Apple Pay fractional amounts for RSD
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?

Twitch Like Subscriptions - Many-to-Many
Hi guys, We are trying to implement a solution that would allow users to subscribe to other users in our app. The system should work the same way as Twitch's subscription model works. Users should be able to subscribe to anyone and each subscription should have different tiers. From what we were able to gather, users cannot have multiples of the same subscription on applestoreconnect. Meaning that we would probably need to make a custom subscription per every user? Here we have also learned that there is a limit of 10 000 types of subscriptions and that it is not possible to dynamically create/delete them for users. (correct me if I am wrong) Is there a solution for handling this type of a scenario? Appreciate all answers.

Apple Pay JS v3 in Angular: postMessage origin mismatch and onpaymentauthorized never fires
Description: I’m integrating Apple Pay JS (version 3) into an Angular application. Here are the key details: Environment: Angular (latest) Apple Pay JS v3 Chrome (confirmed window.ApplePaySession is available) application region is in US. I'm in Taiwan and using my iPhone Taiwan account to scan the QR Code/ Implemented Handlers: onvalidatemerchant onpaymentmethodselected onpaymentauthorized oncancel Observed Behavior: When I click the Apple Pay button, the console logs: Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://applepay.cdn-apple.com') does not match the recipient window's origin ('https://{our-domain-name}') Despite this, the QR code still appears. Scanning the QR code with an iPhone 13 Pro running iOS 18.4.1 brings up the Apple Pay sheet with the correct amount, but payment never completes. In the browser, none of my Angular event handlers fire except oncancel. Questions: What causes the postMessage origin mismatch with Apple’s CDN frame, and how should my application handle it? Why doesn’t onpaymentauthorized ever fire, and how can I complete the payment flow so that session.completePayment() succeeds? Any guidance or sample code snippets for a proper merchant-validation and payment-completion sequence in this setup would be greatly appreciated. my code onApplePayButtonClicked() { if (!ApplePaySession) { console.error('[ApplePay] ApplePaySession is not supported'); return; } // Define ApplePayPaymentRequest const request : ApplePayJS.ApplePayPaymentRequest = { countryCode: this.currencyCode, currencyCode: Constants.CountryCodeUS, merchantCapabilities: this.merchantCapabilities, supportedNetworks: this.supportedNetworks, total: { label: this.label, type: "final" as ApplePayJS.ApplePayLineItemType, amount: this.orderAmount.toString(), }, }; // Create ApplePaySession const session = new ApplePaySession(3, request); session.onvalidatemerchant = async event => { console.info('[ApplePay] onvalidatemerchant', event); try { const merchantSession = await fetch(`${this.paymentUrl}/api/applepay/validatemerchant`, { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ PKeyCompany: this.paymentAppleMerchantId, ValidationUrl: event.validationURL }) }).then((r) => r.json()); session.completeMerchantValidation(merchantSession); } catch (error) { console.error('[ApplePay] onvalidatemerchant MerchantValidation error', error); session.abort(); } }; session.onpaymentauthorized = (event) => { console.info('[ApplePay] paymentauthorized', event); const token = event.payment.token; this.paymentTokenEmitted.emit({ token: JSON.stringify(token), paymentType: PaymentOptionType.ApplePay }); session.completePayment(ApplePaySession.STATUS_SUCCESS); }; session.onpaymentmethodselected = (event) => { console.info('[ApplePay] paymentmethodselected', event); const update: ApplePayJS.ApplePayPaymentMethodUpdate = { newTotal: request.total }; session.completePaymentMethodSelection(update); }; session.oncancel = (event) => { console.error('[ApplePay] oncancel', event); this.errorEmitted.emit({ error: 'Apple Pay cancel' }); }; session.begin(); }

Apple Pay pre-auth: how to not show hold amount (gas-station style) for usage-based rentals?
We’re building a usage-based rental flow. The final charge is only known after the session ends (like gas pumps). We want the same Apple Pay UX that gas stations like at a gas station has: the user does not see a pre-authorization amount up front; they only see “approved” and later the final posted amount on the statement. What we observe (gas stations / desired UX) When paying at gas station with Apple Pay (card-present), the user confirms their card (double-tap) but no pre-auth amount is shown in Wallet/notification UI. The small notification is from the bank (not the merchant) and shows only bank + merchant name, no total. After fueling ends, the final amount appears on the statement from the merchant. What happens in our flow (current behavior) Platform: Apple Pay via Stripe (Apple Pay on the Web with QR → mobile Safari Wallet sheet). When a user confirms payment, the pre-authorization amount is shown immediately to the user (appears like a charge from the user’s perspective). We want to avoid showing that amount, matching the pay-at-pump experience.

