I am trying to determine if it is possible to get a list of Facebook users and IDs (via JSON I assume) that have checked in to a place/page.
Is this even possible? Do you need an access token from each user account to access this information? I found Facebook's documentation to be less than helpful...any help will be much appreciated!
You can query the FQL checkin
table but at most (based on the permissions granted) you'll get the user's & her friends' checkins.
