[FIXED] How can i find out facebook API version

Issue

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 it did not work.

Solution

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
