Hello, I have an existing app which is beeing sold in the app store since 2010. Now I want to convert this app into a free app with optional in-app purchases. A part of the functionality which paid users currently have should then be accessible only by IAP. Therefore, I must identify my existing customers, to not make them pay again for functionality they have paid already. Googling around reveals that this is not easy to do, if it was possible at all. However, I found this post: https://stackoverflow.com/questions/3735635/convert-existing-ios-paid-app-to-freemium-model-with-in-app-purchase Quote: "There is now an Apple-approved way to do this on both iOS and macOS. The originally downloaded version of the app can be obtained from the receipt using the info key Original Purchased Version. You can then decide whether to unlock features if that version predates the switch to IAP." Now I have played around with this a bit, or more precisely: NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL]; NSData *receipt = [NSData dataWithContentsOfURL:receiptURL]; However, in my tests, receipt will always be nil. The URL also points to some local location with sandbox in the name. Am I doing something wrong in general, or is this just not supposed to work how I thought it would? Note that I have installed my app from the app store on my device, then launched the above code on my device (so I'm NOT testing this in the simulator). I also read about SKReceiptRefreshRequest, however I cant figure out how to use it. So the question is, how would I figure out if a user has already purchased the orignal paid version? My app does not have a server-component, and by checking some NSUserDefaults key would result in charging users which reinstall the app on a new device. So what should I 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

Hi, Currently we are using store kit api and we get the receipt which then backend validate from apple using /verifyReceipt. Now we are planning to move to store kit v2 api. But in this case, we are getting signedPayload instead of receipt. Now this signedPayload cannot be used in the /verifyReceipt. So what is the other way to validate the signedToken from apple and get the data that we get from the /verifyReceipt response. Thanks for the help!

I am using local receipt validation and the SKReceiptRefreshRequest API to restore purchases. When my iOS 16.1 users tap "restore purchase", the call fails. Notably, it does not ask the users to log into their iTunes account (it normally does) and my app logs the following error: <SKReceiptRefreshRequest: 0x281b0ad20>: Finished refreshing receipt with error: Error Domain=ASDErrorDomain Code=603 "Request throttled" UserInfo={NSLocalizedFailureReason=Unified receipt is valid and current, NSLocalizedDescription=Request throttled, AMSServerErrorCode=0} These errors started showing up after the release of 16.1 and appear to be limited to that specific version of iOS. The relevant code has not changed in years and I have iOS 15 and iOS 16.0 users who are currently able to restore purchases without issue. Also, I am not able to reproduce the issue in the sandbox but I am able to do so in production. I'm a bit at a loss. Why would my request be "throttled" and, further, why only on iOS 16.1 and only in production? Any thoughts on what could be happening here? Any help is much appreciated. Thank you!

Ensure that your app’s local receipt validation is compatible with intermediate certificates that require using the SHA-256 algorithm. View Technote TN3138 >

Hello everyone I am testing receipt validation for an app to be submitted to the mac app store. After starting the app a login window popped up and I entered my regular apple id before realising I need to enter an apple id associated with a sandbox account. Now I can't get the login window to show again when starting the app, it seems as I am permanently (or temporarily?) logged into the sandbox account on the mac. How can I log out from the sandbox account? Is it even possible? Does the account time out after a while so that I just need to wait?

I am interested in using sandbox users for my automation, and I want to bypass the UI and execute the automation using the APIs. I have found the APIs to list users, modify users, and clear purchase history, but I am not sure if there is a way to create and delete users programmatically. https://developer.apple.com/documentation/appstoreconnectapi/sandbox_testers Currently, our app calls Apple to get the payment receipt, and then our internal workflows are triggered based on the response received from Apple. Is there a way to bypass UI and achieve the same thing using the backend APIs for sandbox user accounts? I also need some clarification on how to generate the JWT token for authorization purposes. Do I need to regenerate the JWT token every 30 days? Thank you for your time and consideration.

I am trying to calculate apple cut, if users days of paid service is more than a year apple reduces commission to %15. By the docs: If a subscription expires due to a cancellation or billing issue, the days of paid service stop accumulating. If the subscription is renewed within 60 days, the days of paid service resume from the recovery date. So can i assume if original_transaction_id stays the same user not violated 60 days, therefore if i sum all the (expiration_date - purchase_date) with that id, is it a viable result ? Thanks in advance.

Currently, my app validates App Store receipts on the device, so as per this news, I need to make changes to it, But I am unable to make a decision on where I should start, Can anyone please help me out on this? Do I need to make changes in the device receipt validation? If yes, what steps should I take? OR Should I do the receipt validation from the server side? If yes, then what steps to follow to make a receipt validation on the server? Your suggestions will be highly appreciated.

Hi, We offer a premium account IAP for our app. We recently noticed on our proceeds section of App Store Connect that a refund for the IAP had been processed but we didn't receive a notification regarding this and from what I can see there is no way to see who applied for it. This is a problem as we need to be able to switch the premium account off for that account. Can someone help with this please?

Can I delete the file StoreKitTestCertificate.cer if I have a published app that uses StoreKit 2? This is how I was using it earlier to do receipt validation but it's no longer in my released app: #if DEBUG let certificate = "StoreKitTestCertificate" #else let certificate = "AppleIncRootCertificate" #endif Source: https://developer.apple.com/documentation/xcode/setting-up-storekit-testing-in-xcode/ Can I safely delete StoreKitTestCertificate.cer in my next version this file without affecting the released app or TestFlight?

