Domain name for API request: clb.intl.tencentcloudapi.com.
This API is used to bind one or more backend services to a Cloud Load Balancer listener or layer-7 forwarding rule. Before that, you need to create a related CLB layer-4 listener or layer-7 forwarding rule. For Layer-4 listeners (TCP/UDP), only specify the listener ID. For layer-7 (HTTP/HTTPS) listeners, forwarding rules must be specified through LocationId or Domain+Url.
This API is used to perform asynchronous operations. After it returns a successful result, call the DescribeTaskStatus API with the returned RequestID as an input parameter to check whether this task is successful.
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.
