blocking legitimate paying users.

We've been approved for the Advanced Commerce API. After receiving the approval, we completed the initial setup requirements (submitted a generic product ID and shared our subscriptions page deep link). When testing the Migrate Subscription to Advanced Commerce endpoint in the sandbox, we receive a 5000000 error. What could be the reason/s for it? There is no information, and the API call we make includes all required parameters. Could it be related to the fact that our new generic product ID status is "Missing Metadata"? Is there a way to understand what the issue is on Apple's side?

Hi, I have developed an app which has two in-app purchase subscriptions. During the test, the app can successfully get the status of the subscriptions. After it's released, I downloaded it from app store and subscribed it with my apple account. I found that in most cases, the app can identify that I have subscribed it and I can use its all functions. But yesterday, when I launched it again, it showed the warning that I haven't subscribed it. I checked my subscription in my account and the subscription status hasn't been changed, that is, I have subscribed it. And after one hour, I launched it again. This time the app identified that I have subscribed it. Why? The following is the code about listening to the subscription status. Is there any wrong about it? HomeView() .onAppear(){ Task { await getSubscriptionStatus() } } func getSubscriptionStatus() async { var storeProducts = [Product]() do { let productIds = ["6740017137","6740017138"] storeProducts = try await Product.products(for: productIds) } catch { print("Failed product request: \(error)") } guard let subscription1 = storeProducts.first?.subscription else { // Not a subscription return } do { let statuses = try await subscription1.status for status in statuses { let info = try checkVerified(status.renewalInfo) switch status.state { case .subscribed: if info.willAutoRenew { purchaseStatus1 = true debugPrint("getSubscriptionStatus user subscription is active.") } else { purchaseStatus1 = false debugPrint("getSubscriptionStatus user subscription is expiring.") } case .inBillingRetryPeriod: debugPrint("getSubscriptionStatus user subscription is in billing retry period.") purchaseStatus1 = false case .inGracePeriod: debugPrint("getSubscriptionStatus user subscription is in grace period.") purchaseStatus1 = false case .expired: debugPrint("getSubscriptionStatus user subscription is expired.") purchaseStatus1 = false case .revoked: debugPrint("getSubscriptionStatus user subscription was revoked.") purchaseStatus1 = false default: fatalError("getSubscriptionStatus WARNING STATE NOT CONSIDERED.") } } } catch { // do nothing } guard let subscription2 = storeProducts.last?.subscription else { // Not a subscription return } do { let statuses = try await subscription2.status for status in statuses { let info = try checkVerified(status.renewalInfo) switch status.state { case .subscribed: if info.willAutoRenew { purchaseStatus2 = true debugPrint("getSubscriptionStatus user subscription is active.") } else { purchaseStatus2 = false debugPrint("getSubscriptionStatus user subscription is expiring.") } case .inBillingRetryPeriod: debugPrint("getSubscriptionStatus user subscription is in billing retry period.") purchaseStatus2 = false case .inGracePeriod: debugPrint("getSubscriptionStatus user subscription is in grace period.") purchaseStatus2 = false case .expired: debugPrint("getSubscriptionStatus user subscription is expired.") purchaseStatus2 = false case .revoked: debugPrint("getSubscriptionStatus user subscription was revoked.") purchaseStatus2 = false default: fatalError("getSubscriptionStatus WARNING STATE NOT CONSIDERED.") } } } catch { // do nothing } if purchaseStatus1 == true || purchaseStatus2 == true { purchaseStatus = true } else if purchaseStatus1 == false && purchaseStatus2 == false { purchaseStatus = false } return }

I’m reaching out regarding our existing in-app subscription implementation that currently uses App Store Server Notifications version 1 (v1). Our live application has a significant number of active recurring subscriptions that are being managed through the v1 webhook integration. We have now developed a revamped version of our application, which uses the same Apple Developer Account and App Store Connect setup, but in this new app version, we’ve implemented App Store Server Notifications version 2 (v2). Before moving forward with the migration, I would like to clarify the following points to ensure a smooth transition and avoid any disruptions to ongoing subscriptions: Backward Compatibility: Will existing active subscriptions (originally created and managed via v1 notifications) continue to work seamlessly once we switch to v2, or do we need to maintain both v1 and v2 endpoints during the transition? Notification Delivery: If both webhook versions are configured simultaneously, will Apple send notifications to both endpoints, or only the one currently configured in App Store Connect? Migration Strategy: What is Apple’s recommended best practice for migrating from v1 to v2 in a scenario where the live app still has active subscriptions tied to the v1 webhook? Potential Risks or Considerations: Are there any known limitations, delays, or issues that we should prepare for during this migration (for example, differences in payload structure or event types between v1 and v2 that could affect subscription lifecycle management)? I would greatly appreciate your guidance or documentation links that outline the correct migration steps and recommended approach for ensuring continuity of service for all existing subscribers.

