Telegram Bot API
Telegram's REST API for building bots that can send and receive messages, handle inline queries, manage groups, send files and media, and interact with Telegram users and channels. Free and widely used for agent notification delivery and conversational interfaces.
Best When
An agent needs a free, highly available notification channel or lightweight conversational interface with minimal setup — especially for technical users already on Telegram.
Avoid When
Your team uses Slack/Teams for communication, you need enterprise audit trails, or you expect high-volume per-chat messaging.
Use Cases
- • Sending agent status updates and alerts to Telegram users or channels
- • Building conversational agent interfaces accessible via Telegram
- • Delivering rich notifications with inline keyboards and callbacks
- • Sending files, images, and documents from agent workflows
- • Managing group bots for team notifications and commands
- • Receiving commands from users to trigger agent actions via /commands
Not For
- • Enterprise communication platforms (use Slack or Teams instead)
- • High-volume transactional messaging (rate limits are strict per-chat)
- • Use cases requiring end-to-end encryption by default (only Secret Chats are E2E)
- • Broadcast marketing (Telegram prohibits spam bots)
