1. API Description

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

This API is used to change the model of an instance.

  • You can only use this API to change the models of instances whose system disk type is CLOUD_BASIC, CLOUD_PREMIUM, or CLOUD_SSD.
  • Currently, you cannot use this API to change the models of CDH instances.

A maximum of 10 requests can be initiated per second for this API.

We recommend you to use API Explorer
Try it
API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

2. Input Parameters

The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

Parameter Name Required Type Description
Action Yes String Common Params. The value used for this API: ResetInstancesType.
Version Yes String Common Params. The value used for this API: 2017-03-12.
Region No String Common Params. This parameter is not required for this API.
InstanceIds.N Yes Array of String Instance ID(s). To obtain the instance IDs, you can call the DescribeInstances API and find the value InstanceId in the response. The maximum number of instances in each request is 1.
InstanceType Yes String Instance model. Different resource specifications are specified for different models. For specific values, call DescribeInstanceTypeConfigs to get the latest specification list or refer to Instance Types.
ForceStop No Boolean Forced shutdown of a running instances. We recommend you firstly try to shut down a running instance manually. Valid values:
  • TRUE: forced shutdown of an instance after a normal shutdown fails.
  • FALSE: no forced shutdown of an instance after a normal shutdown fails.

    Default value: FALSE.

    A forced shutdown is similar to switching off the power of a physical computer. It may cause data loss or file system corruption. Be sure to only force a CVM to shut off if the normal shutdown fails.
  • 3. Output Parameters

    Parameter Name Type Description
    RequestId String The unique request ID, which is returned for each request. RequestId is required for locating a problem.
