### Request query parameters

You can use the following query parameters with your request:

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `regionCode` | String | Optional | Region code of the load balancer instance whose list you want to view - First Region of the getRegionList search result (default) - See [getRegionList](/docs/en/compute-vserver-server-common-getregionlist) |
| `vpcNo` | String | Optional | VPC number of the load balancer instance whose list you want to view - See [getVpcList](/docs/en/networking-vpc-vpcmanagement-getvpclist) |
| `loadBalancerTypeCode` | String | Optional | Load balancer type - `APPLICATION` \| `NETWORK` \| `NETWORK_PROXY` |
| `loadBalancerNetworkTypeCode` | String | Optional | Load balancer network type - `PUBLIC` \| `PRIVATE` |
| `loadBalancerInstanceNoList.N` | List[String] | Optional | List of numbers of the load balancer instances - `loadBalancerInstanceNo` can be obtained through [getLoadBalancerInstanceList](/docs/en/networking-vloadbalancer-loadbalancer-getloadbalancerinstancelist) - <E.g.> loadBalancerInstanceNoList.1=1234&loadBalancerInstanceNoList.2=2345 |
| `pageNo` | Integer | Optional | Page number in paged results |
| `pageSize` | Integer | Conditional | Number of results to display on a page - It is required when entering `pageNo` |
| `sortList.N.sortedBy` | String | Optional | Sort by - `loadBalancerName` - `loadBalancerName`: load balancer name - <E.g.> sortList.1.sortedBy=loadBalancerName |
| `sortList.N.sortingOrder` | String | Optional | Sort order - `ASC` (default) \| `DESC` - `ASC`: ascending - `DESC`: descending - <E.g.> sortList.1.sortingOrder=DESC |
| `responseFormatType` | String | Optional | Response result format - `xml` (default) \| `json` |
