Hi, Our app that implemented in-app payment has been reviewed and passed and is currently in operation. However, there is a problem with the App Store server notification V2. According to the url https://developer.apple.com/documentation/appstoreservernotifications/responding_to_app_store_server_notifications, it is written as follows. "When you set up the endpoints on your server to receive notifications, configure your server to send a response. Use HTTP status codes to indicate whether the App Store server notification post succeeded: Send HTTP 200, or any HTTP code between 200 and 206, if the post was successful. Send HTTP 50x or 40x to have the App Store retry the notification, if the post didn't succeed. The system considers all other HTTP codes an unsuccessful post. Your server isn’t required to return a data value. If the App Store server doesn’t receive a success response from your server after the initial notification attempt, it retries as follows: For version 2 notifications, it retries five times, at 1, 12, 24, 48, and 72 hours after the previous attempt." We are sending an HTTP status code to the Apple server by 200 or 40x or 50x when we receive an Apple notification from the server as per the document. Nevertheless, Apple Server continues to send us 5 times App Store server notifications for each transaction. I would appreciate it if you could share how we can do it. Also, we can provide the implementation code of our server through code-level support. Thank you for your support.

Hi, We previously scheduled a price change (which did NOT affect existing subscribers) however months later, we have now made a decision to apply the increase to all subscribers. As the price has not increased, I only see the option to preserve and isn't obvious if this has any effect on those grandfathered in the lower price. Can anyone confirm or must I increase the price again?

Is it possible to initiate an iap flow from App Clips? There's not a clear answer to this in the docs. StoreKit is NOT listed as an unapproved framework for App Clips, but in-app purchases ARE listed as "not recommended" for App Clip functionality. I tried setting up a test with a StoreKit config file on the App Clip in XCode and the products weren't returned but... storekit testing... it would be great to get confirmation on this functionality after the iOS 17 updates.

Hey everyone, I'm facing a bit of a puzzling issue with the review of my app, particularly with the in-app purchase functionality for message extension/sticker packs. I've implemented the entire store using StoreKit for in-app purchases, using exactly the same code like it is in Apple's demo application (https://developer.apple.com/documentation/storekit/in-app_purchase/implementing_a_store_in_your_app_using_the_storekit_api). Here's the problem: the products appear correctly according to what's set up in App Store Connect (In-App Purchases section), and the purchase process works flawlessly in sandbox and TestFlight environments. However, during the review process, I received the following feedback: "Guideline 2.1 - Performance - App Completeness We found that your in-app purchase products exhibited one or more bugs which create a poor user experience. Specifically, the app kept loading indefinitely when we tapped on “Shop”. Please review the details and resources below and complete the next steps." It seems that the products are not loading properly in the environment used by the reviewers. What's most puzzling is that another app with the exact same store implementation has passed the review and is available in the store (https://apps.apple.com/pl/app/the-prince-frog/id6478831171?l=pl). I'm running out of ideas on what could be causing this discrepancy, especially since everything is functioning correctly in sandbox and TestFlight. Could someone please take a look at the code in Store.swift in this demo project and point out what might be missing? Any help or insights would be greatly appreciated! Thanks in advance. @MainActor func requestProducts() async { do { //Request products from the App Store using the identifiers that the Products.plist file defines. let storeProducts = try await Product.products(for: productIdToEmoji.keys) for product in productIdToEmoji.keys { toDebug = toDebug + ", " + product } var newCars: [Product] = [] var newSubscriptions: [Product] = [] var newNonRenewables: [Product] = [] var newFuel: [Product] = [] //Filter the products into categories based on their type. for product in storeProducts { switch product.type { case .consumable: newCars.append(product) case .nonConsumable: newCars.append(product) case .autoRenewable: newSubscriptions.append(product) case .nonRenewable: newNonRenewables.append(product) default: //Ignore this product. print("Unknown product") } } //Sort each product category by price, lowest to highest, to update the store. cars = sortByPrice(newCars) subscriptions = sortByPrice(newSubscriptions) nonRenewables = sortByPrice(newNonRenewables) fuel = sortByPrice(newFuel) } catch { print("Failed product request from the App Store server: \(error)") errorMessage = error.localizedDescription } }

I implemented a store kit in my application, which was working fine until the last three months. Recently, we have encountered an issue where the store kit screen automatically dismisses when attempting to purchase an in-app product using the UPI payment method. This issue specifically occurs with consumable products. Our non-renewable products are working fine with the same code base.

