1. API Description

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

This API (RegisterTargets) is used to bind one or more real servers to a CLB listener or layer-7 forwarding rule. Before using this API, you need to create relevant layer-4 listeners or layer-7 forwarding rules. For the former (TCP/UDP), only the listener ID needs to be specified, while for the latter (HTTP/HTTPS), the forwarding rule also needs to be specified through LocationId or Domain+Url.
This is an async API. After it is returned successfully, you can 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.

2. Input Parameters
