# Cloud Data Streaming Service overview

Available in VPC

Cloud Data Streaming Service is a NAVER Cloud Platform service that allows you to easily deploy, protect, operate, and expand Apache Kafka clusters, an open source platform for real-time streaming data pipelines and application builds. Cloud Data Streaming Service provides APIs for cluster, monitoring, and config group features in RESTful format.

## Common Cloud Data Streaming Service settings

The following describes commonly used request and response formats in Cloud Data Streaming Service APIs.

### Request

The following describes the common request format.

#### API URL

The request API URL is as follows:

```
https://clouddatastreamingservice.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). |
| `Content-type` | Optional | Request data format - `application/json` |

### Response

The following describes the common response format.

#### Response status codes

Cloud Data Streaming Service APIs use NAVER Cloud Platform's common response status codes. For information about the HTTP status codes common to NAVER Cloud Platform, see [Ncloud API response status codes](/docs/en/common-ncpapi#3%EC%9D%91%EB%8B%B5%EC%83%81%ED%83%9C%EC%BD%94%EB%93%9C).
