when I'm making a call to "apple-pay-gateway-cert.apple.com/paymentservices/startSession"
I'm getting an error
{"statusMessage": "Payment Services Exception merchantId=XXXXXX-LONG_STRING-XXXX not registered for service", "statusCode": "417"}
Has anyone else faced this issue and can you please suggest what could be the reason for it?
I've exhausted myself looking for an answer for this
