# Cloud DB for MSSQL (VPC) overview

Available in VPC

You can easily build and automatically manage MSSQL databases with Cloud DB for MSSQL. It is a fully managed cloud database service that operates stably through NAVER's optimization settings, and it automatically recovers in case of failure occurrence. Cloud DB for MSSQL provides APIs for database management features in RESTful form.

## Common Cloud DB for MSSQL settings

The following describes commonly used request and response formats in Cloud DB for MSSQL APIs.

### Request

The following describes the common request format.

#### API URL

The request API URL is as follows:

```
https://ncloud.apigw.ntruss.com
```

#### Request headers

The following describes the request headers.

| Field | Required | Description |
| --- | --- | --- |
| `x-ncp-apigw-timestamp` | Required | This is the number of milliseconds that have elapsed since January 1, 1970 00:00:00 UTC. - Request is considered invalid if the timestamp differs from the current time by more than 5 minutes. - Unix timestamp format. |
| `x-ncp-iam-access-key` | Required | Access key issued on NAVER Cloud Platform - Issue and check access key: See [Create authentication key](/docs/en/common-ncpapi). - Issue and check access key for sub account: See [Create sub account](https://guide.ncloud-docs.com/docs/en/subaccount-use#%EC%84%9C%EB%B8%8C-%EA%B3%84%EC%A0%95-%EC%83%9D%EC%84%B1). |
| `x-ncp-apigw-signature-v2` | Required | Base64-encoded signature that encrypts the request information with a secret key that maps to the access key issued on NAVER Cloud Platform, using the HMAC encryption algorithm (HmacSHA256). - Issue and check secret key: See [Create authentication key](/docs/en/common-ncpapi). - Create signature: See [Create signature](/docs/en/common-ncpapi). |

### Response

The following describes the common response format.

#### Response status codes

Cloud DB for MSSQL APIs use NAVER Cloud Platform's common response status codes.
