The headers are set incorrectly wrong

[SimplicityGuy]

The correct headers to pass to an API call are:

    headers = {
            'Accept': 'application/json',
            'Authorization': 'Bearer {0}'.format(access_token)
        }

You mean:

        headers = {
            'Content-Type': 'application/x-www-form-urlencoded',
            'Accept': 'application/json',
            'Host'  : 'https://jawbone.com',
            'Authorization': 'Bearer {0}'.format(access_token)
        }

should be converted to

   headers = {
            'Accept': 'application/json',
            'Authorization': 'Bearer {0}'.format(access_token)
        }
