# 인증

Brand Pages는 동일한 API 키를 사용합니다 Epsilon RMN 플랫폼; 별도의 키가 필요하지 않습니다.

요청에는 다음이 포함됩니다. `Authorization` HTTP 기본 인증을 사용하는 헤더이며, API 키는 RFC(Request for Comments) 사양에 따라 인코딩됩니다.

```apache
/Authorization: Basic base64(<apiKey>:)
```

위의 RFC 정의 형식 외에도 플랫폼은 기존 API 키 값을 직접 전달하는 방식도 지원합니다. `Authorization`기존 클라이언트 연동과의 호환성을 위한 헤더입니다.

```apache
Authorization: Basic \<existing_api_key>
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.citrusad.com/retail-media-interface/integration/ko/brand-pages/brand-page-retailer-integration-guide/authentication-1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
