Facebook.notifications.send not working with FBJS

I know the notification.send is about to be deprecated but I still wanted to try it out. I'm using javascript on client side and want to send notifications from the client side. I'm using

Facebook.notifications.send('uid','message','user_to_user'

Doesn't return me any results also tried.开发者_开发知识库

Facebook.notifications_send('uid','message','user_to_user')

Any Ideas on where I'm going wrong?

it's not possible to use FBJS with sending notification

in PHP use: $facebook->api_client->notifications_send($uid, 'message', 'user_to_user');

notifications_send is outdate method. you will receive an empty response. check on new ghrap sytem on http://developers.facebook.com/
