make an order kucoin API in python

Question

import requests, json, time


url = 'https://api.kucoin.com/api/v1/orders'

headers = {
    "KC-API-KEY": '',
    "KC-API-PASSPHRASE": '',
    "clientOid": "AAA",
    "side": "sell",
    "symbol": "BTC-USDT",
    "type": "market",
    "size": "0.001",
    
}
response = requests.post(url, headers=headers)
print(response.status_code)
print(response.json())

I am trying to place an order but it isn't working. Am I missing some parameters?

Error:

{'code': '400001', 'msg': 'Please check the header of your request for KC-API-KEY, KC-API-SIGN, KC-API-TIMESTAMP, KC-API-PASSPHRASE'}
