Cancel one or more open orders.
The examples on this page use Hyperliquid (provider: 'hyperliquid'). Replace the provider value with any supported DEX from getProviders().

​
USER_AGENT mode

const result = await perps.cancelOrders({
  provider: 'hyperliquid',
  address: userAddress,
  ids: ['12345678'],
});

​
USER mode (manual signing)

import { createAction, executeAction } from '@lifi/perps-sdk';

// Step 1: Build cancel payloads
const { actions } = await createAction(client, {
  provider: 'hyperliquid',
  address: userAddress,
  action: 'cancelOrder',
  params: {
    ids: ['12345678', '12345679'],
  },
});

// Step 2: Sign and submit
const signedActions = await Promise.all(
  actions.map(async (a) => ({
    action: a.action,
    typedData: a.typedData,
    signature: await walletClient.signTypedData({ ...a.typedData }),
  }))
);

await executeAction(client, {
  provider: 'hyperliquid',
  address: userAddress,
  action: 'cancelOrder',
  actions: signedActions,
});
Use the orderId returned from the submit response to cancel orders.
