Send Facebook Notifications

I am working on "courses 2.0" application development team.This is one of the best application in facebook.

I want to send facebook notification to all our application user at once. I have all user id's as a string format separated by commas. I am able to send the notifications to these users but some times some notifications are not sent.

Is there any limit for the n开发者_运维知识库otifications per day? If so , can we over come this limit? please help me in this task

Thanks Gopal

Yes there are limit per day and you can do nothing about it as far as i know. It is the policy of facebook to limit those to a certain number on daily basis.

See your allocations:
