Gathering Required Information for Troubleshooting Apple Pay In-App Provisioning or In-App Verification Issues
Hi, You're here because you've had issues with your implementation of In-App Provisioning 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.

Integrating Apple Pay into an HTML inline frame (iframe) on your website
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.

Issue with Apple Pay Integration in WKWebView
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?

In-app provisioning for Apple Pay
We created apps for many credit unions in Canada. Some of those apps has the feature to directly add users' debit cards to Apple Wallet (which is called by Apple as "in-app provisioning"). The feature has been working fine for at least 6 years for many credit unions. Recently, after updating one of those existing apps, we found out that the in-app provisioning is no longer working. Found it very strange, as we didn't touch the code base related to this feature for a very long time. One thing we found out is that the option to add in-app provisioning entitlement is missing during generating "provisioning profile" for the app. Is this a misconfiguration by App? Or do we need to request for additional entitlement migration as mentioned in the page: https://developer.apple.com/help/account/reference/provisioning-with-managed-capabilities ? Apple, please help, it's rather urgent.

The possibility of certificates renewal on "master account" without creating new merchant identity certificate and key stores.
Hello! We use Apple's "master account" scheme to register new clients trough API due to the fact that the number of merchant IDs in a developer account cannot exceed 100 records. It's been almost a year since we successfully used the master account ( ex. "merchant.com.xxx") and register clients via Postman. At the moment, the certificates for the master merchant ID start to expire on July 11 which will affect all customers which is under Master ID. We know that when updating certificates at the identifier level(our master id), new universal identity certificate files that we use to send to the merchants (merchant_id.pem, privkey.key) will be generated for authentication on the merchant side, as well as a new keystore. Since many of our clients are integrated with current files and keystores and have live traffic, we would like to know—is it possible to update certificates on the master account without changing the keystores and certificate identities? The impossibility of this will entail a large gap when switching to new certificates. Thanks in advance for your answer.

Apple Wallet not showing correct amounts for grocery delivery platform
We are observing unexpected behavior in Apple Wallet for transactions processed via an online delivery platform. Here is the specific flow: Initial Authorization: The original order was placed for $22.30. Order Amendment: The user added an item 10 minutes later for $6.20, bringing the total to $28.50. The Issue: Apple Wallet only displays the $6.20 transaction. The initial $22.30 amount is not visible in the transaction list. Technical Verification: We confirmed that both backend authorization messages for the original amount and the add-on were approved. We verified that the final settlement amounts correctly reflect the sum of both charges ($28.50). We have confirmed the transaction lifecycle completed successfully on our end. Despite this, the customer only sees the $6.20 entry in their Wallet history, which creates confusion as it doesn't reflect the total spent. Has anyone encountered this sync issue between settlement totals and Wallet display, or is there a specific way we should be linking these related authorizations? Thanks!

suppressing express mode when using widget
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.

WCSessionDelegate not being called in the Apple Wallet Extension With UI
Hi, we are implementing the push provisioning via the Apple Wallet Extension starting from the example at https://developer.apple.com/documentation/passkit/implementing-wallet-extensions. To correctly manage the push provisioning on Apple Watch, specifically for a card tokenised in the iPhone but not in the Watch, we need to know if there is a connected Apple Watch to the iPhone. We are using the following code from the Apple Wallet Extension example to detect whether there is a connected watch: WCSession* session = [WCSession defaultSession]; session.delegate = delegate; [session activateSession]; In the main target of the app, at the end of the activation the system correctly calls the delegate method: session:activationDidCompleteWithState:error: but we noticed it is not being called in the UI extension context (the one having NSExtensionPointIdentifier: com.apple.PassKit.issuer-provisioning.authorization). We don't understand why the delegate is not being called in the UI extension, can you please help? Thanks! Steps to Reproduce: Start with a card not added in the Apple Wallet app Open the Apple Wallet app Click on add card Select the app to launch the Wallet Extension flow The Apple Wallet Extension with UI is on screen and invokes the activateSession method, the delegate method is not invoked and session.isPaired returns "no".

Payment not completed in Apple Pay
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?

Payment sheet will not show in second payment
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.

