Domain name for API request: as.intl.tencentcloudapi.com.

This API is used to modify the target rule attributes of the CLB in the scaling group.

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

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.

Parameter Name	Required	Type	Description
Action	Yes	String	Common Params. The value used for this API: ModifyLoadBalancerTargetAttributes.
Version	Yes	String	Common Params. The value used for this API: 2018-04-19.
Region	Yes	String	Common Params. For more information, please see the list of regions supported by the product.
AutoScalingGroupId	Yes	String	Scaling group ID. obtain the scaling group ID by logging in to the console (https://console.tencentcloud.com/autoscaling/group) or calling the api DescribeAutoScalingGroups (https://www.tencentcloud.com/document/api/377/20438?from_cn_redirect=1), and retrieve AutoScalingGroupId from the returned information.
ForwardLoadBalancers.N	Yes	Array of ForwardLoadBalancer	Specifies the list of load balancers whose target rule attributes need modification, with a list length limit of 100. can be obtained through the DescribeLoadBalancers api.

3. Output Parameters

Parameter Name	Type	Description
