Auth.expireSession
From Facebook Developer Wiki
Contents |
Description
Invalidates the current session being used, regardless of whether it is temporary or infinite. After successfully calling this function, no further API calls requiring a session will succeed using this session. If the invalidation is successful, this will return true.
Parameters
| 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. | |
|---|---|---|---|---|
| session_key | string | The session key of the logged in user. The session key is automatically included by our PHP client. | ||
| 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. | ||
| optional | 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. |
