This call will redirect the user to the Ellipsis Drive authorization page for the authorization of the requested scope. If the authorization is completed successfully the user is redirected to the redirect URI with query parameters code, containing an authorization code that is valid for 1 minute, and state (if supplied in the request) that should be checked to avoid CSRF attacks. Alternatively, if an error occurs during the authorization the user is redirected to the given redirect URI if possible, with query parameters error, error_description and state describing why the process failed (e.g. error='access_denied', error_description='The user has refused access.').
