in reply to Re^2: REST::Client does not provide any output (debugging x-authorization)
in thread REST::Client does not provide any output

The actual is "x-appname-Authorization". I removed the appname from the string as it is our application code name which is still under development. Thanks for your time.

Ok, but that still doesn't explain what protocol what rfc that x-authorization header is supposed to follow

X- means non-standard , application specific , it doesn't explain what application, what protocol, what format

I don't know how curl determines this, but I imagine if you turned on more debugging/verbosity in curl you might find out
