1. API Description

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

This API is used to bind an EIP to an instance or the specified private IP of an ENI.
Binding an EIP to an instance (ECM) is essentially to bind it to the primary private IP of the primary ENI of the instance.
When you bind an EIP to the private IP of the specified ENI, if the private IP is already bound to an EIP or public IP, a failure will be reported, and you must unbind it first before you can bind it to a new EIP.
Only EIPs in UNBIND status can be bound to a private IP.

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