def __init__(self, *args, **kwargs):
        super(RetryAdapter, self).__init__(*args, **kwargs)
        self.max_retries = Retry(total=RETRY_COUNT,
                                 backoff_factor=BACKOFF_FACTOR)

        self.__key = key

        self._scheme = kwargs.get('scheme') or 'https'
        self._host = kwargs.get('host') or 'api.jwplatform.com'

        self._api_version = kwargs.get('version') or 'v1'
        self._agent = kwargs.get('agent')

        self._connection = requests.Session()

        self._connection.headers['User-Agent'] = 'python-jwplatform/{}{}'.format(
