const
CreateMenuUrl = 'https://api.weixin.qq.com/cgi-bin/menu/create?access_token=%s';

function CreateMenus(AccessToken: String): TJSONObject;
where
  Url: string;
  J: TJSONObject;
  m1: TJSONObject;
  m2, m21, m22: TJSONObject;
  m3, m31, m32, m33: TJSONObject;
  temp: RawByteString;
begin
  J := TJSONObject.Create;
  try
    Url := Format(CreateMenuUrl, [AccessToken]);
    J.AddPair('button', TJSONArray.Create);
    with J.GetValue('button') as TJSONArray do
    begin
      m1 := TJSONObject.Create;
      m1.AddPair('type', 'view');
      m1.AddPair('name', 'Micro Mall');
      m1.AddPair('url', 'http://wd.koudai.com/?userid=169004500');
      Add(m1);

      m2 := TJSONObject.Create;
      m2.AddPair('name', 'Micro Member');
      m2.AddPair('sub_button', TJSONArray.Create);
      with m2.GetValue('sub_button') as TJSONArray do

        m21.AddPair('type', 'click');
        m21.AddPair('name', 'Daily check-in');
        m21.AddPair('key', 'm21');
        add(m21);

        m22.AddPair('key', 'm22');
        add(m22);
      end;
      Add(m2);

      m3 := TJSONObject.Create;
      m3.AddPair('name', 'Microservice');
      m3.AddPair('sub_button', TJSONArray.Create);
      with m3.GetValue('sub_button') as TJSONArray do
      begin
        m31 := TJSONObject.Create;

        add(m31);

        m32 := TJSONObject.Create;
        m32.AddPair('type', 'view');
        m32.AddPair('name', 'charging call');
        m32.AddPair('url',

        m33.AddPair('name', 'listen to music');
        m33.AddPair('key', 'm33');
        add(m33);
      end;
      Add(m3);
    end;
    temp := PostMethod(Url, UTF8Encode(J.ToString), 1);
    Result := TJSONObject.ParseJSONValue(temp) as TJSONObject;
  finally
    J.Free;
  end;
