I'm implementing Apple Pay in a Flutter iOS app using the pay plugin and Braintree as the payment processor. I have followed all necessary steps as outlined by Apple and community resources (e.g., Medium articles, official Apple Developer documentation), but the Apple Pay button does not appear on a real device. Here's what I've completed: Created an Apple Pay Merchant ID Created and downloaded the Apple Pay Payment Processing Certificate, then uploaded it to Braintree Downloaded the Braintree-signed certificate and confirmed it's active in the Apple Developer portal Added the Merchant ID under Signing & Capabilities in Xcode Enabled Apple Pay capability in Xcode Added the Merchant ID to Info.plist Installed required Flutter packages (e.g., pay) Using a valid Apple Pay payment configuration file in Flutter (see below) Tested on a real iOS device with a valid Apple Pay test card added to Wallet Flutter Payment Configuration (in Dart JSON): json Copy Edit { "provider": "apple_pay", "data": { "merchantIdentifier": "merchant.com.example", "displayName": "My Store", "merchantCapabilities": ["3DS", "debit", "credit"], "supportedNetworks": ["visa", "masterCard", "amex"], "countryCode": "US", "currencyCode": "USD" } } Despite this complete setup, the ApplePayButton widget remains invisible There are no errors in the console. Can you help identify what may be missing or misconfigured at the code or configuration level?

Apple Sandbox is not available in India, also Apple Pay itself is not supported by Indian Banks. How can I still test using Apple Pay sandbox in India? I am trying to add test cards on my iPhone and it fails to add it. It tries to connect to Issuer, which it should not for sandbox Apple Id. Can anyone help how to achieve this?

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?

Apple Pay processed a transaction but the account has insufficient funds. Later the transaction is declined. Is it expected from Apple Pay? Does Apple Pay throws an error if the account has insufficent funds- iOS Swift ? Does anyone know the code to handle this scenario in Swift iOS?

Doc URL: https://developer.apple.com/documentation/applepayontheweb/requesting-an-apple-pay-payment-session How can I send a POST request using PHP, and what certificates are required?

How can I set it as a formal payment environment if I can make the payment now without any deduction?

I'm integrating Apple Pay with PayFort in a Swift iOS application, and I’m currently working on preparing a valid purchase request using Apple Pay, as described in PayFort’s documentation: 🔗 https://docsbeta.payfort.com/docs/api/build/index.html?shell#apple-pay-authorization-purchase-request The documentation outlines the following required parameters: apple_data apple_signature apple_header apple_transactionId apple_ephemeralPublicKey apple_publicKeyHash apple_paymentMethod apple_displayName apple_network apple_type Optional: apple_applicationData I understand these should be derived from the PKPayment object after Apple Pay authorization, but I’m having trouble mapping everything correctly. Here’s what I’m seeing in code: payment.token // Returns something like: <PKPaymentToken: 0x28080ae80; transactionIdentifier: "..."; paymentData: 3780 bytes> payment.token.paymentData // Contains 3780 bytes of encrypted data payment.token.paymentData.base64EncodedString() // Returns a long base64 string, which at first glance seems like it could be used for apple_data, // but PayFort doesn't accept it as-is — so this value appears to be incomplete or incorrectly formatted I can successfully retrieve the following values from payment.token.paymentMethod: apple_displayName apple_network apple_type However, I’m still unsure how to extract or build the following in the format accepted by PayFort: apple_data apple_signature apple_header apple_transactionId apple_ephemeralPublicKey apple_publicKeyHash apple_paymentMethod These may be contained within the paymentData JSON, but I’m not sure how to decode it or if Apple allows decrypting it in a way that matches PayFort’s expected format. How can I correctly extract or build apple_data, apple_signature, and apple_header from the Apple Pay token? Also, how should I handle the decryption or decoding (if necessary) of paymentData to retrieve values like apple_transactionId, apple_ephemeralPublicKey, and apple_publicKeyHash? If anyone has successfully set this up or has example code that bridges Apple Pay and PayFort’s expected request format, it would be super helpful! Thanks in advance 🙏

