Can you implement storekit2 for in app purchases for a flutter project?

is there a way to make a test subscription in-app purchase expire immediately, for faster testing? it seems exceedingly complicated to test subscriptions if we have to a) wait until the next day for expiry, or b) keep on creating new apple ids to get into a fully unsubscribed state? it is still kind of madness testing this stuff, after all the years it has been available.

I want to test the "Remove from Sale" scenario in Sandbox. I set my subscription to "Remove from Sale" for all territories in App Store Connect, but I can still make new purchases and auto-renewals continue in the Sandbox environment. Is this a known limitation? Or is there a specific way to make this work for testing? If it can't be tested, I'd like to know the expected production behavior. What changes occur in the App Receipt and what App Store Server Notification is sent?

We are seeing an issue with a potential duplicate charge issue regarding our app. We have received two transactions with the same originalTransactionId but different transactionIds: Order A: TransactionId: [Redacted_TID_1] OriginalTransactionId: [Redacted_OID_A] ProductId: weekly_subscription PurchaseDate: [Redacted_Timestamp_1] SignedDate: [Redacted_Timestamp_2] Price: [Redacted_Price] CAD Order B: TransactionId: [Redacted_TID_2] OriginalTransactionId: [Redacted_OID_A] ProductId: weekly_subscription PurchaseDate: [Redacted_Timestamp_1] SignedDate: [Redacted_Timestamp_3] Price: [Redacted_Price] CAD Both transactions share the same originalTransactionId, productId, and expiresDate, but the transactionIds are different. We wanna confirm: Were customers charged once or twice for this subscription renewal? If only one charge was made, how should we programmatically determine the “valid” transaction among multiple records with the same originalTransactionId to avoid confusion in our server-side receipt validation? We appreciate any clarification so we can handle this correctly in our backend.

Hello, I'm suddenly encountering errors with In-App Purchases (IAP) and my sandbox webhooks, which were working correctly just a few days ago. Specifically: Product Information Error: I'm receiving the following error when trying to fetch product information: { "type": "product_info", "result": "error", "error": "An unknown error occurred" } This API call was functioning normally until today. Sandbox Webhook Failure: I have configured a sandbox webhook, but my server is not receiving any notifications from the App Store. Test API 401: When I attempt to call the test API (https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/test), I consistently receive a 401 (Unauthorized) error. Could you please provide some guidance on how to troubleshoot these issues? Thank you.

Dear App Store Engineering Team, I am writing to request official confirmation regarding the behavior of App Store Server Notifications when migrating a live application from V1 to V2. Context: Our application has been live since 2008 and currently utilizes App Store Server Notifications V1. We have a large database of existing legacy subscribers. We are preparing to switch our Production environment setting in App Store Connect from "Version 1" to "Version 2". Our Questions: When we change the setting in App Store Connect to Version 2: Global Format Switch: Does this setting apply immediately to ALL notifications, including those triggered by subscriptions that originated years ago (legacy users)? Payload Consistency: Will renewals for existing legacy subscriptions continue to arrive in the JSON V1 format, or will they immediately start arriving in the V2 JWS (signedPayload) format? Our expectation is that the switch is global and all future notifications (regardless of subscription age) will be sent as V2 JWS payloads, but we require official confirmation to ensure our backend handles the migration without service interruption. Thank you for your assistance.

Product.SubscriptionInfo.isEligibleForIntroOffer(for: "21340582") In the production environment, I have already used the intro offer for this group, but this method still returns true

Product.SubscriptionInfo.isEligibleForIntroOffer(for: "21340582") In the production environment, I have already used the intro offer for this group, but this method still returns true.

Regarding the offer codes in https://developer.apple.com/help/app-store-connect/manage-subscriptions/set-up-offer-codes, I set up some incorrect offer codes by mistake. Currently, I can only deactivate it but I can't delete it. Is it possible to let me delete the incorrect offer codes due to the below reasons? Thank you. I can't recreate the offer code due to error message This reference name is or has been used by another offer in this subscription group. When I use the offer code redemption view in https://developer.apple.com/documentation/SwiftUI/View/offerCodeRedemption(isPresented:onCompletion:), it shows all the deactivated offer codes. I don't want them to be displayed in the page.

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?

After downloading Backyard Birds and following the steps in the section "Configure the sample code project" (i.e. enabling local StoreKit testing in the scheme). When I run the macOS app from within XCode, the following error occurs. Whenever I try to purchase any item from within the app, I am presented with the following error dialogue: "Couldn’t communicate with a helper application. Try your operation again. If that fails, quit and relaunch the application and try again." This happens after I click the purchase button (i.e. the button that displays the price). The Xcode logs show the following errors: Error handling payment sheet request: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service created from an endpoint was invalidated from this process."

We’ve recently observed an escalating number of complaints from AlipayHK users regarding duplicate charges when completing transactions via Apple Pay. While no similar issues have been reported by users of other credit card providers integrated with Apple Pay, the problem appears isolated to AlipayHK transactions. Key Details: Multiple users confirm being charged twice for single transactions. Complaints are increasing in frequency, indicating a potential systemic issue. No overlapping reports from non-AlipayHK payment methods at this time. To safeguard customer trust and ensure seamless payment experiences, we kindly request Apple’s support in: Investigating whether the root cause stems from Apple Pay’s transaction handling. Collaborating with AlipayHK (if necessary) to resolve the issue promptly. Providing guidance on interim measures to prevent further duplicate charges. Could Apple confirm if this is a known issue and share a timeline for resolution? We’re eager to assist in any way possible to mitigate impact on users. Thank you for your urgent attention to this matter.

