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.

Hello, I', are trying to add applepay payment on our website using the PSP payxpert. They don't provide any SDK to my knowledge unlike paypal/stripe and their documentation just tell to send a few different data as usual credit card payment. But I'm stuck even before that step, we were able to add the applepay button on the site, we did setup the sandbox account on the iPhone with a test card. We could add the merchant id, created the "Apple Pay Payment Processing Certificate", the "Apple Pay Merchant Identity Certificate" and we verified the marchant domain. We have our backend request the validationURL on onvalidatemerchant. We're using PHP, and send the data in json as the example in: https://developer.apple.com/documentation/ApplePayontheWeb/requesting-an-apple-pay-payment-session The validation url we receive from applepaysession js is: https://apple-pay-gateway-cert.apple.com/paymentservices/startSession The doc mentions to add /paymentSession so I tried that as well as just the raw validationURL. Both sends me a 401 Unauthorized response. I'm not sure what missing, I double checked the merchantIdentifier matches and that the initiativeContext is correct, but no luck. I wonder if we missed a step in the configuring the server, as it say to create certificate and upload them. Then we can download the .cer files, do we need to do something with that? Kind regards

Hi! We recently signed up and activated the Web Merchant Registration API and registered a few of our merchants. We registered them as: { "domainNames" : ["X"], "partnerMerchantName" : "Name", "partnerInternalMerchantIdentifier": "MID-###", "encryptTo" : "platformintegrator.X", "merchantUrl": "https://www.x" } When we make the payment with startsession, we are getting an error 400: Payment Services Exception merchantId=platformintegrator.x not registered for domain=x I suspect that this has to do with the value of merchantIdentifier we are setting in the startsession. What should it be? MID-###? The encryptTo hash of platform? platformintegrator.x? Also, what's the meaning of the property on the sub-merchant I get from the GET API call delegatedCommerce: {enabled=True}?

We are currently supporting an Apple Pay-enabled card program as an issuer/issuer processor and have successfully completed In-App Push Provisioning integration within our iOS application. The in-app flow is fully operational, including issuer-side cryptographic exchange and Mastercard MDES network tokenization. We are now looking to extend this integration to support Apple Pay Web Push Provisioning, allowing cardholders to add eligible cards to Apple Wallet directly from our web application. We would appreciate guidance on: -The process for enrolling in Apple Business Register (if required) -Enabling Web Push Provisioning for an issuer profile Required entitlements or provisioning certificates Any additional onboarding steps specific to issuer-level Web provisioning We understand that Web Push Provisioning requires issuer-level enablement beyond standard Apple Pay on the Web, and we would like clarification on the correct path to activate this capability. Thank you in advance for your guidance.

Our client's site uses Apple Pay, and once a month we get a series of email notifying us that the domain verification is about to expire: Your website domain that uses Apple Pay has an SSL Certificate that expires on Oct 11, 2020. We were unable to automatically to reverify your domain. To ensure uninterrupted use of Apple Pay on your website, revalidate your domain by Oct 11, 2020 in Certificates, Identifiers & Profiles. The site uses Let's Encrypt to automatically renew its SSL cert monthly. Every time that happens, we need to log into the Apple Developer tools, navigate to Certificates, Identifiers, and Profiles -> Identifiers -> Merchant IDs -> ID -> Merchant Domains, then download the file and drop it onto the server with SFTP. It's a pain. Is there a way to automate this process (or better yet, stop it from happening)? I can't imagine monthly-renewing SSL certificates is a particularly uncommon thing.

Hi everyone, We are integrating Apple Pay on the Web, and we're trying to get the automatic renewal of the domain verification working according to the documentation: https://developer.apple.com/documentation/apple_pay_on_the_web/maintaining_your_environment Initially the domain verification is successful, but then the automatic renewal does not work. We keep getting the emails with the subject "Your domain will expire soon.", but they only say "We were unable to automatically to reverify your domain." without any further details. We confirmed that the site's SSL certificate has already been renewed by the time Apple attempted the renewal of verification, the certs are renewed 30 days before their expiry (using Let's Encrypt). So according to the docs, at least the renewal attempts 15, and then 7 days before the expiry should be successful. One example domain is this one: https://www.kayak.com/.well-known/apple-developer-merchantid-domain-association.txt, but we have the same issue for all our other domains as well. Does anyone have suggestions how to troubleshoot this further? (I tried creating a support ticket, but they basically replied that they're non-technical, and just linked me to the documentation. I've seen others complaining about this too, but couldn't find a conclusive solution, so I thought I'd signal boost and create a fresh topic to see if there are any more recent findings about this problem.) Thanks! Regards, Mark