We have identified Subscription Groups for our use-case based on the below note from Apple, but there is no mention of any limitations in the doc. Can we create unlimited number of Subscription Groups or is there a limit? If your app needs to offer users the ability to buy multiple subscriptions — for example, to subscribe to more than one channel in a streaming app — you can add these subscriptions to different groups. Users who buy subscriptions in multiple groups will be billed separately for each subscription. Thanks in advance!

When using the new currentEntitlementTask ViewModifier to check for the status of a non-consumable IAP when should you call transaction.finish()? Also, since currentEntitlementTask will trigger whenever the app/view is run it will call transaction.finish every time. Is it bad to repeatedly call .finish on a already finished transaction? Currently my app works fine when making purchases and using currentEntitlementTask and @Environment to grant access to the purchased content but I know that all the transactions are unfinished and the docs say you should call transaction.finish() to tell StoreKit that you have given the user access to the content. Thanks for any help/advice here.

Do we require a Vietnamese bank account to receive payments from in-app purchases for our new educational app being developed in Japan, or will the funds be automatically transferred to our Japanese bank account?

I have already created consumable in-app purchases in App Store Connect which are available in my app. Then I created a "Discount Code" UIButton which presented custom UI for the user to input a code for another in-app -purchase at a lower price but that build was rejected because you cannot have custom code for this sort of thing. Ref: Apple Documentation: presentCodeRedemptionSheet() Finally I got it through review when I changed the UI but then I realized that I can't offer a free consumable in-app purchase. The minimum price is US$0.29. I would prefer a free consumable in-app purchase to give to freelancers I am owkrin with for them to test the app with. I know that there are ways to do it when using subscriptions but my app only using consumable in-app purchases which align better with my business model and the value offering of my app. There must be some way of creating a single-use free consumable discount code which will also get through App Store Review. Anyone managed something like this? Thanks.

Hello Apple Developer Community, I am currently working on an xCode project that uses Objective-C and I am trying to integrate Apple's external purchase link APIs available in iOS 15.4. To use these APIs, I need to utilize async and completion handlers which are available from iOS 13 onwards. The issue I'm facing is that the current minimum deployment version for my project is iOS 12. I would like to ensure my code compiles properly for the correct iOS versions and I am also using #if available; to ensure this. However, I am unsure of how to guarantee my code builds effectively with the deployment version being set to either iOS 12 or 13. I am currently facing the following linker errors: ld: warning: Could not find or use auto-linked library 'swiftCompatibility56': library 'swiftCompatibility56' not found ld: warning: Could not find or use auto-linked library 'swiftCompatibilityConcurrency': library 'swiftCompatibilityConcurrency' not found ld: warning: Could not find or use auto-linked library 'swiftCompatibilityPacks': library 'swiftCompatibilityPacks' not found ld: Undefined symbols: __swift_FORCE_LOAD_$_swiftCompatibility51, referenced from: __swift_FORCE_LOAD_$_swiftCompatibility51_$_ProjectXYZ in ProjectXYZ.a[20](ExternalPurchaseLinkWrapper.o) __swift_FORCE_LOAD_$_swiftCompatibility56, referenced from: __swift_FORCE_LOAD_$_swiftCompatibility56_$_ProjectXYZ in ProjectXYZ.a[20](ExternalPurchaseLinkWrapper.o) __swift_FORCE_LOAD_$_swiftCompatibilityConcurrency, referenced from: __swift_FORCE_LOAD_$_swiftCompatibilityConcurrency_$_ProjectXYZ in ProjectXYZ.a[20](ExternalPurchaseLinkWrapper.o) clang: error: linker command failed with exit code 1 (use -v to see invocation) I would appreciate any guidance or advice on this matter. How do I ensure my code compiles and works only for the correct versions and how do I resolve the linker errors? Thank you in advance for your assistance. Best, Sumanth

If an in-app purchase is made when my app is not running, the next time the app launches Transaction.updates will emits a transaction for the purchase. That's great. But if an in-app purchase is refunded when my app is not running, the next time the app launches Transaction.updates will NOT emits a transaction for the refund. Is that the expected behaviour? If yes, in order to check for refunds at app launch, are we supposed to cycle trough Transaction.all and search for them? Thank you

