Friends.get
From Facebook Developer Wiki
Contents |
Description
Returns the Facebook user IDs of the current user's Facebook friends. The current user is determined from the session_key parameter. The values returned from this call are not storable.
You can call this method without a session key to return a list of friends of a user on your application's canvas page. The user must have authorized your application in order to make this call without a session key. This is similar to how Facebook passes the UIDs of friends of a user on your application's canvas page.
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. | ||
| optional | session_key | string | The session key of the logged in user. | |
| 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. | ||
| flid | int | Returns the friends in a friend list. | ||
| uid | int | The user ID for the user whose friends you want to return. Specify the uid when calling this method without a session key. |
Response
Privacy Note: The friend IDs returned are the friends that are visible to the Facebook Platform. If no friends are found, the method returns an empty friends_get_response element.
