💬 Post Content Hello everyone, I’m currently testing In-App Purchases (auto-renewable subscriptions) for my iOS app, and I’m experiencing an issue where the product information cannot be fetched from StoreKit. ❓ Questions For sandbox testing, is it absolutely necessary to submit a new app version for review (with the in-app purchase included)? Or can I test subscriptions without submitting a new build to App Review? Under what conditions does the error IAPError(code: storekit_no_response, source: app_store, message: StoreKit: Failed to get response from platform.) 🧪 What I’ve Tried • Confirmed that the bundle identifier matches the App Store Connect record • Verified that In-App Purchase capability is enabled in Xcode • Ensured the sandbox tester account is logged in (Settings → App Store) • Removed the StoreKit configuration file to use the sandbox environment • Tried both real device and simulator (same error) • Accepted the Paid Apps Agreement in App Store Connect • Products are created but currently not yet submitted for review 🔍 Environment • App type: iOS app built with Flutter (using in_app_purchase plugin) • Build type: Archive build installed via Xcode (Run on device) and testFlight • StoreKit Configuration File: Currently removed (for sandbox test); • Status: Ready to submit in App Store Connect

On this page: https://developer.apple.com/documentation/storekit/testing-age-assurance-in-sandbox It says: Start with a Sandbox account. What is a Sandbox account and how does one set one up? Just it just simply mean an Apple account id used for testing, or something else?

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.

I’m implementing App Store subscriptions using StoreKit 2 and testing in the Sandbox environment. Until about a week ago everything worked fine, but recently the Settings > Subscriptions screen shows this message for my test account: “Your current payment method is not available.” The behavior: • Using a Sandbox tester account (not a production Apple ID) • Purchase flow works successfully — the transaction completes, and I receive server notifications • However, the system Settings app still displays that message under the subscription entry • No code changes were made since it last worked Questions: 1. What exactly does this message mean in the Sandbox environment? 2. Could this be related to any Apple system issue or recent backend update? 3. Has anyone else seen the same behavior in recent days? Environment: • Xcode 15.4 • iOS 17.5 (physical device) • StoreKit 2 / Swift 5.10 • Sandbox tester (Japan region) Thanks in advance for any insights or confirmations from others who are testing subscriptions in Sandbox!

We have encountered an issue when verifying transactions using the Get Transaction Info API. We tested the behavior in both the sandbox and production environments and observed the following results. When calling the production endpoint: https://api.storekit.itunes.apple.com/inApps/v1/transactions/{transactionId} with a transactionId generated in the sandbox environment, the API returns HTTP 401 Unauthorized. However, based on the documentation and common understanding, we expected HTTP 404 Not Found in this case. Using the same JWT token, if we call the sandbox endpoint: https://api.storekit-sandbox.itunes.apple.com/inApps/v1/transactions/{transactionId}, we receive HTTP 200 OK with the expected response body. We have also confirmed that the same behavior occurs when using the Get Transaction History API — it works correctly in the sandbox environment but returns 401 in production. Could you please confirm whether this behavior (receiving 401 instead of 404) is expected by design, or if it indicates a potential issue? If this is not the intended behavior, we would appreciate any guidance or instructions to resolve it. Thank you very much for your technical support. 「Get Transaction Info」APIを用いてトランザクションの検証を行ったところ、以下の問題が発生しました。 サンドボックス環境および本番環境の両方で検証を行い、次の結果を確認しています。 本番環境エンドポイント https://api.storekit.itunes.apple.com/inApps/v1/transactions/{transactionId} に対して サンドボックス環境で生成された transactionId を使用すると、HTTP 401 Unauthorized が返却されます。 （一般的には、この場合 404 Not Found が返る想定であると理解しています。） 同一のJWTトークン を用いて サンドボックス環境のエンドポイント https://api.storekit-sandbox.itunes.apple.com/inApps/v1/transactions/{transactionId} を呼び出した場合は、HTTP 200 OK が返り、期待通りのレスポンスボディを受け取ることができています。 また、同様の挙動が Get Transaction History を使用した場合にも発生することを確認しています。 サンドボックス環境では正常に動作しますが、本番環境では401が返却されます。 この挙動（401が返却されること）は仕様上想定されたものか、または何らかの問題によるものかご確認をお願いいたします。 もし想定外の挙動である場合は、解決に向けたご案内をいただけますと幸いです。 本件について、技術的なサポートをお願いいたします。 よろしくお願いいたします。

Hi everyone, I’m facing an issue where StoreKit is returning 0 products from the App Store, even though my auto-renewable subscriptions are approved in App Store Connect. When calling queryProductDetails using Flutter’s in_app_purchase package (which uses StoreKit under the hood), StoreKit reports success but returns an empty list. The logs show the following error: IAPError(code: storekit_no_response, source: app_store, message: "StoreKit: Failed to get response from platform.") InAppPurchase.isAvailable() returns true, but no product details are received. Already verified: • Subscriptions are approved in App Store Connect • Product identifiers in the app match those in App Store Connect exactly • In-App Purchase capability is enabled in Xcode • Paid Applications Agreement, banking, and tax details are active and complete • Using the latest version of the Flutter in_app_purchase package StoreKit should normally return the list of available products in the production environment, but it consistently returns an empty array along with the “storekit_no_response” error. Has anyone else encountered this issue or found any potential causes for StoreKit failing to return products in the production environment? Any insights would be greatly appreciated. Thank you.

