Apple Pay Wallet API Access – Applied a Year AGO and Almost No Progress! Anyone Else?
Hey everyone, I wanted to check if anyone else has faced extreme delays when requesting access to Apple Pay Wallet APIs. It was Oct 11 2024 a year ago since we first applied to enable in-app provisioning for virtual cards in our app and we made 1% progress. For context, we already got access from Google for Google Wallet—it was smooth, professional, and timely. But with Apple… it’s been nothing but an endless cycle of waiting. We followed every step, submitted everything correctly, and even called Apple Developer Support multiple times. Their response? "We've escalated it." Again and again. But there’s no real progress. We’re rerouted, ignored, and left in limbo. At this point, I don’t even know if anyone is actually reviewing these requests. If a business like ours—fully compliant and ready to integrate—can’t even get a response in 150 day, how is this process supposed to work? I’m posting this here because I can’t be the only one. Has anyone else faced this? If you finally got access, how did you do it? Because right now, it feels like Apple Pay in-app provisioning is an impossible goal. Hoping someone from Apple sees this and realizes how broken this process is. We’re just trying to innovate and offer Apple users a great experience—why is it so difficult? Looking forward to hearing from anyone in the community who can help, Thanks! 🙏

Decrypting Apple Token
I am currently working on decrypting Apple Pay tokens with Laravel PHP, and I have encountered a few uncertainties regarding the decryption process and the usage of AES-GCM. Could you please clarify the following points: Algorithm Confirmation: Am I using the correct algorithm for decrypting the data key? Specifically, I am utilizing AES-256-GCM with the algorithm ID "id-aes256-GCM" (2.16.840.1.101.3.4.1.46), as specified in the documentation. Is this the recommended algorithm for decrypting the Apple Pay token's data key? Authentication Tag: In the decryption process, it seems that an authentication tag is required, but I am not sure where to obtain it from. Could you confirm how the authentication tag is generated or provided during the encryption process? If the tag is part of the token or is transmitted separately, could you clarify where I can retrieve it in order to proceed with the decryption successfully? IV and Other Parameters: I am using an initialization vector (IV) of 16 null bytes (00000000000000000000000000000000) as specified in the documentation. Could you confirm that this is correct and aligns with the expected parameters for the AES-GCM decryption? Are there any other specific parameters or considerations I should be aware of when implementing the decryption of Apple Pay tokens? GCM vs Other Encryption Modes: Can you confirm that AES-GCM is the preferred and required encryption mode, or is there any flexibility to use other modes (e.g., AES-CBC) without compromising security? Your guidance would be greatly appreciated to ensure I am following the correct decryption procedure for Apple Pay tokens. Thank you in advance for your support.

Apple Pay on the Web Merchant Validation Intermittent 403 Forbidden
We are experiencing intermittent 403 Forbidden errors during Apple Pay on web merchant validation in our production and sandbox environment. Has anyone else started seeing 403 Forbidden errors recently (since mid-2025)? Why would merchant validation be sometimes successful and sometimes fail with 403? Could this be related to new Apple Pay gateway changes or stricter validation rules? Any additional debug steps or permanent solutions we should try? Thank you.

Apply Pay or IAP for content
Hi everyone, I am new to Apply Pay, but I have already implemented IAP for subscriptions in my app. My app also has other functionalities, it also acts as a person-to-person marketplace, as users can post events or online courses which can be bought by other users to participate. My question is that I have read Apple's review guidelines but it is still unclear for me if I can use Apple Pay (with for example Stripe) or do I still need to use IAP for this online content. Also non profit organizations also can register which can recieve donations, can I also use Apple Pay for that or do I still need IAP there, because it would be nice if Apple would take 30% of donations.

HCE Permission and Background Access for Corporate NFC Integration
Hello, We are currently developing an application that uses the Host-based Card Emulation (HCE) entitlement to enable corporate access functionality. With this entitlement, we have successfully established HCE communication and can interact with our access control systems to unlock doors. Our question is related to improving the user experience: We would like this access functionality to work without requiring the app to be in the foreground, as this adds friction for users during entry. Specifically, we would like to know: Is it possible for our app to coexist with Apple Wallet as the default contactless app, so that: Our app handles NFC interactions for corporate access (e.g., opening doors). Apple Wallet remains the default for payments. If that coexistence is not possible, and our app is set as the default contactless app, Will the system still need to launch our app into the foreground to complete a transaction (e.g., to emulate the NFC card)? Or is there a way to trigger HCE responses in the background (e.g., using a background process or service extension)? Any guidance on how to configure the app for optimal background access behavior, while maintaining compatibility with Wallet, would be greatly appreciated. Thank you in advance.

