Title: Leveraging Telegram for Effective Communication and Community Building in Sri Lanka: The “Badu” Case Study and Best‑Practice Guidelines

Abstract Telegram, a cloud‑based instant‑messaging platform, has gained rapid traction in Sri Lanka due to its speed, security, and rich API ecosystem. This paper examines how the “Badu” initiative—a grassroots network of small‑business owners, local NGOs, and cultural groups—has harnessed Telegram to foster engagement, streamline operations, and amplify impact. By analysing Badu’s deployment of channels, groups, bots, and payment integrations, we distill a set of best‑practice recommendations that can be adopted by other Sri Lankan organisations seeking to maximise the benefits of Telegram while mitigating common pitfalls.

1. Introduction 1.1 Background

Over 12 million Sri Lankans (≈ 55 % of the population) use smartphones; 70 % of them have installed at least one messaging app. Telegram’s end‑to‑end encrypted secret chats, large file‑size limits (2 GB), and robust bot framework make it a compelling choice for both personal and professional communication.

1.2 Why “Badu”?

“Badu” (Sinhala: බදු) loosely translates to “exchange” or “trade”. The Badu network began in 2022 as a WhatsApp‑based community of micro‑entrepreneurs in the Kandy district. In 2023 it migrated to Telegram to overcome WhatsApp’s limitations on member count, media size, and automation.

1.3 Objectives of the Paper

Document Badu’s Telegram architecture and usage patterns. Identify challenges encountered and solutions adopted. Derive actionable best‑practice guidelines for Sri Lankan organisations.

Product Launch – Marketing team schedules a carousel post in the channel. Inquiry – User taps the “Buy” button → BaduBot asks for quantity & address.
