```

Fills order's quote, fully or partially (whichever is possible)

**Parameters:**[**​**](https://docs.1inch.io/docs/limit-order-protocol/smart-contract/OrderRFQMixin#parameters-2)

| Name           | Type                       | Description                          |

### fillOrderRFQToWithPermit[​](https://docs.1inch.io/docs/limit-order-protocol/smart-contract/OrderRFQMixin#fillorderrfqtowithpermit) <a href="#fillorderrfqtowithpermit" id="fillorderrfqtowithpermit"></a>

```javascript
function fillOrderRFQToWithPermit(
  struct OrderRFQMixin.Order order,
  bytes signature,
  uint256 makingAmount,
  uint256 takingAmount,
  address target,
  bytes permit
) external returns (uint256, uint256)
```

Fills Same as `fillOrderRFQ` but calls permit first, allowing to approve token spending and make a swap in one transaction. Also allows to specify funds destination instead of `msg.sender`

See tests for examples
