from SmartApi import SmartConnect

smartapi = SmartConnect(api_key)

login-url = smartapi.login_url()

# user is logged in using login url here and required tokens are collected using redirect url

#session = smartapi.generate_session(clientid,pwd,totp) <-- cannot be used!
profile = smartapi.get_profile() <-- Throws error: AG8001