Environment macOS 26.5.1 (Build 25F80) Safari 26.5 Apple Pay JS API version 8 Using https://applepay.cdn-apple.com/jsapi/v1/apple-pay-sdk.js Reproduces on the staging website (Does not reproduce on the production website with non sandbox account) Signed into a Sandbox Tester Apple ID, with a test credit card registered exactly per Apple Pay Sandbox Testing — this is the only card in Wallet on the laptop Merchant validation is performed by our staging backend against our real (non-sandbox) merchant identity/certificate — i.e. a sandbox tester card being evaluated against a staging merchant session, which per the sandbox testing documentation is the expected/supported setup for testing on a live site without a separate merchant sandbox environment Summary After completeMerchantValidation() succeeds and the merchant session is accepted, the payment sheet still terminates with PKPaymentAuthorizationStateFatalError a few hundred milliseconds later, right after the native side logs a second "Evaluating merchant session using PROD trust policy." for the same session. The user sees "Payment failed" and the sheet closes. This happens on the very first attempt, with no user interaction beyond tapping the Apple Pay button — no shipping address is even selected before the failure. Since the sandbox tester card + production merchant session combination is the setup the sandbox testing guide describes, we'd expect the sheet to proceed to onpaymentauthorized (Apple's sandbox docs describe payments as being processed as $0 test transactions in this mode) rather than fail natively before that stage is ever reached. Steps to reproduce Visit an item page with an Apple Pay button. Tap the Apple Pay button to open the payment sheet. The sheet presents normally; no interaction with shipping address or payment method is required for the failure to occur. Within ~1 second, the sheet dismisses and displays a "Payment failed" error state. Minimal reproduction of the JS side const session = new ApplePaySession(8, { countryCode: 'US', currencyCode: 'USD', supportedNetworks: ['visa', 'masterCard', 'amex', 'discover'], merchantCapabilities: ['supports3DS'], total: { label: 'Merchant', amount: '10.00' }, }); session.onvalidatemerchant = async () => { const merchantSession = await validateMerchantOnServer(); // succeeds session.completeMerchantValidation(merchantSession); // accepted — see log below }; session.onpaymentmethodselected = () => { session.completePaymentMethodSelection({ newTotal: { label: 'Merchant', amount: '10.00' }, }); }; session.oncancel = event => console.log('cancelled', event); session.begin(); We reproduced this with both our full checkout implementation and this stripped-down request object (no shipping contact required, no line items) — same failure either way, which rules out anything about our order/line-item data. What we expected The sheet to proceed to the biometric authorization step and dispatch onpaymentauthorized once the user confirms. What actually happens The sheet fails immediately with a PKPaymentAuthorizationStateFatalError transition, even though every JS-side completion call (completeMerchantValidation, the payment-method selection) succeeded and returned PKPaymentAuthorizationStatusSuccess. System log (captured via log stream --info --debug --predicate 'process == "Safari" OR process == "passd" OR process == "com.apple.PassKit.PaymentAuthorizationUIExtension"') 21:50:41.544 PaymentCoordinator::beginPaymentSession() -> 1 21:50:41.570 Received prepareWithPaymentRequest: <private> 21:50:42.297 PaymentCoordinator::validateMerchant() 21:50:42.563 PaymentCoordinator::completeMerchantValidation() 21:50:42.564 Received merchant session update with status:PKPaymentAuthorizationStatusSuccess session:<private> 21:50:42.564 Evaluating merchant session using PROD trust policy. <- 1st occurrence, passes 21:50:42.572 PaymentCoordinator::didSelectPaymentMethod() 21:50:42.572 PaymentCoordinator::completePaymentMethodSelection() 21:50:42.653 Evaluating merchant session using PROD trust policy. <- 2nd occurrence 21:50:42.656 State machine change state from ClientCallback to PrepareTransactionDetails with param: <private> 21:50:43.391 Task Completed: <private> 21:50:43.393 State machine change state from PrepareTransactionDetails to PKPaymentAuthorizationStateFatalError with param: <private> 21:50:43.393 Error Payment failed with fatal error <private> 21:50:45.130 PaymentCoordinator::didCancelPaymentSession() The first "Evaluating merchant session using PROD trust policy." line passes (the flow continues to didSelectPaymentMethod). The second occurrence is immediately followed by Task Completed and then the FatalError transition, which suggests PassKit re-validates the merchant session's trust a second time right before PrepareTransactionDetails, and that second check is what's rejecting the session — even though the identical session object was accepted moments earlier at completeMerchantValidation(). What we've tried / ruled out Confirmed every JS completion method (completeMerchantValidation, completePaymentMethodSelection) is called and returns success — no 30-second timeout, no missing completion call, no thrown exception on our side. Reproduced with a minimal, hardcoded ApplePayPaymentRequest (fixed $10.00 total, no shipping fields) — rules out anything about our real order/line-item/sales-tax data. Reproduced on the main branch and independently on our staging deployment running unmodified code — rules out anything specific to our recent frontend changes. The <private> redaction in the system log prevents us from seeing what specifically fails during the second trust evaluation. Confirmed the sandbox tester card and its registration follow the sandbox testing guide exactly — it's the only card on the device, and no other Wallet cards are involved. Question What does PassKit's second "Evaluating merchant session using PROD trust policy" check (immediately before PrepareTransactionDetails) actually validate, beyond what's already checked at completeMerchantValidation() time? Is a sandbox tester card being evaluated against a production merchant session expected to pass this second check, or does sandbox testing per the linked guide require something additional on the merchant/session side (e.g. a specific field on the merchant session, or a specific environment value) that our backend isn't setting? Is there a way to get an unredacted reason for the rejection — e.g. via a private-data-enabled log profile or another diagnostic — since the redacted system log alone doesn't surface one?

