PKPassLibrary returning empty array in Non-UI Wallet Extension
Hello, We are implementing Apple Wallet extensions (PKIssuerProvisioningExtensionHandler). While our UI extension works as expected, our Non-UI extension is unable to detect payment passes provisioned by our app. Specifically, PKPassLibrary().passes(of: .secureElement) returns an empty array when called from the Non-UI extension, even though the same call correctly returns the passes when executed from the Main iOS App. Our Payment Network Operator has confirmed that our extension bundle identifiers are correctly registered in the metadata on their side. They suggested that the Wallet Extensions entitlement (com.apple.developer.payment-pass-provisioning) may require additional backend enablement for these specific Extension App IDs. Is there a known reason why PKPassLibrary would behave differently in the Non-UI extension vs the Main App? Beyond the standard entitlement request, is there a specific process to "activate" these IDs for extension visibility? Does anyone have guidance on reaching the appropriate team for backend entitlement activation issues? Any insights would be greatly appreciated.

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.

How does the Domain Verification Files work
Currently, on our Production environment, when calling https://apple-pay-gateway.apple.com/paymentservices/paymentSessio,n we are randomly receiving: "Payment Services Exception merchantId={Value} unauthorized to process transactions on behalf of merchantId={Value} reason={Value} is not a registered merchant in WWDR and isn't properly authorized via Mass Enablement, either." Since launching Apple Pay on our platform we have received a new Domain Verification File and looking at some of the Domain Verification File that are hosted on the domains they are different to ours. Questions around the Domain Verification File Would we have to update every single Domain Verification File every time we receive a new one ? Does the paymentSession verfiy/call the Domain Verification File on the domain listed at https://[DOMAIN_NAME]/.well-known/apple-developer-merchantid-domain-association ? What happens if the Domain Verification File doesnt match the one that we currently have ? Would we have to regrester our Domains everytime we get a new Domain Verification File ?

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!

UNEXPECTED_CANCEL_AFTER_completeMerchantValidation
Hi, We are trying to make payment from ecomm merchant. The last request during process is { "sessionData": { "epochTimestamp": "1741082241", "expiresAt": "1741092241", "merchantSessionIdentifier": "SSH88312C485D_7E0DD10173", "nonce": "3f6dc197", "merchantIdentifier": "5F9BC6BAF8", "domainName": "libertybank.ge", "displayName": "Apple Pay Purchase", "signature": "3080060000", "operationalAnalyticsIdentifier": "Apple Pay Purchase:5F9BC6BAF8", "retries": 0, "pspId": "5F9BC6BAF8" } } which is successfully validated applePaySession.completeMerchantValidation(data.sessionData) After this, the "oncancel" handler is triggered in applePay. Please help us to understand what is wrong. Please note the domain where the applepay button is located is at txpg.libertypay.ge Which is successfully verified.

How to correctly calculate sales tax for digital goods (no shipping address) before authorizing transaction
Hi, we are setting up Apple Pay on our website which sells only digital goods. We don't collect a shipping address because we aren't shipping anything. We want to use the user's billing address in order to show them the total amount (including sales tax) before they authorize the purchase. However, it seems that the billing address isn't always provided by Apple Pay before the payment is authorized. With Apple Pay, what is the recommended way of acquiring the user's billing address before they authorize the purchase? -- More details about our setup: We are using the Apple Pay JS API. In createPaymentRequest, we specify requiredBillingContactFields: ['postalAddress'], but per the docs, the address is provided after the user authorizes the transaction. That is too late for us because we want to show the sales tax before the user authorizes the purchase. We have attempted to work around this by getting the billing contact details in session.onpaymentmethodselected. For example: session.onpaymentmethodselected = function (event) { const billingContact = event.paymentMethod.billingContact; // Sometimes `billingContact` exists, but other times it does not } This doc states: Before the user authorizes the transaction, you receive redacted billing contact information in a callback event. The redacted information includes only the necessary data for completing transaction tasks, such as calculating taxes or shipping costs. But in practice, we've observed that sometimes no billing contact information is provided. When a user switches from one card to another, we seem to never get the billing contact associated with the newly selected card. Is there something we're missing?

Pay With Apple Type not found
In the docs, I see a button type with label "Pay With [apple logo]. https://developer.apple.com/design/human-interface-guidelines/apple-pay Although I don't see this type as an option here: https://developer.apple.com/documentation/PassKit/PKPaymentButtonType Wondering if I'm looking in the right place and if this button type is still available?

