Hello,
I’m integrating promotional offers for auto-renewable subscriptions using StoreKit 2.
The offer is displayed correctly, the Apple purchase sheet appears, and I can start the payment flow. The sheet shows the correct discounted price and the end date of the offer. However, after confirming the purchase, an alert appears saying “Unable to Purchase - Contact the developer for more information”
When dismissing the alert, Xcode logs the following:
Purchase did not return a transaction:
Error Domain=ASDServerErrorDomain Code=3902
"No se ha podido realizar la compra"
UserInfo={
NSLocalizedFailureReason=No se ha podido realizar la compra,
client-environment-type=Sandbox,
AMSServerErrorCode=3902,
storefront-country-code=ESP
}
Test environment:
App installed from Xcode on a real iPhone
Logged in with a Sandbox Apple ID
Using StoreKit 2
Promotional offer applied using:
Product.PurchaseOption.promotionalOffer(_:compactJWS:)
On the server side, I generate the promotional offer signature exactly as described in Apple’s documentation:
https://developer.apple.com/documentation/storekit/generating-a-signature-for-promotional-offers
The signature is generated using a Subscription Key
Signed with ECDSA + SHA256
Uses the correct invisible separator (U+2063)
The signature is validated locally using the derived public key and verifies correctly
The sandbox user has had previous subscriptions, which is why this promotional offer is eligible and shown.
Given that:
The offer is displayed correctly
The purchase sheet shows the discounted price and duration
The signature validates locally
The error occurs only after confirming the purchase
My question is:
Is this a known limitation or issue with promotional offers in the Sandbox environment?
Should promotional offers be tested exclusively via TestFlight instead of Sandbox?
Any clarification would be greatly appreciated.
Thank you!

Hello,
We are having an issue with the RequestReview API and were hoping to get some help. We know that there is no guarantee that the in-app review modal will show and we know that there are 3 circumstances in which it will definitely not appear:
if the user has turned off in-app review/ratings in their settings
if the user has submitted a review for that app on that device within the last 365 days
if the user has been asked for a review >3 times in the last 365 days
When testing our implementation, every single one of our testers did not receive the rating modal despite the fact that we had all our testers turn on the app rating setting and that we have never asked for reviews from our app before. So that seems suspicious. While it is possible that something is up with our code (and I have provided some snippets below) we are also concerned that apple maybe is suppressing it for another reason. We really want to go live with our app review code but unfortunately we are not able to get confidence that it will ever appear for the user. Can you please help us understand why this isn't working.
The code: We are using the SwiftUI approach to requesting review. Here are some relevant code snippets
Important to note, we have a modal that appears when the user is in our list of active, targeted users. If they tap yes on this modal, it should show the in app rate the app system modal. If they tap no, we present them with an airship survey so that they can give feedback. Here is the code for the Yes button action:
@Environment(\.requestReview) private var requestReview
private var yesButton: some View {
Button(
action: {
dismiss()
requestReview()
},
label: {
Text(Lingua.General.appRateFirstButton)
.regularParagraph()
.frame(width: 180, height: 35)
}
)
.customButtonStyle(
foregroundColor: .black,
backgroundColor: Color(.powderBlue),
radius: 36
)
}
and this is the logic we use to determine whether we want to show them the modal in the first place. Obviously, a lot of this code leads to deeper areas in our logic and code but to give an idea...
private func showAppRateModalIfNeeded() {
if preferencesManager.appRateReviewShown == nil,
accountManager.userAccount?.permissions.rateTheApp == true {
let appReviewModalVC = UIHostingController(rootView: AppReviewModal())
appReviewModalVC.view.backgroundColor = .init(white: 0, alpha: 0.6)
appReviewModalVC.modalPresentationStyle = .overFullScreen
appReviewModalVC.modalTransitionStyle = .crossDissolve
parentVC?.navigationController?.present(appReviewModalVC, animated: true)
preferencesManager.appRateReviewShown = true
}
}
When testing in debug, we do find that the modal appears and works as expected. However, on release builds nobody is able to trigger it. Why? Are we doing something wrong here or is Apple just suppressing it. We are thinking about implementing the button taking the user directly into the app store review but we'd prefer to do the lower-friction dialog in-app if we can get it work so the user doesn't get sent out of the app.

