Facebook deauthorize my app

Question

Can I use Facebook PHP SDK to deauthorize my app for a particular user, basically I like to have a toggle so the user can link or unlink their facebook account to my site, I

Answer 1

Not using the currently supported Graph API: as currently setup there is no interface in the Graph API (or even the legacy APIs) to deauthorize an application. The user has to explicitly choose to do it themselves through the Facebook settings pages.

However...

The legacy REST api has http://developers.facebook.com/docs/reference/rest/auth.revokeAuthorization/, which SOUNDS like it does what you want.

Let me know if that works for you: I'm curious.
