Determining if facebook app has been bookmarked from Facebook REST API

I am running a Facebook app as an iframe and have to find out if it was already bookmarked. I know it's trivial to find out if the user of your facebook app has already installed it, but how can I tell if they've already bookmarked it?

To be clear, I am not referring to the browser bookmark, I am talking about the Facebook bookmark bar.

Thanks.

I don't think this is possible. The rationale I saw for it on the forums is to prevent apps from rewarding users who pledged the app or malicious users who didn't.

The closest you can get to your app's settings is in the Developer app, and there is an option in Canvas -> Bookmark URL where you can specify the entry point of your app when the user clicks on a bookmark. The default URL matches the Canvas URL if it is empty.



In theory, you could add a parameter or change the location of the bookmark URL to identify the user who clicked the bookmark. Obviously this is not ideal as you cannot tell when the user is deleting a bookmark and the user can still log into the application without clicking on the bookmark.
