Get all notifications (like messages, comments etc..)

Hello,

Is there any api in Telligent that can give us info about any type of notification related to a user. for more clearity  i am placing a screen shot below

In above screen shot (yellow rounded part) have some notification for a user 

1.  for read/unread notifications (in above pic there is 2 unread notifications) 

2. for messages.

 here i want  info for  all read and unread notifications and also info for any message. Please suggest any docs of such type of api available in Telligent.

Thanks
