Is it possible to get all user id's who have shared a specific post, through graph api or any other resource?

Question

I am looking for a way to record user id's of a public post for a brand. If there are any resources available, any help would be appreciated.

Retrieving share data with FB API doesn't seem to be officialy supported by Facebook, but you can retrieve posts shares with Graph API, just do the following:

• Get the ID of your post (eg. /me/posts query)
• Split the ID on underscore character and get the second part (first part indentifies posts author)
• Query the shares: [id_2nd_part]/sharedposts

Note that since it's not officialy supported it may stop working at some point in the future

You can test it with Graph explorer - to get shared posts you need read_stream permissions on your access token if I'm not mistaken
