I am writing regarding an issue I have encountered while attempting to complete a payment using test users created within the Sandbox environment of Apple Pay. The problem persists specifically when trying to make payments through the demo page at https://applepaydemo.apple.com/. Problem Description: When initiating a payment process with either of the following test user accounts. The flow proceeds as follows: The Apple Pay window appears correctly. Processing begins but does not conclude successfully. After processing concludes, there is no prompt for 'Pay with Touch ID'. Additional Information: Device & OS Version: MacOS 15.3.2 Browser & Version: Safari 18.3.1 Real Device or Simulator: Real device used First Occurrence: Before January 1st, 2025 Custom Configurations or Backend Used: No custom configurations or backend modifications are being utilized during interaction with the demo page. Could you please provide assistance in resolving this issue?

Hi Team, when launching an ApplePay session from a 3rd party browser where we get the QR code popup - is it possible to affect the popup's language? We are setting the button's language via locale parameter, but when the QR code pop's up it does not respect this setting (seems like it respects browser language). Button in Arabic Corresponding popup Browser language Arabic Coresponding popup I was unable to find anything in the documentation - could you please either point me to the relevant documentation or confirm/deny that it is possible to request a language for the popup via tjr javascript API? Kind regards Tomas

I'm implementing Apple Pay in a Flutter iOS app using the pay plugin and Braintree as the payment processor. I have followed all necessary steps as outlined by Apple and community resources (e.g., Medium articles, official Apple Developer documentation), but the Apple Pay button does not appear on a real device. Here's what I've completed: Created an Apple Pay Merchant ID Created and downloaded the Apple Pay Payment Processing Certificate, then uploaded it to Braintree Downloaded the Braintree-signed certificate and confirmed it's active in the Apple Developer portal Added the Merchant ID under Signing & Capabilities in Xcode Enabled Apple Pay capability in Xcode Added the Merchant ID to Info.plist Installed required Flutter packages (e.g., pay) Using a valid Apple Pay payment configuration file in Flutter (see below) Tested on a real iOS device with a valid Apple Pay test card added to Wallet Flutter Payment Configuration (in Dart JSON): json Copy Edit { "provider": "apple_pay", "data": { "merchantIdentifier": "merchant.com.example", "displayName": "My Store", "merchantCapabilities": ["3DS", "debit", "credit"], "supportedNetworks": ["visa", "masterCard", "amex"], "countryCode": "US", "currencyCode": "USD" } } Despite this complete setup, the ApplePayButton widget remains invisible There are no errors in the console. Can you help identify what may be missing or misconfigured at the code or configuration level?

Hello everyone, I’m currently in the process of implementing Apple Pay on my company’s e-commerce website under a subscription model with recurring payments. I would appreciate some help in clarifying the following points: Is the applicationPrimaryAccountNumber the DPAN and the merchantTokenIdentifier the MPAN? If not, which fields represent each one or how do I recognise them? Is the onlinePaymentCryptogram used only for processing payments with the DPAN, or is it also involved when using the MPAN? Is the onlinePaymentCryptogram single-use or does it have an expiration time? Or is it reusable with no limits? According to Apple’s data policies, is it recommended for our servers to perform the payment token decryption (debundling), or should this only be handled by the payment gateway processor to stay compliant? Below is the payment request I’m using for testing, along with the decrypted payment token returned for a test card: Payment Request: { "countryCode": "US", "currencyCode": "USD", "merchantCapabilities": ["supports3DS", "supportsDebit", "supportsCredit"], "supportedNetworks": ["visa", "masterCard", "amex", "discover"], "requiredBillingContactFields": ["postalAddress", "name"], "lineItems": [ { "label": "Subtotal", "amount": "9" }, { "label": "Taxes", "amount": "1" } ], "total": { "label": "Demo (Card is not charged)", "amount": "10", "type": "final", "recurringPaymentIntervalUnit": "month" }, "recurringPaymentRequest": { "paymentDescription": "Recurring payment", "regularBilling": { "label": "Demo (Card is not charged)", "amount": "10", "type": "final", "paymentTiming": "recurring", "recurringPaymentIntervalUnit": "month" }, "managementURL": "${window.location.origin}/api/managePaymentMethod" } } Decrypted Payment Token: { "applicationPrimaryAccountNumber": "5204240494898922", "applicationExpirationDate": "280630", "currencyCode": "840", "transactionAmount": 0, "deviceManufacturerIdentifier": "050110030273", "paymentDataType": "3DSecure", "paymentData": { "onlinePaymentCryptogram": "MCt5xR+VnQAAAAM/8mUjAAADFIA=" }, "merchantTokenIdentifier": "DM4MMC1US000000042e438d170774669844e732a41c28e97", "merchantTokenMetadata": { "cardMetadata": { "longDescription": "Test Bank for MasterCard MTF", "cardCountry": "US", "shortDescription": "Test Bank 2", "fpanSuffix": "0049" }, "cardArt": [ { "url": "https://nc-crt-smp-device-asset.apple.com:443/broker/v1/assets/174ce63257704d93b00aff8aa09ec0d5", "name": "cardBackgroundCombined@2x.png", "type": "image/png" } ] } } Thanks in advance for your help and guidance.

