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

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!

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 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

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?
