Yes it seems that the name/country data would be included in the content editor so you don't need name/country parameters.
There is a JSON request example in https://support.smartbear.com/readyapi/docs/projects/ui/request/request/vertical/rest.html
The Raw panel is also useful to see the actual request that was sent

Authorization can be different for any request

Thank you both for your comments. I found the RAW panel to be quite useful while testing.
I've now managed to setup and test the two REST services with a JSON Request, returning a JSON Response.
