Hello, Please help. We have been experiencing what appears to be a TLS handshake error in our Apple Pay merchant validation requests (2-way TLS) since June 25, 2025. We are aware of the encryption algorithm changes made in February 2025, and our system was functioning correctly at that time. However, the error started occurring suddenly and only recently. Could you please clarify the following points? Have there been any changes to the TLS configuration (cipher suites, certificates, protocol versions, etc.) on the Apple Pay server side since June 2025? Have there been any updates to the specifications or recommended settings for merchant validation requests? Is there any way to contact Apple for technical support regarding this issue other than through the Developer Forums? Our Merchant Identity Certificate has already been renewed and is confirmed to be valid.

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 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.

We have an Apple Pay account and have successfully created and verified the payment processing certificate in our Apple Developer account. When initiating an Apple Pay payment, the Apple session is created successfully with the correct data return from api , but it is not accepted with the error: “Payment not completed.” The issue occurs even though the merchant validation step works without errors. Our websites where this is happening are: https://magicdeliver.com/ https://www.pulsarmodular.com/ Could you please help us identify the cause of the issue and guide us on resolving it?

I am attempting to verify my domain https://technoq.genesistechnologies.tech for use with Apple Pay Merchant ID. However, when I attempt verification, the process fails with the message: “Domain verification failed.” Unfortunately, no additional details are provided. I have already completed the following steps: Downloaded the verification file apple-developer-merchantid-domain-association.txt. Placed it in the .well-known directory as instructed. Confirmed that it is publicly accessible at: https://technoq.genesistechnologies.tech/.well-known/apple-developer-merchantid-domain-association.txt Verified that a valid SSL certificate is configured for the domain. Could you please advise on why the verification might be failing and what additional steps I should take to resolve this issue?