Third party payment service
Hi everyone, I have a question regarding App Store approval. In my country, Apple In-App Purchases are not supported, so for users in unsupported regions we need to use a third-party payment provider. For countries where In-App Purchases are supported, we plan to use Apple IAP. Could you please advise on the correct approach to ensure the app complies with App Store guidelines and can be approved?

Scan Code like QR to pay by Apple Pay
During checkout at apple.com using a non-supported Apple Pay on the Web browser, apple.com presents a QR like code offering to "Scan Code with iPhone" to pay. The payment continues using Apple Pay on the iPhone after scan. We already offer Apple Pay and Apple Pay on the Web. Is this QR code option available for us for non-supported browsers? Could you point me to the docs to add it? Thank you.

Continuous "Tag mismatch" (AES-GCM) decrypting Apple Pay Web token - Suspected KDF / PartyV environment issue
I'm implementing payment processing with Apple Pay on the web, but I've been stuck right at the final step of the flow: decrypting the payment data sent by Apple. Here is a summary of my implementation: The backend language is Java. The frontend portal requests the session and performs the payment using the endpoints exposed by the backend. I created .p12 files from the .cer files returned by the Apple Developer portal for both certificates (Merchant Identity and Payment Processing) and I'm using them in my backend. The merchant validation works perfectly; the user is able to request a session and proceed to the payment sheet. However, when the frontend sends the encrypted token back to my sale endpoint, the problem begins. My code consistently fails when trying to decrypt the data (inside the paymentData node) throwing a javax.crypto.AEADBadTagException: Tag mismatch! I can confirm that the certificate used by Apple to encrypt the payment data is the correct one. The hash received from the PKPaymentToken (header.publicKeyHash) object exactly matches the hash generated manually on my side from my .p12 file. In the decryption process, I'm using Bouncy Castle only to calculate the Elliptic Curve (ECC) shared secret. For the final AES-GCM decryption, I am using Java's native provider since I already have the bytes of the shared secret calculated. (Originally, I was doing it entirely with BC, but it failed with the exact same error). We have exhaustively verified our cryptographic implementation: We successfully reconstruct the ephemeralPublicKey and compute the ECDH Shared Secret using our Payment Processing Certificate's private key (prime256v1). We perform the Key Derivation Function (KDF) using id-aes256-GCM, PartyU as Apple, and counter 00000001. For PartyV, we have tried calculating the SHA-256 hash of our exact Merchant ID string. We also extracted the exact ASN.1 hex payload from the certificate's extension OID 1.2.840.113635.100.6.32 and used it as PartyV. We have tried generating brand new CSRs and Processing Certificates via OpenSSL directly from the terminal. Despite having the correct ECDH shared secret (and confirming Apple used our public key via the hash), the AES tag validation always fails.et, the AES tag validation always fails. Given that the math seems correct and the public key hashes match, could there be an environment mismatch (Sandbox vs. Production) or a domain validation issue causing Apple to encrypt the payload with a dummy PartyV or scramble the data altogether? Any guidance on this behavior or the exact PartyV expected in this scenario would be highly appreciated.

Using a merchant session from an external website in PKPaymentAuthorizationController?
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

We verified that the final settlement amounts correctly reflect the sum of both charges ($28.50). We have confirmed the transaction lifecycle completed successfully on our end. Despite this, the customer only sees the $6.20 entry in their Wallet history, which creates confusion as it doesn't reflect the total spent. Has anyone encountered this sync issue between settlement totals and Wallet display, or is there a specific way we should be linking these related authorizations? Thanks!

Disable Shipping Address for Apple Pay
We are implementing Apple Pay on our website, but we only sell services and would prefer that the shipping address section of the Apple Pay modal doesn't require the shipping address and just show the billing address. Is there any way to achieve this?

suppressing express mode when using widget
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.

Apple Pay Web integration
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?

