Domain name for API request: alb.intl.tencentcloudapi.com.
The SetLoadBalancerSecurityGroups API supports setting (binding and unbinding) security groups for a public network load balancing instance. To query the security groups currently bound to a load balancing instance, use the DescribeLoadBalancerDetail API (https://www.tencentcloud.com/document/api/1822/133711?from_cn_redirect=1). This API uses SET semantics.
For the binding operation, input parameters need to be passed in for all security groups that should be bound to the load balancing instance (bound + new binding).
During unbinding, input parameters need to pass in all security groups bound to a CLB instance after unbinding. To unbind all security groups, omit this parameter or specify an empty array.
A maximum of 20 requests can be initiated per second for this API.
The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.