Shortcuts | Transaction Automation | IOS 18
Hello forum, Hope all is great! I have a shortcut automation which uses the transaction trigger. Since updating to ios 18 the transaction trigger does not work anymore. Whenever a transaction is done, the “Running your automation” notification does not show up and the automation does not work. To share with you the steps I’ve done so far: 1.Remove the automation and do it again 2.Remove the card from apple pay 3. Delete and install again the shortcut app 4. Turned on and off the phone I can confirm the automation works on my other iPhone with the latest version of IOS 17. Would really appreciate if anyone has any insights about that, or if this happened to you as well. Cheers! Dorin

domainName missing from create payment sessions request in sandbox
We have been using ApplePay on the web for years, but we are running into a problem since today in sandbox where domainName is missing from the create payment sessions request. We haven't changed anything related to this request any time recently. Static payment sessions url being hit in sandbox: https://apple-pay-gateway-cert.apple.com/paymentservices/paymentSession request format: "merchantIdentifier": "merchant.com.identifier", "displayName": "Test Store", "initiative": "web", "initiativeContext": "test.example.com", "domainName": "test.example.com" response format: { "epochTimestamp": 1763533367972, "expiresAt": 1763536967972, "merchantSessionIdentifier": "<merchantSessionIdentifier>", "nonce": "<nonce>", "merchantIdentifier": "<merchantIdentifier>", "displayName": "Test Store", "signature": "<signature>", "initiative": "web", "initiativeContext": "test.example.com", "signedFields": [ "merchantIdentifier", "merchantSessionIdentifier", "initiative", "initiativeContext", "displayName", "nonce" ], "operationalAnalyticsIdentifier": "Test Store:<identifier>", "retries": 0, "pspId": "<pspId>" } Production create session request to https://apple-pay-gateway.apple.com/paymentservices/paymentSession is behaving as expected, sending the following fields as response: epochTimestamp, expiresAt, merchantSessionIdentifier, nonce, merchantIdentifier, domainName, displayName, signature, operationalAnalyticsIdentifier, retries, pspId Claude seems to suggest this is a response when Messages for Business is enabled, but this ApplePay Payment Processing merchant is only configured for Apple Pay on the Web. Any ideas or pointers to check for? We are worried this will spill over in production as well, which will break our ApplePay integration. Thanks in advance!

How to Adding credit or debit cards from a card issuer’s website
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!

Apple Pay Fails in Chrome
I'm implementing Apple Pay for our application via the Apple Pay JS API, and everything works as expected when initiating a session from a Safari browser. However, when attempting to start a session in a non-Safari browser (Chrome in this case), I see the following behavior: The "Scan Code with iPhone" popup appears I scan the code with my device (9th gen iPad running iPadOS 18.5 if that matters) The Apple Pay view does not appear on the device, and the "Scan Code" popup closes on the browser without any further information given. I can see the messages being passed in the network tab, with the final message being a "getPaymentRequestResponse" message appearing at the time the code is scanned. I suspect merchant validation is failing since that should be the next step, but that's just an educated guess at this point. I would appreciate any help getting this issue resolved.

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.

Error Domain=PKPassKitErrorDomain Code=2
This error occurs in Apple Pay Wallet In-App Provisioning Flow for Credit / Debit Cards When the data received from the PNO (Visa) is passed to PKAddPaymentPassRequest this error is seen in addPaymentPassViewController, in the finalize stage. Docs provide no clue as to what could be wrong. iOS 18.2.1 XCode 15.2 Error description mentions "unsupportedVersionError" Is the pass version not supported? Is the wallet version not supported? Is it an app implementation error or error in the data received from the PNO?

cant add Apple Pay Mastercard test card
I recently created a Sandbox account and successfully added an Apple Pay test MasterCard to the sandbox Wallet to run a test. Yesterday, I created a different account and tried to add a MasterCard on another device, but I received a "Card device limit" error. I then deleted the card from the original device (where it had been successfully added) and tried to re-add it, but this device also failed. I was able to confirm that a JCB card can be added, but I need to test with MasterCard. What should I do to resolve this?

Apple Pay In-App Provisioning – Apple server failure when adding a card
During Apple Pay in-app provisioning (EV_ECC_v2), our iOS app successfully obtains the issuer provisioning certificates and generates cryptographic material. The flow fails when Apple posts the card blob to Apple’s broker (card creation step), returning HTTP 500 from .../broker/v4/devices/{SEID}/cards. Steps: Call issuerProvisioningCertificates?encryptionVersion=EV_ECC_v2 → 200 OK; returns ECC leaf + Apple Root CA chain; nonce=2a831be4. 2. Build {encryptedCardData, activationData, ephemeralPublicKey} 3. POST /broker/v4/devices/{SEID}/cards Expected: 200 OK on /broker/v4/devices/{SEID}/cards, or 5xx with a descriptive error if payload/cryptography is invalid. Observed: 500 Internal Server Error from Apple broker on /cards (labeled “eligibility” in PassKit logs), causing a terminal failure in Wallet UI.
