var
success: Integer;
http: TChilkatHttp;
url: WideString;
contentType: WideString;
json: TChilkatJsonObject;
responseObj: IChilkatHttpResponse;
responseOut: TChilkatHttpResponse;

success := 0;

http := TChilkatHttp.Create(Self);

url := 'https://example.com/something';
contentType := 'application/json';
json := TChilkatJsonObject.Create(Self);
json.LoadFile('C:/temp/requestBody.json');

//  ------------------------------------------------------------------------
//  The PostJson3 method is deprecated:

responseObj := http.PostJson3(url,contentType,json.ControlInterface);
if (http.LastMethodSuccess = 0) then
  begin
    Memo1.Lines.Add(http.LastErrorText);
    Exit;
  end;

//  ...
//  ...

//  ------------------------------------------------------------------------
//  Do the equivalent using HttpJson.
//  Your application creates a new, empty HttpResponse object which is passed 
//  in the last argument and filled upon success.

responseOut := TChilkatHttpResponse.Create(Self);
success := http.HttpJson('POST',url,json.ControlInterface,contentType,responseOut.ControlInterface);
if (success = 0) then
  begin
