I developed a web app using .net c#. The app runs a workflow which included Apple payment. App can work on any browser of any device (even non-IOS). When the app is browsed using PC windows Chrome browser, the payment sheet will show with QR code to scan using iPhone. If I cancelled the pop-up by clicking on X without scanning the code, and then returned to idle screen and performed another payment, I will reach paymentRequest.Show() but nothing will show and no errors are logged in console. Note that: I use Payment Request API The issue appear on the second payment. The issue will be solved once I refresh the page. My app supports both single and separate pages mode and issue appear on both. I used to see an error "Uncaught NotSupportedError: Failed to execute 'define' on 'CustomElementRegistry': the name apple spinner has already been used with this registry. So I thought the issue might be in loading the apple SDK script multiple times, and solved the issue to be loaded only once. The error disappeared but the issue persist without errors.

I am encountering an issue with the in-app provisioning flow using PKAddPaymentPassViewController. Specifically, when presenting the controller to allow users to add a pass to Apple Wallet, the device selection screen is showing all the devices, even after setting the primaryAccountIdentifier on the PKAddPaymentPassRequestConfiguration. Here's the context: I'm using PKAddPaymentPassViewController for in-app provisioning. I provide a valid primaryAccountIdentifier in the configuration. But after adding the pass, if i print back the primaryAccountIdentifier it displays some other value different than the identifier i had set(Example masked identifier: FAPLMC1GB000000066aa4xxxxxxxxxxxa744f16axxxxxxxx). The provisioning flow works, but the device list shown to the user includes all the devices (e.g., Apple Watches and iPhone even though it is already added to Apple Watch or iPhone).

Recently, we completed a merger with our parent company. We are currently integrated with Apple Pay in accordance with the “Apple Pay Payment Processing on the Web” guidelines. Due to the change in the legal entity, we proceeded with the account migration process as outlined below: Creation of a new Apple Developer account and a new Apple Pay Identifier Removal of the Merchant Domain (dc2-web.happy.co.kr) from the existing Identifier Registration of the Merchant Domain (dc2-web.happy.co.kr) under the new Identifier Using the Merchant Domain registered under the new Identifier and the Apple Pay Merchant Identity Certificate issued from the new Identifier, we attempted to obtain an Apple Pay session by sending requests to the following endpoint: https://apple-pay-gateway.apple.com/paymentservices/startSession However, we are intermittently receiving failure responses with an HTTP 400 status code. With regard to these intermittent failures, we would like to inquire whether there is any propagation delay on Apple’s servers when an Apple Pay Identifier is removed and re-registered under a new account, or if there could be any other possible causes for this behavior. We would appreciate your guidance on this matter.

We have used the ApplePayRecurringRequest parameter required for Apple Pay subscriptions, but during testing the payment, the Apple Pay payment page shown to the user remains the same as the one-time payment page, without any subscription information. Could you please check if there is an issue with our parameters or if there is an issue with the merchantIdentifier being used? Here is the ApplePayRequestData that we are using. { "supportedMethods": "https://apple.com/apple-pay", "data": { "version": 3, "merchantIdentifier": "***", "merchantCapabilities": [ "supports3DS", "supportsCredit", "supportsDebit" ], "supportedNetworks": [ "visa", "masterCard" ], "countryCode": "US", "recurringPaymentRequest": { "paymentDescription": "A description of the recurring payment to display to the user in the payment sheet.", "regularBilling": { "label": "Recurring", "amount": "4.99", "paymentTiming": "recurring", "recurringPaymentStartDate": "2025-06-02T16:00:00.000Z" }, "trialBilling": { "label": "7 Day Trial", "amount": "0.00", "paymentTiming": "recurring", "recurringPaymentEndDate": "2025-06-02T16:00:00.000Z" }, "billingAgreement": "A localized billing agreement displayed to the user in the payment sheet prior to the payment authorization.", "managementURL": "https://applepaydemo.apple.com", "tokenNotificationURL": "https://applepaydemo.apple.com" }, "additionalLineItems": [ { "label": "7 Day Trial", "amount": "0.00", "paymentTiming": "recurring", "recurringPaymentEndDate": "2025-06-02T16:00:00.000Z" }, { "label": "Recurring", "amount": "4.99", "paymentTiming": "recurring", "recurringPaymentStartDate": "2025-06-02T16:00:00.000Z" } ] }

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?

