Not able to access list from SharePoint online site using lists.asmx web service

Hi,

I have to access a SharePoint online list using lists.asmx web service. Refer below code:

QaTest.Lists List = new QaTest.Lists();
            System.Net.NetworkCredential Credentilas = new System.Net.NetworkCredential("SPOLoginName", "SPOPassword");
            List.Url = "https://Test947.sharepoint.com/sites/at/_vti_bin/lists.asmx";
            List.Credentials = Credentilas;
            XmlNode ListItems1 = List.GetList("{CC16E6EE-0686-4115-A786-A37F7622A94B}");

Getting access denied error while accessing it. But, same code is working fine for on premises environment.

So, is there any way to access SharePoint online list using web service??

Thanks,
