How to post on the wall using stream_publish

Question

I got the following exception when i try to post a message on a friends wall using the REST API

The user hasn't authorized the application to perform this action

here is my code.

$status=$facebook->api_client->stream_publish($message,null,null,$id,$user);

How to get authorization from a user to post a message on his wall? Or any work around to do this ?

Answer 1

During the authentication process, you need to request the publish_stream extended permission from the user before your application is allowed to post on behalf of that user.

Assuming this is a canvas application, this page will probably help you along.
