Kindly let us know if we could fetch option OI data for Nifty and Banknifty options. If yes please provide any documentation which is available

@smrtsaravanan it is working fine now. Ignore it.

I have made a couple of changes. 1st I have declared it like below

obj=SmartConnect(api_key=apikey)
totp = pyotp.TOTP(s='yourkey')
print("pyotp",totp.now())
attempts = 5
while attempts > 0:
attempts = attempts-1
data = obj.generateSession(username, pwd, totp.now())
print(data)
if data['status']:
break
tt.sleep(2)

and entered my new API key.

Hope it helps!

@admin Hi admin, when I try to validate totp i got below error.
refreshToken= data['data']['refreshToken']
TypeError: 'NoneType' object is not subscriptable
