I want to use Facebook's Realtime updates feature with my app.

My app is a client app, but as far as I can tell from the documentation I need to make a HTTP POST request to the /APP_ID/subscriptions endpoint which includes a callback_url parameter.

Is this callback url necessary?.

As I am working with windows 8 metro style application I cannot define a callback url for the app because this is client-side code.

Without a callback URL how would Facebook contact you to tell you there are new updates?

Short answer, no, there's no way to receive real-time updates without a callback URL
