              Note

              

This guide is based on the GET method. POST method call tests can be performed through Swagger in the API Gateway service of the NAVER Cloud Platform console.

### Request headers

For information about the headers common to all Auto Scaling APIs, see [Auto Scaling request headers](/docs/en/compute-vautoscaling#%EC%9A%94%EC%B2%AD%ED%97%A4%EB%8D%94).

### Request query parameters

You can use the following query parameters with your request:

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `regionCode` | String | Optional | Region code - See [getRegionList](/docs/en/compute-vserver-server-common-getregionlist). - First Region in the query results (default) |
| `autoScalingGroupNo` | String | Required | Auto Scaling Group number - See [getAutoScalingGroupList](/docs/en/compute-vautoscaling-autoscalinggroup-getautoscalinggrouplist). |
| `desiredCapacity` | Integer | Required | Expected capacity - 0-30 - Set to minimum capacity (`minSize`) or more, maximum capacity (`maxSize`) or less. - Automatically adjust the number of servers based on the input value. |
| `responseFormatType` | String | Optional | Format of the response data - `xml` (default) \| `json` |
