Hi,
You're here because you've had issues with your implementation of Wallet Extensions for Apple Pay In-App Provisioning or In-App Verification. To prevent sending sensitive credentials in plain text, create a new report in Feedback Assistant to share the details requested below with the appropriate log profiles installed.
Gathering Required Information for Troubleshooting Apple Pay In-App Provisioning or In-App Verification Issues
While troubleshooting Apple Pay In-App Provisioning or In-App Verification, it is essential that the issuer is able to collect logs on their device and check those logs for error message. This is also essential when reporting issues to Apple. To gather the required data for your own debugging as well as reporting issues, please perform the following steps on the test device:
Install the Apple Pay and Wallet profiles on your iOS or watchOS device. If the issue occurs on Mac, continue to Step 2.
Reproduce the issue and make a note of the timestamp when the issue occurred, while optionally capturing screenshots or video.
Gather a sysdiagnose on the same iOS or watchOS device, or on macOS.
Create a Feedback Assistant report with the following information:
The bundle IDs
App bundle ID
Non-UI app extension bundle ID (if applicable)
UI app extension bundle ID (if applicable)
The serial number of the device.
For iOS and watchOS: Open Settings > General > About > Serial Number (tap and hold to copy).
For macOS: Open the Apple () menu > About This Mac > Serial Number.
The SEID (Secure Element Identifier) of the device, represented as a HEX encoded string.
For iOS and watchOS: Open Settings > General > About > SEID (tap and hold to copy).
For macOS: Open the Apple () menu > About This Mac > System Report > NVMExpress > Serial Number.
The sysdiagnose gathered after reproducing the issue.
The timestamp (including timezone) of when the issue was reproduced.
The type of provisioning failure (e.g., error at Terms & Conditions, error when adding a card, etc.)
The issuer/network/country of the provisioned card (e.g., Mastercard – US)
Last 4 digits of the FPAN
Last 4 digits of the DPAN (if available)
Was this test initiated from the Issuer App? (e.g., yes or no)
The type of environment (e.g., sandbox or production)
Screenshots or videos of errors and unexpected behaviors (optional).
Important: From the logs gathered above, you should be able to determine the cause of the failure from PassbookUIService, PassKit or PassKitCore, and by filtering for your SEID or bundle ID of your app or app extensions in the Console app.
Submitting your feedback
Before you submit to Feedback Assistant, please confirm the requested information above is included in your feedback. Failure to provide the requested information will only delay my investigation into the reported issue within your Apple Pay client.
After your submission to Feedback Assistant is complete, please respond in your existing Developer Forums post with the Feedback ID. Once received, I can begin my investigation and determine if this issue is caused by an error within your client, a configuration issue within your developer account, or an underlying system bug.

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.

Apple Pay v2 (signedTransactionInfo) : how to verify new token format and migrate from legacy EC_v1?
I’m updating a legacy application that used Apple Pay v1 token format, and in my new revamped version I’m now receiving the newer Apple Pay v2 format.
The old (v1) payload looked like this:
php
{
"version": "EC_v1",
"data": "...",
"signature": "...",
"header": {
"ephemeralPublicKey": "...",
"publicKeyHash": "...",
"transactionId": "..."
}
}
In the new revamp (v2), Apple Pay returns this instead:
php
{
"signedTransactionInfo": "eyJhbGciOiJFUzI1NiIsIng1YyI6WyJNSUlF..."
}
From what I understand:
v1 tokens were elliptic-curve encrypted JSON objects containing a header and signature.
v2 tokens seem to be JWS (JSON Web Signature) strings using the ES256 algorithm, possibly containing transaction and subscription details inside.
Questions
Is there any official Apple documentation or migration note explaining the move from EC_v1 → signedTransactionInfo?
How should I verify or decode the new signedTransactionInfo payload?
Should the verification now use Apple’s public keys instead of the legacy Merchant ID certificate?
Are there any example implementations or SDKs that can handle both v1 and v2 formats during migration?
Is there a recommended way to maintain backward compatibility while transitioning existing users?
Goal
Ensure that my revamped app can handle Apple Pay v2 tokens securely while keeping the legacy v1 integration functional until all users are migrated.
Hi,
I understand that it's possible to add a virtual debit or credit card from a mobile app into the iOS Wallet using PassKit from the Apple SDK. However, I haven't come across documentation on how to achieve this directly from a web app. I found this article on Apple's support site (https://support.apple.com/en-gb/guide/security/secdc2567239/web), which mentions adding cards from a card issuer’s website, but it doesn’t provide details on the process.
Could you please confirm if it's possible to add a card directly from a web app without using a mobile app? If so, could you guide me to the relevant documentation?
