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.

Hi :) I'm new to app store connect, and I just want to verify what does it take to be able to test subscription for a new app that isn't approved yet using sandbox? Or is this not possible that the app has to be approved first? More context below: My app is a new app, I only submitted for review and I linked the subscription from the app’s In-App Purchases and Subscriptions section on the version page when submit it for review. It got rejected for now. When the app review status is both in-review and rejected, I've tried to test my subscription, where there is a button (like "subscribe"/"become a member") in my app that user can click on, which it calls ios's IAPProvider.startMembershipPurchase, I just get Error: [IAPService] Product not found: [<my_subscription_id>]. I ensured my subscription's product id in app store connect matches with the one in my code. I can see the "rejected" status both on my app and the subscription. So can anyone help clarify if the app has to be approved first in order to test subscription? Or am I missing any other setup? Or it might just be my code? Thanks in advance! Any info is super helpful!

Hey everyone, hoping someone here has run into this before. I have a fully functional App Clip (com.didyoucatchit.app.Clip) linked to my main app (com.didyoucatchit.app). The Clip builds and runs perfectly, but I’m seeing issues trying to enable Apple Pay for it. When I try to link my Merchant ID under the “On Demand Install Capable” capability in the Apple Developer portal, I get this error: A relationship in the provided entity is not allowed for this request. The relationship 'undefined' can not be included in a 'bundleIdCapabilities' request. Here’s what I have already configured and confirmed: App Clip capabilities in Xcode include: Apple Pay Payment Processing Associated Domains (appclips:app.didyoucatchit.com) Provisioning profile includes: Apple Pay Payment Processing Associated Domains In-App Purchase On-Demand Install Capable Entitlements file for the Clip: <key>com.apple.developer.associated-domains</key> <array> <string>appclips:app.didyoucatchit.com</string> </array> <key>com.apple.developer.in-app-payments</key> <array> <string>merchant.com.didyoucatchit.app</string> </array> <key>com.apple.developer.parent-application-identifiers</key> <array> <string>$(AppIdentifierPrefix)com.didyoucatchit.app</string> </array> Merchant ID (merchant.com.didyoucatchit.app) is active and connected to Stripe Stripe Apple Pay configuration matches the same merchant ID and certificate Both provisioning profiles have been refreshed and downloaded However: The portal still throws the “relationship 'undefined'” error anytime I try to modify the Clip’s capabilities In testing, Apple Pay doesn’t show up as a payment option in the Clip (using Stripe’s Payment Element integration) Questions: Is this a known issue with the Developer portal when linking App Clips to merchant IDs? Is there a specific way to re-establish the parent–child relationship between the main app and the App Clip so the bundleIdCapabilities request includes the proper relationship JSON? Are there any additional configuration steps required when using Stripe for Apple Pay inside an App Clip? System Setup: Xcode: 16.2 (build 16C5032a) macOS: Sequoia 15.3.1 iOS: 18.5 (testing on physical device) Merchant ID: merchant.com.didyoucatchit.app Main App ID: com.didyoucatchit.app App Clip ID: com.didyoucatchit.app.Clip Any help or insight would be hugely appreciated Thanks in advance!

I am currently working on decrypting Apple Pay tokens with Laravel PHP, and I have encountered a few uncertainties regarding the decryption process and the usage of AES-GCM. Could you please clarify the following points: Algorithm Confirmation: Am I using the correct algorithm for decrypting the data key? Specifically, I am utilizing AES-256-GCM with the algorithm ID "id-aes256-GCM" (2.16.840.1.101.3.4.1.46), as specified in the documentation. Is this the recommended algorithm for decrypting the Apple Pay token's data key? Authentication Tag: In the decryption process, it seems that an authentication tag is required, but I am not sure where to obtain it from. Could you confirm how the authentication tag is generated or provided during the encryption process? If the tag is part of the token or is transmitted separately, could you clarify where I can retrieve it in order to proceed with the decryption successfully? IV and Other Parameters: I am using an initialization vector (IV) of 16 null bytes (00000000000000000000000000000000) as specified in the documentation. Could you confirm that this is correct and aligns with the expected parameters for the AES-GCM decryption? Are there any other specific parameters or considerations I should be aware of when implementing the decryption of Apple Pay tokens? GCM vs Other Encryption Modes: Can you confirm that AES-GCM is the preferred and required encryption mode, or is there any flexibility to use other modes (e.g., AES-CBC) without compromising security? Your guidance would be greatly appreciated to ensure I am following the correct decryption procedure for Apple Pay tokens. Thank you in advance for your support.

