Update WebClip : Execution of request failed

[Alaeddine GALLAS]

Hi, I'am new with the API ! I'am trying to build some console app to auto setting emails for my domain !

I add our domain to google app and link it with google server !

( So I'm able to receive and send mail )

I tried to do one think : Disable WebClip using this Code !

class Program

    {

        static void Main(string[] args)

        {

            GoogleMailSettingsService service = new GoogleMailSettingsService("hypradev.com", "HypraDev");

            service.setUserCredentials("alaeddin...@hypradev.com", "********");

            try

            {

                service.UpdateWebclip("alaeddine.gallas", "false");

            }

            catch (Exception ex)

            {

                Console.WriteLine(ex.Message);

            }

            Console.ReadLine();

        }

}

Console output :

Execution of request failed: https://apps-apis.google.com/a/feeds/emailsettings/2.0/hypradev.com/alaeddine.gallas/webclip

I tried also to retrieve labels but it throw me the same exception !

Did I miss something ? Did I have to enable something in the domain management portal ?

What I have to do to make thins code run ?
