how to use FB.Connect.StreamPublish

from the scarcely documented FB api, I have thus far learned that I need to do the following to get the StreamPublish working:

I am making an iframe app

1. setup xd_receiver.htm. DONE.
2. put the FeatureLoader.js.php at the top of the body tag. DONE.
3. configure the api key and xd_receiver.htm. DONE.
4. configure the connect callback URL. NOT DONE -> what URL should I specify here?

I am unable to use the function. i have a specific link which shuld call for the FB.Connect.StreamPublish function.

can someone please explain the working o开发者_StackOverflowf this by some example?

Check out this page for complete instructions on setting up Stream Publishing for iFrame apps (or Connect pages) using FB.Connect.streamPublish():

In the facebook application settings, the description is:

Your Connect site's main URL.

And that is exactly what it is, the main URL for the site where your app resides.

If your app would've been a canvas app, you could use the FBJS function FB.streamPublish, but in an iframe app you will have to use the FB.Connect.StreamPublish.

It seems that you have a conceptual error.

Iframe apps are canvas apps, NOT Connect apps.

Canvas apps are applications that work inside the Facebook site, eg: from a tab from your profile. Canvas apps require you to configure a callback URL, which is the URL where your application resides. You shouldn't do steps 1-3 because Facebook will proxy the calls to your application so they can send your application session information about the user (through a POST or GET params).

Connect apps are external sites, like Digg, where you must do steps 1-3, but not step 4. Steps 1-3 are required to establish a communication channel with Facebook.

Please read http://wiki.developers.facebook.com/index.php/Connect/Setting_Up_Your_Site for a step by step guide for installing Connect in your site. After you are done with it, you can call FB.Connect.StreamPublish.
