## How to find the correct page

If the exact page cannot be found, you can still retrieve the information using the documentation query interface.

### Option 1 — Ask a question (recommended)

Perform an HTTP GET request on the documentation index with the `ask` parameter:

```
GET https://helpdocs.ycloud.com/help-center/whatsapp-accounts-management/create-a-whatsapp-api-account/whatsapp-business-app-coexistence.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

### Option 2 — Browse the documentation index

Full index: https://helpdocs.ycloud.com/help-center/sitemap.md

### Option 3 — Retrieve the full documentation corpus

Full export: https://helpdocs.ycloud.com/help-center/llms-full.txt

Use this to access all content at once and perform your own parsing or retrieval. It will be more expensive.
