Telegram Bot API enables developers to create bots by sending HTTP requests to Telegram's servers. You can use webhook or long polling to receive messages, then respond with text, media, inline keyboards, and payments. The API handles authentication, routing, and delivery automatically.

Webhook pushes updates to your server via HTTP callbacks in real-time, requiring a public HTTPS endpoint. Long polling pulls updates by repeatedly querying Telegram's API, simpler to deploy but higher latency. Choose webhook for production bots needing instant responses; use long polling for development or constrained environments.

Yes. Telegram Mini Apps run Web-based frontends communicating with your backend via Bot API or TDLib. You build interactive UI components, handle authentication through Telegram, and integrate payments and storage. TDLib provides cross-platform client support for more advanced Telegram ecosystem integration.

Bot API includes payment flows through Telegram's native billing system and file transfer APIs for media handling. Developers configure payment providers, define product details, and receive payment notifications via webhook or long polling. File transfer uses HTTP multipart upload for media and document handling.

Deployment requires HTTPS endpoints for webhook, environment setup for long polling, and secure storage for API tokens. Mini Apps need a web server hosting the frontend and backend infrastructure supporting Bot API or TDLib calls. Consider scaling webhook handlers and monitoring message throughput for production reliability.

Bot API is sufficient for most bots, webhooks, inline keyboards, and payments. Use TDLib only if you need cross-platform client libraries, lower-level protocol control, or building custom Telegram clients. Bot API is simpler to deploy and covers standard bot and Mini App workflows.
