How To Post A Message On The User Wall Using Facebook Graph API

Hi All!

I was going through this tutorial (http://www.masteringapi.com/tutorials/how-to-post-a-message-on-the-user-wall-using-facebook-graph-api/33/) and was trying to figure out how do I post a message on my friend’s wall using the FB Graph API.

I was able to post messages for friends who have authorized my App (clicked on teh ALLOW button of my app) but I am not able to post on my friend’s wall who have NOT allowed my app.

So my questions are:

  1. Is it possible to post a message on a friend’s wall who have not authorized my app?

  2. If yes, how do I do this?

  3. If no, then is there any alternate way? Actually I am trying to implement a feature in my application that will allow the users to invite their friends.

Please suggest
