How to place batch orders for futures

This url works fine to place batch order:

params = {
    "batchOrders": [
        {
            "symbol":"BTCUSDT",
            "side": "SELL",
            "type": "LIMIT",
            "quantity": "0.001",
            "timeInForce": "GTC",
            "reduceOnly": "false",
            "price": "9563.51"
        },
        {
            "symbol":"BTCUSDT",
            "side": "SELL",
            "type": "LIMIT",
            "quantity": "0.001",
            "timeInForce": "GTC",
            "reduceOnly": "false",
            "price": "9613.51"
        }
}

json encode the batch orders.

We have an example python script and work out of the box.