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.

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 are facing an issue with Apple Pay address details while customers are placing orders on our production site. By default, the following values are being passed during checkout: First Name: ApplePay Last Name: Express Address: ApplePay Street When we manually enter these same details, our validation correctly prevents the order from being placed and displays an appropriate error message. However, on our production site, real customers are still able to successfully place orders with these exact details. Could you please help us understand: How these orders are being allowed to proceed despite the validation? Is this behaviour expected from Apple Pay ? How can we prevent orders from being placed with such placeholder address details? Please let us know if you need any additional information from our side. We have also attached an image showing the address details and the corresponding order number for reference. Thanks in advance for your support.

We have been informed by a third-party subscription tracking service(Adjust) that, due to the following specification of App Store Connect, it is not possible to connect an STG app (a non-published testing app) with their server: Specification: Since Apple’s API only allows access for apps that are already published, it is not possible to enable subscription tracking for iOS apps that are not yet published. Could you please confirm if our understanding of this specification is correct? Additionally, is there any method or recommended approach to verify subscription tracking behavior with an STG (non-published) app before the app is released? Thank you very much for your support.

We are an acquirer/payment provider offering Apple Pay. Our merchants use our hosted checkout to accept payments. After a user pays with Apple Pay on our checkout, the Wallet transaction record shows our checkout domain as the payee. We would like it to display the merchant’s brand/name so users can recognize or contact the merchant. Is there any parameter or configuration that controls what Wallet shows as the payee? For example, can this be set via a specific field/parameter, or is it strictly derived from the Merchant ID’s display name (or other Apple Pay configuration)? What is the correct approach for a PSP/acquirer to have the merchant’s brand shown in Wallet transaction record? Additional detail: The field in question is the merchant/payee name shown in the Apple Wallet receipt—directly under the transaction amount at the top of the receipt, and again beneath the “Total” line.

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.

Hi Guys, I am having an issue verifying a card when it is pending verification in the Apple Watch Wallet App and the iPhone Wallet. When the user verifies the card in the wallets, they are redirected to verification in my APP. However, the problem is that I don't know which application is calling, whether it is the Apple Watch or the iPhone, because the URL sends me the same serialNumber from the PKPASS. It is impossible to know if the user wants to verify and activate the card on the watch or the iPhone. Because I only receive the following information in the URL: myapp://app-url? passTypeldentifier=paymentpass.com.apple&action =verify&serialNumber=***** The serialNumber is the same from the iPhone Wallet and the Watch Wallet. func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool { let source = options[.sourceApplication] I try to retrieve the source, but it comes back null. It would be the only way to know the originating App. Can someone help me solve this problem?

Hi, For one of my projects, I am using the Web Drop-in component of Adyen PSP on a Salesforce B2B Commerce site. One of the payment methods is Apple Pay. The payment method is rendered, but the Apple Pay button is not clickable. We tried debugging it but could not identify the root cause. Could you advise how this issue can be fixed? Thanks

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.

Hi, we are implementing ID&V and there is a requirement regarding the flow for Apple Pay. In order to clarify the case I will describe the use case scenario or steps to reproduce first: add a card to the iPhone wallet app (yellow path verification required). Do not complete the ID&V process. add a card to the Watch via the Wallet inside the iPhone Watch app (yellow path verification required). Same as before, do not complete the ID&V complete ID&V process using the Issuer App either from iPhone or Watch. the Issuer app receives the application:openURL:options: callback on its AppDelegate. In the options dictionary, we can not see the UIApplicationOpenURLOptionsSourceApplicationKey populated (it is nil). At this moment, for the card we are adding there are now two tokens, both to be verified via ID&V process. One is on the iPhone and one is on the Apple Watch associated with the same iPhone. The url received at step 4 contains the serial number which identifies the digitized card and matches with both the tokens in the iPhone and in the Apple Watch. We need something to detect programmatically if the digitization process started from the iPhone Wallet app or from the wallet inside the Watch app. Could you please help us to identify how we could discriminate if the ID&V process has been started for the iPhone token or for the Apple Watch token? Thanks

