Overview

Telegram MTProto is the full-featured Telegram API that lets you build custom Telegram clients and read/write data for real user accounts, not just bots. It uses Telegram's own encrypted MTProto protocol, which requires OAuth authentication and a dedicated client library. This API is best for advanced developers building full Telegram clients or user-level automation.