I'm currently integrating Apple Pay with my payment provider, and I'm encountering a signature validation error during the payment flow. Here's the setup: I’ve verified that my Merchant Certificate is valid, and I'm able to initialize the Apple Pay session without any issues. Also this curl works fine The Payment Processing Certificate was created by my PSP. PSP claims that the payment token signature is invalid during the transaction phase, which prevents payment completion. The parsed signature starts like this 0:d=0 hl=2 l=inf cons: SEQUENCE 2:d=1 hl=2 l= 9 prim: OBJECT :pkcs7-signedData 13:d=1 hl=2 l=inf cons: cont [ 0 ] 15:d=2 hl=2 l=inf cons: SEQUENCE 17:d=3 hl=2 l= 1 prim: INTEGER :01 20:d=3 hl=2 l= 13 cons: SET 22:d=4 hl=2 l= 11 cons: SEQUENCE 24:d=5 hl=2 l= 9 prim: OBJECT :sha256 35:d=3 hl=2 l=inf cons: SEQUENCE 37:d=4 hl=2 l= 9 prim: OBJECT :pkcs7-data 48:d=4 hl=2 l= 0 prim: EOC 50:d=3 hl=2 l=inf cons: cont [ 0 ] 52:d=4 hl=4 l= 995 cons: SEQUENCE 56:d=5 hl=4 l= 904 cons: SEQUENCE 60:d=6 hl=2 l= 3 cons: cont [ 0 ] 62:d=7 hl=2 l= 1 prim: INTEGER :02 65:d=6 hl=2 l= 8 prim: INTEGER :16634C8B0E305717 75:d=6 hl=2 l= 10 cons: SEQUENCE 77:d=7 hl=2 l= 8 prim: OBJECT :ecdsa-with-SHA256 87:d=6 hl=2 l= 122 cons: SEQUENCE 89:d=7 hl=2 l= 46 cons: SET 91:d=8 hl=2 l= 44 cons: SEQUENCE 93:d=9 hl=2 l= 3 prim: OBJECT :commonName 98:d=9 hl=2 l= 37 prim: UTF8STRING :Apple Application Integration CA - G3 I'm looking for guidance on what could be causing this signature failure. Does anyone know what else I can check regarding the merchant or payment processing certificates, private keys, or key usage that might cause Apple Pay signature validation to fail, even if the session initializes successfully? Domains are also verified. Any help or suggestions would be greatly appreciated.

I built a web application using the Apple Pay on the Web Interactive Demo with the Payment Request API, but encountered a few issues: The initiated web Apple Pay interface shows a spinning circle at the bottom and cannot proceed with payment（Bottom display:正在处理）. What could be causing this? How to set up sandbox testing for payments? How to asynchronously and synchronously retrieve payment results (backend code to fetch payment results)? The demo only shows frontend code using await response.complete("success"); for retrieving payment results my demo URL： https://shop.wowseer.com/rsolomakhin/pr/applepay/

我使用Apple Pay on the Web Interactive Demo构建了一个web应用使用的是Payment Request API方式，但是遇到了几个问题： 拉起的web Apple Pay 底部一直转圈圈无法付款，这个是什么问题？ 如何设置sandbox测试付款呢？ 如何异步、同步获取支付结果（后端代码获取支付结果）？demo只有await response.complete("success");前端代码获取支付结果的操作 demo网址: https://shop.wowseer.com/rsolomakhin/pr/applepay/

Hi, We are trying to make the PKAddPaymentPassViewController to show the correct list of devices to where the pass can be added. We have analysed the documentation and we are using the PrimaryAccountIdentifier field which is the field that supposedly controls this behavior but the list of devices presented in the view controller always include one iPhone and one Apple Watch, regardless of where the card has been already added. We are initializing the PKAddPaymentPassRequestConfiguration object with: PKEncryptionScheme PrimaryAccountIdentifier CardholderName PrimaryAccountSuffix LocalizedDescription PaymentNetwork PrimaryAccountIdentifier CardholderName PrimaryAccountSuffix LocalizedDescription We have also verified the configuration in our payment pass processor and everything should be ok. We would like to have some help on achieving the desired flow for Apple Pay, which is to present the PKAddPaymentPassViewController with the correct list of available devices and not the full list. Thank you.

