I just realised that you might be saying here "I want JSON output if the
client sends a request from postman, and I want HTML output if it's from a
browser, but in both cases the URL is the same".
To achieve that your CGI script simply needs to look at the User-Agent in the
incoming request, and send back the appropriate format depending on whether
it's postman or a browser.
I do not know offhand what the User-Agent string is for postman, but it can't
be hard to find out.
