 <p>You cannot programatically fill in login information, that is against the Facebook terms and conditions. You can, however, authenticate as an application as opposed to a user. Use the following method:</p> <pre><code>Make a GET request to: https://graph.facebook.com/oauth/access_token?grant_type=client_credentials&amp;client_id=CLIENT_ID&amp;client_secret=CLIENT_SECRET Facebook returns: access_token=SOME_TOKEN Use this token as your access token and it should allow you to access the group. I have tested this with my application and can confirm it works. You request the wall information via the request: https://graph.facebook.com/GROUP_ID/feed?access_token=SOME_TOKEN </code></pre> <p>This will not pop up any login screens as you are not required to be logged in to view a public group. Ensure your privacy settings are public for the group as well.</p>
