Am I able to return a record from an endpoint

[Rohit_Nz (Gupta Rohit)]

Continuing the discussion from Parse JSON returned from XData back into an Object:

@wlandgraf

A "Delphi" (*) TMyObject object has several meta information inside it and it's not very safe to case a JS object to it.

But if you declare a class with external keyword, you can simply case the parsed object directly, Pas2JS allows that:

var
  JSObj: TJSObject;
  MyObj: TMyObject;
begin
  JSObj := JS.ToObject(TJSJSON.parse(JsonString));
  MyObj := TMyObject(JSObj)
end;

(*) Delphi between quotes because it's Pas2JS, not Delphi, strictly speaking.

This is at the Client. What do I do at the Server end, in my endpoint code?

That is just a regular XData endpoint (service operation) as explained in the documentation and all the examples around that use service operations:

Service Operations | TMS XData documentation

Actually that is valid for early all XData endpoints, all of them return JSON unless you specify otherwise.