I’m testing auto-renewable subscription purchases in the sandbox environment. When I buy a subscription package using a sandbox test user, I don’t receive any Apple Server Notifications from the sandbox. However, when I use the Request Test Notification option in App Store Connect, the notification is received successfully. My sandbox server notification URL is configured correctly and publicly accessible. I also call finishTransaction() after purchase. It looks like sandbox purchase notifications are not being sent, even though the test notification works fine.

Hello Fellow Developers, I recently built a simple craft related app called "Genie Crystals" with a landing page. there is a button on landing page which redirects to a main template generator page. Here the user can play with the parameters and create an output which can be exported. to export there is an unlock button which is linked to the in-app purchase configured in the app. Initially it was not capturing price properly so I modified the code slightly to keep the button in disabled state until the product details got fetched in background asynchronously. But when I released the app and downloaded it on a different device at the time of load itself, I am getting the alert - product not available. I have used correct product Id in the program. I have confirmed that. I think I am missing something. Any help will be appreciated. I am new to this so if I need to share any additional information kindly let me know. Thanks.

Hey guys, somehow I used my real ID(not sandbox test ID) to purchase a non-consumable item in the TestFlight package, no actual payment was made, but this payment record cannot be erased. Even though I know the transaction ID, I cannot initiate a refund like using refundRequestSheet(). Does anyone know how to deal with this, or there is no way to solve it?

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?

Hi, I have a setup using App Store Server notifications, which has worked fine for a while now. However, I've never been able to successfully verify a purchase via Xcode, only via TestFlight. The reason for this is that the StoreKit transactions have numerical IDs (e.g. starting from 0, incrementing one-by-one), instead of UUIDs like in TestFlight/production. This means that often the backend will detect an existing transaction with the same ID and not complete the purchase. What are we meant to do here? If I send a custom ID to make it unique the backend won't accept this - I can ask them to change this for our dev environment but it's not ideal. What I'm after is a way to use UUIDs for transaction IDs when running via Xcode. Thanks

Hey! We're implementing In-App Purchase Subscriptions and we were able to receive "App Store Server Notifications" on our "Sandbox Server URL". But the last event we received 22 hours ago. We are able to verify transactions and finish them, but receive no webhooks. We changed nothing on our server or its configurations but the notifications stoped to come. We consulted the API (https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/history) and it says the same as we see - the last event was 22hrs ago. I checked all the advices from here as well (https://developer.apple.com/forums/thread/805806?answerId=864483022#864483022). Is there any Status page for the Store Kit Sandbox services? Was there any outage? Sincerely, Konstantin

Hi there! Whenever I try to add a new Offer Code for my app's subscription, I get an unknown error. When I get to the last step of the "Create Offer for Codes" flow, I get an error that error reads "An error has occurred. Try again later." I have been getting this same error for over a week now, so any help figuring out how to add new offer codes would be greatly appreciated!

I’m testing auto-renewable subscription purchases in the sandbox environment. When I buy a subscription package using a sandbox test user, I don’t receive any App Store Server Notifications from the sandbox. However, when I use the “Request Test Notification” option in App Store Connect, the notification is received successfully. My sandbox server notification URL is configured correctly and publicly accessible. I also call finishTransaction() after purchase, and the receipt is verified successfully with the sandbox verification endpoint. To further debug, I used the getNotificationHistory API to fetch notifications for yesterday and today (Nov 3–4, 2025). Apple’s API response does not include any notifications or transaction IDs for my today’s purchases (Nov 4, 2025) — even though I can confirm from logs that those transactions were completed and verified successfully. It looks like sandbox purchase notifications are not being sent or logged, even though test notifications work fine. Could someone from Apple please confirm if there’s currently an issue with sandbox server notifications for auto-renewable subscriptions?

Previously I could get the sub package information after each payment via webhook but today I didn't get it. What happened? My webhook url: https://r-connect-api-dev.mystg-env.com/webhook/appstore/notification/v2

We got Advanced Commerce API and the generic product identifiers approved. When I was try to migrate a sandbox subscription to ACA enabled subscription I hit an error Request payload (Hid some info but the requestReferenceId is the real) { "descriptors": { "description": "Migrated", "displayName": "Migration" }, "items": [ { "sku": "product_1mo_999", "description": "description", "displayName": "Product" } ], "requestInfo": { "requestReferenceId": "3b0b8e67-d8a0-45f4-8f6d-06bffa9a2c08" }, "storefront": "USA", "targetProductId": "com.company.generic.subscription", "taxCode": "C003-00-1" } Response { "errorCode": 5000000, "errorMessage": "An unknown error occurred." }

According to Apple's documentation, SKOverlay is designed to recommend other applications to users. I'm seeking clarification on whether it also supports displaying update prompts for the host application itself. Use case: My app (for example, HelloDeveloper) is live at version 2.0, but some users are still on version 1.0. I want to display a soft update prompt that allows users to remain in the app. Question: Is it possible to use SKOverlay with my app's App Store ID to present an update option without requiring users to leave the app?

I've been testing the offer code feature for my non consumable in app purchase using a sandbox account, with sandbox offer codes and in the sandbox environment. However, the codes don't appear to work despite everything being in the sandbox. Any idea what I'm missing?

Currently, we are using the Apple V2 interface to develop the payment function. We generate a transaction ID on the mobile client and obtain the receipt. Now, when we call the Apple sandbox environment interface to verify the receipt, we always get a 404 error. The above is the request and response. The token used in it is also the original data after decoding, and there is no problem. Could you help me figure out what other possible reasons there might be?
