Kraken Spot websocket API JavaScript example for the Siebly Kraken 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.

For example, using `WS_KEY_MAP.spotPrivateV2` indicates that the subscription is for Spot private topics, as shown below. * * Refer to WS_KEY_MAP in the source code for all available WsKey options. */ const client = new WebsocketAPIClient( { apiKey: account.key, apiSecret: account.secret, }, customLogger, ); /** * The below examples demonstrate how you can subscribe to private topics. * * Note: while the documentation specifies "token" as a required parameter, the SDK will automatically: * - fetch the token using your API key/secret, * - manage token caching/refreshing, * - include the token in the request for you. * * So you do NOT need to manually fetch or provide the token when subscribing to private topics. * * Do note that all of these include the "spotPrivateV2" WsKey reference. This tells the WebsocketClient to use the private "wss://ws-auth.kraken.com/v2" endpoint for these private subscription requests. */ try { const addOrderResponse = await client.submitSpotOrder({ order_type: 'limit', side: 'buy', limit_price: 26500.4, order_userref: 100054, order_qty: 1.2, symbol: 'BTC/USD', }); console.log('addOrderResponse: ', addOrderResponse); const addOrderConditionalResponse = await client.submitSpotOrder({ order_type: 'limit', side: 'buy', order_qty: 1.2, symbol: 'BTC/USD', limit_price: 28440, conditional: { order_type: 'stop-loss-limit', trigger_price: 28410, limit_price: 28400, }, }); console.log('addOrderConditionalResponse: ', addOrderConditionalResponse); const addOrderTriggersResponse = await client.submitSpotOrder({ order_type: 'stop-loss', side: 'sell', order_qty: 100, symbol: 'MATIC/USD', triggers: { reference: 'last', price: 10.0, price_type: 'pct', }, }); console.log('addOrderTriggersResponse: ', addOrderTriggersResponse); const amendOrderResponse = await client.amendSpotOrder({ cl_ord_id: '2c6be801-1f53-4f79-a0bb-4ea1c95dfae9', limit_price: 10000, order_qty: 1.2, }); console.log('amendOrderResponse: ', amendOrderResponse); const amendOrderPostOnlyResponse = await client.amendSpotOrder({ order_id: 'OAIYAU-LGI3M-PFM5VW', order_qty: 1.2, limit_price: 1100.3, deadline: '2025-11-19T09:53:59.050Z', post_only: true, }); console.log('amendOrderPostOnlyResponse: ', amendOrderPostOnlyResponse); const cancelOrderResponse = await client.cancelSpotOrder({ order_id: ['OM5CRX-N2HAL-GFGWE9', 'OLUMT4-UTEGU-ZYM7E9'], }); console.log('cancelOrderResponse: ', cancelOrderResponse); const cancelAllResponse = await client.cancelAllSpotOrders(); console.log('cancelAllResponse: ', cancelAllResponse); const cancelAllOrdersAfterResponse = await client.cancelAllSpotOrdersAfter({ timeout: 100, }); console.log('cancelAllOrdersAfterResponse: ', cancelAllOrdersAfterResponse); const batchAddResponse = await client.batchSubmitSpotOrders({ deadline: '2025-11-19T09:53:59.050Z', orders: [ { limit_price: 1010.1, order_qty: 1.2, order_type: 'limit', order_userref: 1, side: 'buy', }, { limit_price: 1100.3, order_qty: 1.2, order_type: 'limit', order_userref: 2, side: 'sell', stp_type: 'cancel_both', }, ], symbol: 'BTC/USD', validate: false, }); console.log('batchAddResponse: ', batchAddResponse); const batchCancelResponse = await client.batchCancelSpotOrders({ orders: ['OM5CRX-N2HAL-GFGWE9', 'OLUMT4-UTEGU-ZYM7E9'], }); console.log('batchCancelResponse: ', batchCancelResponse); } catch (e) { console.error('Req error: ', e); }} start(); We use essential cookies and optional analytics.
