Module provided in the request is not supported

I'm trying to send a post to this url: http://mgfsrv215/sdpapi/change/

with the follow query:

TECHNICIAN_KEY = <my key>
OPERATION_NAME = "ADD"

I'm following this doc:

But I'm receiving this error



{"operation"=>{"result"=>{"status"=>"Failed", "message"=>"Module provided in the request is not supported."}, "name"=>"POST"}}

my service desk version is:
Version         : 9.0 Build 9006
Latest Version : 9.0 Build 9006 

this is supported this version?

                  New to ADSelfService Plus?