Hello Apple Devs, We’re currently trying to integrate Apple Pay on the web using Apple Pay JS. We've followed the official documentation closely, but we're running into a blocker during the merchantSession validation phase. We successfully retrieved a merchantSession, which looks like this: json { "displayName": "Our Name", "domainName": "https://pay.ourdomain.co", "epochTimestamp": , "expiresAt": ****************, "merchantIdentifier": "", "merchantSessionIdentifier": ", "nonce": "", "operationalAnalyticsIdentifier": our name "t:", "pspId": "", "retries": 0, "signature": "*****************..." } Issue: Shortly after initiating the session, we receive a cancel event with the following info: ApplePayCancelEvent { type: "cancel", sessionError: { code: "unknown", info: {} } } We're unsure what causes the cancellation. There are no clear error messages or hints in the logs to identify what went wrong. What We’ve Checked: The merchantSession is returned successfully from our backend. The domainName matches our frontend domain (https://pay.durdomain.co). The session hasn’t expired when tested. We're using Apple Pay JS APIs as described in the documentation. Help Needed: What can trigger an ApplePayCancelEvent with an "unknown" error code? Any insight or guidance would be deeply appreciated. Thanks in advance!

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.

Hello I'm getting an error when the Apple Pay sheet opens on a third party browser like Chrome when completeShippingMethodSelection is called 'DataCloneError: Failed to execute 'postMessage' on 'Window': #<Object> could not be cloned.' I'm also seeing this warning when the apple pay sheet opens Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://applepay.cdn-apple.com') does not match the recipient window's origin although I also see this warning on https://applepaydemo.apple.com/

I have an app that has been approved by Apple's review team and includes a renewable monthly subscription, which has also been approved. However, when testing the app with a sandbox account on a real device, I am encountering an issue. Within the app, when trying to fetch the subscription using the product ID to display it and allow the user to subscribe, I am unable to retrieve the subscription data, even though I am providing the correct ID and using a sandbox user account on a real device. I would like to request support to understand and resolve this issue. Is there any additional configuration or procedure I should follow to ensure that when fetching the subscription using the product ID, I receive the subscription data to display and allow the user to subscribe?

Hi, we are trying to verify our domain and we uploaded the file to our domain {DOMAIN}/.well-known/apple-developer-merchantid-domain-association.txt and we can access it. But when we want verify the domain in your platform we can't do it and you see the message "Domain verification failed". How can we verified or if we need change something in our side to verify it? thanks!

We are on a .NET ecommerce site hosted on AWS on a windows 2012R2 server. We have apple pay for the web integrated on the site and the certificates (merchant id and apple pay) were set to expire shortly. We created a new merchant id and apple pay cert, however we are now stuck as the new merchant ID certificate doesn't appear to be working although the old one did. Note there have been no code changes. Basically the apple pay process is failing on the merchant validation. Here are the steps we took: Created a CSR in Keychain Access Generated a Merchant ID cert in the Apple Developer account with that CSR. Imported the Merchant ID cert back into Keychain Access and exported as a p12 file the cert and the private key used to generate the CSR. Imported the p12 file into Windows 2012 R2. I can see in our debugging that the new certificate is being loaded but a SSL/TSL connection couldn't be made. So it seems there is an issue with the cert. Has anyone encountered this? I'm out of ideas at this point and under a lot of pressure from management to fix what was supposed to be a routine maintenance issue. If anyone has any ideas, that would be greatly appreciated.

Dear Apple team and developers, We integrated Apple Pay E-Commerce on our system and made successful transaction at January using following certificates. Merchant Identity Certificate (generated from our Apple developer account) Payment Processing Certificate (generated from our Apple developer account) Payment Session Server Certificate (used following command and generated from apple-pay-gateway-cert.apple.com:443 test URL) Command: openssl s_client -connect apple-pay-gateway-cert.apple.com:443 -key MIC_priv.key -cert MIC_merchant_id.pem -showcerts | openssl x509 -outform DER &gt; apay_ident_trusted_cert_test.der Root CA G3 (Downloaded “Apple Root CA – G3 Root” from https://www.apple.com/certificateauthority/ ) But at this month, we got new certificate problem (please check following) when we try to execute Apple Pay E-Commerce transaction. Certificate 'C=US,O=Apple Inc.,OU=Apple Certification Authority,CN=Apple Application Integration CA - G3' is not valid Certificate. What is this certificate? And Where can I download or generate this certificate from? Could you please advise/give us good information for this certificate problem? Best Regards, Bilguun Enkhbaatar
