How can I retrieve the check-in object from foursquare by querying with a checkin id?

Question

I have obtained the 4sq checkin id from twitter streaming api and I want to get the details of the checkin such as userid, time, venueid etc.

However, when I check the 4sq api, I find that the related endpoint requires an acting user. So can anybody suggest what could be an alternative way to get this information? (especially user_id)

Thanks!!