Below, I have a button designed to facilitate the purchase of a subscription, which depends on the availability of the subscription in App Store Connect. This button is visible when testing locally using a StoreKit Configuration File synced from App Store Connect, and I have linked my subscription to my app in the information section. Currently, my app is in a "waiting for review" status, and the subscription is marked as "developer action needed - rejected." However, this issue of the button not appearing persisted even when the subscription was previously in the "waiting for review" status, indicating that the problem may not be related to the subscription status. I'm encountering an issue where the 'request products' function returns no results in the TestFlight environment, even when using a sandbox Apple ID. This problem has led to repeated rejections of my app, as testers are unable to verify its functionality. What could be causing these issues? VStack { if storeVM.subscriptions.isEmpty { if storeVM.isLoading { ProgressView("Loading subscriptions...") .progressViewStyle(.circular) .scaleEffect(2.0) .padding() } else if let errorMessage = storeVM.errorMessage { Text("Error: \(errorMessage)") .foregroundColor(.red) .padding() } else { Text("No subscriptions available") .padding() } } else { ForEach(storeVM.subscriptions, id: \.id) { product in Button(action: { Task { await buy(product: product) } }) { HStack { Spacer() Text("Unlock 3-day free trial. \nThen $23.99 per year. Cancel anytime.") .font(.custom("Lora-VariableFont_wght", size: 20)) .foregroundColor(.white) .lineSpacing(5) Spacer() } } .padding() .background(Color.black.opacity(0.6)) .cornerRadius(10) .padding(.horizontal, 10) } } .onAppear { Task { await storeVM.requestProducts() } } func requestProducts() async { isLoading = true errorMessage = nil do { subscriptions = try await Product.products(for: productIds) isLoading = false } catch { print("Failed product request from App Store server: \(error)") isLoading = false errorMessage = "Failed to load products" } }

I entered Setting > App store section. But ı cannot see anything about sandbox account. What should ı do?

I would like to programmatically keep track of offer codes that have been used. I just configured a Test Offer Code (Reference name), which contains 500 codes (Offer Codes) to buy a 1-month subscription for 0,49€. I was able to redeem the code and everything works, but I was expecting to receive the used code. Instead I received the Reference name in the payload from the App Store Server Notification in the field offer_code_ref_name="Test Offer Code". (expected was sth like offer_code_ref_name="JFFDS61SBJDBJ5BXJS4BX") I would be able to identify the Reference name by the code, if it was provided, because I have the following table in my app's backend: reference_name | code | url | expires_at | used | reserved Test Offer Code | xadz | zzz | 31-07-2022 | t | f Test Offer Code | asdf | *** | 31-07-2022 | f | f The used code doesn't seem to be included in the latest receipt. How can I obtain it? Can I somehow call App Store Connect API? Thanks

I am not sure if this is just Xcode and Storekit2 behaving weird. I am getting all products every time during my testing, even though I have pricing enabled for US and non-US in the same subscription group. How do I handle this scenario? Isn't SubscriptionStoreView supposed to handle this by itself depending on media and purchases country? Thanks in advance for your response!

On Testflight the SubscriptionStoreView() is loading endlessly (see Image below). In Xcode it works. What could be the problem?

I need user installed app information like first install time (purchase to install) last time use "Bundle.main.appStoreReceiptURL" to request Receipt was successful but when i Reinstall the app by Xcode has ERROR:"Error reading receipt data: Error Domain=NSCocoaErrorDomain Code=260" what wrong with ERROR?

When the user finish the Product.purchase in ios, I get an transaction id in the client side. But how can I use the App Store Server API to confirm this transaction whether it is in success status or not in server side? thanks

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?

As an indy developer, it's prohibitive to start developing backend receipt validation services. Is there anything else in Apple's technologies that we can use to verify whether the person who is using my app, has paid for it? The first thing I thought of when Apple rolled out Sign in with Apple ID, was hopefully, it would include some API that would allow me to ask a simply question: did this Apple ID pay for my app? As an indy developer, this is the one feature that would keep my paid app on the Mac App Store. Anyone have any good suggestions for solving this as an indy developer?
