I want to sell the same subscription in multiple apps so that if someone subscribes in one they show up as having a subscription in the other. Apple's documentation states "To get started, use App Store Connect to create a separate and equivalent auto-renewable subscription for each app that offers the multi-app subscription so that users can subscribe from any app." (https://developer.apple.com/documentation/storekit/in-app_purchase/original_api_for_in-app_purchase/subscriptions_and_offers/offering_a_subscription_across_multiple_apps) But I'm unable to create two subscriptions with the same Product ID. I could create two subscriptions that are equivalent but with different Product IDs that are treated as the same by our server, which would accomplish the main goal, but I believe this risks someone subscribing to both subscriptions if they do so directly through the App Store, for example using a promo code link, because they're still two different subscriptions to Apple. Thanks!

I am working on the integration of subscriptions in my OSX application. The subscription flow works perfectly but after the purchase it is not creating _MASReceipt folder in Contents folder of application so I cannot send the receipt to apple to verify this purchase. when I checked the logs it showing below error. Anyone who is familiar to this issue please help.

We are currently experiencing an issue where our server is not receiving Apple’s server notification (webhook) for in-app purchase confirmations. This notification is critical as it helps us confirm the purchase status and fulfill the corresponding services to the users. Despite the successful completion of purchases within the app, the lack of webhook notifications prevents us from tracking and processing these payments on our backend. In addition to resolving this issue, we are also concerned about the security aspect of receiving server notifications. Specifically, we want to ensure that any requests or notifications we receive are indeed coming from Apple, and not subject to potential man-in-the-middle (MIM) attacks. We are looking for information or best practices on how to validate that the request originates from a legitimate Apple source, ensuring the integrity of the communication and safeguarding our system from spoofed or malicious requests. Key questions: Server Notification Issue: Why might we not be receiving Apple's payment confirmation notifications, and what steps can we take to troubleshoot this issue? Request Validation: What security mechanisms or validation techniques can we implement to confirm that the server notifications are genuinely from Apple, ensuring no interference from MIM attacks? Does Apple provide any headers, tokens, or signatures in the server notification that we can use to verify the origin? Are there any known methods or configurations to ensure secure receipt of in-app purchase confirmations? We are looking for guidance and possible solutions to ensure a secure and reliable payment validation process for our in-app purchases. Any support in this regard would be highly appreciated.

I have got from App Review Team this same feedback during several months: Guideline 2.1 - Performance - App Completeness We are unable to complete the review of your app because one or more of your in-app purchase products have not been submitted for review. Next Steps To resolve this issue, please be sure to take action and submit your in-app purchases and upload a new binary in App Store Connect so we can proceed with our review. I am unable to understand and implement what is meant by the feedback: … take action … What "action" to take? … submit your in-app purchases … How to "submit in-app purchases"? I know how to submit my app but how "submitting in-app purchases”? My app contains no separate in-app purchases but several pathways through the app. The app's code contains three flags that act as signposts on user’s way through the app (Basic, Standard, Premium). The signposts are not extra content and features distributed on the App Store. They are existing parts in the app from the very beginning. They are activated according to the model user chooses (Basic, Standard, Premium) and loads down from the App Store. I try to solve the problem since several months - without success. Links offer no solution. Links say what one can do but not how to do it. What is missing are a couple of lines of code I can adapt and integrate into my app's Objective-C code. Best regards gefa

I work as QA and we develop mobile farm game. Inside our game we have shop where user can buy coins or special prem.coins. And interface shows price with Apple Tax. Also we have battle pass, and when user want to buy battle pass the price shows without Apple tax. Anybody knows what is wrong? Pass price inside game > 9.99$ Price when user want to buy it > 11.99

Hello! Since October 2, we have observed a problem with the renewal of subscriptions. We have not changed anything, but the receipts no longer have the information whether a valid subscription exists after the subscription was actually automatically extended. The subscription status can then be queried correctly via verify Receipt. Has anything been changed to the receipts from Apple? PS: we know that StoreKit1 is deprecated and we should switch to StoreKit2 asap.

Hi, we had a case where one of our users wanted us to stop renewing his subscription in our app since he was unable to do it himself. Is there a way for us to stop the auto renewal? Kind regards Ondřej Leitmančík

Hello, I have a customer who keeps getting an "app is damaged" error for a freshly downloaded app from the Mac App Store. The logs show the following lines: standard 12:58:40.390872+0200 storeuid Receipt Validation (at.EternalStorms.Yoink) Signature Check: PASS Bundle ID Check: PASS Bundle Version Check: PASS GUID Check: PASS Expiration Check: PASS standard 12:58:40.391649+0200 storelegacy StoreLegacy: Failed to perform in-line receipt renewal for application at path /Applications/Yoink.app : '(null)' The Mac in question is running macOS 12 Monterey - curiously, the customer has another Mac with that same system version and there it works just fine. What can be done to make this work again? Thank you, – Matthias

Hello, I hope to find out more about how AppTransaction works on macOS, specifically about its internet connection requirements: if I use this to validate that the app is a legit purchase from the Mac App Store, I would not want it to have an always-on requirement just to validate. Does AppTransaction require the user to always be online for AppTransaction.shared ? When an app is downloaded from the Mac App Store, is the data needed for AppTransaction automatically embedded during that download, or is that data downloaded upon first launch of the app, therefore requiring an internet connection at launch time? Once the data/receipt has been downloaded by AppTransaction, is it cached until the app's next update, or is it cleared at some time during the version's life and needs to be re-downloaded, therefore requiring an internet connection at launch? Where is that receipt/data stored? Also, if you don't mind me sneaking in this non-related but sort of related question, in terms of receipt validation: Does macOS Sequoia's MAC address rotation feature affect receipt validation in any way when using IOKit? Thank you kindly, – Matthias

Over 50 hours ago, we created an app update with 4 IAP:s. We use revenue cat for the payment features. All IAP:s are approved, and they were bundled into this version. Still, none of the IAP:s are working. They work as intended on TestFlight. All of them are approved. I have reached out with a case to apple developer support but have received no assistance. This is a really frustrating situation and there are no logs or any ability to understand what is going on.

