Termii API

SMS & Messaging

Termii is a Nigerian-founded communications API platform delivering SMS, voice OTP, email, and WhatsApp messaging with a primary focus on serving Nigerian and African businesses who need the highest possible delivery rates for transactional messages to Nigerian mobile subscribers. As a company founded in Lagos and built by Nigerians, Termii has developed specialized expertise in Nigerian carrier OTP delivery particularly the DND bypass routing for transactional messages that is critical for fintech, healthcare, and authentication applications where OTP delivery failure means user lockout and abandoned transactions.

Termii API Highlights

Termii powers real-time OTP delivery, transactional alerts, and multi-channel messaging for the majority of Nigerian fintech apps.

Different Termii API use cases

  • Nigerian Fintech OTP Delivery:Use Termii's Token API to send OTP verification codes to Nigerian banking app users Termii's DND bypass ensures OTPs reach even DND-registered numbers on MTN, Airtel, Glo, and 9mobile, critical for fintech compliance with CBN 2FA requirements.
  • Multi-Channel OTP with Fallback:Configure Termii to attempt WhatsApp OTP delivery first (free delivery to WhatsApp), then fall back to SMS if the user doesn't have WhatsApp maximizing OTP delivery success rates while minimizing SMS costs.
  • Nigerian E-Commerce Order Notifications:Use Termii bulk SMS to send order confirmation, dispatch, and delivery alerts to Nigerian e-commerce customers leveraging Termii's Nigerian carrier optimization for high delivery rates on promotional messages.
  • Nigerian Platform User Authentication:Replace manual OTP code management with Termii's Token API which generates OTPs, manages TTL (expiry), handles delivery, and verifies token submission reducing development time for authentication flows in Nigerian apps.
