Hello, We are experiencing an issue with Apple Pay integration in our application. We are using WKWebView to handle various payment methods, but we are unable to complete payments via Apple Pay. Upon debugging the WKWebView, we received the following error message: "400 No required SSL certificate was sent" when attempting to process the payment. Currently, we are using a Let's Encrypt SSL certificate. Could you please confirm whether this certificate is suitable for Apple Pay, or if we should be using a different SSL certificate?

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?

Hi, When I try to add a card to wallet, I get this PKPassKitErrorDomain Code=2 error from my logs, and from the SysDiagnose, I get some more detailed error log Error details: Date: December 15, 2025 Time: 15:16 UTC Request URL: https://nc-pod9-smp-device.apple.com:443/broker/v4/devices/041B4183BA1490022104102123315131EBFE2BE7… Response: HTTP Status: 500 – Internal Server Error Time profile: 0.505452 seconds Response headers: Server: Apple Content-Type: text/html X-Content-Type-Options: nosniffStrict-Transport-Security: max-age=31536000; includeSubdomainsDate: Mon, 15 Dec 2025 15:16:59 GMT X-Frame-Options: SAMEORIGIN X-XSS-Protection: 1; mode=blockCross-Origin-Opener-Policy: same-origin Content-Length: 170 Connection: close Response body: Anyone have faced this problem before?

Hello we are trying to renew our certificates. We are trying to extend the dates of verified domains following the docs https://developer.apple.com/documentation/applepayontheweb/maintaining-your-environment#Renew-Your-Domain-Verification and configure our server with https://developer.apple.com/documentation/ApplePayontheWeb/setting-up-your-server We've downloaded the apple-developer-merchantid-domain-association.txt and update it on their respective locations, click 'ok' button but we get redirected to the main page of the information of the merchant, and it shows the domains without the extending period of time. No popup showing what has failed or what could be the reason of this error, we only get a redirection to the main page.

To perform the integration, it must be done under the same domain that has been validated. Is it not possible to do it in a local environment? Could that be the reason why I can't display the button or complete the validation with the API?

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!

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

Hi, To ensure the issue is not caused by an error within your app or web service request, please review the Apple Pay Merchant Integration Guide. Additionally, please review the following technotes on Apple Pay: TN3173: Troubleshooting issues with your Apple Pay merchant identifier configuration TN3174: Diagnosing issues with the Apple Pay payment sheet on your website TN3175: Diagnosing issues with displaying the Apple Pay button on your website TN3176: Troubleshooting Apple Pay payment processing issues TN3206: Updating Apple Pay certificates If the resources above don’t help identify the cause of the error, please provide more information about your app or web services to get started. To prevent sending sensitive credentials in plain text, create a report in Feedback Assistant to share the details requested below. Additionally, if the error is something we need to investigate further, the appropriate engineering teams also have access to the same information and can communicate with you directly within Feedback Assistant for more information, as needed. Please follow the instructions below to submit your report. For issues occurring with your native app or web service, perform the following steps: Install the Apple Pay profile on your iOS or watchOS device. If the issue occurs on Mac, continue to Step 2. Reproduce the issue and make a note of the timestamp when the issue occurred, while optionally capturing screenshots or video. Gather a sysdiagnose on the same iOS or watchOS device, or on macOS. Create a Feedback Assistant report with the following information: The serial number of the device. For iOS and watchOS: Open Settings > General > About > Serial Number (tap and hold to copy). For macOS: Open the Apple () menu > About This Mac > Serial Number. The SEID (Secure Element Identifier) of the device, represented as a HEX encoded string. For iOS and watchOS: open Settings > General > About > SEID (tap and hold to copy). For macOS: Open the Apple () menu > About This Mac > System Report > NVMExpress > Serial Number. The sysdiagnose gathered after reproducing the issue. The timestamp of when the issue was reproduced. Screenshots or videos of errors and unexpected behaviors (optional). Important: From the logs gathered above, you should be able to determine the cause of the failure from PassbookUIService, PassKit or PassKitCore, and by filtering for your SEID or merchant domain in the Safari Web Inspector. See Inspecting Safari on macOS to learn more. Submitting your feedback Before you submit to Feedback Assistant, please confirm the requested information above is included in your feedback. Failure to provide the requested information will only delay my investigation into the reported issue within your Apple Pay website. After your submission to Feedback Assistant is complete, please respond in your existing Developer Forums post with the Feedback ID. Once received, I can begin my investigation and determine if this issue is caused by an error within your web implementation, a configuration issue within your developer account, or an underlying system bug.

Hi, I am the developer of this app and I was shared this receipt which strangely does not list my name as the merchant but instead says "The flow network" as you can see below: What is going on?

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?

Bank Accounts details are outdated and status is stack on processing with error: "Your banking updates are processing, and you should see the changes in 24 hours. You won't be able to make any additional updates until then." This is now stack for a few years since we activated a previous Apple developer account. we must change banking details as it holds up development of an app with in-app purchases. Finance department has been contacted and they do not answer What shall we do? senior support staff keep referring to finance department and is not helping

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/

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

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?

Hi, We have app in which we take donations from people and send to non-profit organisations. I have read that Apple Pay can be integrated on non profit platforms to take donations, but we are middle man, we are not non profit .. we take donations, cut our platform fees and then sent to donations to non profit orgs. My question is can we integrate Apple Pay in our iOS app to take donations from apple? as we have integrated Apple Pay on the web.

We are looking for sample payload for merchant registration API. We have tried to test the api and getting an error. Request: curl --location 'https://apple-pay-gateway-cert.apple.com/paymentservices/registerMerchant' --header 'Content-Type: application/json' --data '{ "domainNames": "https://checkout.dev.sandbox-netvalve.com", "encryptTo": "platformintegrator.com.netvalve.uat", "partnerInternalMerchantIdentifier": "merchant.test.netvalve", "partnerMerchantName": "Test" }' Response: { "statusMessage": "Payment Services Exception invalid or Malformed Json Received", "statusCode": "400" }

We have finished integrating Apple Pay in our app and our payment processor is requiring us to send the 3dSecure version used for apple pay (2.1,2.2,2.3,etc.). I believe this only applies to mastercard but would appreciate if anyone has run into something similar and what you specified. I have not been able to find anything in Apple's documentation specifying the version that is used.

We are having trouble trying to renew our Apple Pay Merchant Identity Certificate. We can create the CSR file and add to the developer portal. We then convert this to a .pem and then a .p12. When we test the certificate in Postman however, we see the following error: "statusMessage": "Payment Services Exception pspId=xxxx unauthorized to process transactions on behalf of merchantId=xxxx reason=xxxx is not a registered merchant in WWDR and isn't properly authorized via Mass Enablement, either.", "statusCode": "417" We are sending the following POST request to 'https://apple-pay-gateway.apple.com/paymentservices/paymentSession': {"merchantIdentifier": "merchant.com.xxxx.applepaytest", "domainName": "beta-xxxx.com", "displayName": "beta-xxxx.com"} Anyone got any ideas what the issue may be? In the meantime I will look at completing our domain verification as that is also due soon and we thought it may possibly have something to do with the certificate issues we are seeing.

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.

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.
