APIs, Automation, Algos & Code

I am placing a sl order with these parameters

        res = api.place_order(security_id="59004", exchange_segment="NSE_FNO", transaction_type="SELL",
                    quantity=150, order_type="STOP_LOSS", product_type="INTRADAY", price=97.5, trigger_price=98 )

but keep getting error
{‘error_code’: ‘DH-906’, ‘error_type’: ‘Order_Error’, ‘error_message’: ‘Invalid Token’}

why is this happening, same code used to work before

Hey @Kush ,

We want to inform you that as per the Dhan library, to place an SL order, you need to follow the payload format below:

dhan.place_order(
    security_id='XXXXX',
    exchange_segment=dhan.NSE_FNO,
    transaction_type=dhan.SELL,
    quantity=150,
    order_type=dhan.SL,
    product_type=dhan.INTRA,
    trigger_price=10,
    price=9.50
)

For the complete request structures, please refer to:

We request you to also regenerate your access token before placing your orders.

We request you to also regenerate your access token before placing your orders.

code is placing sl orders automatically when a buy order is executed, and algo gets that info via order websocket, so that means my access token is correct.
I also verify my access token on startup before starting algo.

if you see the constants values in dhan python library, they are the same

class dhanhq(Order, ForeverOrder, Portfolio, Funds, Statement, TraderControl, Security,
             MarketFeed, HistoricalData, OptionChain):
    """DhanHQ Class having Core APIs"""

    """Constants for Exchange Segment"""
    NSE = 'NSE_EQ'
    BSE = 'BSE_EQ'
    CUR = 'NSE_CURRENCY'
    MCX = 'MCX_COMM'
    FNO = 'NSE_FNO'
    NSE_FNO = 'NSE_FNO'
    INTRA = "INTRADAY"
    SL = "STOP_LOSS"
    SELL = 'SELL'

and like i mentioned, code used to work earlier
