OKX API Node.js, JavaScript & TypeScript SDK by Siebly

OKX integration resources, package links, and quick start guides.

Coverage Summary

OKX SDK support for spot, futures, options, grid workflows, and live market streaming.

Who This SDK Is For

The OKX Node.js, JavaScript & TypeScript SDKs are built for teams & individual software developers that need reliable Spot, Futures, Options, Grid, WebSockets, WebSocket API integrations in production systems.

Each language-specific guide below shows how to use the same OKX SDK package in that environment, with runnable examples linked for scenario-specific workflows.

OKX REST API Scope

Use the OKX SDK for spot, futures, options, account, trade, and market data workflows where instrument identifiers and product type fields drive routing.

OKX WebSocket Scope

Use WebSocket clients for public and private streams across supported OKX instrument families, including market data and account event flows.

Authentication, Rate Limits & Reliability

Normalize instrument IDs, product-family fields, timestamp handling, and signing inputs before building shared services; monitor connection state and resubscribe after reconnects.

Supported Feature Areas

  • Spot
  • Futures
  • Options
  • Grid
  • WebSockets
  • WebSocket API

Common Integration Workflows

  • Build authenticated OKX REST API workflows for account state, balances, and order execution.
  • Stream OKX market and account events over WebSocket with reconnect-aware handling.
  • Deploy typed Node.js services with explicit request/response models and predictable error handling.
  • Use OKX WebSocket API endpoints for low-latency request/response interactions where supported.

Implementation Guidance

  • Never store API keys in source files. Follow best practices for protecting API keys and secrets, as you would a password.
  • Start in testnet or low-risk modes before routing automation to production account credentials.
  • To consume WebSocket events, use the exported WebsocketClient from each SDK. Be sure to use the event handlers (message or update, depending on SDK) to handle incoming events after subscribing.
  • For REST API calls, use the provided REST client classes and methods to ensure proper signing, authentication, and error handling. These classes are exported by every SDK and provide fully typed functions wrapped around individual API endpoints. Refer to the quick start guides for code snippets and patterns.
  • Track package updates and changelog entries through the release feed before upgrading live systems.
  • Validate leverage, margin, and liquidation-sensitive request paths carefully for OKX derivatives workflows.
  • Model contract metadata and expiry handling explicitly when integrating OKX options endpoints.
