What it does
The Telegram Bot API is an HTTP interface for bot software. A bot can call methods such as `sendMessage`, receive updates through long polling with `getUpdates`, or register a webhook that Telegram calls when an update arrives. Telegram's tutorial walks through creating a bot with BotFather and obtaining its bot token. This API is for bot accounts, not for building a full Telegram client that logs in as a person.
The official getting-started tutorial begins in Telegram with BotFather, which creates a bot and issues its authentication token. A small first task is to send a reply to a user who has started the bot. The Bot API accepts HTTPS requests, and updates arrive either through repeated getUpdates polling or a webhook endpoint that receives Telegram's HTTPS POST. The two update methods are mutually exclusive while configured; choose polling for a simple local prototype or a webhook when the application has a reachable HTTPS endpoint. These are documented options, not tests performed for this listing.
Telegram stores incoming updates until the bot receives them, but the Bot API documentation says they are not kept for longer than 24 hours. Plan for downtime accordingly, and do not treat the update queue as a permanent event log. The bot token authenticates API requests, so keep it out of client-side code and logs.
The Bot API is narrower than Telegram's client API: it is designed for automated bots and its methods, permissions, and user interactions differ from a full user-session client. The official pages opened for this entry explain the protocol and setup but do not establish a separate API price; no free or paid tier is inferred.
Strengths
- The HTTP interface supports both sending messages and receiving bot updates.
- The official tutorial takes a developer from BotFather to a first bot token and request.
- Developers can choose between long polling and HTTPS webhooks for update delivery.
Watch out for
- The API is for Telegram bots and does not provide the same workflow as a full user client.
- Incoming updates are retained for at most 24 hours, so a bot must handle outages and backlog deliberately.
Best for
- Chatbots, alerts, and workflow assistants that interact with Telegram users.
- Services that can receive user-initiated bot conversations or deliver bot notifications.
- Developers who can protect a bot token and operate polling or an HTTPS webhook endpoint.
