Hi All, We are trying to integrate Promotional Offer in our app, We have a React Native app and are using react-native-iap for handling our in app purchases, as per the documentation we are generating signature in our BE and passing the proper details to the function as well, but for subscription request which have offer applied we are getting the apple pop up properly as well with offer details but when trying to subscribe it gives us SKErrroDomain: 12, for subscription without applying offer the subscription goes through but when we apply the offer we get the above error. Our app is currently in Development Stages and has not been sent for review sam for our subscription plans as well. Please let me know what could be the probable cause for this and help us resolve the issue. This is the code snippet of ours for the front end : export const buySubscription = async (subscriptionData: any) => { try { if (subscriptionData.offer_id) { const response = await getSubscriptionSignature( subscriptionData.productId, subscriptionData.offer_id, ); const offerData = response?.data; const offer = { identifier: offerData?.offer_id, keyIdentifier: offerData?.key_id, nonce: offerData?.nonce, signature: offerData?.signature, timestamp: Number(offerData?.timestamp), }; await requestSubscription({ sku: subscriptionData.productId, withOffer: offer, }); } else { await requestSubscription({ sku: subscriptionData.productId }); } } catch (err) { logger.error('Subscription error: ' + JSON.stringify(err)); throw err; } }; and 
from my python Backend which generates the signature:

def generate_signature(self, product_id: str, offer_id: str) -> dict: """ Generate signature for Apple StoreKit promotional offers. Args: product_id: The product identifier from App Store Connect offer_id: The promotional offer identifier Returns: dict: Contains signature and required metadata Reference: https://developer.apple.com/documentation/storekit/in-app_purchase/original_api_for_in-app_purchase/subscriptions_and_offers/implementing_promotional_offers_in_your_app """ try: # Generate UUID without dashes and use as nonce nonce = str(uuid.uuid4()) timestamp = get_current_time_ms() # milliseconds # Create the payload string in exact order required by Apple payload_components = [ self.bundle_id, # App Bundle ID self.key_id, # Key ID from App Store Connect product_id, # Product identifier offer_id, # Promotional offer identifier nonce, # UUID without dashes str(timestamp) # Current timestamp in milliseconds ] payload_str = "\u2063".join(payload_components) # Use Unicode separator logger.debug(f"Signing payload: {payload_str}") # Create SHA256 hash of the payload digest = hashes.Hash(hashes.SHA256()) digest.update(payload_str.encode('utf-8')) payload_hash = digest.finalize() # Sign the hash using ES256 (ECDSA with SHA-256) signature = self.private_key.sign( data=payload_hash, signature_algorithm=ec.ECDSA(hashes.SHA256()) ) # Encode signature in base64 signature_b64 = base64.b64encode(signature).decode('utf-8') logger.info(f"Generated signature for product {product_id} and offer {offer_id}") return { "key_id": self.key_id, # Changed to match Apple's naming "nonce": nonce, # UUID without dashes "timestamp": timestamp, # As integer "signature": signature_b64, # Base64 encoded signature "product_id": product_id, # Changed to match Apple's naming "offer_id": offer_id # Changed to match Apple's naming } except Exception as e: logger.error(f"Failed to generate signature: {str(e)}") raise HTTPException( status_code=500, detail=f"Failed to generate signature: {str(e)}" )

There is a warning message displays in my itune connect's In App Purchase page but there is nothing highlighted in the table. This is very stange. Is there anyone having the same problem? Or can anyone help?

I'm currently still on StoreKit 1, and am testing the paymentQueueShouldShowPriceConsent delegate function. In my local .storekit file, I have a renewable subscription set up with a promotional offer. My test flow is as follows: User subscribes to renewable subscription Let subscription auto-renew once or twice User subscribes to renewable subscription with promotional offer with significant price reduction Promotional offer lapses and price increases to normal Expect paymentQueueShouldShowPriceConsent delegate function to trigger However, #5 never does get invoked, despite re-trying the subscription and promotional offers in various configurations. Manually triggering the Request Price Increase Consent option in the Xcode StoreKit transactions list does invoke the delegate function, but letting the promotional offer lapse does not. My storefront is set to Korea, and my simulator region is set to Korea as well. According to the documentation here and here, consent is required for all price increases in Korea. Is there some way I could check if things are working as intended?

Hello All, We continue to receive post backs for campaigns which were run 6 months back. Our understanding is post back window is only 3 months, so checking to see if this is expected or any documentation will help. We are on SKAN4.0

While testing an inapp purchase, if you purchase the same product twice from an account that does not have testflight permissions for the project and only has sandbox permissions, the second payment will receive the same transactionId as the first. Why is that so? I know transactionID is unique.

Hi, This is the first time I'm submitting an app using IAP with auto-renewing subscriptions. Everything keeps getting rejected (specifically, my subscriptions), and instead of telling me what's wrong or what I need to fix, my reviewer just keeps regurgitating generic passages from the rules. Is there a site/tutorial/whatever that explains how to set these up and submit them? I haven't found anything that looks official/legit, so I'll settle on something recommended by someone who has been through the process. I would appreciate any help. I have been at this for DAYS and am at my wits end. Thanks.