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’m implementing a subscription purchase flow using promo code redemption via an external App Store URL.
Flow:
User taps “Purchase” in the app (spinner shown)
App opens the promo redemption URL (apps.apple.com/redeem)
User completes redemption in the App Store
User returns to the app
The app must determine whether the subscription was purchased within a reasonable time window
The app listens to Transaction.updates and also checks
Transaction.currentEntitlements when the app returns to the foreground.
Issue:
After redeeming a subscription promo code via the App Store and returning to the
app, the app cannot reliably determine whether the subscription was successfully
purchased within a short, user-acceptable time window.
In many cases, neither Transaction.updates nor
Transaction.currentEntitlements reflects the newly redeemed subscription
immediately after returning to the app. The entitlement may appear only after a
significant delay, or not within a 60-second timeout at all, even though the
promo code redemption succeeded.
Expected:
When the user returns to the app after completing promo code redemption,
StoreKit 2 should report the updated subscription entitlement shortly thereafter
(e.g. within a few seconds) via either Transaction.updates or
Transaction.currentEntitlements.
Below is the minimal interactor used in the sample project. The app considers
the purchase successful if either a verified transaction for the product is received via Transaction.updates, or the product appears in Transaction.currentEntitlements when the app returns to the foreground. Otherwise, the flow fails after a 60-second timeout.
Questions:
Is this entitlement propagation delay expected when redeeming promo codes through the App Store?
Is there a recommended API or flow for immediately determining whether a subscription has been successfully redeemed?
Is there a more reliable way to detect entitlement changes after promo code redemption without triggering user authentication prompts (e.g., from AppStore.sync())?

If an app on the App Store still uses StoreKit 1 (a.k.a. the Original StoreKit) to handle In-App Purchases, would IAPs work for users who download such app on iOS 26.2?
Would the app allow the users to purchase an IAP via StoreKit 1 or would it be impossible to buy the IAP on iOS 26?
The iOS Documentation says that SKPaymentQueue (which is a part of StoreKit 1) is "Deprecated" and "No longer supported.", with the support being for iOS 3.0–18.0.
Does this mean that apps using StoreKit 1 won't be able to make IAP purchases when running on iOS 26?
Hello,
I am currently implementing External Purchase Link and External Purchase Custom Link and am encountering an issue where both
ExternalPurchaseLink.canOpen and ExternalPurchaseCustomLink.isEligible always return false under all test conditions.
I would like to confirm whether my setup is missing any required steps or whether this behavior is expected.
Below are the details of my current environment and configuration:
🔧 1. Development Environment
Xcode: 16.3, 16.4, 26.0 beta 4
Devices:
iPhone running iOS 26.2 beta
iPhone running iOS 16.7.12
macOS 15.5 (real device testing)
Simulator iOS 18.0
Build Type: Local development build using a Developer Provisioning Profile
Sandbox account signed in during testing
🔑 2. Entitlements (Developer site & Xcode)
In Certificates → Identifiers → App ID, both capabilities are enabled:
StoreKit External Purchase
StoreKit External Purchase Link
The .entitlements file in Xcode includes:
com.apple.developer.storekit.external-purchase = YES
com.apple.developer.storekit.external-purchase-link = YES
The Provisioning Profile also contains both entitlements (confirmed via codesign -d --entitlements :-).
📄 3. Info.plist Configuration
Both keys are configured with correct region codes according to documentation:
SKExternalPurchase
SKExternalPurchaseCustomLinkRegions
🌍 4. Test Storefront
Device storefront verified as United States (US) or Portugal (PT) (US = target region for External Purchase Link, PT = EU region)
But despite all the above configuration,
both API calls consistently return false:
ExternalPurchaseLink.canOpen // false
ExternalPurchaseCustomLink.isEligible // false
So I cannot proceed to testing the remaining flow (token retrieval, link opening, etc.)
------ Questions ------
❓ Q1) Local Development Build Limitation
Is it expected behavior that Developer-signed local builds always return
canOpen = false / isEligible = false
for External Purchase Link & Custom Link?
Is there a technical or policy restriction that prevents eligibility in local dev builds?
❓ Q2) App Store Connect Configuration Requirement
Are there mandatory App Store Connect settings (such as external purchase URLs, support URL, disclosures, or country configuration) that must be enabled before eligibility becomes true?
Currently, no External Purchase Link or Custom Link menu is visible in my App Store Connect app settings.
Is this menu only available after certain approvals or under specific conditions?
❓ Q3) TestFlight Requirement
Do External Purchase Link and Custom Link only return eligibility = true on:
TestFlight builds, or
Distribution-signed builds?
Or should eligibility also work on developer builds?
Formal confirmation would be helpful.
❓ Q4) Developer Account Type Limitation
We are using an Individual Developer Account (not Organization).
Can Individual accounts fully request, test, and ship apps using:
External Purchase Link
External Purchase Custom Link
Or are there limitations on account type?
🙏 Request
We have completed all documented setup steps (Entitlements → Provisioning → Info.plist),
but eligibility remains false, blocking feature validation.
Please clarify which of the following is the cause:
Local development builds do not support eligibility
Missing App Store Connect configuration (not visible to us)
Account type restriction
Region rollout or entitlement approval requirement
Any additional setup not documented publicly
Thank you for your assistance.
There is a project that has been running online for years. A few months ago, a player reported that after making their first successful IAP at a specific purchase point, any subsequent attempts to purchase the same item do not trigger the payment window. Instead, they get the error:"This in-app purchase has already been bought".After contacting Apple Support once, the player was able to make a payment, but the issue reappeared on the next attempt. So far, this is the only user reporting the problem, other people can purchase normally.
Question1:
Here’s what I’ve tried:
I reviewed the code and ensured that TransactionObserveris correctly called.
I’ve also added **[[SKPaymentQueue defaultQueue] finishTransaction:transaction]**in all possible places, but the issue persists.
According to the logs, after the user’s first purchase, every subsequent IAP attempt returns the same receipt from the initial successful transaction, even though I’m certain finishTransactionis being called. It seems like this method isn’t having the intended effect.
Question2:
I asked the player to manually trigger the Restore Purchases button by calling [[SKPaymentQueue defaultQueue] restoreCompletedTransactions].
the restoreCompletedTransactionsFailedWithErrorcallback returned the following error:
Error Domain=NSURLErrorDomain Code=-1200 "An SSL error has occurred and a secure connection to the server cannot be made."
The player has already checked their device time and tried switching between Wi-Fi and 4G, but the error remains. Is this SSL error related to the "already bought" error? Note that this SSL issue occurred during a separate restore process, not during a purchase attempt.
Question: 3:
I noticed that I’m not calling finishTransaction inside the restoreCompletedTransactionsFailedWithErrorcallback. Should I add it there?
Purchase Logs:
The player clicked "Restore Purchases" and then attempted another purchase. The purchase flow appears normal, but the IAP returns an old, already-used receipt.

