# Load Balancer Overview

Can be used in a VPC environment.

## Summary

NAVER Cloud Platform is a cloud service built with NAVER's latest computing technology and operational know-how. The application program interface (API) that supports the use of services and solutions provided by NAVER Cloud Platform is called NAVER Cloud Platform API.

## Common Load Balancer settings

The following describes commonly used request and response formats in Load Balancer 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

Load Balancer APIs use NAVER Cloud Platform's common response status codes. For information about the HTTP status codes common to all 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).
