I use “wss://testnet.binancefuture.com/ws-fapi/v1”
def on_open(self,ws):
payload = {
“method”: “SUBSCRIBE”,
“params”: [“btcusdt@bookTicker”],
“id”: 3
}
ws.send(json.dumps(payload))
I got error in on_message(self,ws,message) as below
“{“id”:3,“status”:400,“error”:{“code”:-1000,“msg”:“Invalid ‘params’ in JSON request; expected an object.”}}”