Apple Sandbox is not available in India, also Apple Pay itself is not supported by Indian Banks. How can I still test using Apple Pay sandbox in India? I am trying to add test cards on my iPhone and it fails to add it. It tries to connect to Issuer, which it should not for sandbox Apple Id. Can anyone help how to achieve this?

I'm currently integrating Apple Pay with my payment provider, and I'm encountering a signature validation error during the payment flow. Here's the setup: I’ve verified that my Merchant Certificate is valid, and I'm able to initialize the Apple Pay session without any issues. Also this curl works fine The Payment Processing Certificate was created by my PSP. PSP claims that the payment token signature is invalid during the transaction phase, which prevents payment completion. The parsed signature starts like this 0:d=0 hl=2 l=inf cons: SEQUENCE 2:d=1 hl=2 l= 9 prim: OBJECT :pkcs7-signedData 13:d=1 hl=2 l=inf cons: cont [ 0 ] 15:d=2 hl=2 l=inf cons: SEQUENCE 17:d=3 hl=2 l= 1 prim: INTEGER :01 20:d=3 hl=2 l= 13 cons: SET 22:d=4 hl=2 l= 11 cons: SEQUENCE 24:d=5 hl=2 l= 9 prim: OBJECT :sha256 35:d=3 hl=2 l=inf cons: SEQUENCE 37:d=4 hl=2 l= 9 prim: OBJECT :pkcs7-data 48:d=4 hl=2 l= 0 prim: EOC 50:d=3 hl=2 l=inf cons: cont [ 0 ] 52:d=4 hl=4 l= 995 cons: SEQUENCE 56:d=5 hl=4 l= 904 cons: SEQUENCE 60:d=6 hl=2 l= 3 cons: cont [ 0 ] 62:d=7 hl=2 l= 1 prim: INTEGER :02 65:d=6 hl=2 l= 8 prim: INTEGER :16634C8B0E305717 75:d=6 hl=2 l= 10 cons: SEQUENCE 77:d=7 hl=2 l= 8 prim: OBJECT :ecdsa-with-SHA256 87:d=6 hl=2 l= 122 cons: SEQUENCE 89:d=7 hl=2 l= 46 cons: SET 91:d=8 hl=2 l= 44 cons: SEQUENCE 93:d=9 hl=2 l= 3 prim: OBJECT :commonName 98:d=9 hl=2 l= 37 prim: UTF8STRING :Apple Application Integration CA - G3 I'm looking for guidance on what could be causing this signature failure. Does anyone know what else I can check regarding the merchant or payment processing certificates, private keys, or key usage that might cause Apple Pay signature validation to fail, even if the session initializes successfully? Domains are also verified. Any help or suggestions would be greatly appreciated.

What am I missing in my checking for whether or not to offer Apple Pay on my website? <script async crossorigin src="https://applepay.cdn-apple.com/jsapi/v1.1.0/apple-pay-sdk.js" ></script> ... <style> apple-pay-button { display: none; } </style> ... <apple-pay-button buttonstyle="black" type="plain" locale="en-US" onclick="startApplePay('${APPLE_PAY_MERCHANT_ID}','${paymentForm.amount}');"></apple-pay-button> So, the button is not displayed by default. I only change the style to displayed if: window.onload = function() { if (isApplePaySupported()) { document.querySelector("apple-pay-button").style.display = "inline-block"; }; } function isApplePaySupported() { return (window.PaymentRequest && window.ApplePaySession && ApplePaySession.canMakePayments() && ApplePaySession.supportsVersion(applePayVersion)); } Yet, once in a while a click comes through that tries to create a PaymentRequest with const applePayMethod = { "supportedMethods": "https://apple.com/apple-pay", "data": { "version": applePayVersion, "merchantIdentifier": merchantIdentifier, "merchantCapabilities": [ "supports3DS" ], "supportedNetworks": [ "amex", "discover", "masterCard", "visa" ], "countryCode": "US" } }; and results in: NotSupportedError, The payment method is not supported What else might be "not supported" in the request for this particular user/device/wallet? In particular, that could be known immediately when the PaymentRequest is created, but before any payment instrument from the wallet is selected? And, is there anything I could detect before showing the button? Or, is it even possible for the button to be clicked by some kind of automation, even if it's not displayed?

