How to create a case screenning by Word-Check API?

Hello.

I'm brasilian and I got a manual of Word-Ckeck API from Thomson Reuters.

I'm trying to call the API to create a case, but I'm facing difficulties.

When I call the API, the error "Could not get any response" is returned.

Where am I going wrong?

Best regasds.
