new order api: invalid request

API Spot/Margin API
1

Hi, i have a problem when i call the “order” endpoint.
My request is:
https://api.binance.com/api/v3/order?symbol=BTCEUR&side=BUY&type=LIMIT&timeInForce=GTC&quantity=0.01&price=9850&recvWindow=30000&timestamp=1597066653266&signature=27D1882AF…

The server response with an error:
Remote server error: 400 not valid request;

Why?
i try with postman and i get this error:

{

"code": -1101,

"msg": "Too many parameters; expected '6' and received '9'."

}

2

My key and signature is valid because with other endpoint works properly
