Step 5: Refresh the Tokens

To refresh the access token and, consequently, the refresh token, make the following request using the most recent refresh token:

The request must follow this format (line breaks added for clarity):

https://app.beamlabs.io/oauth/v2/endpoints/token/?
    client_id=<CLIENT_ID>&
    client_secret=<CLIENT_SECRET>&
    grant_type= authorization_code&
    refresh_token=<REFRESH_TOKEN>&
    grant_type=refresh_token

where <REFRESH_TOKEN> is a valid refresh token received from Step 3.
