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 NAS APIs, see [NAS request headers](/docs/en/nas-overview-classic#%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 |
| --- | --- | --- | --- |
| `nasVolumeInstanceNo` | String | Required | Unique number of the NAS volume instance - See [getNasVolumeInstanceList](/docs/en/compute-server-getnasvolumeinstancelist) |
| `snapshotVolumeConfigurationRatio` | Integer | Required | Set the percentage of snapshot allocation in the volume (%) - 0 - 99 - If the snapshot capacity exceeds the set percentage of capacity, it deletes past snapshots first - Setting to 0 disables snapshots |
| `snapshotVolumeConfigDayOfWeekTypeCode` | String | Optional | Enable automatic snapshot creation and set the frequency`-1` (daily) \| `0` (Sunday) \| `1` (Monday) \| `2` (Tuesday) \| `3` (Wednesday) \| `4` (Thursday) \| `5` (Friday) \| `6` (Saturday) - Invalid if snapshot allocation percentage is zero - Create automatically by day of week as set within snapshot capacity limits |
| `snapshotVolumeConfigTime` | Integer | Conditional | Execution time (hour) for automatic snapshot creation - 0 - 23 - Setup required if automatic snapshot creation is enabled |
