We have recently enrolled to the platform integrator program in order to be able to use this API https://developer.apple.com/documentation/applepaywebmerchantregistrationapi to verify our customers' domains for apple pay. We have distributed certifications and the domain association file and have successfully conducted the domain verification call. Consequently, the domain is registered for a given merchant. However, when conducting a payment session request, we receive an error response saying that the domain is not registered. Specific example: We POST to https://apple-pay-gateway.apple.com/paymentservices/registerMerchant with body: { "domainNames": [ "example.com" ], "encryptTo": "platformintegrator.com.example", "partnerInternalMerchantIdentifier": "example", "partnerMerchantName": "example" } and get a 200 response. The apple server successfully conducts the call to the example.com/.well-known/apple-developer-merchantid-domain-association resource. Then the GET request to https://apple-pay-gateway.apple.com/paymentservices/merchant/example lists the domain for this merchant: Response { "domainNames": [ "example.com" ], "partnerMerchantName": "example", "partnerInternalMerchantIdentifier": "example", "partnerMerchantValidationURI": "/.well-known/apple-developer-merchantid-domain-association", "encryptTo": "<hashed merchant id>", "delegatedCommerce": { "enabled": true } } However, when trying to initiate an apple pay payment session here: POST https://apple-pay-gateway.apple.com/paymentservices/paymentSession Body: { "merchantIdentifier": "platformintegrator.com.example", "displayName": "example", "initiative": "web", "initiativeContext": "example.com" } we receive this error response: { "statusMessage": "Payment Services Exception merchantId=<hashed merchant id> not registered for domain=example.com", "statusCode": "400" } Our assumption is that after registering a domain for a merchant the apple pay process should work. We already have a working apple pay implementation with the traditional domain verification process with merchant IDs. We would like to know if we are missing any detail or what is causing this error in our payment process.

Hello, We have been trying to contact the Apple Developer Support for some time now regarding a couple of issues. For a couple of months now we are seeing that we are getting an error when we visit https://developer.apple.com/contact and the topics aren't loaded at all. After seeing the network traffic in the developer tools I see that we get a "Failed to load resource: the server responded with a status of 500 (Internal Server Error)" when making a request to the services/userProfile/ endpoint. The weird part is that the response contains our userProfile just fine. The only thing that I see in the payload that could be an issue is the resultCode that is 0. Has anyone encountered this before or has any idea on what we can do? I don't see an alternative way to contact Apple in order to resolve this issue.
