# Modifying Orders

> Modify existing orders in-place without cancelling and re-placing

Modify existing orders in-place without cancelling and re-placing them. The registered provider plugin authorizes each modification with its SDK-managed credential; the user's wallet is not prompted.

<Info>
  The examples on this page use **Hyperliquid** (`provider: 'hyperliquid'`). Replace the `provider` value with any supported DEX from `getProviders()`.
</Info>

## modifyOrders

```typescript theme={null}
const result = await perps.modifyOrders({
  provider: 'hyperliquid',
  address: userAddress,
  modifications: [
    { id: '12345678', price: '94500.00', size: '0.2' },
  ],
});

console.log(result.results);
// [{ action: 'modifyOrder', success: true }]
```

Pass multiple `ModifyOrderInput` entries to modify several orders in one call.