Thanks in advance!
I developed a web app using .net c#. The app runs a workflow which included Apple payment. App can work on any browser of any device (even non-IOS).
When the app is browsed using PC windows Chrome browser, the payment sheet will show with QR code to scan using iPhone. If I cancelled the pop-up by clicking on X without scanning the code, and then returned to idle screen and performed another payment, I will reach paymentRequest.Show() but nothing will show and no errors are logged in console.
Note that:
I use Payment Request API
The issue appear on the second payment.
The issue will be solved once I refresh the page.
My app supports both single and separate pages mode and issue appear on both.
I used to see an error "Uncaught NotSupportedError: Failed to execute 'define' on 'CustomElementRegistry': the name apple spinner has already been used with this registry. So I thought the issue might be in loading the apple SDK script multiple times, and solved the issue to be loaded only once. The error disappeared but the issue persist without errors.
Hi everyone,
I’m encountering a strange issue with Apple Pay in our React Native iOS app using the Stripe React Native SDK.
Summary of the Problem:
• Apple Pay shows up as an available payment method inside the Stripe Payment Sheet.
• When I tap Apple Pay, the Apple Pay sheet opens normally.
• After confirming payment, the Apple Pay sheet immediately closes, and nothing happens.
• No payment is created and no request reaches Stripe’s servers.
On Stripe Dashboard the PaymentIntent remains incomplete, with no errors, which means the failure happens before Stripe receives anything.
Environment
• React Native with @stripe/stripe-react-native
• StripeProvider configured with:
<StripeProvider
publishableKey={...}
merchantIdentifier="merchant.com.app.venga"
stripeAccountId={...}
urlScheme="venga"
>
Apple Pay works on our web checkout with the same merchant identifier.
We have verified all of the required Apple Pay setup:
• Merchant ID exists, active, and matches exactly.
• Merchant ID added to the iOS app target in Xcode → Signing & Capabilities.
• Apple Pay capability enabled.
• Merchant domain is verified (web checkout works).
• Apple Pay certificate and merchant certificate are valid.
• Stripe publishable key and merchantIdentifier are correct.
• Stripe SDK correctly initialized.
• Device region supports Apple Pay.
Extra Observations:
• The PaymentIntent’s allowed_payment_methods includes "card" and Apple Pay does appear in the payment sheet.
• But after tapping Pay → the Apple Pay sheet closes instantly.
• There is no callback with an error, and nothing appears in Stripe logs.
• We are testing in Sweden. As far as I know Apple Pay should work fine here.
Questions:
What could cause the Apple Pay sheet to dismiss instantly after attempting a payment?
Could this be caused by a merchant ID mismatch—even if Apple Pay appears in the sheet?
Is there any Apple-device-level requirement (region, wallet config, card type) that could cause this silent failure?
Is there a way to get more detailed logs when Apple Pay closes before Stripe receives anything?
Any help or suggestions would be greatly appreciated. Thanks!

Hello Apple Team,
I’ve encountered a regression in iOS 26.1 when building my app with Xcode 26 (iOS 26 SDK).
The issue affects PKPaymentButtonType.plain, which now renders as fully invisible and produces transparent snapshots, even though the same code worked correctly in previous Xcode/iOS versions.
This has a real-world impact because many apps generate static images from PKPaymentButton for payment selection UIs using UIGraphicsImageRenderer, layer.render(in:), or custom snapshot utilities.
When using
PKPaymentButton(paymentButtonType: .plain, paymentButtonStyle: .black)
on iOS 26.1, when built with Xcode 26, the button:
Appears blank / invisible
Cannot be snapshotted
Produces a fully transparent UIImage, even though the CGImage object exists
Behaves differently than older SDKs (Xcode 16.x / iOS < 26.1
This regression only appears when compiling with the new SDK.
Other button types work fine.
