Creating a facebook application

Hi I created a desktop application. I was wondering what I should put for my Canvas Callback URL. I tried to define it as local (http://localhost:8084) but it doesnt accept it.

I need it to get the session using http://www.facebook.com/login.php?api_key=YOUR_API_KEY&v=1.0

Thanks!

Your canvas callback URL has to be an address that Facebook can actually fetch data from. That is not localhost, since as the name implies that is local to you.

Read the following: http://wiki.developers.facebook.com/index.php/Canvas_Callback_URL#How_It_Works

Your canvas page URL is http://apps.facebook.com/foobar/
Your canvas callback URL is http://www.foobar.com/yourapp/
[...etc]

Putting localhost as the canvas callback url is like buying something online and filling the shipping address as "my house".

For some basic information on how a Facebook application works, this is a good reading material:
