Senviok API
Email Services · Messaging & SMS · Communications
Senviok is a developer-first communication infrastructure platform built as an African and global alternative to Resend and Twilio, unifying transactional email, SMS, WhatsApp, and OTP authentication tokens under a single REST API, single API key, shared billing wallet, and real-time observability log stream. Designed for reliability, high inbox deliverability, and developer velocity, Senviok eliminates the overhead of managing fragmented vendors, disparate dashboards, and unpredictable foreign exchange billing by providing native Nigerian Naira (₦) and USD ($) billing.