Hello all, I am new to implementing payments in an app, and thus completely at sea here. I have created a small app that I have set a one-time (non-consumable) payment for a premium version. In the Xcode simulator (on all platforms) and on any physical test devices I have tried, the payment works as expected. I have a sandbox account and various test accounts, both dummy and actual real accounts (friends and family). Everywhere everything works perfectly fine. Yet, when I submit for review I get a rejection with this contents: We found that your in-app purchase products exhibited one or more bugs which create a poor user experience. Specifically, the app still failed to load the in-app purchase. Please review the details and resources below and complete the next steps. Review device details: Device type: iPad Air (5th generation) OS version: iPadOS 18.6 Next Steps When validating receipts on your server, your server needs to be able to handle a production-signed app getting its receipts from Apple’s test environment. The recommended approach is for your production server to always validate receipts against the production App Store first. If validation fails with the error code "Sandbox receipt used in production," you should validate against the test environment instead. Additionally, note that the Account Holder must accept the Paid Apps Agreement in the Business section of App Store Connect before paid in-app purchases will function. Resources Learn how to set up and test in-app purchase products in >the sandbox environment. Learn more about validating receipts with the App Store. Steps I have done: I have signed all agreements and all bank account details are in order. Everything in the In-app-purchases section of the AppStoreConnect in an Active state. I have triple checked that the configuration of the in-app purchases is correct (product IDs, amounts, etc.) I have created test accounts and tested in sandbox What I don't understand from the reviewer's response is what receipts validation are they talking about? I have no payment servers (the whole concept of using Apple's in-app-purchases service is to not have to deal with my own payment implementation). The StoreKit documentation specifically reads: For each transaction that represents a current purchase, your app delivers the purchased products. To validate purchases, you can verify transactions on your server, or rely on StoreKit’s verification. So now I am confused. The reviewer's response is so vague, and so completely deprived of details that I have no idea what to do... Does the problem concern the product purchase trigger and the that in production environment it does not trigger? Is it that I haven't implemented a receipt validation? Do I need to? Although the documentation mentions that it can be done by StoreKit, I couldn't find anything concerning how to do it :( Can someone give me a hand please? Cheers, Alex

Hello Developer support, In one of our live application we have seen that users are purchasing weekly subscription and automatically they shifted to yearly product. Due to this we have received high revenue and also refunds afterwards. To prevent this we removed our yearly product from the sale. In App Store Connect we have seen activations for weekly product and convert to standard prices are yearly products. Also we have seen weird behavior of user getting trial for same product for three times. For developer support people I am sharing my app id - 1320373866 , and here is the video of our issue - https://drive.google.com/file/d/1DBHw8ivgql4eNoo8NC3xo5v4wgr8Oh7x/view?usp=sharing , Also attaching trial behavior screenshot.

Hi All i have developed an app but when I go to download the paywall appears as it’s subscription only but it shows no prices for the subscription I get an endless swirl. I checked the product id etc and it’s correct but the subcription on my App Store Connect shows as approved. is there another status it needs to reach before it becomes like like ready for sale? https://apps.apple.com/gb/app/gameaware-pro/id6751592563

The appTransactionID was recently introduced and is documented here: https://developer.apple.com/documentation/storekit/apptransaction/apptransactionid From the documentation: "The App Store generates a single, globally unique appTransactionID for each Apple Account that downloads your app and for each family group member for apps that support Family Sharing." This seems like a really useful identifier, so I was wondering about some edge cases of when using it: What happens if a user logs out of his AppStore account and keeps using the app? Is it available when the app is installed from Xcode? is it possible to set it to some value using StoreKit testing? Thanks

アプリに課金を実装しようと思うのですが、もし不正利用された場合、アプリ側は基本的にApp Storeを通じて対応するよう案内するのが一般的と思いますが、Apple ID不正利用時とクレジットカード不正利用時で、アプリ側が行う標準的な対応プロセスは変わるのか教えていただきたいです。 また下記内容は標準的な対応プロセスとして問題ないでしょうか？
 ■Apple ID不正利用時 → ユーザー自身がAppleサポートに連絡し、パスワード変更・二段階認証の設定・不正購入の返金申請などを行うよう案内する。 ■クレジットカード不正利用時 → まずカード会社への連絡を促すが、アプリ内決済に関してはAppleのカスタマーサポート経由で返金や調査手続きを案内する 不正利用されたユーザーへの対応に備えて、アプリ側が考慮すべきことがあれば教えてください。

Dear Apple Developer Support, Our iOS application offers subscriptions with a free trial period. We understand that in South Korea, due to local subscription regulations, users must explicitly provide consent for recurring payments before the subscription converts from a free trial to a paid period. We have the following questions regarding how StoreKit handles this scenario: When a free trial is about to convert to a paid subscription for a user in South Korea, does StoreKit send a StoreKit.Message (or SKStorefront.Message) to the application to obtain the required consent for recurring payments? If such a message is sent, would the Reason for this message be StoreKit.Message.Reason.priceIncreaseConsent, or would it be another specific reason related to initial recurring payment consent after a trial? If our application receives such a message and we choose to defer its display, what is the maximum recommended or permissible deferral period? Is it possible to save the data of a received StoreKit.Message and display it to the user at a later time, for instance, after the application has been closed and subsequently reopened? Are there any best practices or limitations regarding this? We need this information to ensure our application correctly handles these consent requirements in compliance with South Korean policies and provides a smooth user experience. Thank you for your guidance.

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.
