Telegram APIs

Telegram provides three APIs for developers: the Bot API for creating bots that use Telegram messages as an interface, the Telegram API and TDLib for building customized Telegram clients, and the Gateway API for sending verification codes through Telegram instead of SMS. Telegram Widgets can also be added to websites, and designers can create Animated Stickers, Emoji, and Custom Themes.

The Bot API communicates with an intermediary server over a simple HTTPS interface, handling encryption and communication with the Telegram API, and includes a Payments API for accepting payments. TDLib is an open-source library supporting Android, iOS, Windows, macOS, Linux, and other systems, compatible with virtually any programming language, that manages network implementation, encryption, and local data storage. The Telegram API documentation covers user authorization, two-factor authentication, QR code login, passkeys, error handling, data center handling, updates, push notifications, channels, groups, forums, statistics, file transfer, pagination, calls, secret chats, and end-to-end encryption. AI features are powered by Cocoon, and bots support commands, buttons, inline queries, games, mini apps, affiliate programs, attachment menus, AI bots, guest mode, and bot-to-bot communication.

The Bot API and Telegram API are available free of charge, and the Gateway API is free to test. The Telegram API requires registering an application in the system.
