There's a purchase I make pretty often on a particular site and I'm trying to automate the boring parts with a macOS app. I can pull the merchant session from their ValidateMerchant endpoint. I can see the Apple Pay dialogue appear, then it will disappear with "Payment Not Completed." Is it fundamentally not possible to use someone else's merchant session in your own app? Thanks

How do we get addPaymentPassViewController response for in app verification without calling that function ? Currently we have working in app provisioning but not in app verification. The apple docs say "The process of generating the cryptographic OTP value is the same as for generating activationData for In-App Provisioning.". How is it the same when in in app provisioning we have this button that returns all necessary info and for in app verification there is no clear way of recieving same info.

Currently I have an app which is completely free for all the users, I might have future versions where I will introduce paid version, where I will surely use Apple IAP and Revenue CAT. How should I clarify this to App store? Should I tell only what I am doing today, or also tell what I will do in future and keep Apple IAP in my conversation?

Team, We are currently checking out on Apple Pay using ALL and MRU as currencies. We have authorized the payment via Touch ID; however, we are not receiving the onPaymentAuthorized event. Could you please confirm if Apple Pay supports ALL and MRU currencies? We have confirmed that it works with other currencies. Thank you!

We are developing an app which allows users to generate a HSBC virtual card using Mastercard API and add this card to an apple wallet. Staging test was passed successfully, but we are stuck in a production test phase. T&C is not even visible, 'Card is not added' is popped on a screen before that. User taps “Add to Apple Wallet” → we present PKAddPaymentPassViewController → they tap Next → after a few seconds the flow fails with "Set Up Later" alert.

We are implementing Apple Pay In-App Provisioning in our issuer iOS application and are encountering a HTTP 500 error returned from Apple servers during the provisioning flow. The issue occurs after generating the encrypted payload and attempting to complete the provisioning process. The Apple service responds with 500 Internal Server Error, preventing the card from being added to Wallet. We would appreciate assistance identifying whether this is caused by: • a payload formatting issue, • cryptographic material mismatch, • entitlement / configuration issue, • or a server-side issue. Environment Platform • iOS: 26.3.1 • Device: iPhone 13 mini • Xcode: 26.3.1 Apple Pay configuration • In-App Provisioning entitlement enabled • Issuer app authorized by Apple for provisioning • Payment Network: Mastercard • Token Service Provider (TSP): MDES Testing environment • Production • App distribution method: TestFlight Provisioning Flow Overview Our implementation follows the standard Apple Pay In-App Provisioning flow: 1. User taps Add to Apple Wallet in issuer app. 2. App presents PKAddPaymentPassViewController. 3. App receives: • Apple public certificates • nonce • nonceSignature 4. Issuer backend generates: • encryptedPassData • activationData • ephemeralPublicKey 5. These values are returned to the app. 6. App constructs PKAddPaymentPassRequest. 7. Wallet attempts provisioning. At this point the request fails and Apple servers return HTTP 500. We see this in the system console, with the phone having Wallet debugging profile installed. Checklist – Common Issues Verified Based on the Apple Pay In-App Provisioning demo guidance, we verified the following configuration items. Entitlements • com.apple.developer.payment-pass-provisioning enabled • Apple Pay capability enabled in Xcode • Correct Team ID and bundle configuration App configuration • PKAddPaymentPassViewController used for provisioning • PKAddPaymentPassViewControllerDelegate implemented • generateRequestWithCertificateChain implemented correctly Cryptographic data • encryptedPassData • activationData • ephemeralPublicKey All values are generated by our issuer backend and returned to the app Feedback ID: FB22249031 (In app provisioning error 500)

When accessing https://applepaydemo.apple.com/payment-request-api, the "Approve with Side Button" prompt is displayed, but it does not appear when using our test domain. I implemented the Payment Request API based on the sample source code from the following URL. On an iPhone device, the Apple Pay payment screen is displayed, but the "Approve with Side Button" icon below the amount does not appear, and instead a spinning loading icon is shown continuously. Could you please help identify the cause? ■ Reference URL: https://applepaydemo.apple.com/payment-request-api ■ Changed parameter: "merchantIdentifier": "〇〇.dev" ■ Accessed domain: 〇〇test.com ■ Test device: iPhone 13 iOS: 18.4.1

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/

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?

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 ?

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?

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?

你好，我们6月1日收到比较多的韩国用户反馈购买我们的内购以后，系统会在稍后的几分钟再次多次从用户的卡里扣出相应的款项，但是我们没有办法第一时间反馈给你们，导致很多用户流失，请问我们怎么才能第一时间联系到你们，还有我们怎么才能第一时间知道是你们的系统是否某个功能出了问题，是否也有相应的论坛我们可以第一时间看到你们相关问题的报道，这样我们排查问题就没那么辛苦，感谢

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?

我是一个银行app开发人员，请问怎么将银行名称显示在苹果钱包“选取银行”列表中，实现用户点击跳转银行app进行免输卡号签约绑定，是否有详细接入步骤和文档？

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 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?
