# filterMapping

상품을 다음 서비스와 동기화할 때 Epsilon Retail Media, 리테일러는 카테고리 및 위치 정보에 내부 값을 사용할 수 있습니다.

예: category\_id:8a\_6b\_vc는 뷰티 카테고리의 고유 식별자입니다.

Epsilon Retail Media 필터 매핑 API를 통해 이러한 내부 값을 UI에 표시하기 위한 사람이 읽을 수 있는 형식으로 매핑할 수 있습니다. 광고주는 이해하기 쉬운 UI에서 상품이 게재 가능한 카테고리 및 위치로 캠페인을 타겟팅할 수 있습니다.

## 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/citrus-filter-mapping-api/filtermapping.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.
