I need to find when my gmail contact (specified or any contact) login to Hangout/gtalk. I'm trying to do this using google apps script. I looked google apps script to find-out way to do this. but unable to find.
What i'm trying to do is, when my gmail contact (specified or any contact) login to Hangout/gtalk, identified that contact is online and make some google spreadsheet entry.
Is there any way to achieve this ?
It is not possible (and let's hope it will never be:-) to get that information using Google Apps Script.
