1. API Description

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

This API (CreateLoadBalancer) is used to create a CLB instance. To use the CLB service, you first need to purchase one or more instances. After this API is called successfully, a unique instance ID will be returned. There are two types of instances: public network and private network. For more information, see the product types in the product documentation.
Note: (1) To apply for a CLB instance in the specified AZ and cross-AZ disaster recovery, please submit a ticket; (2) Currently, IPv6 is supported only in Beijing, Shanghai, and Guangzhou regions.
This is an async API. After it is returned successfully, you can call the DescribeLoadBalancers API to query the status of the instance (such as creating and normal) to check whether it is successfully created.

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
