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

Question

I am developing a simple java program to post automatically (articles) to my facebook fun page. I have created an app and have got an access_token using url : https://graph.facebook.com/oauth/access_token?grant_type=client_credentials&client_id=APP_ID&client_secret=CLIENR_SECRET. I use this java code to post to fun page wall :

String url = "https://graph.facebook.com/" + PAGE_ID + "/feed"
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("access_token", accessToken));
nvps.add(new BasicNameValuePair("message", item.getTitle()));
HttpClient client = new DefaultHttpClient(params);
HttpPost httpost = new HttpPost(url);
httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
HttpResponse response = client.execute(httpost);
HttpEntity entity = response.getEntity();

I got this error:

{
"error": {
      "message": "(#200) The user hasn't authorized the application to perform this action",
      "type": "OAuthException"
   }
}

How can I give my app authorization to post to my fun page ? thanks in advance

Wow, I see this same question asked at least once a day.

You will want to ask for manage_pages and publish_stream. Once the admin of the page authenticates, query me/accounts and grab the page's access token from that list. Using that page's access token, then you can post to me/feed.

Solution 2

simple, u just need to ask permissions..that's it..

String[] permissions = { "offline_access", "publish_stream", "user_photos", "publish_checkins","photo_upload" };
mFacebook.authorize(MainActivity.this, permissions,
            new LoginDialogListener());

I got a user access_token for page administrator using url : facebook.com/dialog/oauth/…, then the post goes to page wall. But still have problem : sent post is "as administrator" not "as page" so it doesn't appear on people who likes my fun page, it appears on "Everyone (Most Recent)"

I got access_token after admin authenticate application, but the message is posted as "admin" not "as page", this is important to show updates to people that likes my page. Thanks.

Hmmm, below you say just the opposite is what you're looking for "But still have problem : sent post is "as administrator" not "as page"" So which is it? Posting it as a page to the page, or as the admin to the page?

should use "page access token" as descr ibe in facebook doc page developers.facebook.com/docs/reference/api/page instead of user (admin) access token. Thanks Juicy Scripter

problem solved. I was able to post to page as page not as admin. I put an explaining note above. thx.

yes, this is what I described in my answer. How to post to the page as the page. :) This question is asked about once a day on average on SO. :O

It's worked in my case too but Where to place this code. And how to know that user already permitted this or not.

@KrishnakantDalal i did not get "where to place this code" . And Facebook UI will ask the permissions to the user when he first tries to login using Facebook. And it asks only once.

The key here is the "publish_stream" and "manage_pages" perms. With only "manage_pages" you'll get a bounce.
