Can a page tab post to a user's wall?

Question

I have a Facebook application used as a tab in a fan page, that displays different information depending on whether tha user is a fan of that page or not.

Now I've been asked to have it post a message to a user's wall if they perform certain action (follow a link or whatever), and so far I haven't found a way to do that. All the documentation I have found refers to stand alone apps, and I've even seen it suggested (in the FB forums) that you can't get the auth token from an app.

So, i still think it can be done, but how?

Answer 1

If a user has authorized your app, you can post to her wall using the PHP SDK. See the PHP SDK api documentation for examples.

Answer 2

All apps have to be iframe apps now, so loading the JS sdk should be fine.

You have to get permissions first ->

http://developers.facebook.com/docs/authentication/#applogin

Then you can post using php with what Dhiren said, or, post with the fb.api function with JS -> http://developers.facebook.com/docs/reference/javascript/FB.api/

Let me know if you need an example script.