Honestly, don't know how to test it in sandbox. I'm confused on if I need a sandbox to actually test out my in app purchase. Do I need to download something? Someone please help.

Hi,
I am experiencing an issue where my in-app purchase products cannot be fetched from App Store Connect during sandbox testing, despite all products being properly configured.
ERROR MESSAGE:
When testing on a physical iOS device, I receive the following error:
"Error fetching offerings - The operation couldn't be completed. (RevenueCat.OfferingsManager.Error error 1.) There's a problem with your configuration. None of the products registered in the RevenueCat dashboard could be fetched from App Store Connect (or the StoreKit Configuration file if one is being used)."
All products show status "READY_TO_SUBMIT" with the warning: "This product's status (READY_TO_SUBMIT) requires you to take action in App Store Connect before using it in production purchases."
I have 2 subscriptions and 4 Consumable in-app purchases set up in App Store Connect.
VERIFICATION COMPLETED:
Bundle ID matches exactly in App Store Connect, Xcode project, and RevenueCat dashboard
Product IDs match exactly between App Store Connect, RevenueCat, and application code
Paid Applications Agreement is signed and active (Signed on 12/9 morning, everything shows as active)
All products are in "Ready to Submit" status with complete metadata
All products are properly linked to the app in App Store Connect
Testing on physical iOS device (not simulator) with sandbox account signed in via Settings > Developer section
Products have been in "Ready to Submit" status for 8 hours
I have researched this error and verified the common causes (Paid Agreements, Product ID mismatches, Bundle ID mismatches) are all correctly configured on my end.
QUESTION:
Is this an issue on Apple's end, or are there additional requirements for products in "Ready to Submit" status to be available in sandbox testing? I have been unable to test my in-app purchases despite all configuration appearing correct.
Thank you for your assistance.

Hello,
I have a problem with a subscription: it is not recognised by my application (under TestFlight); it is as if it did not exist.
I have two subscriptions in the same group, a premium subscription that works perfectly and a basic subscription that is not recognised.
I have checked everything at least twenty times. Its status is ‘Ready to submit’.
I asked GPT 5.1 and Claude AI, but clearly both of their AIs are out of date and are giving me an obsolete procedure with App Store Connect options that don't exist.
Hi everyone,
I’m experiencing an issue with In-App Purchases during App Review.
What works
My consumable IAP products load correctly using StoreKit2.
TestFlight (sandbox) purchases work perfectly.
Localizations are filled in and valid.
Paid Apps Agreement, banking, and tax forms are active.
IAP products are properly created in App Store Connect and marked as “Developer Action Needed” only because they wait for approval with the new binary.
What fails
During review I received:
“We found that your in-app purchase products exhibited one or more bugs which create a poor user experience.
Specifically, we were not able to complete a purchase.”
They didn’t provide any more technical details.
Additional context
The StoreKit configuration file is not included in the app archive.
Product identifiers perfectly match those in App Store Connect.
StoreKit2 purchase() works as expected on TestFlight.
The app does not use server-side receipt validation - purchases are handled purely through StoreKit2 APIs, as recommended.
My questions
What could cause a situation where TestFlight purchases work but App Review cannot complete a purchase?
Does Apple expect server-side receipt validation even for simple one-time consumables?
Could there be a delay or sync issue causing IAP products to not be available to the reviewer yet?
Is there anything I should check on the App Store Connect side beyond what I already verified?
Any help or hints would be greatly appreciated - I’m stuck because everything works in sandbox but fails only for reviewers.
Thanks!
Hi there,
I have a plan of creating another app in the same niche, but I would like the actual subscribers to have access to the new app.
So the subscribers of App 1 don't need to subscribe to App 2.
Is that possible?

