title: Can non-game app use FB apprequests dialog in FB v2
body: <p>In FB api v2.0+, can non-game app use apprequests <a href="https://developers.facebook.com/docs/games/requests/v2.2#implementation" rel="nofollow">https://developers.facebook.com/docs/games/requests/v2.2#implementation</a>? I tested that our app which is categorized as shopping app seems to be able to use apprequests without problem when switching to FB v2.1, however on the link of <a href="https://developers.facebook.com/docs/games/requests/v2.2#implementation" rel="nofollow">https://developers.facebook.com/docs/games/requests/v2.2#implementation</a>, it says "Requests are available for games on Canvas, iOS or Android.". Why my test shows apprequests api works for FB v2 for my shopping app, but the documentation says it only work for Game app? </p>