I am trying to start implementing the Push Provisioning (Apple Pay) process for my website. I configured a test-environment and already had a 'success' connectivity test before, even though I did not implement any TLS validation api. but for about two weeks, there is that "Environment connectivity test is unavailable due to production maintenance." message. I don't know if earlier i managed to pass the tests for real, or if that is exactly a bug Apple is working on. This message comes and goes at least 2-3 times, and you can't tell if the connectivity test works as expected or is bugged.

We had noticed “paymentCredentialsAvailable” is getting returned more from apple pay capabilities for some unexpected devices (our example is windows + chrome). Based off the documentation this should only be returning if this is linked to a wallet account w/ valid payment. From some investigation this appears to have changed from apple pay js v1.3.7 to v1.3.8 (latest). Previously the above windows + chrome example would return “paymentCredentialStatusUnknown” which is what would be expected in this case. Tried running chrome in icognito mode and clearing cookies just in case this check had some linkage to the apple account via QR code usage, but did not appear to affect the returned response. Unsure if this is a bug or a change to the logic, but doesn’t appear to be appropriately reflected in the documentation, also a change like this should not be appearing in a patch version. Has anyone else experienced this?

Hi,
 We’re implementing Apple Pay on the Web for a multi-tenant platform via a PSP. The PSP operates multiple HSM/clusters and gave us multiple CSRs, asking us to register all.
Our understanding: a Merchant ID can hold several PPCs over time, but only one is active at once. Questions Is there any supported way to keep more than one PPC active simultaneously for the same Merchant ID? If not, what does Apple recommend for web-only, multi-tenant setups: a single MID with PSP-side decryption & sub-merchant separation, or separate MIDs per brand/region? Any official guidance on PPC rotation and handling many domains for Apple Pay on the Web? links to official docs or prior Apple responses would be appreciated.

We are writing to report a recurring stability issue with the Apple Pay sandbox environment. We are using the official sandbox test cards provided on the Apple Developer website for our testing: https://developer.apple.com/apple-pay/sandbox-testing/ We are experiencing frequent, intermittent failures when attempting to add these sandbox cards to the Wallet for testing purposes. The issue typically occurs a couple of times per day. When the failure occurs, the card provisioning process fails unexpectedly. The issue is not limited to a single card; we have observed this behavior across all available card networks. In some instances, all cards (Visa, Mastercard, Discover, Amex) fail to provision simultaneously. At other times, the issue appears to be isolated to specific networks while others work correctly. Crucially, the issue appears to be temporary. After some time passes (ranging from minutes to an hour), we are able to add the exact same card successfully without making any changes to our test environment or configuration. We have diligently checked our setup to rule out configuration errors on our end. This includes verifying: The device is set to a supported region. We are signed in with a valid sandbox tester Apple ID. All other prerequisites for sandbox testing are met. The fact that the process works correctly at other times strongly suggests that this is a server-side stability issue within the Apple Pay sandbox environment rather than a persistent misconfiguration on our part. To help with your investigation, we have attached an image that demonstrates a failed attempt to add a card. Could you please investigate the stability of the sandbox card provisioning service? Please let us know if this is a known issue or if there is any further information we can provide. Thank you for your time and assistance.

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?

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/

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 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.

Hello, I am currently testing an Adyen integration with Sylius and need to verify Apple Pay with Cartes Bancaires in the sandbox environment. Could you please advise how Cartes Bancaires can be tested in Apple Pay Sandbox (e.g. cards details)? Thank you in advance for your guidance. Best regards, Grzegorz

I am working on implementing merchant token notifications. When calling this endpoint https://developer.apple.com/documentation/merchanttokennotificationservices/merchant-token-event-retrieval, the result contains a CardMetadata object with an expirationDate field (see https://developer.apple.com/documentation/merchanttokennotificationservices/cardmetadata). What is the format of this field? The spec only mentions that it has a maximum length of 8 characters.
