// order pending asset
authClient.trade().orderPending({ "market": "BDXBTC", "offset": 0, "limit": 2, "user_id": 84 });
// order pending details
authClient.trade().orderPendingDetails({ "market": "BDXBTC", "order_id": 84 });

// finished order details
authClient.trade().finishedOrderDetails({ "order_id": 84 });

WebSocket

const { WebsocketClient } = require('@bdxi/node-beldex-api');
const wss = new WebsocketClient();

wss.connect();
wss.login(api-key, secret, passphrase);

// State subscription
wss.send({ "method": "state.subscribe", params: ["BDXBTC"] });
// deals subscription
wss.send({ "method": "deals.subscribe", params: ["BDXBTC"] });
// kline subscription
wss.send({ "method": "kline.subscribe", params: ["BDXBTC", 60] });
// depth subscription
wss.send({ "method": "depth.subscribe", "params": ["BDXUSDT", 50, '0'] });
// depth query
wss.send({ "method": "depth.query", params: ["BDXBTC", 50, '0'] });
// kline query
wss.send({ "method": "kline.query", "params": ["BDXBTC", 1575539107, 1580723167, 3600] });
// order query
wss.send({ "method": "order.query", params: ["BTCUSDT", 0, 50] });
// order history
wss.send({ "method": "order.history", "params": ["BDXBTC", 1580636703, 1580723103, 0, 50] });
// order subscription
wss.send({ "method": "order.subscribe", "params": ["BDXUSDT"] });
// asset query
wss.send({ "method": "asset.query", "params": ["BDX", "BTC"] });
// asset subscription
wss.send({ "method": "asset.subscribe", "params": ["BDX", "BTC"] });

Listen to subscription

All the subscriptions can be handled using onMessage function. The subscription can be differentiated using the method value from the response data.

wss.onMessage(data => {
    console.log(data);
});
