Google Calender API

Google Calendar API

// Refresh Token: A long-lived token that is used to obtain a new access token without requiring user re-authentication.
// Access Token: A short-lived token (usually expires in 1 hour) that allows your application to access Google APIs on behalf of a user. It must be included in API requests as an Authorization header (e.g., Bearer <access_token>). Once expired, a new access token must be obtained using the refresh token.