Continuous "Tag mismatch" (AES-GCM) decrypting Apple Pay Web token - Suspected KDF / PartyV environment issue
I'm implementing payment processing with Apple Pay on the web, but I've been stuck right at the final step of the flow: decrypting the payment data sent by Apple. Here is a summary of my implementation: The backend language is Java. The frontend portal requests the session and performs the payment using the endpoints exposed by the backend. I created .p12 files from the .cer files returned by the Apple Developer portal for both certificates (Merchant Identity and Payment Processing) and I'm using them in my backend. The merchant validation works perfectly; the user is able to request a session and proceed to the payment sheet. However, when the frontend sends the encrypted token back to my sale endpoint, the problem begins. My code consistently fails when trying to decrypt the data (inside the paymentData node) throwing a javax.crypto.AEADBadTagException: Tag mismatch! I can confirm that the certificate used by Apple to encrypt the payment data is the correct one. The hash received from the PKPaymentToken (header.publicKeyHash) object exactly matches the hash generated manually on my side from my .p12 file. In the decryption process, I'm using Bouncy Castle only to calculate the Elliptic Curve (ECC) shared secret. For the final AES-GCM decryption, I am using Java's native provider since I already have the bytes of the shared secret calculated. (Originally, I was doing it entirely with BC, but it failed with the exact same error). We have exhaustively verified our cryptographic implementation: We successfully reconstruct the ephemeralPublicKey and compute the ECDH Shared Secret using our Payment Processing Certificate's private key (prime256v1). We perform the Key Derivation Function (KDF) using id-aes256-GCM, PartyU as Apple, and counter 00000001. For PartyV, we have tried calculating the SHA-256 hash of our exact Merchant ID string. We also extracted the exact ASN.1 hex payload from the certificate's extension OID 1.2.840.113635.100.6.32 and used it as PartyV. We have tried generating brand new CSRs and Processing Certificates via OpenSSL directly from the terminal. Despite having the correct ECDH shared secret (and confirming Apple used our public key via the hash), the AES tag validation always fails.et, the AES tag validation always fails. Given that the math seems correct and the public key hashes match, could there be an environment mismatch (Sandbox vs. Production) or a domain validation issue causing Apple to encrypt the payload with a dummy PartyV or scramble the data altogether? Any guidance on this behavior or the exact PartyV expected in this scenario would be highly appreciated.

System canceled add payment pass - Apple Wallet
Hello All - I'm attempting to enable my companies app to add credit card to Apple Wallet. Part of our app enables customers to generate new virtual cards on demand and I'm attempting to enable the ability to add these cards to the Apple Wallet. Everything seems to be working all the way to the final stage of the process where I get a PKPassKitErrorDomain systemCancelled and I can't seem to find any clues as to why the system is canceling. For context - I have the com.apple.developer.payment-pass-provisioning entitlement. I have both the Wallet and In-App Provisioning capabilities enabled in the App. I have defined a PKAddPaymentPassViewControllerDelegate class that implements both the generateRequest and didFinishAdding methods. I'm leveraging PKAddPaymentPassViewController in SwiftUI by using a UIViewControllerRepresentable implementing class that returns the view controller properly when makeUIViewController is called. I build a PKAddPaymentPassRequest object and ensure that it is properly filled with encryptedPassData, activationData, and ephemeralPublicKey. As a user I'm able to go to the virtual card view, open the instance of PKAddPaymentPassViewController, select the destination for the card, see the Add Card information. I get to the point where the view tells me it's contacting the card issuer and then I get an error message "Could Not Add Card - Try again later or contact your card issuer for more information" with a "Set Up Later" button. I then get the system canceled error. I should mention that I'm able to add these virtual cards manually via the Apple Wallet. The process works similarly but requires me to provided an OTP to conclude the process. This flow works and I have active cards in my wallet. I'm having a very hard time figuring out how to try and debug this issue further. The only error that the system returns is the system canceled notice. Any insight into where I might be missing something or how to debug the issue further would be greatly appreciated. Any thought on how I could debug this further would also be greatly appreciated. Thanks in advance - AYAL

Apple Wallet extension card art requirement
Dears, We are developing an apple wallet extension. In the Non-ui extension, in the getPaymentPassEntry overriden function we have to return an object such as: ``PKIssuerProvisioningExtensionPaymentPassEntry(identifier: identifier, title: label, art: getEntryArt(image: uiImage), addRequestConfiguration: requestConfig)!`` What is not clear are the requirements for this "art" parameter. Somewhere in the FAQ it says that the art has to be an image of 1536 x 969 resolution, <4 MB, squared corners, no chip contacts, and so forth) but we set there images of any size and the extension displays them without any problem. Are those requirements (1536 x 969 resolution, and so on) only for the images that are displayed in the wallet only after the card has been added? In this case, are those images coming from the PNO directly and not coming from the function above which is in the wallet extension? Thanks,

Renewal of merchant Domains fails and redirects to main page without errors
Hello we are trying to renew our certificates. We are trying to extend the dates of verified domains following the docs https://developer.apple.com/documentation/applepayontheweb/maintaining-your-environment#Renew-Your-Domain-Verification and configure our server with https://developer.apple.com/documentation/ApplePayontheWeb/setting-up-your-server We've downloaded the apple-developer-merchantid-domain-association.txt and update it on their respective locations, click 'ok' button but we get redirected to the main page of the information of the merchant, and it shows the domains without the extending period of time. No popup showing what has failed or what could be the reason of this error, we only get a redirection to the main page.

Scan Code like QR to pay by Apple Pay
During checkout at apple.com using a non-supported Apple Pay on the Web browser, apple.com presents a QR like code offering to "Scan Code with iPhone" to pay. The payment continues using Apple Pay on the iPhone after scan. We already offer Apple Pay and Apple Pay on the Web. Is this QR code option available for us for non-supported browsers? Could you point me to the docs to add it? Thank you.

cybersource Payment Gateway not able to decrypt paymenttoken
Cybersource production support has clarified issue as below "On the BAD Case, it seems that the Apple Payload did not contain the "onlinePaymentCryptogram" object within the JSON. The Cryptogram is critical and mandatory. Since the merchant cannot really control this, and since CYBS is just decrypting the payload and uses it, we cannot comment as to why it was missing. The merchant would need to reach out to Apple and/or decrypt the payment themselves locally to check if and why this data was not present, for troubleshooting purposes."
