staying authenticated on multiple extensions in python to avoid rate limits

To read all users' call data on a single API call, you can login (authenticate) your app with a super admin user (e.g. the default 101 extension), then read the call log at the account level (see the reference)

Now, if you need to login every time you call an API, you can implement the authentication this way:

from ringcentral import SDK
import json
from os import path

rcsdk = SDK( RINGCENTRAL_CLIENTID, RINGCENTRAL_CLIENTSECRET, RINGCENTRAL_SERVER)
platform = rcsdk.platform()

def login():
    res = platform.login(RINGCENTRAL_USERNAME, RINGCENTRAL_EXTENSION, RINGCENTRAL_PASSWORD)
    file = open("access-tokens.json",'w')
    file.write(res.text())
    file.close()
    read_calllog()

def read_calllog():
    platform = rcsdk.platform()
    file = open("access-tokens.json",'r')
    tokens = file.read()
    platform.auth().set_data(json.loads(tokens))
    if platform.logged_in() == False:
        print ("token expired. Relogin")
        login()
    else:
        params = {
            'dateFrom': "2019-01-01T00:00:00.000Z",
            'type': ['Voice'],
            'direction': ['Outbound']
        }
        resp = platform.get('/restapi/v1.0/account/~/call-log', params)
        for record in resp.json().records:
            print "Call type: " + record.type

if path.exists("access-tokens.json"):
    print("has token")
    read_calllog()
else:
    print ("must login")
    login()
