How do you get data for a technician or supportgroup with the REST API

I have managed to get all the technicians with:
 
 
and all the support groups with
 
 
It should be somthing like this
 
 
and
 
 
but I get
 
<operation name="GET_ALL">
      <result>
            <status>
                  Failed
            </status>
            <message>
                  Error when validating URL - Invalid URL for the requested operation.
            </message>
      </result>
</operation>
So it probably means that some xml is needed in INPUT_DATA= but what xml?
