We have finished integrating Apple Pay in our app and our payment processor is requiring us to send the 3dSecure version used for apple pay (2.1,2.2,2.3,etc.). I believe this only applies to mastercard but would appreciate if anyone has run into something similar and what you specified. I have not been able to find anything in Apple's documentation specifying the version that is used.

I have a question regarding the file apple-developer-merchantid-domain-association.txt. I understand that this file is used during API access for Apple Pay Web payments. However, is it necessary for our company to access this file during the payment process? Also, this domain validation file is expected to be placed in the publicly accessible “.well-known” folder on our web server. Is it acceptable for this file to remain readable by third parties on the Internet, including Apple’s servers, without posing any security risks? Since this file is generated during domain registration on the Apple Developer site and is unique to our domain, we believe there should be no security concerns even if accessed by third parties. However, are there any specific security requirements for this domain validation file? Please note that the domain validation has already been successfully completed. We appreciate your time and look forward to your guidance. Best regards,

We are having trouble trying to renew our Apple Pay Merchant Identity Certificate. We can create the CSR file and add to the developer portal. We then convert this to a .pem and then a .p12. When we test the certificate in Postman however, we see the following error: "statusMessage": "Payment Services Exception pspId=xxxx unauthorized to process transactions on behalf of merchantId=xxxx reason=xxxx is not a registered merchant in WWDR and isn't properly authorized via Mass Enablement, either.", "statusCode": "417" We are sending the following POST request to 'https://apple-pay-gateway.apple.com/paymentservices/paymentSession': {"merchantIdentifier": "merchant.com.xxxx.applepaytest", "domainName": "beta-xxxx.com", "displayName": "beta-xxxx.com"} Anyone got any ideas what the issue may be? In the meantime I will look at completing our domain verification as that is also due soon and we thought it may possibly have something to do with the certificate issues we are seeing.

Hi, we are trying to verify our domain and we uploaded the file to our domain {DOMAIN}/.well-known/apple-developer-merchantid-domain-association.txt and we can access it. But when we want verify the domain in your platform we can't do it and you see the message "Domain verification failed". How can we verified or if we need change something in our side to verify it? thanks!

Basic information: The issuer has implemented the feature to active Apple Card via URL Verification. The feature implemented by issuer is supported both in the APP and Clips. When Apple queries the activation method from UnionPay, UnionPay returns the "URL" activation method to Apple. Additionally, the apple-app-site-association file has been correctly deployed, and the configuration for Universal Links has been completed. Both the APP and Clips have undergone testing for Universal Link calls. The desired experiece is that when the APP is installed, Apple Wallet launches the APP, and the user completes the activation within the APP, and if the APP is not installed, Apple Wallet calls Clips, and the user completes the activation in Clips. Problem description: Under iOS 17 and iOS 18, when triggering Apple Pay card activation, the APP or Clips can be called as expected, and the activation can be completed well. However, Under iOS 26, regardless of whether the APP is installed, under the same circumstances, an internal browser within Apple Wallet opens to access the H5 page corresponding to the URL, instead of redirecting to the APP or Clips. Please assist in confirming whether this is a new feature of iOS 26 and how the same user experience can be achieved.

For Apple Pay testing, I have tried the following: Sign into the Sandbox Account via Developer Settings: Settings > Developer > Sandbox Account Keep your main Apple ID for everything else Add Test Cards to Wallet: Try adding the test card numbers (MasterCard and Visa Debit, as we support only those) Apple provides in their documentation. Unfortunately, none of them are added to the wallet. All the time it gives 'Could Not Add Card'. I tried on devices with iOS 18+. Can anyone advise on this? Thanks

We’re attempting to call the Apple Pay Web Merchant Registration API using our Platform Integrator flow and consistently receive 401 Unauthorized, despite successful TLS/mTLS. Details: Endpoint: https://apple-pay-gateway-cert.apple.com/paymentservices/registerMerchant (POST) Payload: { "domainNames": ["breakerfy.com"], "encryptTo": "platformintegrator.ai.packman", "partnerInternalMerchantIdentifier": "merchant.ai.packman.1", "partnerMerchantName": "breakerfy", "merchantUrl": "https://breakerfy.com" } Domain association: URL: https://breakerfy.com/.well-known/apple-developer-merchantid-domain-association What we tried: We created a Payment Platform Integrator ID (platformintegrator.ai.packman) We created a CertificateSigningRequest We used the certificate signing request to create an Apple Pay Platform Integrator Identity Certificate and downloaded the signed certificate. We exported the Private Key from keychain access in PKCS 12 format We converted both the private key and the signed certificate to PEM format We created a merchant id We used the converted keys to send requests to the API We received { "statusMessage": "Payment Services Exception Unauthorized", "statusCode": "401" } we also tried curl with the original p12 file and also had no luck. What could be the issue ?

