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
| 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. | |
|---|---|---|---|---|
| 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. If you specify the call ID 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. | ||
| 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. |
