General WSS information

Base Address​

wss://fstream.xt.com/ws/user

Request Headers​

The request header of the compression extension protocol must be added:

Sec-Websocket-Extensions: permessage-deflate

Subscription Steps​

Step 1: Call the interface /v1/user/listen-key to obtain the listenKey.

Step 2: When subscribing to user-related WebSocket events, send:

{
  "method": "SUBSCRIBE",
  "params": ["order@{listenKey obtained in the previous step}"],
  "id": "test1"
}

Notes​

  • If you receive invalid_listen_key, it means the listenKey is expired or invalid. 👉 Re-request a new listenKey through the interface.
  • User-related data will be pushed after subscription is successful.
