About Tambua
Tambua is a developer-focused one-time password (OTP) verification API for applications serving users in African markets. Applications request a code and verify it through API calls, with delivery by SMS, WhatsApp, voice, email or M-PESA. Ordered channel fallback can route a code through another channel when delivery fails or times out. The service uses shared sender IDs and provides per-country pricing, signed webhooks, request logs, free test keys and a Node.js SDK. Developers can add verification to account sign-up, login and transaction-confirmation flows in fintech, e-commerce, gaming, logistics and other mobile or web applications. The API is intended for teams that need to verify phone numbers or confirm sensitive actions across African markets; channel availability and charges can vary by destination.
