InputException: invalid token error when fetching historical data

algoumesh

first I generated session token by using login and then generated access token using:
data = kite.generate_session("xttyxxxxxxxxxxxxxxxxxx", api_secret=key_secret[1])
kite.set_access_token(data["access_token"])

I am able to fetch many details, like kite.instruments("NSE") etc. but API is failing with error "InputException: invalid token" when I try to get historical data using
kite.historical_data("TCS",from_date,dt.date.today(),"5minute")

same code was working fine, issue occurring since last night.

Could you log in to your developer account and confirm whether the Historical API is active.

kite.historical_data("TCS",from_date,dt.date.today(),"5minute")

You are assigning wrong token, instead of "TCS"(trading symbol) it should be instrument token. Go through the documentation here.

algoumesh

tried other symbols also,
like

new_data = kite.historical_data("SBIN",from_date,dt.date.today(),"15minute")

still same issue.

You can read the documentation as mentioned above by @rakeshr

I was running in loop, so could not find it early. issue was only with TATAMTRDVR stocks. removed it from loop and working fine.
