Query parameters

Field

Description

folderId

string

Required field. ID of the folder that the network load balancer belongs to.
To get the folder ID, use a NetworkLoadBalancerService.List request.

pageToken

string

Page token. To get the next page of results, set pageToken to the
ListNetworkLoadBalancersResponse.nextPageToken returned by a previous list request.

filter

string

A filter expression that filters resources listed in the response.
The expression must specify:

  1. The field name. Currently you can only filter by the NetworkLoadBalancer.name field.
  2. An = operator.

Field

Description

networkLoadBalancers[]

NetworkLoadBalancer

List of NetworkLoadBalancer resources.

nextPageToken

string

This token allows you to get the next page of results for list requests. If the number of results
is larger than ListNetworkLoadBalancersRequest.pageSize, use
the nextPageToken as the value
for the ListNetworkLoadBalancersRequest.pageToken query parameter
in the next list request. Each subsequent list request will have its own
nextPageToken to continue paging through the results.
