I am trying to connect to the First Data Payeezy Gateway Search and Reporting API:
Every time i attempt to connect (either in code or using a tool such as Postman), i am getting 404 errors (Unauthorized).
I am specifying the username and password of a Merchant role user (valid password, not expired) in the header and submitting a GET request, and from what i can tell i shouldn't need to pass any other parameters because it should use default values for everything else.
We log in and manage our accounts (live and demo) through the global gateway (https://demo.globalgatewaye4.firstdata.com), which seems to be set up differently than the Payeezy Developers site (https://developer.payeezy.com), do i need to have both and link them somehow?
Is there anything else that i should look at to get this to work?