In my understanding, with the latest court ruling in the US, iOS apps may decide to support web-based payments for subscriptions and in-app purchases. However, are we allowed to exclusively support web-based payments and not implement StoreKit at all?

One of our customers subscribed to a monthly plan on August 16 but the server-to-server notification seems to have been sent on August 18. What could be the reasons for such a delay between the purchase and the server-to-server notification which are usually sent right after the purchase? The receipt sent along with the notification seems to confirm that the receipt has only been created 2 days after the purchase. Here is an extract: { "environment": "Production", "receipt": { "receipt_type": "Production", "bundle_id": "fr.gaumontvideo.gaumontclassique", "application_version": "613", "receipt_creation_date": "2025-08-18 13:00:16 Etc/GMT", "receipt_creation_date_ms": "1755522016000", "receipt_creation_date_pst": "2025-08-18 06:00:16 America/Los_Angeles", "request_date": "2025-08-25 13:08:27 Etc/GMT", "request_date_ms": "1756127307346", "request_date_pst": "2025-08-25 06:08:27 America/Los_Angeles", "original_purchase_date": "2022-05-11 06:14:37 Etc/GMT", "original_purchase_date_ms": "1652249677000", "original_purchase_date_pst": "2022-05-10 23:14:37 America/Los_Angeles", "original_application_version": "265", "in_app": [ { "quantity": "1", "product_id": "fr.gaumontvideo.gaumontclassique.subscription.monthly.apple", "transaction_id": "270002386706194", "original_transaction_id": "270002386706194", "purchase_date": "2025-08-16 08:02:06 Etc/GMT", "purchase_date_ms": "1755331326000", "purchase_date_pst": "2025-08-16 01:02:06 America/Los_Angeles", "original_purchase_date": "2025-08-16 08:02:08 Etc/GMT", "original_purchase_date_ms": "1755331328000", "original_purchase_date_pst": "2025-08-16 01:02:08 America/Los_Angeles", "expires_date": "2025-09-16 08:02:06 Etc/GMT", "expires_date_ms": "1758009726000", "expires_date_pst": "2025-09-16 01:02:06 America/Los_Angeles" } }

I have an Expo React Native application and I am using react-native-iap library. I have setup the URL for sandbox and production url to receive notifications when a something happens regarding subscriptions. I am not able to receive those notifications when I simulate the purchase on the Simulator using Xcode. I then have used the node library app-store-server-library to mock a test notification and I am receiving the test notification when I call requestTestNotification method. below is the react-native code I am using: import {useEffect, useState} from "react"; import { initConnection, Sku, Subscription, useIAP, SubscriptionIOS, requestSubscription, PurchaseError, clearTransactionIOS } from "react-native-iap"; import styles from "@/screens/IAP/IAPStyles"; import CustomText from "@/components/CustomText"; import Heading from "@/components/Heading"; import subscriptionsProducts from "@/utilities/products"; function IAPScreen() { const [isPurchasing, setIsPurchasing] = useState<boolean>(false); const [loading, setLoading] = useState<boolean>(false); const { subscriptions, currentPurchase, finishTransaction, getSubscriptions } = useIAP(); function RenderProduct({ item } : { item: Subscription }) { const iosSubscription: SubscriptionIOS = item as SubscriptionIOS; return( <View style={styles.productCard}> <CustomText customStyles={styles.productTitle} text={iosSubscription.title} size={"medium"} /> <CustomText customStyles={styles.productDescription} text={iosSubscription.description} size={"small"} /> <CustomText customStyles={styles.productPrice} text={iosSubscription.localizedPrice} size={"small"} /> <Button title="Purchase" disabled={isPurchasing} onPress={ () => HandlePurchase(iosSubscription.productId) } /> </View> ); } async function HandlePurchase(sku: Sku) { try { setIsPurchasing(true); await requestSubscription({ sku, andDangerouslyFinishTransactionAutomaticallyIOS: false }); } catch (error: any) { Alert.alert("Error", "Failed to purchase: " + error.message); } finally { setIsPurchasing(false); } } useEffect(() => { setLoading(true); console.log(`[${new Date().toISOString()}] Initializing IAP connection...`); const setupIAP = async () => { try { const result = await initConnection(); console.log(`[${new Date().toISOString()}] IAP connection initialized:`, result); await clearTransactionIOS(); await getSubscriptions({ skus: subscriptionsProducts }); } catch (error: any) { Alert.alert("Error", "Failed to load products: " + error.message); } finally { setLoading(false); } }; setupIAP() .finally(() => setLoading(false)); }, []); useEffect(() => { const checkCurrentPurchase = async () => { try { if(currentPurchase?.productId) { console.log("Current purchase: ", currentPurchase); console.log("Transaction Id: ", currentPurchase.transactionId); await finishTransaction({ purchase: currentPurchase, isConsumable: false, }); } } catch (error) { if(error instanceof PurchaseError) { console.log("Purchase error: ", error); } else { Alert.alert("Error", "Failed to finish transaction: " + error); } } } if(currentPurchase) { console.log("Finishing current purchase."); checkCurrentPurchase() .catch(error => Alert.alert("Error", "Failed to finish transaction: " + error.message)); } }, [currentPurchase, finishTransaction]); return( <View style={styles.mainContainer}> <Heading text={"Packages & Subscriptions"} type={"h2"} customStyles={styles.header} /> { loading ? <ActivityIndicator size="large" /> : subscriptions.length > 0 ?

