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.

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://aninterestingwebsite.com/forums/thread/805806?answerId=864483022#864483022). Is there any Status page for the Store Kit Sandbox services? Was there any outage? Sincerely, Konstantin

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!

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

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.

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?

I’m reaching out regarding our existing in-app subscription implementation that currently uses App Store Server Notifications version 1 (v1). Our live application has a significant number of active recurring subscriptions that are being managed through the v1 webhook integration. We have now developed a revamped version of our application, which uses the same Apple Developer Account and App Store Connect setup, but in this new app version, we’ve implemented App Store Server Notifications version 2 (v2). Before moving forward with the migration, I would like to clarify the following points to ensure a smooth transition and avoid any disruptions to ongoing subscriptions: Backward Compatibility: Will existing active subscriptions (originally created and managed via v1 notifications) continue to work seamlessly once we switch to v2, or do we need to maintain both v1 and v2 endpoints during the transition? Notification Delivery: If both webhook versions are configured simultaneously, will Apple send notifications to both endpoints, or only the one currently configured in App Store Connect? Migration Strategy: What is Apple’s recommended best practice for migrating from v1 to v2 in a scenario where the live app still has active subscriptions tied to the v1 webhook? Potential Risks or Considerations: Are there any known limitations, delays, or issues that we should prepare for during this migration (for example, differences in payload structure or event types between v1 and v2 that could affect subscription lifecycle management)? I would greatly appreciate your guidance or documentation links that outline the correct migration steps and recommended approach for ensuring continuity of service for all existing subscribers.

According to the App Store Server API documentation , https://aninterestingwebsite.com/documentation/appstoreserverapi/price the price field "shows the total amount of the transaction for the quantity the customer purchased." However, in actual transaction notifications and responses from App Store Server API, the price field appears to represent the unit price, not the total price. For consumable in-app purchases with quantity > 1, the price field equals the unit price of a single item. The total user payment is only correct after multiplying by the quantity. When quantity > 1, the actual amount paid by the user only matches price × quantity, which contradicts the documentation. Please confirm whether the price field is intended to be: The unit price of a single item (requiring multiplication by quantity), or The total price including all quantities (as currently documented). If the former is correct, please update the documentation to clarify that the value represents the unit price, not the total amount.

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, is it allowed to include the action=write-review URL parameter in customer support emails to direct users to the App Store review page? Example: https://apps.apple.com/app/id[APP_ID]?action=write-review I want to make it easy for customers to leave feedback after positive support interactions, but only if it's compliant.

Apple review says , my app displayed an error when we attempted to purchase subscriptions. Please review the details and resources below and complete the next steps. Device type: iPad Air (5th generation) OS version: iPadOS 26.0.1 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. Question: Is it due to Device being used by reviewer or is it really from my code. As my code relies on Apple infrastructure for purchases and all things. Initially i did had subscription reporting api for receipt handling and all.When i went through with ChatGPT it did say that issue is due to half baked subscription module on my server. So i decided not to send any Subscription related things to backend, now it's Apple only and on App side. Is it correct fix ? Or do i need to fix backend even though i have no use for it ? My team did test in sandbox env via internal testing that time we had no issues. And all was tested using Mobile devices, that's why i still have question just to be sure these errors are due to devices or not? Screenshot shared by Apple team did show they got a error popup saying Something went wrong : Unable to complete request. I am trying to reproduce in development but can't. Anyone had got same issue before and has information on how to resolve and test for it will be helpful. Thanks Shikhar Sahu

Hello, I’m facing an issue with auto-renewable subscriptions in my React Native iOS app using react-native-iap. Before App Store approval, everything worked perfectly — I could test in-app purchases and subscriptions locally on my iPhone through Xcode using a development build and sandbox tester. After the app was approved and released on the App Store, I needed to make some updates. Now, when I build and run the same project again through Xcode (Debug, development-signed) on my iPhone, the subscriptions no longer load. The same product IDs are approved and live in App Store Connect. The live version on the App Store works fine (subscriptions load and process successfully). But on the local Xcode build, getSubscriptions() returns invalid product identifiers or an empty list. No changes were made to the bundle ID or product IDs The build is signed with an Apple Development certificate and uses the same team and bundle identifier as the published app. “In-App Purchase” capability is enabled. I’ve also tried deleting the app, rebooting the device, and re-logging into a sandbox tester account, but the issue persists. It looks like the sandbox environment no longer works for the app after its first App Store release. Has anyone experienced this issue where the same approved app’s IAPs work in production but fail to load in sandbox/dev builds through Xcode after release? Any guidance on re-enabling sandbox testing for updates would be greatly appreciated. Environment: Xcode 26.0.1 React Native with react-native-iap Auto-renewable subscriptions (3 SKUs) Thank you!

Hi does anyone have trouble using expo store review package for ios apps. for some reason on our app., the review may show for certain people, but when they submit a review, it doesn't update our review count

We've been approved for the Advanced Commerce API. After receiving the approval, we completed the initial setup requirements (submitted a generic product ID and shared our subscriptions page deep link). When testing the Migrate Subscription to Advanced Commerce endpoint in the sandbox, we receive a 5000000 error. What could be the reason/s for it? There is no information, and the API call we make includes all required parameters. Could it be related to the fact that our new generic product ID status is "Missing Metadata"? Is there a way to understand what the issue is on Apple's side?

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." }