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, We are working on integrating billing into our dating app, targeted at the Russian market. Our main requirement is to support subscriptions with automatic renewal and cancellation. We understand that, according to App Store Review Guideline, all digital subscriptions should use Apple In-App Purchase (IAP). However, we are unsure how this applies in Russia, where some local regulations may limit the use of non-Russian payment processors, and where not all Russian bank cards are accepted by Apple. Our question is: -For iOS apps in Russia, is it strictly required to use Apple IAP for subscriptions? -Are there any approved exceptions allowing integration with local processors such as Robokassa or YooKassa? -How are other developers currently handling subscriptions for the Russian market? We want to ensure full compliance and avoid any risk of rejection or removal. Thank you in advance for any clarification. Best regards, Dan

Hi, we are setting up Apple Pay on our website which sells only digital goods. We don't collect a shipping address because we aren't shipping anything. We want to use the user's billing address in order to show them the total amount (including sales tax) before they authorize the purchase. However, it seems that the billing address isn't always provided by Apple Pay before the payment is authorized. With Apple Pay, what is the recommended way of acquiring the user's billing address before they authorize the purchase? -- More details about our setup: We are using the Apple Pay JS API. In createPaymentRequest, we specify requiredBillingContactFields: ['postalAddress'], but per the docs, the address is provided after the user authorizes the transaction. That is too late for us because we want to show the sales tax before the user authorizes the purchase. We have attempted to work around this by getting the billing contact details in session.onpaymentmethodselected. For example: session.onpaymentmethodselected = function (event) { const billingContact = event.paymentMethod.billingContact; // Sometimes `billingContact` exists, but other times it does not } This doc states: Before the user authorizes the transaction, you receive redacted billing contact information in a callback event. The redacted information includes only the necessary data for completing transaction tasks, such as calculating taxes or shipping costs. But in practice, we've observed that sometimes no billing contact information is provided. When a user switches from one card to another, we seem to never get the billing contact associated with the newly selected card. Is there something we're missing?

We are developing a native iOS financial application called Tradu: Stocks, Forex, and CFDs (Apple ID: 6473443264), which embeds a WKWebView to render all user-facing logic. All user interactions—including authentication with MFA—occur inside this WKWebView. To access native functionality, we use postMessage() to communicate between the web and native layers. This approach has worked successfully for biometric authentication, for example. We are currently integrating Apple Pay In-App Provisioning and have a few questions regarding compliance with the documentation provided by our Issuer Host (Modulr). In the document titled Getting Started with Apple Pay: In-App Provisioning, Verification, Security, and Wallet Extensions (Version 4.0, February 2023), all examples are based on a fully native application. We’ve managed to integrate most of the In-App Provisioning flow via postMessage() up to the point of passing encryptedData to the Payment View. Apple Pay button inside WKWebView In Section 7: Frontend Overview, the user initiates the provisioning by tapping a native PKPaymentButton (SwiftUI example). In our case, this button is rendered inside the WKWebView, styled according to the Apple Style Guide. While the document references this approach as a “raw mark text supplement,” is this method acceptable and compliant with Apple’s UX and technical guidelines? MFA requirement before provisioning In Section 4: Security Guidelines, it is stated that the user must have passed MFA at least once before starting the provisioning flow. In our implementation, users must complete MFA on every login (including on recognized devices) before the provisioning UI becomes available. Even though this is not tied specifically to “unrecognized devices,” is our MFA requirement sufficient to satisfy Section 4.2? Summary: Is using a web-rendered Apple Pay button inside WKWebView (instead of a native PKPaymentButton) considered compliant? Is our MFA enforcement model (required on every login) aligned with the security requirements outlined in Section 4.2 of the Apple Pay In-App Provisioning documentation?

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/
