Invalid 'api_key' or 'access_token'

shashankm8

Hi,

i have written a python client which gets historical data from zerodha, and checks for sma crossover. If the buy condition is satisfied an order needs to be placed.

from kiteconnect import KiteTicker,KiteConnect
import pandas as pd
from datetime import datetime, timedelta
import talib

if __name__ == '__main__':
    api_key=open('api_key.txt','r').read()
    api_secret = open('api_secret.txt','r').read()

    kite = KiteConnect(api_key=api_key)

    access_token = open('access_token.txt', 'r').read()

    kite.set_access_token(access_token)

    # print(kite.login_url())
    # data = kite.generate_session("p0g6JdwUlrEqBAyruSTBfynE512nJULK", api_secret=api_secret)
    # print(data['access_token'])
    # kite.set_access_token(data['access_token'])
    # with open('access_token.txt', 'w') as ak:
    #     ak.write(data['access_token'])
    #
    #

    # # Dates between which we need historical data
    from_date = datetime.strftime(datetime.now() - timedelta(100), '%Y-%m-%d')
    to_date = datetime.today().strftime('%Y-%m-%d')

    # Interval(minute, day, 3 minute, 5 minute...)
    interval = "5minute"
    current_signal = ''
    tokens = {738561: 'RELIANCE', 341249: 'HDFCBANK'}

#following line  is just to check if kite,place_order is working or not

                kite.place_order(tradingsymbol=tokens[token], variety="REGULAR",exchange="NSE", quantity=1, transaction_type="BUY",order_type="MARKET", product="CNC")

    while True:
        # if (datetime.now().second == 0) and ((datetime.now().minute) % 5 == 0):
            for token in tokens:
                records = kite.historical_data(token,from_date=from_date,to_date=to_date,interval=interval)
                df = pd.DataFrame(records)
                df.drop(df.tail(1).index, inplace=True)
                # print(df)
                open = df['open'].values
                high = df['high'].values
                low = df['low'].values
                close = df['close'].values
                volume = df['volume'].values

                sma5 = talib.SMA(close,5)
                sma20 = talib.SMA(close,20)
                print(sma5[-1])
                print(sma20[-1])

#following line  is just to check if kite,place_order is working or not

                kite.place_order(tradingsymbol=tokens[token], variety="REGULAR",exchange="NSE", quantity=1, transaction_type="BUY",order_type="MARKET", product="CNC")

#actual buy and sell logic
                if (sma5[-2] < sma20[-2]) and (sma5[-1] > sma20[-1]):
                    buy_order_id = kite.place_order(tradingsymbol=tokens[token], exchange="NSE", quantity=1,transaction_type="BUY", order_type="MARKET", product="CNC")
                    # current_signal = 'buy'

                if (sma5[-2] > sma20[-2]) and (sma5[-1] < sma20[-1]):
                    sell_order_id = kite.place_order(tradingsymbol=tokens[token], exchange="NSE", quantity=1,transaction_type="SELL", order_type="MARKET", product="CNC")
                    # current_signal = 'sell'

If the kite.place_order is placed ooutside the while loop i.e before calling historical data api, it is working fine otherwise invalid access_token error us thrown

Following is the output

1759.3900000000133
1750.2950000000012

kiteconnect.exceptions.InputException: Invalid `api_key` or `access_token`.

As seen above, SMA values are being printed that means i'm successfully getting historical data. But not able to place order

It seems like you are not sending proper auth header. I would suggest running pykiteconnect with debug logs on and check if you are sending proper auth headers.

In that case, it shouldn't work outside the while loop as well right? only when i combine historical data and placing order it's not working

replaced the kite.place_order(tradingsymbol=tokens[token], variety="REGULAR",exchange="NSE", quantity=1, transaction_type="BUY",order_type="MARKET", product="CNC") with

order_id = kite.place_order(tradingsymbol=tokens[token],
exchange=kite.EXCHANGE_NSE,
transaction_type=kite.TRANSACTION_TYPE_BUY,
quantity=1,
order_type=kite.ORDER_TYPE_MARKET,
product=kite.PRODUCT_MIS)

and it worked..
