I am trying in the sandbox environment and trying to pay through developer pay api. It works for sample visa card number:
4111111111111111
But when tried to test using a sample master card number:
5500000000000004
I am getting this error.
{ "paymentId":"7PK2F125NK5BY", "result":"DECLINED", "failureMessage":"SERV NOT ALLOWED: Card type cannot be processed on your merchant proc essing account. Ask for another form of payment. Contact support if you believe this to be incorrect." }
What does this error refer to?
