Bots allow developers to create customized applications for Telegram users that provide notifications, integrate with other services, and create tools like games, polls and more. Users can interact with bots by sending direct messages or inline queries from the chat interface. The Telegram Bot API provides an HTTP interface for developers to build bots with features like user commands, inline keyboards, and privacy modes. Creating a bot involves registering with BotFather to obtain an API token and making HTTP requests to control the bot functionality.