PLATFORM AND VERSION iOS Development environment: Xcode Version 16.2 (16C5032a), macOS 14.6.1 Run-time configuration: iOS 26 DESCRIPTION OF PROBLEM We would like to seek clarification on how to determine whether a card used via Apple Pay is a credit or debit card before sending the transaction request. Currently, we can retrieve the card type information (credit/debit) from the Apple Pay response payload, but this is only available after the payment has been processed. However, we need to determine the card type in advance, as our system calculates and applies transaction fees based on the card type, which should be added to the total transaction amount before submission. Could you please advise if there is any parameter, API field, or pre-authorization mechanism available to identify the card type prior to initiating the transaction request? We would appreciate your guidance or any related documentation for implementing this. STEPS TO REPRODUCE Initiate Apple pay Payment from Apple pay Getting payload we can retrieve the card type information (credit/debit) from the Apple Pay response payload, but this is only available after the payment has been processed. We need to identify if there's any way to know the card user selected(whether it is credit/debit) before processing the payment.

Hello. What is the process to get my company listed as an approved Apple Pay Payment Service provider here: https://developer.apple.com/apple-pay/payment-platforms/ We are integrating Apple Pay on our gateway. Our customers are merchants who accept ecommerce payments via our payment gateway. We would like to appear on the list here: https://developer.apple.com/apple-pay/payment-platforms/ Thank you.

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.

Hi everyone, I’m encountering a strange issue with Apple Pay in our React Native iOS app using the Stripe React Native SDK. Summary of the Problem: • Apple Pay shows up as an available payment method inside the Stripe Payment Sheet. • When I tap Apple Pay, the Apple Pay sheet opens normally. • After confirming payment, the Apple Pay sheet immediately closes, and nothing happens. • No payment is created and no request reaches Stripe’s servers. On Stripe Dashboard the PaymentIntent remains incomplete, with no errors, which means the failure happens before Stripe receives anything. Environment • React Native with @stripe/stripe-react-native • StripeProvider configured with: <StripeProvider publishableKey={...} merchantIdentifier="merchant.com.app.venga" stripeAccountId={...} urlScheme="venga" > Apple Pay works on our web checkout with the same merchant identifier. We have verified all of the required Apple Pay setup: • Merchant ID exists, active, and matches exactly. • Merchant ID added to the iOS app target in Xcode → Signing & Capabilities. • Apple Pay capability enabled. • Merchant domain is verified (web checkout works). • Apple Pay certificate and merchant certificate are valid. • Stripe publishable key and merchantIdentifier are correct. • Stripe SDK correctly initialized. • Device region supports Apple Pay. Extra Observations: • The PaymentIntent’s allowed_payment_methods includes "card" and Apple Pay does appear in the payment sheet. • But after tapping Pay → the Apple Pay sheet closes instantly. • There is no callback with an error, and nothing appears in Stripe logs. • We are testing in Sweden. As far as I know Apple Pay should work fine here. Questions: What could cause the Apple Pay sheet to dismiss instantly after attempting a payment? Could this be caused by a merchant ID mismatch—even if Apple Pay appears in the sheet? Is there any Apple-device-level requirement (region, wallet config, card type) that could cause this silent failure? Is there a way to get more detailed logs when Apple Pay closes before Stripe receives anything? Any help or suggestions would be greatly appreciated. Thanks!

Hello -- We're preparing to roll out Apple Pay on website in the next week but encountered some issues during testing. While we successfully processed transactions using a VISA card, we ran into errors when testing with other card brands. Has anyone come across this issue before?

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.

