# Web key (VKEY)

**VKEY** links your Telegram user to the website (same subscription row).

Format: `VKEY-` + 16 hex characters (example shape: `VKEY-a1b2c3d4e5f67890`).

## Get a key

1. Active Pro or trial in Telegram.
2. Hub bot: `/mykey`.
3. Tap **Open website** — or copy the key and paste on [voltarb.com/account](https://voltarb.com/account).

Checkout and Account flows can also deep-link:

`https://t.me/voltarb_pro_bot?start=link_VKEY-…`

## What syncs

* Pro / Free tier for the web app
* Filters, blacklist, watchlist with the personal bot
* Web invoices and payment status for your account

## Security

* **Never** post your VKEY in public chats, screenshots for strangers, or GitHub issues
* Treat it like a password for your VoltArb account
* If leaked, contact support and regenerate via `/mykey` if available

## Troubleshooting

| Problem                       | Fix                                                      |
| ----------------------------- | -------------------------------------------------------- |
| Key rejected                  | Copy full string including `VKEY-`. No spaces.           |
| Site still Free after Pro pay | Wait for confirm; refresh Account; re-open `/mykey` link |
| Filters differ web vs bot     | Confirm same VKEY session; re-save filters once          |

# 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://voltarb.gitbook.io/voltarb-docs/english/web-key.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.
