we are currently using the requestAutomaticPassPresentationSuppression API in my app. to prevent the Wallet interface from appearing when an NFC/RF reader is detected during active app usage. Recently, a new transit card supporting Express Mode (T-money Transit Card) was released in Korea, and we are seeing an increasing number of users enabling Express Mode. However, this has introduced an issue where users are unable to use the BLE-based functionality we provide via our widget. Specifically, when the user taps our widget, it triggers a BLE signal broadcast for approximately 10 seconds. In this scenario, when the user brings their iPhone close to our reader, Express Mode is activated before the BLE interaction can be established. This prevents the BLE signal from being successfully received and processed. We would like to ask: Is it possible to suppress Express Mode behavior (similar to requestAutomaticPassPresentationSuppression) even when the app is launched via a widget interaction? Alternatively, is there any way to delay or defer Express Mode activation temporarily when launching from a widget or during BLE communication? We would appreciate any guidance or best practices you can share regarding this scenario. Thank you.

Hello, We are experiencing an issue with Apple Pay integration in our application. We are using WKWebView to handle various payment methods, but we are unable to complete payments via Apple Pay. Upon debugging the WKWebView, we received the following error message: "400 No required SSL certificate was sent" when attempting to process the payment. Currently, we are using a Let's Encrypt SSL certificate. Could you please confirm whether this certificate is suitable for Apple Pay, or if we should be using a different SSL certificate?

Hello, I have recently started exploring the Apple Wallet extension and have a couple of questions I was hoping you could help clarify: Is there any form of communication between the UI extension and the non-UI extension? From my understanding, the UI extension handles the authorization and simply indicates whether the app approves it or not, without passing additional data. However, the non-UI extension is expected to make calls to the issuer app’s backend, which typically require a token obtained through prior authentication services and may even involve an OTP. Is there a recommended way to share this information between extensions within the Apple Wallet Extension framework, or is using App Groups the only option? Additionally, during the provisioning process, is there any possibility of re-invoking the UI extension if further validation is required? Furthermore, according to the documentation, testing is carried out via TestFlight and in production. Is there any way to test these extensions on a physical device directly from Xcode for debugging purposes, or is TestFlight the only available method? Thank you very much in advance for your time and assistance.

To perform the integration, it must be done under the same domain that has been validated. Is it not possible to do it in a local environment? Could that be the reason why I can't display the button or complete the validation with the API?

Hi, I’ve been trying to integrate Apple Pay, but for some reason, the payment button is not showing up. The project is built with Laravel 11 and Vue. I imported the script as follows: <script crossorigin crossorigin src="https://applepay.cdn-apple.com/jsapi/1.latest/apple-pay-sdk.js" ></script> Then I added the following the steps: <style> apple-pay-button {{ --apple-pay-button-width: --apple-pay-button-width: 150px;; --apple-pay-button-height: --apple-pay-button-height: 30px;; --apple-pay-button-border-radius: --apple-pay-button-border-radius: 3px;; --apple-pay-button-padding: --apple-pay-button-padding: 0px 0px;; --apple-pay-button-box-sizing: border-box; } </style> <apple-pay-button buttonstyle="black" type="plain" locale="en-US"></apple-pay-button> I followed all the steps from the official Apple Pay demo: https://applepaydemo.apple.com/ I also configured the Content Security Policy (CSP) to allow all necessary resources. However, when I test my integration, the button doesn’t appear. I’ve checked the console, but there are no errors. At the same time, I have my certificate imported into the Keychain, and I’ve completed the entire process of creating both the certificate and the private key. However, when I try to validate the session using the certificate and key with Apple’s API, I get an error: 400 The SSL certificate error https://apple-pay-gateway-cert.apple.com/paymentservices/

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?

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?

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 plan to set Manual PAN Entry Allowed = N and accept only issuer push provisioning (PKAddPaymentPass). Is there any Apple Pay programme rule that obliges us to keep MANUAL_ENTRY enabled? Will disabling it affect “Participating Issuer” listing?

We have verified our domain but if the file is removed from the deployed site after verification will this impact using ApplePaySession.applePayCapabilities in real time? We use that method from the JS api in our React app to determine whether or not to show the apple pay button. When that function is called in the browser, do the apple servers ping the https://our.domain.com/.well-known/apple-developer-merchantid-domain-association URL at that time? Or do they check for it periodically? The reason for asking is that with our many environments we wonder if we can verify each environment's domain by adding the file once. The file will be wiped out by our CICD process as it goes up the environment stack through our development workflow. Or do we need to maintain that file for each environment and add something to our build process?

