1. API Description

Domain name for API request: clb.tencentcloudapi.com.

This API is used to query the list of CLB instances in a region.

A maximum of 20 requests can be initiated per second for this API.

Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example: clb.ap-shanghai-fsi.tencentcloudapi.com

We recommend you to use API Explorer

Try it

API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

2. Input Parameters

The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

Action	Yes	String	Common parameter. The value used for this API: DescribeLoadBalancers.
Version	Yes	String	Common parameter. The value used for this API: 2018-03-17.
Region	Yes	String	Common parameter. For more information, please see the list of regions supported by the product.
LoadBalancerIds.N	No	Array of String	CLB instance ID
LoadBalancerType	No	String	CLB instance network type: OPEN: public network; INTERNAL: private network.
Forward	No	Integer	CLB instance type. 1: generic CLB instance; 0: classic CLB instance
LoadBalancerName	No	String	CLB instance name.
Domain	No	String	Domain name assigned to a CLB instance by Tencent Cloud. This parameter is meaningful only for the public network classic CLB.
LoadBalancerVips.N	No	Array of String	VIP address of a CLB instance (there can be multiple addresses)
BackendPublicIps.N	No	Array of String	Public IP of the real server bound to a CLB.
BackendPrivateIps.N	No	Array of String	Private IP of the real server bound to a CLB.
Offset	No	Integer	Data offset. Default value: 0.
Limit	No	Integer	Number of returned CLB instances. Default value: 20. Maximum value: 100.
OrderBy	No	String	Sort by parameter. Value range: LoadBalancerName, CreateTime, Domain, LoadBalancerType.
OrderType	No	Integer	1: reverse; 0: sequential. Default value: reverse by creation time \|
SearchKey	No	String	Search field which fuzzy matches name, domain name, or VIP.
ProjectId	No	Integer	ID of the project to which a CLB instance belongs, which can be obtained through the DescribeProject API.
WithRs	No	Integer	Whether a CLB instance is bound to a real server. 0: no; 1: yes; -1: query all.
VpcId	No	String	VPC where a CLB instance resides, such as vpc-bhqkbhdx. Basic network does not support queries by VpcId.

3. Output Parameters

Parameter Name	Type	Description
TotalCount	Integer	Total number of CLB instances that meet the filter criteria. This value is independent of the Limit in the input parameter.
LoadBalancerSet	Array of LoadBalancer	Array of returned CLB instances.
RequestId	String	The unique request ID, which is returned for each request. RequestId is required for locating a problem.
