How to check if I am fetching the right request token

Question

I am trying to create an auto login for zerodha. This is the code I am using but I keep getting error at this part

data = kite.generate_session(request_token, api_secret=key_secret[1])

The error is:

Traceback (most recent call last):

data = kite.generate_session(request_token, api_secret=key_secret[1])
