**For main features, enter both the 'Korean feature name' and the 'English feature name'.**

* **Korean feature name:** Up to 10 characters, special characters `:` `.` only allowed, emojis not allowed
* **English feature name:** Up to 15 characters, only the first letter capitalized, special characters `:` `.` only allowed, emojis not allowed

Write the feature name as '\~doing' or a noun form, following Toss UX writing guidelines.

* e.g. 'Check transfer history', 'Send money overseas', 'Check travel reservation history'
* Please write it so the function of the mini app service is clear. If you only use phrases like 'Check reservation', 'Check history', 'Go to view', or 'Watch', users will find it hard to tell what service the function is for.

**Enter the feature name the user will access directly and the destination `intoss://pages` address.**

* If the main feature URL does not open properly, it may be rejected.
* You can set query parameters.

Once you've entered everything, click 'Request review'. The review may take 1–2 business days.

### Check main feature information

You can check the review result in the 'Main Features' tab.

* In the 'Main Features' tab, you can register or edit only the main features separately.
* If you add or edit only the main features separately, only the main features will be reviewed, so it may take 1–2 business days.
* Even when adding or modifying something in an already running mini app, please make sure the main features can be accessed properly.

### Feature setup by development environment

#### Webview

Map the router path to the feature URL.

```
<Route path="/search" element={<SearchPage />} />
```

If you enter the feature URL as `intoss://{appName}/search`you can navigate to that page.

#### React Native

Uses file-based routing similar to Next.js.

`/pages/search.tsx` → `/search` Path mapping → `intoss://{appName}/search`Rendered when entering

For a detailed structure, [Understanding file-based routing](https://appsintoss.gitbook.io/appsintoss-docs/documentation/react-native/screen-navigation/navigation)please refer to it.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://developers-apps-in-toss.toss.im/guide/en/operation/function.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.
