What is Telegram Bot?
Also called Telegram Bot API.
A Telegram bot is an automated account on Telegram controlled through the platform's bot API. It receives updates either by long polling or by a webhook, and replies with messages, media, inline keyboards, or files. Bots can operate in private chats, groups, and channels, and what they can see inside a group depends on their privacy setting.
A bot is registered with the platform, which issues a token used for every API call. Updates can be pulled over a long lived connection, which needs no public endpoint, or pushed to a webhook URL, which scales better. Bots cannot open conversations with people who have never contacted them, so the first message always comes from the user.
The API offers more interface than plain messaging: inline keyboards attached to a message, a command menu, editing a message after it has been sent, and an inline mode where the bot is invoked from any chat by typing its username. Group behavior is governed by a privacy mode that limits which messages the bot receives unless it is granted broader access.
Telegram is popular for lightweight tools and community automation because setup is quick and no business verification is involved. The same low barrier means users judge legitimacy by the username alone, which is easily imitated. Bots also receive no verified identity for the person on the other side, so anything account specific needs its own authentication step rather than trusting the chat identifier.
Compared with business messaging platforms that gate proactive contact behind approved templates, Telegram places fewer restrictions on what a bot may send to someone who has already started a conversation. That freedom shifts the responsibility onto the operator, since message frequency and relevance are self governed and the only real feedback signal is being blocked.
Key points
- Controlled by a token issued when the bot is registered
- Updates arrive by long polling or by webhook
- The user must message first; bots cannot start cold conversations
- Group visibility depends on the bot's privacy mode
- Chat identity is not verified identity for account actions
In practice
A cycling club runs a Telegram bot in its group chat. Members type a command with a date and the bot posts the ride plan with an inline keyboard for attending or skipping, editing the same message as the counts change. When a member privately asks the bot for their membership status, it sends a one time link to the club site rather than answering from the chat identifier alone.