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.

Hello, we are trying to extend the dates of verified domains following the docs of https://developer.apple.com/documentation/applepayontheweb/maintaining-your-environment#Renew-Your-Domain-Verification and configured the server following https://developer.apple.com/documentation/ApplePayontheWeb/setting-up-your-server we've download the apple-developer-merchantid-domain-association.txt and update them on their respective locations, click 'ok' button and we get redirected to the main page of the merchant certificate, but the expiration dates have not been extended, we can see on our web crawler that Apple Requested the file and it return a 200. No popup errors are shown, no console developer error we only get redirected to the merchant certificate information page.

Hello, I'm experiencing an irregular issue with Apple Pay merchant domain verification. As you know, Apple requires domain verification every two months to maintain Apple Pay functionality. The problem is that while the verification sometimes happens automatically without any issues, other times it fails to complete, even though the required file "apple-developer-merchantid-domain-association.txt" is correctly available on our server. When automatic verification fails, the Apple Pay service becomes non-functional on our website, forcing us to perform a manual verification to restore the pending service. Is it normal to encounter such inconsistent automatic verification processes? What could be causing these intermittent verification failures, whereas manual verification always succeed? suggesting this might not be related to IP address restrictions described on the Apple documentation. Thank you in advance,

Hello, On my website, I have a button to make a payment via Apple Pay. When I click on it, the Touch ID window opens correctly. However, when I place my finger on the Touch ID, I get a payment error. This issue only occurs in production mode. In sandbox mode, everything works perfectly. Here is a log file : log.txt Thank you in advance for your help.

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!

A team observed lots of timeouts from the Apple Pay session endpoint: https://apple-pay-gateway-cert.apple.com/paymentservices/paymentSession Is it expected or some kind of an implementation issue from the caller side? Thanks!

Hi, I'm developer in fintech company, we have setup process for onboarding merchants for our partner and processing payments with usage of Apple Pay API. Daily system is processing ca. 10k payments but every day ca. 100 of transactions are declined because of merchant validation error: request to https://apple-pay-gateway.apple.com/paymentservices/paymentSession (with all required parameters in body) is returning response with status code 417 "statusMessage": "Payment Services Exception merchantId={root merchant id} unauthorized to process transactions on behalf of merchantId={merchant id hash} reason={merchant id hash} is not a registered merchant in WWDR and isn't properly authorized via Mass Enablement, either." Issue impacts recurring merchants, most of their transactions are processed successfully but randomly some of them are failing with such reason. All prerequisites are met: merchant have deployed 'apple-developer-merchantid-domain-association' certificate, certificates are valid and not expired. Apple Support is not able to provide any information based on provided requests timestamps. We would to know what may be the reason just part of the requests are failing and what 417 error code means.

We are developing a native iOS financial application called Tradu: Stocks, Forex, and CFDs (Apple ID: 6473443264), which embeds a WKWebView to render all user-facing logic. All user interactions—including authentication with MFA—occur inside this WKWebView. To access native functionality, we use postMessage() to communicate between the web and native layers. This approach has worked successfully for biometric authentication, for example. We are currently integrating Apple Pay In-App Provisioning and have a few questions regarding compliance with the documentation provided by our Issuer Host (Modulr). In the document titled Getting Started with Apple Pay: In-App Provisioning, Verification, Security, and Wallet Extensions (Version 4.0, February 2023), all examples are based on a fully native application. We’ve managed to integrate most of the In-App Provisioning flow via postMessage() up to the point of passing encryptedData to the Payment View. Apple Pay button inside WKWebView In Section 7: Frontend Overview, the user initiates the provisioning by tapping a native PKPaymentButton (SwiftUI example). In our case, this button is rendered inside the WKWebView, styled according to the Apple Style Guide. While the document references this approach as a “raw mark text supplement,” is this method acceptable and compliant with Apple’s UX and technical guidelines? MFA requirement before provisioning In Section 4: Security Guidelines, it is stated that the user must have passed MFA at least once before starting the provisioning flow. In our implementation, users must complete MFA on every login (including on recognized devices) before the provisioning UI becomes available. Even though this is not tied specifically to “unrecognized devices,” is our MFA requirement sufficient to satisfy Section 4.2? Summary: Is using a web-rendered Apple Pay button inside WKWebView (instead of a native PKPaymentButton) considered compliant? Is our MFA enforcement model (required on every login) aligned with the security requirements outlined in Section 4.2 of the Apple Pay In-App Provisioning documentation?