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.

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!
As a developer I have a question I would like cleared up. We offer two tiers of annual subscriptions in our apps. These subscriptions are under the same subscription group in App Store connect. My question is, if a user purchases tier 1 of the annual subscription for $10.00, and uses it for 6 months; then chooses to upgrade to tier 2 which costs $20.00 per year. Would the user be pro-rated the difference in price i.e. charge only another $10.00 at the time of the upgrade., or are they charged $20.00 and then refunded the difference in their remaining lower tier subscription? I keep finding inconsistent answers across the Apple community forums on this.
I have an iOS and iPadOS app that also runs on macOS Catalyst. The user is able to view their subscription using the SubscriptionStoreView with two SubscriptionOptionGroups.
The documentation does not mention these are supported on macOS Catalyst and the app crashes when attempting to show the SubscriptionStoreView on macOS Catalyst.
If not supported, how can the user manage their subscription on macOS?
Dear Apple Developer Support Team,
I hope you are doing well.
We are reaching out to request clarification and guidance regarding the In-App Purchase (IAP) requirements for our upcoming iOS application.
Our app offers paid access to digital video content. Each video has a dynamic price determined by our backend based on multiple factors (such as duration, category, and promotions). Additionally, users are allowed to select and purchase multiple videos at the same time, which results in a combined total price that varies per transaction.
Challenges we face with IAP on iOS
Dynamic pricing:
Apple requires IAP products to have static pricing defined in App Store Connect.
Our video prices change frequently and cannot be represented by fixed IAP product SKUs.
Multiple-item purchases:
iOS does not support a single purchase that includes multiple different IAP products.
Processing many separate IAP transactions in sequence results in a poor user experience and is likely to cause failures.
Product creation limitations:
Since our catalog contains many videos with frequently changing prices, it is not feasible to create individual IAP products per video.
Given these restrictions, we are unclear how to remain compliant while still providing a functional purchase flow for our users.
Question
In this scenario, where:
video prices are dynamic,
users may purchase multiple videos together, and
IAP does not support multi-item purchases or dynamic pricing,
are we allowed to use Stripe or another external payment provider to handle these purchases?
If not, we would appreciate Apple’s guidance on what the recommended and compliant approach would be for apps that must price digital content dynamically and allow bulk purchasing.
We want to ensure full compliance with App Store Review Guidelines and would like confirmation on the correct implementation strategy before proceeding.
Thank you for your time, and we look forward to your clarification.
Kind regards,
Muhammad Adnan

Hello — quick question about App Store Server Notifications migration.
We have a live app using Production V1 notifications for recurring in-app subscriptions. We plan to switch the Production webhook to V2. After the switch:
Will notifications for existing subscriptions be delivered in V1 format, V2 format, or will it depend (e.g., queued V1 retries vs new V2 deliveries)?
If V1 retries are queued, how long should we expect overlap/retries to continue?
Any recommended cutover best practices (support both formats, revert process, etc.)?
Happy to share additional details.
Thanks.

I’m implementing StoreKit External Purchase Custom Links (EU) and so far it is really painful. I am running into a strange, device-specific issue. On 3/4 devices it works. On one device I never get a token at launch nor before a transaction. isEligible is true everywhere. All devices have versions 18.5 and are located in Germany.
Info.plist: SKExternalPurchaseCustomLinkRegions is set to EU storefront codes and I have followed every step in the documentation: https://developer.apple.com/documentation/storekit/externalpurchasecustomlink
Good device: At launch → ACQUISITION = nil, SERVICES = token present. Works consistently.
Faulty device: At launch → ACQUISITION = nil, SERVICES = nil. Same before transaction. No token ever reaches my server from this device.
isEligible is true on both devices.
Any experts or help on the matter?
