Application activity (user online)?

Question

API

Good evening!
Is it possible to somehow track whether the user is on the site or not without going into the application?
Thank you.
P.S. By sorting out the VKontakte api, I did not find this.

Answer 1

If you want to do something for VKontakte, then you cannot get this information through the API.
Do it crutch: parse the user's page for the inscription "Online" in the right corner.
