I think there is an issue in line number 62
AttributeError: 'KiteConnect' object has no attribute 'request_access_token'
data = kite.request_access_token(request_token, secret=kite_api_secret)

Access token can be set/get using below code:

 data = kite.generate_session(request_token, api_secret=kite_api_secret)
 kite.set_access_token(data["access_token"])
 access_token =data["access_token "]

Check updated version for Kite 3 here - https://github.com/zerodhatech/pykiteconnect/blob/master/examples/flask_app.py

I didn't understand how you generated request token automatically. Can you please help with that?

request_token = request.args.get("request_token")

How this line works?
