How to post to fan page (mine) as app from site
===

I have an app and I want the app to post to my fan page.  I have an access token as the app:
  

    $r = curl('https://graph.facebook.com/oauth/access_token?client_id='.fbid.'&client_secret='.fbappsecret.'&grant_type=client_credentials');
    $apptok = str_replace('access_token=','',$r);
which is good, as I am able to get the app info:

    $r = curl('https://graph.facebook.com/app?access_token='.$apptok );

I am trying to post as app with:

    	$fbpost['access_token'] = $apptok;
	$fbpost['message']      = $messageRa['message']; // 'here's the msg'
	$fbpost['link']         = $messageRa['link']; //$site;
	$fbpost['description']  = $messageRa['description']; //'desciptionss';
	$fbpost['caption']      = $messageRa['caption']; //'captions';
	$fbpost['picture']      = $messageRa['picture']; //fbhomeimg;
			
	return  $facebook->api('/'.$fbpageid.'/feed', 'POST', $fbpost);

I'm getting (#200) The user hasn't authorized the application to perform this action".  Do I need to get a different app token? I cant find any more info on grant_type = client_credentials, so I dont know if i need to ask it for more cred.
