GET https://cvm.tencentcloudapi.com/?Action=ModifyInstancesVpcAttribute
&InstanceIds.0=ins-r8hr2upy
&InstanceIds.1=ins-5d8a23rs
&VirtualPrivateCloud.SubnetId=subnet-dcs9x3gz
&VirtualPrivateCloud.VpcId=vpc-1urkhbj4
&VirtualPrivateCloud.PrivateIpAddresses.0=10.0.0.18
&VirtualPrivateCloud.PrivateIpAddresses.1=10.0.0.19
&<Common request parameters>

Output Example

{
  "Response": {
    "RequestId": "3c14def19-cfes-470e-b241-90787u6jf5uj"
