Count for social follower for a site collection / tenent

Hi Community Members,

We are trying to get the count of users that has follow a particular site collection on a tenant. We are tying to use the SharePoint rest services "_api/social.following/" to achieve this and still struggling with this. We are able to do the same with current user but we need this for all users means how many users on a site who has follow site as rss.

I have gone through the TechNet article but this is works correctly for current user, I want to show details of all users on my Tenant.

Thanks

VJ