Dear Apple Developer Support, I would like to request a technical escalation to the engineering team regarding an ongoing issue with Apple Pay domain verification. Error returned by Apple Even though Apple’s request to our domain returns HTTP 200, the verification still fails with: resultCode: 13014 resultString: "Domain verification failed. Review your TLS Certificate configuration to confirm that the certificate is accessible and a supported TLS Cipher Suite is used." requestUrl: https://developer.apple.com/services-account/QH65B2/account/ios/identifiers/verifyDomain TLS Certificate Validation We performed a full TLS analysis: Certificate issued by Sectigo Public Server Authentication CA DV E36 (public trusted CA) Full and correct certificate chain No handshake errors Configuration fully valid SSL Labs rating: A From our side, the TLS configuration is confirmed to be correct. Accessibility of the .well-known file The file is publicly and accessible It returns 200 OK and the content is exactly identical to the file downloaded from the Apple Developer Portal, without any modification. Our network team confirmed that Apple’s verification request also receives HTTP 200 when pressing “Verify” in the Apple Developer Console. Network-side findings We monitored Apple’s request in real time. Findings: TLS handshake succeeds No cipher mismatch File delivered correctly Status: 200 OK No redirect or transformation applied Despite this, Apple still returns error 13014. Request for engineering review We kindly request that an Apple engineer verify the following: The actual TLS handshake performed by Apple's verification service (cipher suite, protocol negotiation, SNI, trust chain). Whether the Sectigo issuing CA is fully trusted and supported by your domain-verification backend. If there is an internal reason behind error 13014—since the external message does not provide actionable details. Whether the response is rejected for reasons other than TLS, given that the file is accessible and the request returns 200. The exact condition that leads Apple to report “TLS Certificate configuration is incorrect” in this case. This issue is blocking an urgent deployment and must be resolved as soon as possible. Existing case reference Case ID: 102760005987 We are fully available to provide: full response headers packet captures (PCAP) SSL/TLS diagnostics file integrity checks server configuration details or join a technical call (Teams / WebEx) Thank you in advance for the escalation.

Hello I'm getting an error when the Apple Pay sheet opens on a third party browser like Chrome when completeShippingMethodSelection is called 'DataCloneError: Failed to execute 'postMessage' on 'Window': #<Object> could not be cloned.' I'm also seeing this warning when the apple pay sheet opens Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://applepay.cdn-apple.com') does not match the recipient window's origin although I also see this warning on https://applepaydemo.apple.com/

I'm seeking clarification on how Requirement 4.1 ("Card Issuers with a Mobile App must support In-App provisioning") applies when the card issuer uses a third-party mobile banking platform rather than a self-developed app. Our situation: We are a small credit union (the card issuer) Our mobile banking app is provided by a third-party digital banking vendor (white-label, but branded with our name) Card processing is handled by a separate vendor The ambiguity: The Apple Pay Specifications define "Card Issuer Mobile App" as: "The Card Issuer-branded, iOS software application made available on a Device that is used by such Card Issuer's customers to manage, administer, or use Cards." Our mobile banking app meets this definition—it's branded with our name and used by our members to manage their accounts and cards. However, we don't develop or directly control the app; our digital banking vendor does. The webinar FAQ stated: "Do we have to implement in-app provisioning? Yes, if you have an app." Our digital banking vendor interprets this as not applying to them because they are "not the issuer." They've stated: "Apple's requirements are at the card-processor level... our credit unions and, by extension, we are not required to support Apple Pay's in-app provisioning." Our card processor has indicated they will support in-app provisioning integrations but notes "this would be digital provisioning and we would need the digital banking vendor to work with us to enable." Specific questions: When a card issuer uses a third-party mobile banking app (branded for the issuer but developed/maintained by a vendor), does Requirement 4.1 apply? If yes, who bears compliance responsibility—the issuer, the mobile app vendor, or both? If the mobile app vendor does not implement in-app provisioning by January 15, 2026, what is the issuer's exposure? Does the issuer face suspension from the Program due to vendor non-compliance? Is there an alternative compliance path under Requirement 4.8 (Web Provisioning) for issuers whose mobile app vendors cannot deliver in-app provisioning by the deadline? This scenario likely affects hundreds of small financial institutions using shared digital banking platforms. Clarity on vendor vs. issuer responsibility would help the entire ecosystem prepare appropriately. Thank you.

Hello, I'm using PassKit with to perform Apple Pay payment in a financial application. Our approach are: On iOS application, define PKMerchantCapability threeDSecure and credit, perform apple pay experience and get the encrypted response. On PCI service, receive the encrypted data Payment token, decrypt this data, and use to perform the payment. The problem is, in MasterCard transaction the eciIndicator is missing. I want to know if has some rule or problem about it.

Is there a way to allow ApplePay to make deferred payments to a suite of stores, or will each store need the user to initially approve a payment manually?

For Apple Pay Testing purposes, we're trying out cards from https://developer.apple.com/apple-pay/sandbox-testing/ Visa, AMEX, Discover cards can be added to the wallet. But all 5 of the listed options for Mastercard cannot be added to the wallet with the error "Card Device Limit". How can we resolve this?
