If I create an application on Facebook that populates the canvas / iframe on Facebook, do I have to have anything on the home domain that also works? For example, if I have myapp.com do I need an interface on that page that operates independent of facebook for any reason or can I just use my home domain to serve the php files for the iframe in facebook? Also, is there any reason I can’t have a separate set of webpages not in facebook that introduce the app, about, contact us, etc.?
Thanks.
Your app will run from your webserver but doesn’t have any requirements for showing anything directly from your website. In other words you could create a directory on your webserver and isolate your app.
I’m not aware of any limitations discussing your app in your website but a quick glance over the FB terms of service might highlight anything specific you’re trying to do.
