## What is TelegramBot?

Telegram does not document this user agent. It is widely reported to fetch link previews for URLs sent in Telegram chats, but Telegram has not confirmed that.

Fetches a page when someone shares its link, to draw the preview card. Blocking it breaks your previews in that app.

## Should you block TelegramBot?

Allow it. Blocking it breaks the preview card when someone shares your link.

## How to block TelegramBot in robots.txt

Telegram documents no robots.txt token for TelegramBot that we could confirm, so we don’t suggest one here. Block it at your server or firewall by user agent instead.

## How to verify a request is really TelegramBot

Anyone can send any user agent, so the string alone proves nothing.

Telegram publishes no IP ranges or DNS names for TelegramBot that we could find, so there is no reliable way to tell a real TelegramBot from a scraper using its user agent.

## See when TelegramBot reads your site

Bots don’t run JavaScript analytics, so a script tag never sees them. invisit records crawler reads on the server instead, through its server SDK or a Cloudflare Worker, and shows which bots read which pages, next to your visitors.
