I am not getting any success on the automatic generation of the access token. I am getting an error of list index out of range in function kite_post_two_fa because of the value of response.headers['Location'] is https://kite.zerodha.com/connect/finish?api_key=0xxxxxxxxxrxxxxx&sess_id=mVW5XlgjxH5qIP6jRSU0Dmi9xqrZLl9g (i.e. the URL does not contain the key work request_token=)

Althouhg I am getting output of {'status': 'success', 'data': {'profile': {}}} on 'kite_twofa function that means till TWOFA , the script is working fine but when I add &skip_session=true to ref_url, kite terminate the session. Any idea how to solve this issue? Thanks.

This modification worked for me.

I just now created a simple version that works with external 2FA TOTP: https://github.com/rajivgpta/kite-api-autologin . Working as of 23 feb 2023.

Hi, is this still working for you?
I am receiving below error while using it.

request_token = parse_qs(urlparse(response).query)['request_token'][0]
KeyError: 'request_token' 

I noticed my url is as below, not sure why request_token is not part of it.
'https://kite.zerodha.com/connect/login?sess_id=*******&api_key=*****7&skip_session=true'
