I am new to vantiv, as a developer I wanna certify the MX925 device and display sample text like "Hello World".
I try to fire Postman GET with ApplicationID,Token, ID, acceptor ID values from email when i registered.
But response is 500 Internal server error with JSON as follows:
"exceptionMessage": "The request header is missing [tp-application-name]."
Could you help me where I am missing whether I need to send any forms to get certify or is the issue is with public/private keys?
Thanks again in advance.