Expected Behavior
.plain button should render glyphs as documented
snapshot generated via UIGraphicsImageRenderer or drawHierarchy(in:) should produce a visible image
Behavior should be consistent with older SDKs unless explicitly deprecated in release notes
Expected Behavior
.plain button should render glyphs as documented
Snapshot generated via UIGraphicsImageRenderer or drawHierarchy(in:) should produce a visible image
Behavior should be consistent with older SDKs unless explicitly deprecated in release notes
Actual Behavior
.plain button renders no glyph at all
Snapshot image is fully transparent (alpha = 0), even though size and CGImage metadata are correct
Only happens when built with Xcode 26 SDK
Same build from Xcode 16.x does not reproduce the issue
Steps to Reproduce
Create a minimal sample project in Xcode 26
Add the following code:
let button = PKPaymentButton(paymentButtonType: .plain, paymentButtonStyle: .black)
button.frame = CGRect(x: 0, y: 0, width: 180, height: 48)
let renderer = UIGraphicsImageRenderer(size: button.bounds.size)
let image = renderer.image { _ in
button.drawHierarchy(in: button.bounds, afterScreenUpdates: true)
}
print(image)
Run on iOS 26.1 device or simulator
Observe that:
The button appears visually empty
The generated image is fully transparent
Environment
Xcode: 26.x (iOS 26 SDK)
iOS: 26.1 (iPhone 15 Pro tested)
Device: Real device
Framework: UIKit + PassKit
Button type: .plain ONLY
Other types: .pay/.buy/.checkout = OK
I’m restructuring my business and want to remove Apple Pay. I use Woocommerce Square for payments. Do I do it in the Square dashboard or here? I honestly can’t remember how I set it up. I’m not a developer. I’m a farmer and work on my own website. Thanks!
During our Apple Pay integration testing, we encountered an issue that we're unsure how to resolve. Below are the steps we followed:
Created an Apple Pay sandbox test account for Raul and added a test card, following the documentation here: https://developer.apple.com/apple-pay/sandbox-testing/
Opened the Golfmanager platform and initiated a booking.
For payment, selected Apple Pay as the method.
Raul clicked the Apple Pay button on the Golfmanager UI.
He scanned the QR code using his iPhone, logged in with the test account.
Apple Pay began validating our merchant identity and retrieved the wallet token to proceed with payment.
The Apple Pay payment sheet appeared on Raul's iPhone, showing the card details and the amount requested by Golfmanager.
Suddenly, the Apple Pay sheet closed unexpectedly, and we have no insight into what went wrong or what might be missing on our end.

Hi,
We're experiencing an issue with verifying our domain for Apple Pay on the web. It's currently stuck in the "Pending" state despite meeting the listed requirements. The domain in question has been verified once successfully but one month later when we renewed the SSL, we were unable to verify the domain again. Please note that the new certificate's CA chain has been changed.
A) The "apple-developer-merchantid-domain-association.txt" file is publicly accessible at the following location:
/.well-known/apple-developer-merchantid-domain-association.txt
B) We've also ensured that the following IP ranges are whitelisted:
17.32.139.128/27
17.32.139.160/27
17.140.126.0/27
17.140.126.32/27
17.179.144.128/27
17.179.144.160/27
17.179.144.192/27
17.179.144.224/27
17.253.0.0/16
17.23.4.96/27
17.132.108.64/26
17.23.24.32/27
17.23.19.0/27
17.157.40.128/27
17.157.44.128/27
17.157.32.0/27
C) Our servers support TLS 1.2 already.
D) "ECDHE-RSA-AES128-GCM-SHA256" cipher suite has been used, so we believe all necessary criteria are satisfied.
However, when we attempt to verify the domain, we receive the following error message:
"Domain verification failed. Review your TLS Certificate configuration to confirm that the certificate is accessible and a supported TLS Cipher Suite is used."
Could you please advise why the verification is failing, or let us know if there's anything we might have missed?
Best regards,
Mehdi
We are attempting to integrate the Apple Pay service into our website and have successfully verified our domain with Apple manually. However, we consistently receive an 'ApplePay reverify failed' email a month before the expiration time. Upon checking, we updated the SSL certificate for the domain before receiving the email, and the link still works fine in the browser. We would greatly appreciate any feedback from someone who can help us with this issue.
We have an Apple Pay account and have successfully created and verified the payment processing certificate in our Apple Developer account.
When initiating an Apple Pay payment, the Apple session is created successfully with the correct data return from api , but it is not accepted with the error: “Payment not completed.”
The issue occurs even though the merchant validation step works without errors.
Our websites where this is happening are:
https://magicdeliver.com/
https://www.pulsarmodular.com/
Could you please help us identify the cause of the issue and guide us on resolving it?
I am attempting to verify my domain
https://technoq.genesistechnologies.tech
for use with Apple Pay Merchant ID. However, when I attempt verification, the process fails with the message:
“Domain verification failed.”
Unfortunately, no additional details are provided.
I have already completed the following steps:
Downloaded the verification file apple-developer-merchantid-domain-association.txt.
Placed it in the .well-known directory as instructed.
Confirmed that it is publicly accessible at:
https://technoq.genesistechnologies.tech/.well-known/apple-developer-merchantid-domain-association.txt
Verified that a valid SSL certificate is configured for the domain.
Could you please advise on why the verification might be failing and what additional steps I should take to resolve this issue?
