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
}
