OAuth2 Only Authentication

One of the options to authenticate with is using 'OAuth2' alone method. This page goes over the OAuth2 Authentication:

Example

 // Sets the OAuth2 only Authentication
 $api = new SparkAPI_OAuth($client_id, $client_secret, $application_uri);
 
 // This is similar to our OpenId and OAuth2 Hybrid authentication call.  The interface for each client is identical.
 // To build the URI to redirect the end user to, invoke the "authentication_endpoint_uri" method, e.g.:
 header("Location: " . $api->authentication_endpoint_uri());
 
 // After this "code" is retrieved and you are redirected back, you will need to issue a Grant request with the "code" value brought back.  Once the Grant is returned, you'll want to test that it was successful and set your Access Token and Refresh Token
 $grant = $api->Grant($result, "authorization_code");

 if ($grant == true) {
    // These values can be saved and reused in future request then.
    $accesst = $api->SetAccessToken($api->oauth_access_token);
    $refresht = $api->SetRefreshToken($api->oauth_refresh_token); 
 } else {
      print_r("Something went wrong.");
      echo "API Error Code: {$api->last_error_code}<br>\n";
      echo "API Error Message: {$api->last_error_mess}<br>\n";
 };

 // After this is settled, you should be able to make pulls from the system, for example:

 $resultGetListings = $api->GetListings();
 if ($resultGetListings === false) {
      echo "API Error Code: {$api->last_error_code}<br>\n";
      echo "API Error Message: {$api->last_error_mess}<br>\n";
      exit;
 } else {
      print_r($resultGetListings);
 }
