Cancel page tab notification

Does anyone know if deauthorize callback works for page tab apps? I installed this in the developer settings and it doesn't seem to work.

The page in question does not even touch. I have an input to see if the page failed, but nothing is displayed. Has anyone else got this job?

thanks

Access to the page? Check your log files to see if your callback has been hit.

The last time I checked our process, the signed_request value was not passed, instead the callback still got the value in $ _REQUEST ['fb_page_id']. You should also see the signature value, which you can use to validate the request using the pre signed_request methodology.