Apple Pay button not clickable in Safari for some users
Hello, We’re seeing an issue where the Apple Pay button is visible in Safari but not clickable for certain users, while it works normally for others. This happens on our site (https://store-qa2.enphase.com/ ) as well as on other sites for the same affected users. Currently, we display the Apple Pay button based on the following condition: Boolean(window.ApplePaySession) && ApplePaySession.canMakePayments(); For affected users, the button shows up as expected, but it’s not interactive. All users (both affected and unaffected) are on the latest versions of Safari and macOS/iOS. Could someone clarify what additional conditions Safari/Apple Pay requires for the button to be fully functional? And under what circumstances could it be visible but not clickable?

Default payment method option bug?
Hi team at Apple, here is a scenario we came across: The order of priority of payment methods in Apple Wallet follows: Credit Debit Apple Cash Our app displays a payment sheet that excludes credit cards. Instead of a debit card, the default payment option shown to the user on the payment sheet is Apple Cash. Is this a known issue or have we configured something wrong in our end?

iOS Subscriptions in Russia – Is Apple In-App Purchase mandatory or can local providers be used?
Hello, We are working on integrating billing into our dating app, targeted at the Russian market. Our main requirement is to support subscriptions with automatic renewal and cancellation. We understand that, according to App Store Review Guideline, all digital subscriptions should use Apple In-App Purchase (IAP). However, we are unsure how this applies in Russia, where some local regulations may limit the use of non-Russian payment processors, and where not all Russian bank cards are accepted by Apple. Our question is: -For iOS apps in Russia, is it strictly required to use Apple IAP for subscriptions? -Are there any approved exceptions allowing integration with local processors such as Robokassa or YooKassa? -How are other developers currently handling subscriptions for the Russian market? We want to ensure full compliance and avoid any risk of rejection or removal. Thank you in advance for any clarification. Best regards, Dan

I am trying to get a pass reader certified through the mFi / WPC certification process. The problem I have is that the Certifier app will not allow testing results to be submitted due to some missing information. I need support to discuss the missing information, but I have received no replies from the email provided for WPC Certification Representative. Does anyone here know how to get support for the WPC Certification process?

DPAN, MPAN, Cryptogram and Compliance
Hello everyone, I’m currently in the process of implementing Apple Pay on my company’s e-commerce website under a subscription model with recurring payments. I would appreciate some help in clarifying the following points: Is the applicationPrimaryAccountNumber the DPAN and the merchantTokenIdentifier the MPAN? If not, which fields represent each one or how do I recognise them? Is the onlinePaymentCryptogram used only for processing payments with the DPAN, or is it also involved when using the MPAN? Is the onlinePaymentCryptogram single-use or does it have an expiration time? Or is it reusable with no limits? According to Apple’s data policies, is it recommended for our servers to perform the payment token decryption (debundling), or should this only be handled by the payment gateway processor to stay compliant? Below is the payment request I’m using for testing, along with the decrypted payment token returned for a test card: Payment Request: { "countryCode": "US", "currencyCode": "USD", "merchantCapabilities": ["supports3DS", "supportsDebit", "supportsCredit"], "supportedNetworks": ["visa", "masterCard", "amex", "discover"], "requiredBillingContactFields": ["postalAddress", "name"], "lineItems": [ { "label": "Subtotal", "amount": "9" }, { "label": "Taxes", "amount": "1" } ], "total": { "label": "Demo (Card is not charged)", "amount": "10", "type": "final", "recurringPaymentIntervalUnit": "month" }, "recurringPaymentRequest": { "paymentDescription": "Recurring payment", "regularBilling": { "label": "Demo (Card is not charged)", "amount": "10", "type": "final", "paymentTiming": "recurring", "recurringPaymentIntervalUnit": "month" }, "managementURL": "${window.location.origin}/api/managePaymentMethod" } } Decrypted Payment Token: { "applicationPrimaryAccountNumber": "5204240494898922", "applicationExpirationDate": "280630", "currencyCode": "840", "transactionAmount": 0, "deviceManufacturerIdentifier": "050110030273", "paymentDataType": "3DSecure", "paymentData": { "onlinePaymentCryptogram": "MCt5xR+VnQAAAAM/8mUjAAADFIA=" }, "merchantTokenIdentifier": "DM4MMC1US000000042e438d170774669844e732a41c28e97", "merchantTokenMetadata": { "cardMetadata": { "longDescription": "Test Bank for MasterCard MTF", "cardCountry": "US", "shortDescription": "Test Bank 2", "fpanSuffix": "0049" }, "cardArt": [ { "url": "https://nc-crt-smp-device-asset.apple.com:443/broker/v1/assets/174ce63257704d93b00aff8aa09ec0d5", "name": "cardBackgroundCombined@2x.png", "type": "image/png" } ] } } Thanks in advance for your help and guidance.