Hello. I have setup a StoreKit testing in the app that was and still is perfectly working on iOS 18. Unfortunately when run on iOS 26 the following error gets printed in the console after calling Transaction.currentEntitlement(for:) method: Failed to verify certificate chain due to client recoverable failure: Error Domain=NSOSStatusErrorDomain Code=-67843 "“StoreKit Testing in Xcode” certificate is not trusted" UserInfo={NSLocalizedDescription=“StoreKit Testing in Xcode” certificate is not trusted, NSUnderlyingError=0x109de7e10 {Error Domain=NSOSStatusErrorDomain Code=-67843 "Certificate 0 “StoreKit Testing in Xcode” has errors: Root is not trusted;" UserInfo={NSLocalizedDescription=Certificate 0 “StoreKit Testing in Xcode” has errors: Root is not trusted;}}} I'm not seeting any StoreKit Testing certificates in phone's certificate trust settings.

Hello! I am trying to get my app set up to support external payments. The snag I am hitting at the moment is it seems that relevant pages are not accessible? There is this old EU doc https://developer.apple.com/support/apps-using-alternative-payment-providers-in-the-eu/ But the more updated US doc titled "Distributing apps in the U.S. that provide an external purchase link - Support" is not available where it should be https://developer.apple.com/support/storekit-external-entitlement-us/ In addition the link for requesting the entitlement seems to be broken https://developer.apple.com/contact/request/storekit-external-entitlement-us/ Any idea how one can access these? Perhaps this is just a temporary error?

Hello everyone, For example, our app currently has one subscription group in App Store Connect with 5 plans (2 annual, 2 monthly, and 1 quarterly). By default, users can go into Apple Subscriptions in Settings and freely switch between all of these plans. However, our business requirement is to only allow users to stay on one annual plan and one quarterly plan. We don’t want them to switch to the other plans. My questions are: Is there any best practice or recommended approach to restrict subscription switching within the same group? Would removing the unwanted products from sale be the correct approach, or are there any risks/downsides with this method? Has anyone faced a similar situation and found a practical solution? Any guidance or shared experience would be greatly appreciated. Thanks!

Hi Team, I’ve successfully implemented the subscription flow for my app. However, I’m currently facing challenges related to testing the cancellation behavior for auto-renewable subscriptions. Specifically: I’m unable to locate the correct payload structure for the following test endpoint: https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/test I’m also unclear on how to simulate or complete the full lifecycle of a subscription (including cancellation) using Apple’s sandbox environment or APIs. Could you please guide me on how to: Retrieve or construct the proper payload for the test notification API? Simulate a cancellation flow end-to-end in the sandbox for auto-renewable subscriptions?

Hello, Our app supports family sharing skus, we successfully ran tests on family sharing features in sandbox, we noticed the feature does not work on live builds. The family member (child account) do see the subscription as "Shared with you". We attempted to restore multiple time and there is nothing to restore.

アプリ内課金を実装しようとしていますが、サーバサイドのセキュリティに関してについて質問です。 StoreKit２を使えばアプリとApp Store Connect間のレシート検証は不要だが、 購入情報をサーバーで管理する場合は アプリからサーバーに購入情報を渡す際にレシート検証する必要があると考えるがその認識であっているか教えていただきたいです。

Hello Developers! I am trying to run a test In-App Purchase (IAP) for a renewable subscription product in the sandbox environment. I have set up everything required for sandbox testing, but it’s unclear whether the subscription product needs to be pre-approved by Apple for testing. If approval is required, I have already added the necessary metadata, but the status still shows "Ready for Submit." Additionally, when I save the page, a "Submit for Review" button briefly appears for a fraction of a second on the subscription page before disappearing. Is this button missing, or is there a known issue with this process? This is my first time running this test, and I would appreciate any pointers or suggestions. Thanks!

I am trying to launch a PWA as an application on App Store, and got rejected cause of In-App Purchases. Application is about content generation and selling subscriptions for premium content. So thats why needed to implement In-App Purchases. I have created wrapper via PWABuilder. And it is looking great so far, now my question is about How can I implement In-App Purchases in the bundle which is already created. Any suggestions will be appreciated. More clarification:- I have that product running on Web right now, we have integrated Stripe for payment handling for subscriptions. If there is nothing we can do for In-App Purchases then we have to make purchases on website and then user will be able to experience the changes. We tried that, but then we got rejected for showing locked premium content on user's feed. Also can't show any CTA or Subscribe text or button.
