Introduction

Chaari is cloud SMS infrastructure for developers: you send transactional and campaign messages over a REST API, track delivery, and automate with webhooks. Coverage today includes Chad (Airtel Tchad, Moov Africa Tchad), with expansion planned across Sub-Saharan Africa.

You integrate Chaari from your backend. Chaari does not contact your end recipients directly—you do, using your own product flows and consent practices.

Who this is for

Backend engineers who already work with REST, JSON, and Bearer API keys, and who need reliable SMS in African markets (often mobile-first and variable connectivity).

What you can build

• One-time passwords (OTPs) and account verification
• Transactional alerts (payments, appointments, security)
• Promotional and bulk campaigns with reporting
• Delivery-driven workflows using webhooks
