# filterMapping

商品を同期する際、 Epsilon Retail Mediaリテーラーはカテゴリーや位置情報に内部値を使用する場合があります。

例えば、category\_id:8a\_6b\_vc は Beauty カテゴリーの固有識別子です。

Epsilon Retail Media フィルターマッピング API を使用すると、これらの内部値を人間が読める形式にマッピングして UI に表示できます。広告主は、わかりやすい UI で商品が対象となるカテゴリーや位置情報をターゲティングしたキャンペーンを設定できます。

## 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/ja/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.
