KuCoin JavaScript SDK example: authorizationHeader.ts
KuCoin authorization header JavaScript example for the Siebly KuCoin SDK, covering exchange REST API and WebSocket integration, setup, and production SDK docs.
We use environment variables in our examples for API keys. It is your responsibility to manage and secure your keys appropriately.
examples/Kucoin/Auth/authorizationHeader.ts
What this example covers
- KuCoin authentication and request-signing JavaScript example.
- Uses the Siebly KuCoin SDK package
kucoin-apiinstead of hand-written signing code. - Source path:
Kucoin/Auth/authorizationHeader.ts. - Imports SDK symbols including
SpotClient. - Calls SDK methods such as
getBalances(),setAccessToken().
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 private or order-management examples, keep credentials in environment variables or a secret manager. Use read-only keys where possible, and check the execution mode reference before any exchange write path can run.
- Open the repository source when you need the latest committed version: GitHub source file.
import { SpotClient } from 'kucoin-api'; async function start() { /** * All REST clients support passing the access token. If available, sign will be skipped for the request and the access token will instead be used via an authorization header. * * More details: https://github.com/tiagosiebler/kucoin-api/issues/2 */ const client = new SpotClient({ apiAccessToken: 'accessTokenHere!', }); try { const result = await client.getBalances(); console.log('result ', JSON.stringify(result, null, 2)); } catch (e) { console.error('Req error: ', e); } // If you later need to set a new access token (e.g. it expired): client.setAccessToken('newAccessTokenHere');} start();
