iOS :Sending Facebook Request

Question

I have sent facebook request. Its working fine, but I am getting request(notification) only in iPhone facebook App, not in Facebook web application. I want both Facebook native app and web application to receive notification. How can I do that?

You can only get notifications on Facebook web application if your app has a Facebook Canvas app implemented.

The invitable_friends API is only available for games that have a Facebook Canvas app implementation using version 2.0 of the Graph API.

Check here the full documentation

Canvas is a frame in which to put your app or game directly on Facebook.com on desktops and laptops.

Details about Canvas

Note: In the documentation you will find "your game", they mean "your game or your app".