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.

I am trying to play around on the Apple Pay demo page (https://applepaydemo.apple.com) and I am getting the following error response. PaymentRequest AbortError: The operation was aborted. I am using the Payment Request API

Hello! We use Apple's "master account" scheme to register new clients trough API due to the fact that the number of merchant IDs in a developer account cannot exceed 100 records. It's been almost a year since we successfully used the master account ( ex. "merchant.com.xxx") and register clients via Postman. At the moment, the certificates for the master merchant ID start to expire on July 11 which will affect all customers which is under Master ID. We know that when updating certificates at the identifier level(our master id), new universal identity certificate files that we use to send to the merchants (merchant_id.pem, privkey.key) will be generated for authentication on the merchant side, as well as a new keystore. Since many of our clients are integrated with current files and keystores and have live traffic, we would like to know—is it possible to update certificates on the master account without changing the keystores and certificate identities? The impossibility of this will entail a large gap when switching to new certificates. Thanks in advance for your answer.

Hello, We are experiencing a consistent delay when initiating Apple Pay sessions using the https://apple-pay-gateway.apple.com/paymentservices/startSession endpoint. Below is a detailed overview of our setup and the issue. Setup Our web service is hosted in AWS and there is a proxy server between our web service and Apple servers. We are passing the correct domain in the initiativeContext field of the startSession request. The .well-known/apple-developer-merchantid-domain-association file is hosted on a different domain, which is also correctly configured and associated with our merchant ID in the Apple Developer portal. Observed Behavior When the same request is made from a local development environment, Apple responds immediately (under 1 second). When the request is made from our AWS-hosted service, Apple responds with a valid session, but only after a consistent ~15-second delay. The content and response are otherwise identical — only the timing differs. We would appreciate any insights or suggestions from others who have faced similar behavior or from the Apple Pay team. Thank you in advance!

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.

Hi Support, When the applepay express transit option is used on emv payment cards, like this iPhone - Open “Settings” → “Wallet & Apple Pay” → “Express Transit Card”. And a emv single card has been enabled under Express Transit And on transit reader Apple Enhanced contactless Polling support is provided, ( with VAS not supported, user authentciation not supported) Sometimes ATQB response also comes from the iPhone or iWatch instead of the ATQA response, and then it causes the transit reader to report as collision error in the polling. Sequence of the packets: WUPA WUPB ECP frame WUPA WUPB ATQB WUPA ATQA

We are working with Saferpay. And integrating Applepay Server to Server. But we are having token generation issue. It does not give a valid test card information. We have created a tester account as India country. Is that an issue?

I have the HCE entitlements, but it's not clear from the documentation I have, how to configure my app as the default app for the double tap of the power button. Nor can i see where this is in iOS 18.2 settings. The closest I can find is 'Settings > Default Apps > Contactless App', which still shows only Wallet after I install my app with all the new entitlements and provisioning profile. I have these entitlement successfully provisioning my app: <key>com.apple.developer.nfc.hce</key> <true/> <key>com.apple.developer.nfc.hce.iso7816.select-identifier-prefixes</key> <array> <string>A0000000031010</string> <string>A00000002501</string> <string>A0000000049999</string> <string>A0000000041010</string> </array> <key>com.apple.developer.nfc.hce.default-contactless-app</key> <true/> The documentation here: https://developer.apple.com/support/hce-transactions-in-apps/ also references a link to changes in Info.plist, but the url takes me to storekit-external-entitlement documentation about dating apps in the netherlands ???!!!??? Any help would be appreciated to at least get started by allowing me to change the double tap action to my app. Thanks

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.

We are unable to add/remove Merchant IDs in App IDs identifier profile, after pressing "Edit" button on "Apple Pay Payment Processing" section, then choosing desired Merchant ID to check/uncheck from the available Merchant IDs, then pressing Continue/Save/Confirm buttons - nothing happens, the "Save" button text briefly changes to "Processing" and then back To "Save" and we still have previously enabled Merchant IDs and the Save button is still in enabled state, any help?
