Need help in Twitter api (Abraham's TwitterOAuth: Could Not Authenticate You Problem)

Well,

I am using Abraham's TwitterOauth library to build an application that will collect oauth token and oauth token secret for each user and save it to database. So that later I can tweet on behalf of them.

I am doing it correctly. When user clicks on Allow this Application my app is getting authorized and user is redirected to the callback. I am also getting the Oauth token and Oauth token secret. But it's not working when it comes to update status or read timeline or do anything else with user's account.

I have read and write access in settings. My consumer keys and secret are correct.

It says Could Not Authenticate You.. What might be the problem? Please see my code below-

Here is the code for index.php (URL for the application):

<?php
session_start();
require_once 'twitteroauth.php';
require_once 'OAuth.php';
define("CONSUMER_KEY", "My key here");
define("CONSUMER_SECRET", "my secret here");
$to = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET);
$tok = $to->getRequestToken($_REQUEST['oauth_verifier']);
$request_link = $to->getAuthorizeURL($tok);
$_SESSION['oauth_access_token']= $tok['oauth_token'];
$_SESSION['oauth_access_token_secret'] = $tok['oauth_token_secret'];
header("Location: $request_link");
exit;
?>

PHP:

Code For callback.php:

<?php
session_start();
require_once 'twitteroauth.php';
require_once 'OAuth.php';
define("CONSUMER_KEY", "My Key");
define("CONSUMER_SECRET", "My Secret");
if ((!isset($_SESSION['oauth_access_token'])) || ($_SESSION['oauth_access_token'])=='') 
{
$to = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $_SESSION['oauth_request_token'], $_SESSION['oauth_request_token_secret']);
$token_credentials = $to->getAccessToken($_REQUEST['oauth_verifier']);
$_SESSION['oauth_access_token'] =$token_credentials['oauth_token'];
$_SESSION['oauth_access_token_secret'] = $token_credentials['oauth_token_secret'];
}
$to=new TwitterOAuth(CONSUMER_KEY,CONSUMER_SECRET,$_SESSION['oauth_access_token'],$_SESSION['oauth_access_token_secret']);
$content = $to->post('statuses/update', array('status' => 'Hello Twitter')); 
var_dump($content);
?>

PHP:

It gives the following Output:

object(stdClass)#5 (2) { ["error"]=> string(27) "Could not authenticate you." ["request"]=> string(23) "/1/statuses/update.json" }

It says "Could Not Authenticate You"...

Any help will be highly appreciated..

Thanks A Lot!

 

"Could Not Authenticate You" means the access_token being used is invalid. You are likely overwriting it at some point with a new request_token.

 

Hello Abraham

It is very nice to talk to you. But I am using the above two files only. Could you please look into the code and point out where I am doing wrong? I am unable to find where the access token is getting overwritten.

 

In the first file you are saving the request_token in the session as oauth_access_token but in the second file you are trying to use the request_token from oauth_request_token.

 

Thanks a lot Abraham.. I figured it out. It is working now!
