I'm fetching a group's feed https://graph.facebook.com/my_group/feed, but it completely ommits polls and links posted in group. Is there a way to get polls along with other posts?
They just announced this is available on their blog.To get them, issue an HTTP GET request to the USER_ID/questions endpoint with the user_questions or friends_questions permissions.
It is not available yet. See here
they also just announced that you can create questions now via the API.
