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?

What is the version policy for the Apple Pay SDK Javascript ? The documentation refers to this link : https://applepay.cdn-apple.com/jsapi/1.latest/apple-pay-sdk.js The future updates will overrride the file on that link ? Is there a way to be notified of any changes ? We are using a previous version named v1 : https://applepay.cdn-apple.com/jsapi/v1/apple-pay-sdk.js What are the risks not using changing to the lastesdt link ? Thank you for your help.

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.

During the development of our 3D game project, we encountered high memory usage requirements. To address this, we enabled Apple’s Extended Virtual Addressing (EVA) and Increased Memory Limit services. We have confirmed that both services were enabled in the developer backend as well as in Xcode, and we also used updated development and distribution certificates when building the app. However, in our validation process, it seems that EVA and Increased Memory Limit are not taking effect — the game still experiences memory overflow and crashes. Could you please advise: The correct steps to properly use Extended Virtual Addressing and Increased Memory Limit; How we can confirm whether these services are functioning as expected?

Hello, I could not find where I can change the sellers name. Why is the first letter always capitalized? Do I have to change it via Developer-Account or App-Development or Payment-Provider?

iOS 16 and earlier On iOS 16 and earlier, Apple Pay on the Web required Safari—and all interactions with the Apple Pay API to come from the parent/top level page. In order to facilitate the Apple Pay button in an HTML inline frame (iframe), there will need to be cross frame communication between the child and parent pages. Cross frame communication should be secure and robust, therefore the use of postMessage for this purpose is recommended. The expectation is for all communication with Apple Pay to occur from the parent page, so the iframe must relay all Apple Pay related events to the parent to handle. Some examples: Apple Pay availability: The parent calls applePayCapabilities, then sends the message of the response to the iframe, which then uses the value to toggle the visibility of the Apple Pay button. Apple Pay session: The iframe receives an onclick() event when the Apple Pay button is clicked and sends the message to the parent (providing details about the transaction). The parent create the payment request to obtain the session validation URL, and eventually receive session credentials and invokes completeMerchantValidation() to prevent the payment sheet. After the payment is authorized by the Payment Service Provider (PSP), the parent either: Redirects the parent page to a payment success page; or Sends a message to the iframe to complete the transaction flow itself. iOS 17 and later On IOS 17 and later, the iframe HTML element should include the allow="payment" attribute, which should facilitate the cross frame communications instead of needing a dedicated JavaScript library. This means all of the Apple Pay code/calls can reside in the iframe page—which is typically a hosted page from a Payment Service Provider (PSP), all the parent page—typically a merchant—has to do is add the attribute mentioned above to the iframe element. Important: Regardless of the iOS version, the PSP/merchant always needs to make sure the parent page domain is the one registered in the Developer portal, and used in the request to generate a merchant session via ApplePaySession.

We are an acquirer/payment provider offering Apple Pay. Our merchants use our hosted checkout to accept payments. After a user pays with Apple Pay on our checkout, the Wallet transaction record shows our checkout domain as the payee. We would like it to display the merchant’s brand/name so users can recognize or contact the merchant. Is there any parameter or configuration that controls what Wallet shows as the payee? For example, can this be set via a specific field/parameter, or is it strictly derived from the Merchant ID’s display name (or other Apple Pay configuration)? What is the correct approach for a PSP/acquirer to have the merchant’s brand shown in Wallet transaction record? Additional detail: The field in question is the merchant/payee name shown in the Apple Wallet receipt—directly under the transaction amount at the top of the receipt, and again beneath the “Total” line.

Hi, For one of my projects, I am using the Web Drop-in component of Adyen PSP on a Salesforce B2B Commerce site. One of the payment methods is Apple Pay. The payment method is rendered, but the Apple Pay button is not clickable. We tried debugging it but could not identify the root cause. Could you advise how this issue can be fixed? 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!

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?

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.

Hello everyone, We're implementing Apple Pay on the web and are already live, processing transactions. However, we've noticed that occasionally the onlinePaymentCryptogram returned in the paymentData contains spaces, causing it to be rejected by acquirers. Has anyone else encountered this issue? Any insights would be greatly appreciated.

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.

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.

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?

Has anyone had any success enabling Apple Pay checkout for a Google Chrome or Firefox users (macOS or PC)? This was rolled out in iOS 18 but Shopify support hasn't been able to help: https://www.theverge.com/2024/6/13/24177851/apple-ios-18-pay-chrome-scanning-code-wwdc-2024 Thanks

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?

Hi Guys, I am having an issue verifying a card when it is pending verification in the Apple Watch Wallet App and the iPhone Wallet. When the user verifies the card in the wallets, they are redirected to verification in my APP. However, the problem is that I don't know which application is calling, whether it is the Apple Watch or the iPhone, because the URL sends me the same serialNumber from the PKPASS. It is impossible to know if the user wants to verify and activate the card on the watch or the iPhone. Because I only receive the following information in the URL: myapp://app-url? passTypeldentifier=paymentpass.com.apple&action =verify&serialNumber=***** The serialNumber is the same from the iPhone Wallet and the Watch Wallet. func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool { let source = options[.sourceApplication] I try to retrieve the source, but it comes back null. It would be the only way to know the originating App. Can someone help me solve this problem?

Hello, We have implemented In-App Verification using both SMS and mobile app options. While SMS functions as expected, selecting the mobile app for verification in the Wallet app does not open our app on the first attempt. Instead, the verification window simply dismisses. However, if I select "Complete Verification" again and choose the mobile app, deep linking works as expected, and our app opens correctly. This issue occurs with any bank card and app I’ve tested in Wallet. Could this be a bug in the Wallet app where deep linking fails on the first attempt but works on the second?
