According to the announcement from Binance, significant updates are scheduled for Binance Margin's user data streams on November 10, 2025. The current method of receiving user data streams using a listenKey at wss://stream.binance.com:9443 will be deprecated. This change will affect several requests, including POST, PUT, and DELETE operations related to user data streams and isolated user data streams. Users are advised to transition to a new subscription method utilizing a listenToken.
The new user data stream subscription with the WebSocket API will involve creating a new user data stream and returning a listenToken through the POST /sapi/v1/userListenToken request. Users can then subscribe to the user data stream using the listenToken method, which is expected to offer improved performance with lower latency. The existing User Data Stream documentation will continue to serve as a reference for the payloads users can receive, including account updates, balance updates, and order updates. Account updates will be triggered by outboundAccountPosition events whenever an account balance changes, detailing the assets affected by the balance change. Balance updates will occur when funds are transferred between accounts, while order updates will be communicated through executionReport events.
Binance assures users that trading activities will not be impacted by these updates. The announcement emphasizes the importance of transitioning to the new listenToken method to ensure continued access to user data streams. Users are encouraged to review the updated documentation for detailed information on the changes and how to implement them effectively.
