Placing Forex Order

I am struggling to place buy/sell order through Python API for "USDINR SEP FUT". This is my first attempt to place a Forex order through API. I have placed multiple equity orders in last two months without any issues. Here is the script I am using. I am getting an exception of 'Unknown Trading Symbol'.

kite.place_order(tradingsymbol="USDINR SEP FUT", variety=kite.VARIETY_REGULAR, exchange=kite.EXCHANGE_NSE, transaction_type = kite.TRANSACTION_TYPE_SELL, quantity = 1, order_type=kite.ORDER_TYPE_MARKET, product=kite.PRODUCT_MIS)

Can someone help in what I am missing. Thanks in advance!
