What this example covers

  • Gate WebSocket API request/response JavaScript example.
  • Uses the Siebly Gate SDK package gateio-api instead of hand-written WebSocket plumbing.
  • Source path: Gate/Websocket/WS-API/ws-private-perp-futures-wsapi.ts.
  • Example category: WebSocket API.
  • Imports SDK symbols including WebsocketClient.
  • Calls SDK methods such as on(), sendWSAPIRequest().

How to use this example

  • Start here for the specific request or stream pattern, then check the matching SDK guide for install, credentials, and operational notes.
  • For WebSocket examples, keep reconnect, resubscribe, heartbeat, and event-handler behavior explicit in your service.
  • Open the repository source when you need the latest committed version: GitHub source file.
