I'm implementing Apple Pay in my Flutter web app and I'm following the guidelines for domain verification using the apple-developer-merchantid-domain-association file. When I access the file at https://mydomain.com/.well-known/apple-developer-merchantid-domain-association through my web app, the browser silently downloads the file instead of displaying its content on the webpage. My question is: Is this the expected behavior for the apple-developer-merchantid-domain-association file? Should the browser download the file silently, or is there another step required, such as displaying the content on the webpage for verification purposes? I've consulted some resources and they indicate that the file download is the correct behavior. However, I'd appreciate confirmation from the community to ensure I'm implementing the verification process correctly. Summary is how do we know if apple has verified it?

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.

I'm encountering an issue with Apple Pay on both Wallet and the Watch app where the app name is not showing up on the back of the payment card(Card details). The pass was successfully provisioned, and everything seems to be working, but the expected app name or brand isn't displayed, and instead, I see the generic "Something went wrong. Try again Later" message. Do we need to configure something to get this displayed in Wallet app?

I have some questions related to MPAN. What is the format of an MPAN? Is it the same as DPAN? Is it PAN preserving format? Is a Cryptogram required and if yes, what kind of cryptogram? Is it the same format as DPAN? Thanks in Advance!

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 have used the ApplePayRecurringRequest parameter required for Apple Pay subscriptions, but during testing the payment, the Apple Pay payment page shown to the user remains the same as the one-time payment page, without any subscription information. Could you please check if there is an issue with our parameters or if there is an issue with the merchantIdentifier being used? Here is the ApplePayRequestData that we are using. { "supportedMethods": "https://apple.com/apple-pay", "data": { "version": 3, "merchantIdentifier": "***", "merchantCapabilities": [ "supports3DS", "supportsCredit", "supportsDebit" ], "supportedNetworks": [ "visa", "masterCard" ], "countryCode": "US", "recurringPaymentRequest": { "paymentDescription": "A description of the recurring payment to display to the user in the payment sheet.", "regularBilling": { "label": "Recurring", "amount": "4.99", "paymentTiming": "recurring", "recurringPaymentStartDate": "2025-06-02T16:00:00.000Z" }, "trialBilling": { "label": "7 Day Trial", "amount": "0.00", "paymentTiming": "recurring", "recurringPaymentEndDate": "2025-06-02T16:00:00.000Z" }, "billingAgreement": "A localized billing agreement displayed to the user in the payment sheet prior to the payment authorization.", "managementURL": "https://applepaydemo.apple.com", "tokenNotificationURL": "https://applepaydemo.apple.com" }, "additionalLineItems": [ { "label": "7 Day Trial", "amount": "0.00", "paymentTiming": "recurring", "recurringPaymentEndDate": "2025-06-02T16:00:00.000Z" }, { "label": "Recurring", "amount": "4.99", "paymentTiming": "recurring", "recurringPaymentStartDate": "2025-06-02T16:00:00.000Z" } ] }

When accessing https://applepaydemo.apple.com/payment-request-api, the "Approve with Side Button" prompt is displayed, but it does not appear when using our test domain. I implemented the Payment Request API based on the sample source code from the following URL. On an iPhone device, the Apple Pay payment screen is displayed, but the "Approve with Side Button" icon below the amount does not appear, and instead a spinning loading icon is shown continuously. Could you please help identify the cause? ■ Reference URL: https://applepaydemo.apple.com/payment-request-api ■ Changed parameter: "merchantIdentifier": "〇〇.dev" ■ Accessed domain: 〇〇test.com ■ Test device: iPhone 13 iOS: 18.4.1

Hello -- We're preparing to roll out Apple Pay on website in the next week but encountered some issues during testing. While we successfully processed transactions using a VISA card, we ran into errors when testing with other card brands. Has anyone come across this issue before?

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.

We are trying to develop a coupon/offer code module where our app users can avail a free trail offer for 2 months period after applying the code. We already had a subscription module with monthly & yearly subscriptions with 7 day free trial period. Now, we want to implement a offer/coupon module, where, a user can either select monthly or yearly subscription, and upon entering the offer/coupon code, they will get 2 months free trial (or) a discount on the chosen subscription. (this will overwrite the existing 7 day free trial). We are confused on choosing the type of “offer/coupon” from AppStore connect. In App Store connect, we have introductory offers, promotional offer & Offer codes. Based on our requirements, we have done research and found that we cannot implement the offer code & promotional codes in the develop environment as there is no possibility to test in Sandbox environment. We observed that we need to push the app to App store and upon approval, we need to implement “offer/coupon” module. Can some one please suggest or guide us on choosing the best solution for our requirement? Thanks in advance.