I've encountered an issue where we need multiple domain associations with separate Apple Pay implementations.
Briefly, we have a /.well-known/apple-developer-merchantid-domain-association already setup with Stripe, and now we need another, different version of the file to get setup with FreedomPay. FreedomPay insists this file represents a three-way relationship between all parties and I have no reason to disbelieve them.
I'm wondering if anyone has encountered this or if there is a standard procedure. I'm currently trying to find documentation on the exact way Apple Pay verification interacts with this file to see if we can produce it dynamically.
Hello all,
I’m helping a customer integrate Apple Pay, and I’m seeing a behavior I can’t fully explain. I hope someone here can help clarify whether this is expected or whether it’s a bug / misconfiguration on my side.
Currency: RSD (Serbian Dinar)
Amount: 3.45 RSD (two decimals)
Result: Apple Pay cancels the payment automatically when the amount includes decimals, without even displaying the paymentsheet.
Things I have checked:
ISO 4217 defines RSD with 2 minor units, so fractional amounts like 3.45 should be valid.
Processors treat RSD as a two-decimal currency.
Apple’s documentation does not provide a per-currency decimal rule table.
In testing, whole-number RSD amounts succeed, while fractional amounts (e.g. 3.45 RSD) fail. I did not encounter this problem with other currencies like EUR, USD.
Has anyone encountered this issue before?
ApplePaySession.applePayCapabilities() started returning applePayUnsupported in third-party browsers
We rely on ApplePaySession.applePayCapabilities() to decide whether to show the Apple Pay button. We use two different merchant IDs for non-prod/prod environments, and encountered a change in behavior where this API now returns different results.
These merchant IDs are generated from a third-party provider Adyen. However, Adyen has informed us that they are unable to identify the root cause of the issue and advised us to seek assistance directly from Apple Pay support.
Timeline
Last known working date: 13/08/2025
Issue first noticed: 18/08/2025
Environment Details
Apple Pay JS API version 1.latest
Browsers Tested: Third party browsers including Chrome/139.0.0.0, Firefox/141.0
Browsers with ApplePaySession built-in (like iOS Chrome, iOS Safari, and macOS Safari) are working fine
Framework Stack: Angular v18.1.3
(important) no configuration setup in Apple dev account, merchantId is generated from a third-party provider Adyen.
Current Execution Flow:
Apple Pay JS API script element is injected
<script type="text/javascript" async="" src="https://applepay.cdn-apple.com/jsapi/1.latest/apple-pay-sdk.js"></script>
Triggers below to check apple pay readiness, different ${merchantId_credential} is used:
await window.ApplePaySession.applePayCapabilities(`${merchantId_credential}`);
(**ApplePaySession is a valid object at this point)
Observed that different paymentCredentialStatus is returned
// nonprod env
{
"paymentCredentialStatus": "applePayUnsupported" // unexpected
}
// prod env
{
"paymentCredentialStatus": "paymentCredentialStatusUnknown"
}
The same code is executed in each environment and the behaviour was also the same, but has changed since then.
Side notes
By checking the SDK’s internal code, we saw that in third-party browsers it makes an extra call to the following endpoint. Responses from this call also come back differently depending on the merchantId.
When invoking below:
curl -X POST \
https://smp-paymentservices.apple.com/paymentservices/v3/checkStatus/merchant/{merchantId} \
-H 'Content-Type: application/json' \
-d '{
"initiative": "web",
"initiativeContext": "env_specific_domain"
}'
Our non-prod environment returns {"registered":false} while using prod's merchantId and domain it returns {"registered":true}. We thought the issue might be domain-related since the environments are on different domains, but so far, no luck.
The main questions we're looking to resolve are:
Why did the behavior change at a certain point despite no code changes? How should we approach this investigation, and what specific requests should we be making to the Adyen team?
Why does the response from the call to https://smp-paymentservices.apple.com/paymentservices/v3/checkStatus/merchant/{merchantId} return different results? Perhaps this could provide a clue regarding the question above?
We noticed that canMakePayments() is returning true, so we could consider using that as a workaround. Would it be safe to change the source of truth relying on canMakePayments() for displaying Apple Pay?
There is a concern that this issue may also occur in our production environment, so we would appreciate assistance in understanding what is happening and finding a resolution.
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.
Hi,
We have app in which we take donations from people and send to non-profit organisations. I have read that Apple Pay can be integrated on non profit platforms to take donations, but we are middle man, we are not non profit .. we take donations, cut our platform fees and then sent to donations to non profit orgs.
My question is can we integrate Apple Pay in our iOS app to take donations from apple? as we have integrated Apple Pay on the web.
