Refreshing a Token - oliverschloebe/oauth2-rbtv GitHub Wiki

Once your application is authorized, you can refresh an expired token using a refresh token rather than going through the entire process of obtaining a brand new token. To do so, simply reuse this refresh token from your data store to request a refresh.

$rbtvProvider = new \OliverSchloebe\OAuth2\Client\Provider\Rbtv([
	'clientId'	=> 'yourId',          // The client ID of your RBTV app
	'clientSecret'	=> 'yourSecret',      // The client password of your RBTV app
	'redirectUri'	=> 'yourRedirectUri'  // The return URL you specified for your app on RBTV
]);

$existingAccessToken = getAccessTokenFromYourDataStore();

if ($existingAccessToken->hasExpired()) {
	$newAccessToken = $rbtvProvider->getAccessToken('refresh_token', [
		'refresh_token' => $existingAccessToken->getRefreshToken()
	]);

	// Purge old access token and store new access token to your data store.
}
