Question 1

What does Termii do?

Accepted Answer

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.

The Termii SMS API reaches all four Nigerian mobile networks (MTN, Airtel, Glo, 9mobile) with NGN-denominated pricing and delivery infrastructure optimized for the Nigerian telecom environment. Termii's routing intelligence distinguishes between message types — automatically applying transactional routes that bypass DND for OTPs and critical notifications, while routing promotional messages through standard channels with DND compliance. This automatic routing optimization reduces developer complexity and ensures the right delivery path is used for each message type.

OTP delivery is Termii's core product and competitive strength. Termii Token — their OTP management API — provides a complete managed verification flow: request a token, Termii generates and sends it via SMS or voice, the developer submits the user-entered code to verify. Termii handles code generation, expiry (configurable 1-60 minutes), multi-channel fallback, and verification logic. Nigerian fintech apps, e-commerce platforms, and healthcare systems can integrate Termii Token to implement secure phone verification without building any OTP infrastructure themselves.

Voice OTP through Termii calls the recipient's Nigerian number and reads the code via text-to-speech. This is deployed as an automatic fallback when SMS OTP fails to deliver within the configured timeout — Termii's system can automatically retry via voice call if SMS delivery is not confirmed. For Nigerian banking apps where every failed OTP leads to a lost transaction or a customer service call, the voice fallback measurably improves verification success rates.

WhatsApp Business messaging through Termii enables sending WhatsApp template messages to Nigerian customers — order notifications, delivery updates, account alerts, and OTP codes through WhatsApp. Termii's WhatsApp API integration means Nigerian businesses can add WhatsApp to their notification channels without a separate Meta Business API engagement. WhatsApp delivery of OTPs achieves extremely high open rates compared to SMS in Nigeria, where WhatsApp notifications are typically checked within minutes.

Email notifications through Termii cover transactional email delivery for Nigerian applications — verification emails, password resets, system alerts, and notification messages. The Termii API supports HTML and plain text email, with sender domain customization for branded from-addresses.

Termii provides a developer sandbox for testing API calls against simulated Nigerian network responses without real delivery costs, enabling Nigerian developers to build and test complete notification flows before going live. SDKs are available for JavaScript, Python, and PHP. Pricing is freemium with a free trial credit and paid plans in NGN for production use. Termii's developer sandbox environment and comprehensive API documentation make it one of the easiest Nigerian communications platforms to onboard, with support available through their Lagos-based team. Nigerian fintech startups consistently rate Termii as the top Nigerian-specific OTP delivery solution for their authentication infrastructure.
