pusher realtime user online status through webhooks <p>I am working on an android app where I have done some realtime applications using pusher. I read about pusher webhooks and I couldn't quite understand the concept when I read it <a href="https://pusher.com/docs/webhooks" rel="nofollow">Here </a>. I want to implement the online status to my contacts and I read about it that it can be done with webhooks <a href="https://support.pusher.com/hc/en-us/articles/204113596-Showing-who-s-online-with-a-large-number-of-users" rel="nofollow">here</a>. Please can anyone explain the concept and usage of webhooks and how can I implement online status using it.</p>
