Description

Revokes the specified extended permission for the selected user. If no user is specified, then the user of the current session is used.

Required	Name	Type	Description
required	api_key	`string`	The application key associated with the calling application. If you specify the API key in your client, you don't need to pass it with every call.
	sig	`string`	An MD5 hash of the current request and your secret key, as described in the How Facebook Authenticates Your Application. Facebook computes the signature for you automatically.
	v	`string`	This must be set to `1.0` to use this version of the API. If you specify the version in your client, you don't need to pass it with every call.
	perm	`string`	The extended permission to revoke.
optional	uid	`int`	The user ID of the user whose extended permission you want to revoke. If you don't specify this parameter, then you must have a valid session for the current user, and that session's user will have the specified permission revoked.
	format	`string`	The desired response format, which can be either `XML` or `JSON`. (Default value is XML.)
	callback	`string`	Name of a function to call. This is primarily to enable cross-domain JavaScript requests using the <script> tag, also known as JSONP, and works with both the XML and JSON formats. The function will be called with the response passed as the parameter.
