问题
I have an app id and secret of a facebook app. But i am not owner, how can I find out its app version?
I tried to go through fb graph api document but not lucky.
Thank in advanced!

According to a somewhat relatable FAQ, you can check the facebook-api-version header in the response to determine the API version that had been used to process the request.
Currently (as of December 26, 2015), the oldest active version is 2.0, so any unversioned calls will use the 2.0 API (until August 2016). The changelog can be found here
