ApplePayRecurringPaymentRequest Query
Hi , This is regarding the ApplePayRecurringPayment Request and Apple Pay on Web functionality. Does Apple Pay on web providing functionality that collects payments from the stored credit card issuer bank (or) it only provides secured wallet functionality that provides a token which then has to be utilized to send a seperate payment request through a third party payment gateway to collect the payments from the credit card issuer bank. thanks

Problem with cert validation and button show
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/

NotSupportedError, The payment method is not supported
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?

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.

Why is the Apple Wallet Url Verification different between the ios18 and ios26
Basic information: The issuer has implemented the feature to active Apple Card via URL Verification. The feature implemented by issuer is supported both in the APP and Clips. When Apple queries the activation method from UnionPay, UnionPay returns the "URL" activation method to Apple. Additionally, the apple-app-site-association file has been correctly deployed, and the configuration for Universal Links has been completed. Both the APP and Clips have undergone testing for Universal Link calls. The desired experiece is that when the APP is installed, Apple Wallet launches the APP, and the user completes the activation within the APP, and if the APP is not installed, Apple Wallet calls Clips, and the user completes the activation in Clips. Problem description: Under iOS 17 and iOS 18, when triggering Apple Pay card activation, the APP or Clips can be called as expected, and the activation can be completed well. However, Under iOS 26, regardless of whether the APP is installed, under the same circumstances, an internal browser within Apple Wallet opens to access the H5 page corresponding to the URL, instead of redirecting to the APP or Clips. Please assist in confirming whether this is a new feature of iOS 26 and how the same user experience can be achieved.

Apple Wallet Push Token length
For the pushToken sent by APNS to register a wallet pass for update notifications, is there a max length or size that APNS will send? I save the token in my database and have it defined as varchar(256), but I have had some instances where the pushToken is larger than that. I'd like to know if there's an absolute max size that APNS will send. Then I'll know if I should reject requests with tokens larger than what's expected, and/or if I need to make the token size larger in the database.

How to use Extended Virtual Addressing and Increased Memory Limit services correctly?
During the development of our 3D game project, we encountered high memory usage requirements. To address this, we enabled Apple’s Extended Virtual Addressing (EVA) and Increased Memory Limit services. We have confirmed that both services were enabled in the developer backend as well as in Xcode, and we also used updated development and distribution certificates when building the app. However, in our validation process, it seems that EVA and Increased Memory Limit are not taking effect — the game still experiences memory overflow and crashes. Could you please advise: The correct steps to properly use Extended Virtual Addressing and Increased Memory Limit; How we can confirm whether these services are functioning as expected?

Format of expirationDate on Merchant Token Event
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.

Handling Empty in_app Data in iOS Order Verification and Verification Result in receipt.app_item_id
Body: Hello, We are currently implementing iOS order verification and have encountered an issue. Some of the receipts we verify return with an empty in_app array, which makes it impossible to determine whether there is a valid in-app purchase. Below is the code we’re using for verification and the result we receive: Code Example: public function iosVerifyReceipt($receipt, $password = '', $sandbox = false) { $url = $sandbox ? 'https://sandbox.itunes.apple.com/verifyReceipt' : 'https://buy.itunes.apple.com/verifyReceipt'; if (empty($password)) { $data = json_encode(['receipt-data' => $receipt]); } else { $data = json_encode(['receipt-data' => $receipt, 'password' => $password]); } $ch = curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); $result = curl_exec($ch); curl_close($ch); $result = json_decode($result, true); $result = $result ?? []; $result['sandbox'] = $sandbox; if ($result['status'] != 0) { Log::warning('ios verify receipt failed', ['receipt' => $receipt, 'result' => $result, 'sandbox' => $sandbox]); if ($result['status'] == 21007) { return $this->iosVerifyReceipt($receipt, $password, true); } } return $result; } // Order validation check if (empty($result) || $result['status'] != 0) { throw new BadRequestHttpException("Ios Order Verify Error"); } $appItemId = $result['receipt']['app_item_id'] ?? ""; if ($appItemId != MY_APP_ID) { throw new BadRequestHttpException("Ios Order Verify Error"); } $inApp = array_filter($result['receipt']['in_app'] ?? [], function ($item) use ($transactionId, $order) { return $item['transaction_id'] == $transactionId && $item['product_id'] == $order->getProductId(); }); if (empty($inApp)) { throw new BadRequestHttpException("Ios Order Verify Error"); } Array ( [receipt] => Array ( [receipt_type] => Production [adam_id] => * [app_item_id] => * [bundle_id] => * [application_version] => * [download_id] => * [version_external_identifier] => * [receipt_creation_date] => 2025-02-11 04:06:47 Etc/GMT [receipt_creation_date_ms] => * [receipt_creation_date_pst] => 2025-02-10 20:06:47 America/Los_Angeles [request_date] => 2025-02-11 15:54:56 Etc/GMT [request_date_ms] => * [request_date_pst] => 2025-02-11 07:54:56 America/Los_Angeles [original_purchase_date] => 2025-02-11 04:02:41 Etc/GMT [original_purchase_date_ms] => * [original_purchase_date_pst] => 2025-02-10 20:02:41 America/Los_Angeles [original_application_version] => 5511 [preorder_date] => 2025-01-17 21:12:28 Etc/GMT [preorder_date_ms] => * [preorder_date_pst] => 2025-01-17 13:12:28 America/Los_Angeles [in_app] => Array ( ) ) [environment] => Production [status] => 0 [sandbox] => ) Problem Description: • We are noticing that in some orders, the in_app array is returned as empty. This causes difficulty in verifying the presence of in-app purchases. • Our validation logic assumes that if in_app is empty, the order is invalid, but we would like clarification on whether this is correct or if such a scenario is normal under certain conditions. Actions Taken: • We have reviewed Apple’s documentation and other related resources, but no clear explanation is given about when in_app might be empty. • Can we safely rely on an empty in_app array to consider the order invalid, or should we investigate further for potential issues like delays or errors during the verification process? We would appreciate your guidance on how to handle such cases. Thank you for your support!