Problem: I'm implementing StoreKit 2 in my SwiftUI app. Products load successfully when I rebuild in Xcode, but on a fresh install, Product.products(for:) returns an empty array. The paywall shows "Unable to load pricing." Setup: Using StoreKit Configuration File ( .storekit ) for testing Product IDs match exactly between config and code: com..premium.lifetime (non-consumable) com..premium.monthly (auto-renewable subscription) com.****.premium.yearly (auto-renewable subscription) StoreKitManager is a @MainActor singleton with @Published properties What I've Tried: Initial delay before loading - Added 1-second delay in init before calling loadProducts() Product ID verification - Confirmed IDs match exactly between StoreKitConfig.storekit and code Retry logic with exponential backoff - Implemented 3 retry attempts with 0.5s/1s/1.5s delays Multiple calls to updatePurchasedProducts() - Called twice after initial load Verified StoreKit configuration - File is properly added to project, has valid product definitions Code Structure: swift @MainActor final class StoreKitManager: ObservableObject { static let shared = StoreKitManager() @Published private(set) var products: [Product] = [] private init() { updateListenerTask = listenForTransactions() Task { try? await Task.sleep(nanoseconds: 1_000_000_000) await loadProducts() // Returns empty on fresh install await updatePurchasedProducts() } } } Observations: ✅ Works perfectly after Xcode rebuild ❌ Fails on fresh app install (simulator & device) ❌ Product.products(for:) returns empty array (no error thrown) ✅ StoreKit configuration file is valid and properly configured Question: Why does StoreKit need a rebuild to recognize products? Is there a proper initialization sequence I'm missing for fresh installs? Environment: Xcode [Version 26.0 beta 7] iOS [IOS +17.0] Testing with StoreKit Configuration File

Hello, I added new In-App Purchase into my app, it was approved on 2nd of Oct but now 7th of Oct I still cannot see it in the list of products coming from Store. I already have 2 subscriptions and 1 In-App purchase in my app, but the new In-App purchase is still not coming from the store in available products. What could cause this?

I'm encountering an issue with the App Store Server API where the appAccountToken is not preserved when users migrate their Apple ID email addresses. I've submitted Feedback Assistant ticket FB18709241 but wanted to check if anyone else has experienced this and get community input on best practices. The Issue When a user migrates their Apple ID from one email to another (e.g., from olduser@example.com to newuser@icloud.com), the App Store creates a new subscription transaction with a different originalTransactionId, but the appAccountToken is not carried forward from the original transaction. What I'm Seeing note: these values are fake When querying /inApps/v1/subscriptions/{originalTransactionId} with the either post-migration transaction ID or the pre-migration transaction ID, the API returns both transactions: Pre-migration transaction (status: 2 - inactive): originalTransactionId: "12345678910111" Contains: "appAccountToken": "abc123-def456-ghi789" Post-migration transaction (status: 1 - active): originalTransactionId: "67891011121314" Missing: appAccountToken entirely The Problem The appAccountToken is our only way to link App Store subscriptions to user accounts. Without it on the new transaction: Users lose access to premium features despite having valid subscriptions Server-side renewal notifications can't be matched to user accounts Manual support intervention is required for each affected user Questions for the Community Has anyone else encountered this issue with Apple ID migrations? What's the recommended approach for handling this scenario? Is there an alternative mechanism to maintain the subscription-to-user linkage across migrations? Questions for Apple Engineers Is this the expected behavior, or should the appAccountToken be preserved? Are there any planned improvements to handle this migration scenario? What's the best practice for developers to handle this case? Interestingly, both the old and new transaction IDs return the same JSON response from the App Store Server API, suggesting Apple maintains internal linkage between these transactions, but the appAccountToken isn't carried forward to the active transaction. Any insights or similar experiences would be greatly appreciated! Thank you!! Feedback Assistant: FB18709241
