This worked well for me, additionally using BASIC authentication:

curl -v --proxy '' --basic -u Administrator:password -X POST -H "Content-Type: application/json"
        --data-binary '{"value":"30","type":"Tip 3","targetModule":"Target 3","configurationGroup":null,"name":"Configuration Deneme 3","description":null,"identity":"Configuration Deneme 3","version":0,"systemId":3,"active":true}'

Of course, you should never use BASIC authentication without SSL and a checked certificate.

I ran into this again today, using Cygwin's cURL 7.49.1 for Windows... And when using --data or --data-binary with a JSON argument, cURL got confused and would interpret the {} in the JSON as a URL template. Adding a -g argument to turn off cURL globbing fixed that.
