Handling messages from Binance Websocket streams

User Data Stream

To subscribe I query listen key:

POST /api/v3/userDataStream

connect to websocket wss://stream.binance.com:9443/stream and send the listen key with the following message :

{
    "id": 1,
    "method": "SUBSCRIBE",
    "params": [
        "<my listen key>"
    ]
}

When Binance accepts the subscription it sends:

{
    "id": 1,
    "result": null
}

{
    "symbol": "KAVAUSDT",
    "orderId": 561657676,
    "orderListId": -1,
    "clientOrderId": "ce86e0a9-85a8-4d9b-99b1-b08e227e2464",
    "price": "4.80700000",
    "origQty": "10.00000000",
    "executedQty": "0.00000000",
    "cummulativeQuoteQty": "0.00000000",
    "status": "CANCELED",
    "timeInForce": "GTC",
    "type": "LIMIT",
    "side": "BUY",
    "stopPrice": "0.00000000",

    "updateTime": 1632184233620,
    "isWorking": true,
    "origQuoteOrderQty": "0.00000000"
}
