Twitter OAuth Could not authenticate you when using screen_name

Question

I have an application which needs to get a feed of favourites from a user. If I set it up using oauthdamnit it seems to work fine:

This

$api = new OAuthDamnit(TWITTER_CONSUMER_KEY, TWITTER_CONSUMER_SECRET, TWITTER_ACCESS_TOKEN, TWITTER_ACCESS_TOKEN_SECRET);

$raw = $api->get('https://api.twitter.com/1.1/favorites/list.json');
$response = json_decode($raw, true);
print_a ($response);

Returns this:

 Array
(
    [0] => Array
        (
            [created_at] => Mon Apr 14 19:32:26 +0000 2014
            [id] => 455790703126532096
            [id_str] => 455790703126532096
            [text] => Gmail put an update about Google+ straight ... etc

But I need to get them from another user – when I add ?screen_name=YSL for example:

This:

$api = new OAuthDamnit(TWITTER_CONSUMER_KEY, TWITTER_CONSUMER_SECRET, TWITTER_ACCESS_TOKEN, TWITTER_ACCESS_TOKEN_SECRET);

$raw = $api->get('https://api.twitter.com/1.1/favorites/list.json?screen_name=YSL');
$response = json_decode($raw, true);
print_a ($response);

Returns this:

Array
(
    [errors] => Array
        (
            [0] => Array
                (
                    [message] => Could not authenticate you
                    [code] => 32
                )

        )

)

What am I doing wrong? https://dev.twitter.com/docs/api/1.1/get/favorites/list

Answer 1

You are doing it wrong in $api->get.

If you want to pass parameter to url with GET request then pass it in function get as a SECOND parameter as array

$raw = $api->get('https://api.twitter.com/1.1/favorites/list.json',array('screen_name'=>'YSL'));

Here is the source code which says it self to pass $params in second parameter as an Array :

function get($url, $params = array()) {
     return $this->request('GET', $url, $params);
}

You can find it in oauthdamnit.php line no 39

Answer 2

The API call only returns the favorites for the authenticated user and can't return data of arbitrary users, see the twitter API docs:

Returns the 20 most recent Tweets favorited by the authenticating or specified user.

Source: https://dev.twitter.com/docs/api/1.1/get/favorites/list

You have to obtain the correct username and password in order to make this API call work.