iPhone iWatch sending ATQB response during ECP polling causing detection of collision
Hi Support, When the applepay express transit option is used on emv payment cards, like this iPhone - Open “Settings” → “Wallet & Apple Pay” → “Express Transit Card”. And a emv single card has been enabled under Express Transit And on transit reader Apple Enhanced contactless Polling support is provided, ( with VAS not supported, user authentciation not supported) Sometimes ATQB response also comes from the iPhone or iWatch instead of the ATQA response, and then it causes the transit reader to report as collision error in the polling.

ApplePay: Flexible payments/scheduling
On Applepay's docs it talks about the ability to do "flexible" payments and scheduling for future purchases. We need to be able to make only a single approval of an Apple payment for multiple submissions later on. Think, deferred payments at an arbitrary schedule without presenting the ApplePay dialog each and every time. The docs suggest that may be possible, but are maddeningly vague on how to do that. Is it possible or not? Can we store an approved merchant's token for example and leverage that for future transactions?

Apple Pay Domain Verification: .txt Extension Confusion
Hi all, I’m running into a confusing issue with Apple Pay domain verification. Apple’s documentation says to host the verification file at: https://yourdomain.com/.well-known/apple-developer-merchantid-domain-association And the portal itself seems to expect the file to be served with .txt extension during verification. My first verification passed, but subsequent checks are failing — and I’m wondering if this mismatch is the cause. Should I Keep the .txt and configure my server to serve it at both paths? Would appreciate any insights or official clarification. Thanks!

Test Flight Test app UI Currency code error
When running the test app with test flight before actually opening the app, the execution region is Korea and the country code is Korea, but the currency code on the payment screen is displayed as dollars or euros instead of won. In the payment settings, the currency code is set to won for Korea and dollars for the United States, and the European region is not set at all, but in some phones it is displayed as euros, and in some phones it is not like this, and in some cases it is displayed as won normally.

Unable to retrieve already provisioned passes via Apple Wallet Extension
We have updated the PNO metadata to include the associatedApplicationIdentifiers for our wallet extensions and the issuer app. While we are able to successfully provision the card to Apple Wallet via pull provisioning, we are unable to retrieve the payment passes that have already been provisioned. How can we address this issue? let passLibrary = PKPassLibrary() let paymentPassLibrary = self.passLibrary.passes(of: .secureElement) paymentPassLibrary is an empty array even though we have passes provisioned.

Unable to Provision Payment pass to Apple Wallet via Wallet Extensions.
We are working with two types of wallet passes. Provisioning works successfully for one pass type via wallet extensions, but the same process is not functioning for the other. For the second pass type, we are able to generate the required data for pull provisioning and send it to Apple. Additionally, in-app push provisioning for this pass type completes without issue. We would appreciate guidance on how to further debug and resolve this provisioning problem.

Device selection on Apple Pay In-App provisioning is incorrect
I am encountering an issue with the in-app provisioning flow using PKAddPaymentPassViewController. Specifically, when presenting the controller to allow users to add a pass to Apple Wallet, the device selection screen is showing all the devices, even after setting the primaryAccountIdentifier on the PKAddPaymentPassRequestConfiguration. Here's the context: I'm using PKAddPaymentPassViewController for in-app provisioning. I provide a valid primaryAccountIdentifier in the configuration. But after adding the pass, if i print back the primaryAccountIdentifier it displays some other value different than the identifier i had set(Example masked identifier: FAPLMC1GB000000066aa4xxxxxxxxxxxa744f16axxxxxxxx). The provisioning flow works, but the device list shown to the user includes all the devices (e.g., Apple Watches and iPhone even though it is already added to Apple Watch or iPhone).
