I have implemented facebook notification api.
this is it.
$notiData = array('href'=> 'https://apps.facebook.com/',
'access_token'=> $app_token,
'template'=> 'test' );
$noti = $facebook->api('/userId/notifications','POST',$notiData);
my problem is how to send a notification to multiple/ all app users at once? how to implement RECIPIENT'S IDS?
I tried like this
$noti = $facebook->api('/10343603789032,123404256614081/notifications','POST',$notiData);
above method didn't work.