Adding a previous card to Apple Wallet and Express Travel Enabled
We are working with a large fintech org on project connected with provisioning payment cards to Apple Wallet. When we add a previously provisioned card to the Wallet (using the Wallet UI, Add card -> Previous card). It adds the card on one device showing the Express Travel card screen after the card is added allowing the user to set the card as an express travel card during the provisioning flow but never on our other devices. All of the test devices are clean and have only the same single card provisioned. What triggers the Express Travel Card screen to be shown during the add previous card flow? (Why is it showing on one device and not another).

Question Regarding API Access Restrictions for Non-Published (STG) iOS Apps
We have been informed by a third-party subscription tracking service(Adjust) that, due to the following specification of App Store Connect, it is not possible to connect an STG app (a non-published testing app) with their server: Specification: Since Apple’s API only allows access for apps that are already published, it is not possible to enable subscription tracking for iOS apps that are not yet published. Could you please confirm if our understanding of this specification is correct? Additionally, is there any method or recommended approach to verify subscription tracking behavior with an STG (non-published) app before the app is released? Thank you very much for your support.

Issue with Top-Up Flow on iPhone 14 Pro Max (iOS 18.6.2) in TestFlight
Hi Apple Team and Developers, I’ve been testing the Top-up flow in our app via the TestFlight environment. Across multiple devices (around 10 tested), everything works fine with no issues. However, on one specific device — iPhone 14 Pro Max running iOS 18.6.2 — I’ve noticed an intermittent issue: When performing a Top-up, the Apple UI first shows a successful purchase confirmation. Immediately afterward, another UI prompt appears asking the player to re-enter their Apple ID password. At the same time, Apple returns a ghost string that we cannot use to verify the user’s package bundle ID. This creates potential confusion for users, as they see both a success confirmation and an unexpected password prompt. I’m unsure if this behavior is expected or if there’s a recommended way to handle or prevent this issue. Has anyone else encountered something similar, or does Apple have a suggested fix/workaround for this? For reference, here’s a short video of the issue in action: \🔗 https://drive.google.com/file/d/1Ml-QpEu4ocoxn-W3wEMsFMbXy2QdwbHB/view?usp=sharing Any guidance would be greatly appreciated. Thank you for your support!

Unable to enable Apple Pay for App Clip – “relationship 'undefined'” error when adding capability
Hey everyone, hoping someone here has run into this before. I have a fully functional App Clip (com.didyoucatchit.app.Clip) linked to my main app (com.didyoucatchit.app). The Clip builds and runs perfectly, but I’m seeing issues trying to enable Apple Pay for it. When I try to link my Merchant ID under the “On Demand Install Capable” capability in the Apple Developer portal, I get this error: A relationship in the provided entity is not allowed for this request. The relationship 'undefined' can not be included in a 'bundleIdCapabilities' request. Here’s what I have already configured and confirmed: App Clip capabilities in Xcode include: Apple Pay Payment Processing Associated Domains (appclips:app.didyoucatchit.com) Provisioning profile includes: Apple Pay Payment Processing Associated Domains In-App Purchase On-Demand Install Capable Entitlements file for the Clip: <key>com.apple.developer.associated-domains</key> <array> <string>appclips:app.didyoucatchit.com</string> </array> <key>com.apple.developer.in-app-payments</key> <array> <string>merchant.com.didyoucatchit.app</string> </array> <key>com.apple.developer.parent-application-identifiers</key> <array> <string>$(AppIdentifierPrefix)com.didyoucatchit.app</string> </array> Merchant ID (merchant.com.didyoucatchit.app) is active and connected to Stripe Stripe Apple Pay configuration matches the same merchant ID and certificate Both provisioning profiles have been refreshed and downloaded However: The portal still throws the “relationship 'undefined'” error anytime I try to modify the Clip’s capabilities In testing, Apple Pay doesn’t show up as a payment option in the Clip (using Stripe’s Payment Element integration) Questions: Is this a known issue with the Developer portal when linking App Clips to merchant IDs? Is there a specific way to re-establish the parent–child relationship between the main app and the App Clip so the bundleIdCapabilities request includes the proper relationship JSON? Are there any additional configuration steps required when using Stripe for Apple Pay inside an App Clip? System Setup: Xcode: 16.2 (build 16C5032a) macOS: Sequoia 15.3.1 iOS: 18.5 (testing on physical device) Merchant ID: merchant.com.didyoucatchit.app Main App ID: com.didyoucatchit.app App Clip ID: com.didyoucatchit.app.Clip Any help or insight would be hugely appreciated Thanks in advance!
