1. API Description

Domain name for API request:

This API is used to shut down CVM instances in a scaling group.

  • Use the SOFT_FIRST shutdown, which means the CVM will be forcibly shut down if the soft shutdown fails.
  • Shutting down instances in the IN_SERVICE status will reduce the desired capacity, but the desired capacity cannot be less than the minimum value.
  • To use the STOP_CHARGING shutdown, the instances you want to shut down must satisfy the conditions of no charges when shut down.
  • This API supports batch operation. Up to 100 instances can be shut down in each request.

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:
