[edit] Description

Publishes a Mini-Feed story to the user corresponding to the session_key parameter, and publishes News Feed stories to the friends of that user who have added the application.

[edit] Parameters

Required	Name	Type	Description
required	api_key	string	The application key associated with the calling application.
	session_key	string	The session key of the logged in user.
	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 authentication guide.
	v	string	This must be set to 1.0 to use this version of the API.
	title	markup	The markup displayed in the feed story's title section.
optional	format	string	Desired response format. Either XML (default) or JSON.
	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.
	body	markup	The markup displayed in the feed story's body section.
	image_1	string	The URL of an image to be displayed in the News Feed story.
	image_1_link	string	The URL destination after a click on the image referenced by image_1.

[edit] Example Return XML

<?xml version="1.0" encoding="UTF-8"?> <feed_publishActionOfUser_response xmlns="http://api.facebook.com/1.0/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://api.facebook.com/1.0/ http://api.facebook.com/1.0/facebook.xsd"> 1 </feed_publishActionOfUser_response>

[edit] Response

The function returns 1 on success, 0 on permissions error, or an error response.

[edit] Notes

Publishing to Feeds requires you to understand the rules of their operation.

• The title is required, and is limited to 60 displayed characters (excluding tags).
  • One <a> tag is allowed.
  • One fb:userlink tag is allowed, and the uid parameter must be populated with the user ID on whose behalf the action is being published. If there is no such fb:userlink tag found, then one is automatically prepended to the title.
  • The fb:name tag is allowed, and there may be multiple instances of this tag.
  • No other tags are allowed.
• The body is optional, is limited to 200 display characters (excluding tags), and can include the tags fb:userlink, fb:name, <a>, <b>, and <i>.
• Up to 4 images can be displayed, which will be shrunk to fit within 75x75, cached, and formatted by Facebook. Images can either be a URL, or a Facebook PID. (RobRoy: PID doesn't work for me, anyone else verify?) If it is a URL, you must own the image and grant Facebook the permission to cache it. Each image must have a link associated with it, which must start with http://
• Applications are limited to calling this function 10 times for each user in a rolling 48-hour window.
• The story may or may not show up in the user's friends' News Feeds, depending on the number and quality of competing stories.
• The word "message" is disallowed in a feed story. Attempting to publish a story with the word "message" will result in an error being returned.
• Developer Note: Since this method affects all Facebook friends of the developer, testing this method does abide by the limited-calling rule (unlike feed.publishStoryToUser).