I built a web application using the Apple Pay on the Web Interactive Demo with the Payment Request API, but encountered a few issues: The initiated web Apple Pay interface shows a spinning circle at the bottom and cannot proceed with payment（Bottom display:正在处理）. What could be causing this? How to set up sandbox testing for payments? How to asynchronously and synchronously retrieve payment results (backend code to fetch payment results)? The demo only shows frontend code using await response.complete("success"); for retrieving payment results my demo URL： https://shop.wowseer.com/rsolomakhin/pr/applepay/

我使用Apple Pay on the Web Interactive Demo构建了一个web应用使用的是Payment Request API方式，但是遇到了几个问题： 拉起的web Apple Pay 底部一直转圈圈无法付款，这个是什么问题？ 如何设置sandbox测试付款呢？ 如何异步、同步获取支付结果（后端代码获取支付结果）？demo只有await response.complete("success");前端代码获取支付结果的操作 demo网址: https://shop.wowseer.com/rsolomakhin/pr/applepay/

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!

I am facing an issue with Apple Pay js while doing the integration we are using reference https://applepaydemo.apple.com/apple-pay-js-api In this I can generate the merchantSession correctly But when I pass that merchantSession in session.completeMerchantValidation(merchantValidation) as per documentation It is getting failed and also no appropriate error is being shown in the console

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/

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.

We are on a .NET ecommerce site hosted on AWS on a windows 2012R2 server. We have apple pay for the web integrated on the site and the certificates (merchant id and apple pay) were set to expire shortly. We created a new merchant id and apple pay cert, however we are now stuck as the new merchant ID certificate doesn't appear to be working although the old one did. Note there have been no code changes. Basically the apple pay process is failing on the merchant validation. Here are the steps we took: Created a CSR in Keychain Access Generated a Merchant ID cert in the Apple Developer account with that CSR. Imported the Merchant ID cert back into Keychain Access and exported as a p12 file the cert and the private key used to generate the CSR. Imported the p12 file into Windows 2012 R2. I can see in our debugging that the new certificate is being loaded but a SSL/TSL connection couldn't be made. So it seems there is an issue with the cert. Has anyone encountered this? I'm out of ideas at this point and under a lot of pressure from management to fix what was supposed to be a routine maintenance issue. If anyone has any ideas, that would be greatly appreciated.

Dear Apple team and developers, We integrated Apple Pay E-Commerce on our system and made successful transaction at January using following certificates. Merchant Identity Certificate (generated from our Apple developer account) Payment Processing Certificate (generated from our Apple developer account) Payment Session Server Certificate (used following command and generated from apple-pay-gateway-cert.apple.com:443 test URL) Command: openssl s_client -connect apple-pay-gateway-cert.apple.com:443 -key MIC_priv.key -cert MIC_merchant_id.pem -showcerts | openssl x509 -outform DER &gt; apay_ident_trusted_cert_test.der Root CA G3 (Downloaded “Apple Root CA – G3 Root” from https://www.apple.com/certificateauthority/ ) But at this month, we got new certificate problem (please check following) when we try to execute Apple Pay E-Commerce transaction. Certificate 'C=US,O=Apple Inc.,OU=Apple Certification Authority,CN=Apple Application Integration CA - G3' is not valid Certificate. What is this certificate? And Where can I download or generate this certificate from? Could you please advise/give us good information for this certificate problem? Best Regards, Bilguun Enkhbaatar

Hi All, We operate a store with a single domain but multiple merchants, some of whom use PayPal as their payment gateway, while others use Stripe. We are looking to introduce Apple Pay for the various merchants. From what I understand, a .well-known file is required for each merchant to enable Apple Pay. How can we implement this, given that our merchants are using different payment gateways? Best regards, Joe

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.