WCSessionDelegate not being called in the Apple Wallet Extension With UI
Hi, we are implementing the push provisioning via the Apple Wallet Extension starting from the example at https://developer.apple.com/documentation/passkit/implementing-wallet-extensions. To correctly manage the push provisioning on Apple Watch, specifically for a card tokenised in the iPhone but not in the Watch, we need to know if there is a connected Apple Watch to the iPhone. We are using the following code from the Apple Wallet Extension example to detect whether there is a connected watch: WCSession* session = [WCSession defaultSession]; session.delegate = delegate; [session activateSession]; In the main target of the app, at the end of the activation the system correctly calls the delegate method: session:activationDidCompleteWithState:error: but we noticed it is not being called in the UI extension context (the one having NSExtensionPointIdentifier: com.apple.PassKit.issuer-provisioning.authorization). We don't understand why the delegate is not being called in the UI extension, can you please help? Thanks! Steps to Reproduce: Start with a card not added in the Apple Wallet app Open the Apple Wallet app Click on add card Select the app to launch the Wallet Extension flow The Apple Wallet Extension with UI is on screen and invokes the activateSession method, the delegate method is not invoked and session.isPaired returns "no".

Payment not completed in Apple Pay
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?

Payment sheet will not show in second payment
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.

Third party payment service
Hi everyone, I have a question regarding App Store approval. In my country, Apple In-App Purchases are not supported, so for users in unsupported regions we need to use a third-party payment provider. For countries where In-App Purchases are supported, we plan to use Apple IAP. Could you please advise on the correct approach to ensure the app complies with App Store guidelines and can be approved?

Scan Code like QR to pay by Apple Pay
During checkout at apple.com using a non-supported Apple Pay on the Web browser, apple.com presents a QR like code offering to "Scan Code with iPhone" to pay. The payment continues using Apple Pay on the iPhone after scan. We already offer Apple Pay and Apple Pay on the Web. Is this QR code option available for us for non-supported browsers? Could you point me to the docs to add it? Thank you.

Continuous "Tag mismatch" (AES-GCM) decrypting Apple Pay Web token - Suspected KDF / PartyV environment issue
I'm implementing payment processing with Apple Pay on the web, but I've been stuck right at the final step of the flow: decrypting the payment data sent by Apple. Here is a summary of my implementation: The backend language is Java. The frontend portal requests the session and performs the payment using the endpoints exposed by the backend. I created .p12 files from the .cer files returned by the Apple Developer portal for both certificates (Merchant Identity and Payment Processing) and I'm using them in my backend. The merchant validation works perfectly; the user is able to request a session and proceed to the payment sheet. However, when the frontend sends the encrypted token back to my sale endpoint, the problem begins. My code consistently fails when trying to decrypt the data (inside the paymentData node) throwing a javax.crypto.AEADBadTagException: Tag mismatch! I can confirm that the certificate used by Apple to encrypt the payment data is the correct one. The hash received from the PKPaymentToken (header.publicKeyHash) object exactly matches the hash generated manually on my side from my .p12 file. In the decryption process, I'm using Bouncy Castle only to calculate the Elliptic Curve (ECC) shared secret. For the final AES-GCM decryption, I am using Java's native provider since I already have the bytes of the shared secret calculated. (Originally, I was doing it entirely with BC, but it failed with the exact same error). We have exhaustively verified our cryptographic implementation: We successfully reconstruct the ephemeralPublicKey and compute the ECDH Shared Secret using our Payment Processing Certificate's private key (prime256v1). We perform the Key Derivation Function (KDF) using id-aes256-GCM, PartyU as Apple, and counter 00000001. For PartyV, we have tried calculating the SHA-256 hash of our exact Merchant ID string. We also extracted the exact ASN.1 hex payload from the certificate's extension OID 1.2.840.113635.100.6.32 and used it as PartyV. We have tried generating brand new CSRs and Processing Certificates via OpenSSL directly from the terminal. Despite having the correct ECDH shared secret (and confirming Apple used our public key via the hash), the AES tag validation always fails.et, the AES tag validation always fails. Given that the math seems correct and the public key hashes match, could there be an environment mismatch (Sandbox vs. Production) or a domain validation issue causing Apple to encrypt the payload with a dummy PartyV or scramble the data altogether? Any guidance on this behavior or the exact PartyV expected in this scenario would be highly appreciated.

Using a merchant session from an external website in PKPaymentAuthorizationController?
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
