The Access token expires in 2 hours by default. Once your access token has expired, you can use this API to issue a new Access token using your refresh token. The refresh token must be the same that you received in the Get Access token API.
This will generate a new set of Access token and Refresh token for you. Save them securely in your application against the user.
