Share details of post on a wall

I am interested in tracking the user IDs of those who are sharing the wall posts on my fanp开发者_运维技巧age. Does the graph api now support returning the user IDs of the user who have shared the wall post on their wall like I can see who all commented & liked the post?

Any possible workarounds?

yes it's possible you can do through facebook graph api.

get all post with comments + comment user id + liked user id.

these data managed by your own database.
