I'm wondering if Twitter has an API endpoint that exchanges an expired access token with an active one. The way that I have the login flow working right now goes something like this.
// Request a token and redirect to the authorization page
$token = $this->twitter->getRequestToken();
// Set the session data
$this->session->set_userdata('oauth_token', $token['oauth_token']);
$this->session->set_userdata('oauth_token_secret', $token['oauth_token_secret']);
// Redirect the user to the authorization page
header('Location: https://api.twitter.com/oauth/authorize?oauth_token='.$token['oauth_token']);
The page that the user is redirected to will prompt the user to authorize my app each and every time they want a valid access token. Upon accepting the authorization, the user will be redirected to the callback URL. At my callback URL, the following happens
// Get the parameters from the URL
$token = $this->input->get('oauth_token');
$verifier = $this->input->get('oauth_verifier');
$oauthToken = $this->session->oauth_token;
$oauthSecret = $this->session->oauth_token_secret;
// Get the access token
$access = $this->twitter->getAccessToken($verifier, $oauthToken, $oauthSecret);
Does such a way exist for an access token to be generated without having to authorize my app each and every time?