So we are developing an NFC reader for a client and one of the requirements was Apple ECP. We submitted a product plan and it was approved and we were given access to the specific documentation for ECP. We are looking to only use Loyalty passes via NFC. Not Apple Pay. We wish to develop passes that have NFC capability and apparently you need another approval for NFC Entitlement. Apple just denied our application. No reason given, just denied. How are we suppose to develop a solution when we can only do one side of the development? Also we are seeing VAS mentioned and believe we also need access to this documentation as well, but no idea where to request it. Nothing in our developer portal or wpc portal. Can someone from Apple please steer us in the right direction. As we understand it we need: Approved hardware product plan (which we have) Access to ECP 2.0 documentation (which we have) Access to VAS protocol documentation (we don't have) NFC entitlement to be able to create NFC enabled passes. Let me know what we need to do or if I am not understanding things correctly. Thanks

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?

Two subscriptions, Plus and Max, are under the same subscription group, with Max having a higher tier than Plus. Promotional Offers for Max are configured in Apple Store Connect. When a user subscribes to Plus and then upgrades to Max using Promotional Offers, they are prompted with "Upgrade upon expiration" (Figure 1); if they don't use Promotional Offers, they are prompted to "Upgrade immediately" (Figure 2). Question 1: What is the situation with the "upgrade upon expiration" message in Figure 1? Is upgrading using Promotional Offers special? I couldn't find any relevant explanation in Apple's technical documentation. Question 2: Figure 1 shows an "upgrade upon expiration," but after subscribing, the webhook still shows the subscription start time as the current time, meaning the upgrade hasn't started immediately. Is the message incorrect?

Hi, I am the developer of this app and I was shared this receipt which strangely does not list my name as the merchant but instead says "The flow network" as you can see below: What is going on?

We are attempting to integrate the Apple Pay service into our website and have successfully verified our domain with Apple manually. However, we consistently receive an 'ApplePay reverify failed' email a month before the expiration time. Upon checking, we updated the SSL certificate for the domain before receiving the email, and the link still works fine in the browser. We would greatly appreciate any feedback from someone who can help us with this issue.

Hello Apple Devs, We’re currently trying to integrate Apple Pay on the web using Apple Pay JS. We've followed the official documentation closely, but we're running into a blocker during the merchantSession validation phase. We successfully retrieved a merchantSession, which looks like this: json { "displayName": "Our Name", "domainName": "https://pay.ourdomain.co", "epochTimestamp": , "expiresAt": ****************, "merchantIdentifier": "", "merchantSessionIdentifier": ", "nonce": "", "operationalAnalyticsIdentifier": our name "t:", "pspId": "", "retries": 0, "signature": "*****************..." } Issue: Shortly after initiating the session, we receive a cancel event with the following info: ApplePayCancelEvent { type: "cancel", sessionError: { code: "unknown", info: {} } } We're unsure what causes the cancellation. There are no clear error messages or hints in the logs to identify what went wrong. What We’ve Checked: The merchantSession is returned successfully from our backend. The domainName matches our frontend domain (https://pay.durdomain.co). The session hasn’t expired when tested. We're using Apple Pay JS APIs as described in the documentation. Help Needed: What can trigger an ApplePayCancelEvent with an "unknown" error code? Any insight or guidance would be deeply appreciated. Thanks in advance!

We have developed Apple Wallet Extension for our App. The in-app provisioning for the card is working. However when we try to add the card from Wallet extension it gives error saying "Your issuer does not yet offer support for this card".
