Description

As we announced on the Platform Status Feed, all Marketplace APIs are deprecated as of March 3, 2009.


Returns the Marketplace subcategories for a particular category.

Parameters

RequiredNameTypeDescription
required api_key string The application key associated with the calling application.
call_id float 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.
sig string An MD5 hash of the current request and your secret key, as described in the How Facebook Authenticates Your Application.
v string This must be set to 1.0 to use this version of the API.
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.
category string Filter by category. If this is not a valid category, no subcategories get returned.
