[edit] Parameters

Type	Name	Description
string	api_key	The application key associated with the calling application.
string	session_key	The session key of the logged in user.
float	call_id	The request's sequence number. Each successive call for any session must use a sequence number greater than the last. We suggest using the current time in milliseconds, such as PHP's microtime(true) function.
string	sig	An MD5 hash of the current request and your secret key, as described in the authentication guide.
string	v	This must be set to 1.0 to use this version of the API.
string	format	Optional - desired response format. Either "XML" (default) or "JSON".
string	callback	Optional - wrap the response inside a function call. This is primarily to enable cross-domain javascript requests using the <script> tag, sometimes known as "JSONP". This works with both XML and JSON.

[edit] Return Value

map: id-value pairs of preferences. For preferences that are set to 0 or empty strings, they will NOT show up in the returned map.

-This is a problem if you identify the preferences by numbers on your machine. If a user fills out preference 0, 1, 2, and 4, but neglects to fill out preference 3 (because it may be optional) --> The array returned by this function will map preference 4 to 3. This preference will still be identified by 4 because each initial key in the returned array stores another array that would map 4 to the user preference, but you may have to iterate through each array until you find this missing preference depending on how many preferences you have and how many are missing. --Arcfoundation 03:39, 29 June 2008 (PDT)
