Fbml.refreshRefUrl
From Facebook Developer Wiki
Contents |
Description
Fetches and re-caches the content stored at the given URL, for use in a fb:ref FBML tag. See the FBML documentation for a description of the markup and its role in various contexts.
There is a timeout on the callback so make sure your refURL response time is fast enough.
Parameters
| Required | Name | Type | Description | |
| 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. | ||
| url | string | The absolute URL from which to fetch content. This URL should be used in a fb:ref FBML tag. | ||
| 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. |
