Follow Unfollow functionality

Hi Team,

I am using below rest api for Follow Unfollow functionality.

jQuery.telligent.evolution.put({
url: jQuery.telligent.evolution.site.getBaseUrl() + 'api.ashx/v2/forums/{forumid}/threads/{threadid}/subscriptions.json',
data: {
'threadid': '6',
'IsSubscribed': 'True'
},
success: function(response) {

}
});

from below url.

 https://community.telligent.com/community/10/w/api-documentation/61550/subscribe-forum-thread-rest-endpoint 

can anyone please let me know what will be the flow of follow or unfollow for example. 

  • if someone follow the particular thing then message will go to the user or not that your particular thing has been followed by some one ?
  • if user has updated the particular thing then user who has followed will get notification or any message ?
  • if user deletes the particular thing then user who has followed will get notification or any message ?
  • In which form user will get update regarding the followed item in form of notification, messages or in form of mail ?\

Please provide over all flow if we follow the particular thing.

Thanks.