I have 2 subscriptions, monthly and year first：DID_CHANGE_RENEWAL_PREF + DOWNGRADE： Customer downgrades a subscription within the same subscription group； The current subscribe is year；if i change to month；when the subscribe year was expire，Automatic renewal will change to month second：DID_CHANGE_RENEWAL_PREF+UPGRADE： Customer upgrades a subscription within the same subscription group. The current subscribe is month；if i change to year；I need to pay for the annual subscription immediately；and The subscription immediately switches to the annual third：DID_CHANGE_RENEWAL_PREF subtype is None Customer reverts to the previous subscription, effectively canceling their downgrade. what this mean?

Since today, we are receiving reports from several customers on iPadOS17.x and iPadOS18 that their app runs in 'demo' mode. This can only happen if the purchase receipt is not found and this also shows in the log file they sent us. We can also reproduce it on an officially installed version of our app, but not when run from Xcode. Is anyone else experiencing this?

Hi I'm writing my first in-app purchase app, and I'm trying to do some testing with sandbox accounts. I wrote my subscription page use SwiftUI SubscriptionStoreView. And I read the documentation it says : The sandbox account appears in Settings > App Store after the first time you use the device to attempt a purchase in a development-signed app. But I have no idea how to make a sandbox purchasing. Every time I click the subscription button it just making a purchase in xcode environment. Did I missed anything? What can I do to make a sandbox pruchasing?

I have an app that allows users to complete a video call and then bills them a per-minute charge for the length of the call. How can I automatically bill my app user using in-app purchase without prompting for approval? I'm using Stripe on the web to complete an automatic purchase with the user's stored credit card. How do I accomplish the same thing on the web while on Apple device (or within my app) without prompting them for approval? They've already given approval by completing the call. I am aware that I can create an in-app purchase product for the necessary "credits" but this will prompt them to complete the purchase which should instead be automatic. Thanks!

Hello, I have an app where the users can connect their vehicles to an API and record trips and so on. Currently I have one subscription, where the user can add as many vehicles as he wants. But now I want (need) to change this to one vehicle per subscription. So if the user want to add two vehicles, he need to subscribe two times to the same product. How can I handle this? Thanks, Arangoool

My app is planning to develop a subscription product, for this type of in-app purchase do I need call finish() to complete the transaction? And, does currentEntitlements() return the transaction after calling finish()?

I would like to know if it is possible to use the PIX payment option, a Brazilian payment method, for in-app purchases. Additionally, I would like to know if it is already possible to integrate other payment APIs such as MercadoPago, Iugu, etc.?

Which scenario does SKErrorOverlayCancelled refer to specifically? If the user pulls up the payment and cancels it, does it return SKErrorPaymentCancelled or SKErrorOverlayCancelled?

Some paid users are unable to use the paid features unlocked by purchasing our subscription plan. It seems that this is due to StoreKit 2's Transaction.currentEntitlements not working the way we would expect it to work. Are you also encountering this issue? Do you have any idea to improve this situation? At launch, our app checks if the user is subscribed to the plan, using Transaction.currentEntitlements. As a result, the currentEntitlements array was empty. Our app then fetches the products from StoreKit 2 using Product.products(for:). As a result, the Product.SubscriptionInfo.RenewalState value of the corresponding Product (product.subscription.status.first.state) is subscribed, which confirms that the user has indeed purchased our plan, but seems to contradict the absence of the corresponding transaction in Transaction.currentEntitlements. Proactive in-app purchase restore and a restore purchase button calling the AppStore.sync() method are implemented, but using the button did not solve the issue.

Hello We are developers of a long-running game series and now reports have started to come in that users who install any of our previous games from the Mac App Store on OS X Sequoia are shown a popup claiming "The exit(173) API is no longer available". It's actually a lie, the mechanism is still there, the receipt generation still works and the game still runs afterwards. But the popup is confusing to users therefore we need to update the code. Apparently the replacement for the old receipt generation mechanism is AppTransaction which does not exist for Objective C. We have attempted to use it using the Swift/ObjC interoperability and failed so far. The problem is that we need to call async methods in AppTransaction and all our attempts to make this work have failed so far. It seems as the actor/@MainActor concept is not supported by Swift/ObjC interoperability and without those concepts we don't know how to pass results from the async context to the callers from ObjC. The lack of usable information and code online regarding this topic is highly frustrating. Apple really needs to provide better support for developers if they want us to continue to support the Mac platform with high quality games and applications on the Mac App Store. We would appreciate if anyone can cook up a working sample code how to use AppTransaction in ObjC. Thanks in advance!
