Is it possible to change the Response Code when user authorization fails in a datasnap server?

Question

Is it possible to change the HTTP Response Code in my DataSnap (Delphi XE3) server when user authorization fails? Currently it's returning HTTP/1.1 500 Internal Server Error, which can happen in many other scenarios, and doesn't help describe the problem.

Along the same idea, is it possible to change the default Response Body? Currently, it's returning {"error":"USER is not authorized to perform the requested action."}, which is fine, but I'd like to return a custom JSON object if possible.

Thanks for your time!

I ended up executing code that looked like this in TDSAuthenticationManager.OnUserAuthorize

  if valid = false then
  begin
    GetInvocationMetadata.ResponseCode := 403;
    GetInvocationMetadata.ResponseMessage := JSONResponseObject.ToString;
    GetInvocationMetadata.ResponseContent := JSONResponseOjbect.ToString;
  end

It's possible to get the THTTPDSResponse inside a serverclass? Ex:

TServerClass1.EchoString(val: string);
begin
  GetDSResponse.Header.Add('someheader');
end;
