Subscribe Assets

API Description

This Websocket provides real-time updates on asset balances when trading activity occurs on the user's spot account after the connection is established.

Note: Asset data is accessible via both RESTful and Websocket APIs. This page describes the Websocket API. For information on the RESTful API, please click here

Precautions

1. The Websocket connection only returns real-time updates for assets affected by orders that enter trading after the connection is established. Updates for pre-existing orders or already executed trades prior to connection will not be pushed. Users should ensure that they have active trading activity to receive real-time updates.

Authentication

This is a private interface and requires authentication. For details on using the RESTful API, please refer to Introduction > Authentication & Code Snippet > Spot > Websocket Private Interface.