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.

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.

Dear Apple Developer Support, I would like to request a technical escalation to the engineering team regarding an ongoing issue with Apple Pay domain verification. Error returned by Apple Even though Apple’s request to our domain returns HTTP 200, the verification still fails with: resultCode: 13014 resultString: "Domain verification failed. Review your TLS Certificate configuration to confirm that the certificate is accessible and a supported TLS Cipher Suite is used." requestUrl: https://developer.apple.com/services-account/QH65B2/account/ios/identifiers/verifyDomain TLS Certificate Validation We performed a full TLS analysis: Certificate issued by Sectigo Public Server Authentication CA DV E36 (public trusted CA) Full and correct certificate chain No handshake errors Configuration fully valid SSL Labs rating: A From our side, the TLS configuration is confirmed to be correct. Accessibility of the .well-known file The file is publicly and accessible It returns 200 OK and the content is exactly identical to the file downloaded from the Apple Developer Portal, without any modification. Our network team confirmed that Apple’s verification request also receives HTTP 200 when pressing “Verify” in the Apple Developer Console. Network-side findings We monitored Apple’s request in real time. Findings: TLS handshake succeeds No cipher mismatch File delivered correctly Status: 200 OK No redirect or transformation applied Despite this, Apple still returns error 13014. Request for engineering review We kindly request that an Apple engineer verify the following: The actual TLS handshake performed by Apple's verification service (cipher suite, protocol negotiation, SNI, trust chain). Whether the Sectigo issuing CA is fully trusted and supported by your domain-verification backend. If there is an internal reason behind error 13014—since the external message does not provide actionable details. Whether the response is rejected for reasons other than TLS, given that the file is accessible and the request returns 200. The exact condition that leads Apple to report “TLS Certificate configuration is incorrect” in this case. This issue is blocking an urgent deployment and must be resolved as soon as possible. Existing case reference Case ID: 102760005987 We are fully available to provide: full response headers packet captures (PCAP) SSL/TLS diagnostics file integrity checks server configuration details or join a technical call (Teams / WebEx) Thank you in advance for the escalation.

Hi Apple Team and Developers, I’ve been testing the Top-up flow in our app via the TestFlight environment. Across multiple devices (around 10 tested), everything works fine with no issues. However, on one specific device — iPhone 14 Pro Max running iOS 18.6.2 — I’ve noticed an intermittent issue: When performing a Top-up, the Apple UI first shows a successful purchase confirmation. Immediately afterward, another UI prompt appears asking the player to re-enter their Apple ID password. At the same time, Apple returns a ghost string that we cannot use to verify the user’s package bundle ID. This creates potential confusion for users, as they see both a success confirmation and an unexpected password prompt. I’m unsure if this behavior is expected or if there’s a recommended way to handle or prevent this issue. Has anyone else encountered something similar, or does Apple have a suggested fix/workaround for this? For reference, here’s a short video of the issue in action: \🔗 https://drive.google.com/file/d/1Ml-QpEu4ocoxn-W3wEMsFMbXy2QdwbHB/view?usp=sharing Any guidance would be greatly appreciated. Thank you for your support!

Is there a way to make a subscription's auto-renewal fail in sandbox environment? Currently, I see no such options (screenshot)

Hello, Apologies if this has been asked before but I have a website that takes subscriptions and payments through PayPal. It's a platform where authors can sell ebooks and anyone who purchaes an ebook, the money goes pretty much directly from the buyer's PayPal to the seller PayPal through the use of PayPal Multiparty where my platform acts as a third party that takes a fee. I'm currently building a React-Native app for my website and coming close to needing to integrate payment solutions. As far as I'm aware, Apple only allows Apple Pay payments for IAP and subscriptions? How would this work for my model? Can I integrate PayPal into Apple Pay like I do with my website? If not, what's the alternative?

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.
