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

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

Coverage Summary

Kraken SDK support for spot, futures, and WebSocket connectivity.

Who This SDK Is For

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

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

Kraken REST API Scope

Use the Kraken SDK for spot, futures, account, order, balance, and market data workflows that need typed REST methods and signed private requests.

Kraken WebSocket Scope

Use WebSocket clients for Kraken public market streams, private account/order events, and Spot WebSocket API request/response trading flows in the product areas supported by the SDK.

Authentication, Rate Limits & Reliability

Keep API key permissions, nonce/timestamp handling, and futures-vs-spot client boundaries explicit; monitor reconnect and resubscribe behavior in long-running services.

Supported Feature Areas

  • Spot
  • Futures
  • WebSockets
  • WebSocket API

Common Integration Workflows

  • Build authenticated Kraken REST API workflows for account state, balances, and order execution.
  • Stream Kraken 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 Kraken 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 Kraken derivatives workflows.