Issue Currently I have multiple subscription offers available for yearly/monthly subscriptions. Each of the subscription offers have multiple different custom codes available. When the customer buys a subscription and the receipt is being handled in the backend, I need to know which of the custom codes was used. What I have tried When i call the https://buy.itunes.apple.com/verifyReceipt I get the values offer_code_ref_name and promotional_offer_id. The offer_code_ref_name is the subscription offer name AND NOT the custom code. I tried to get more info using the https://api.storekit.itunes.apple.com/inApps/v1/subscriptions/{transactionId} request, but it does not give me any info about the custom code used either. I do however see which custom code has been used if I go to Sales and Trends > Sales and Trends Reports and download Subscritpion Reports. There the offer code can be found ref. as "Promotional Offer ID" my question How can I get which custom code was used when purchasing a renewable subscription using transaction id or transaction Receipt?

I'm noticing that when I build for development and switch Apple accounts while the app is running, the device receipt isn't updated even after I call SKReceiptRefreshRequest.start(). The app behaves as expected if I install fresh. Is this a known issue if we're running from Xcode?

In the old verifyReceipt endpoint doc, there is an important desc As a best practice, always call the production URL https://buy.itunes.apple.com/verifyReceipt first and proceed to verify with the sandbox URL if you receive a 21007 status code. Following this approach ensures that you don’t have to switch between URLs while your app is in testing, in review by App Review, or live in the App Store. So I can know the transactionId is for sandbox if return back 21007. And I am about to access to new App Store Server API, so the same, I wonder how can I recognize the transactionId is from sandbox by status code? The most likely desc is this: If you don’t have environment information, follow these steps: Call the endpoint using the production URL. If the call succeeds, the original transaction identifier belongs to the production environment. If you receive an [errorCode 4040005] with errorMessage as OriginalTransactionIdNotFoundError, (or HTTP response code 404 from the Send Consumption Information endpoint), call the endpoint using the sandbox environment. If the call succeeds, the original transaction identifier belongs to the sandbox environment. If the call fails with the same error code, the original transaction identifier isn’t present in either environment. And I have a try for Get Transaction Info API, but actually get 4040010, Transaction id not found. as return. So I just wanna clear that is there any doc clarify this point that I miss? Looking forward to your response, sincerely!! :)

I try to call Get Transaction Info from App Store Server API, and the transactionId is for a Non-consumable type product, but it is odd that there are so many different transactionId and they have a same originalTransactionId { "bundleId": "${bundleId}", "environment": "Production", "inAppOwnershipType": "PURCHASED", "originalPurchaseDate": 1691220528000, "originalTransactionId": "${originalTransactionId}", "productId": "${productId}", "purchaseDate": 1691220528000, "quantity": 1, "signedDate": 1692590989925, "storefront": "USA", "storefrontId": "143441", "transactionId": "${originalTransactionId}", "transactionReason": "PURCHASE", "type": "Non-Consumable" } the defination of Non-Consumable is can only purchase once for same apple account. But why there would have originalTransactionId?

If my user purchase and get transaction_id: 2000000395609292, and then another user just makeup a same transaction_id to call the App Store Server API If in the old way, the receipt seems impossiable to makeup, how about now? Is that equally safe as before? Or is there any way to protect transaction_id. I am not that good at security, so please forgive me about missing any point. o(╥﹏╥)o Looking forward to your response, sincerely!! :)

Hi all, We're facing an issue with our app's subscription and in-app purchases: We are using StoreKit 2 Up until 6 hours ago, everything was fine. Now, users are telling us they can't access what they've paid for. We could reproduce the error on iOS 16.6, not on iOS 17 developer beta Buying or restore purchases are timing out. Everything works fine in Sandbox and TestFlight. We are getting these two errors with production builds: Error enumerating unfinished transactions Error enumerating all current transactions both with the following timeout message: Error Domain=NSURLErrorDomain Code=-1001 "Zeitüberschreitung bei der Anforderung." UserInfo={NSErrorFailingURLStringKey=https://mzstorekit.itunes.apple.com/inApps/v1/history?reason=initial, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask, NSUnderlyingError=0x2837a4f00 {Error Domain=kCFErrorDomainCFNetwork Code=-1001 "(null)" UserInfo={_kCFStreamErrorCodeKey=-2102, _kCFStreamErrorDomainKey=4}}, _kCFStreamErrorCodeKey=-2102 Is anyone else seeing this? Any fixes? Thanks for any help or advice. Best, Juno

As of September 6, 2023, I have registered and paid the Apple Developer participation fee to be able to publish the application on the App Store. However, up to now, it has been 5 days since registering and I have not received any notification or response about my account status, even though Apple informed me in the message that I need to wait 2 days for processing. . I'm really frustrated, is there anyone else like me with this situation? If you have any way to solve the above problem, please help me. Thank you very much!

Hello, I finding contradictory information. Is it possible to place PWA in the app store?

The error message "Purchase of this item is not currently available. The item is being modified." keeps appearing for journalists in different countries trying to get early copies of the latest build of my app using promo codes. This error has only started appearing when redeeming promo codes recently. Just days ago, users had no problem redeeming codes for the same build. No changes have been made to the app since then. The app is also free globally with an in-app-purchase option to remove ads. The promo codes to remove ads have been working fine with no error messages, but redeeming the latest build displayed the error message though it has worked days before. Generating new promo codes for the same build did not work either. This is the message that I got from a reviewer from one journalist: "I've sent the code over to one of our reviewers, and he says that when he tried to redeem the code to download your app, an error message popped up saying "purchase not currently available, item is being modified". He's still getting the same error message even after restarting his iPhone. He even tried a different device and checked for updates on both devices to no avail. Can you help?" It's an urgent matter not only because the press can't review the game, but also I worry it would affect the launch of the app in a few days. What if this error means users can't download the app on launch?
