Migrating From Twilio to Prelude: A Technical Guide

The article provides a comprehensive guide on migrating from Twilio's messaging and verification services to Prelude's unified Verify API, which offers a streamlined approach to managing the entire OTP lifecycle with increased efficiency and lower costs. Businesses typically experience a 20-30% increase in conversion rates and 30-40% reduction in SMS costs due to Prelude's built-in machine learning-based fraud prevention, which requires no additional tooling. The migration involves replacing Twilio's Programmable Messaging and Verify services with a single Prelude API, offering a simpler integration process by eliminating ServiceSID and channel selection logic. The process is generally low-risk, with most teams completing the transition in a single sprint, and includes the setup of fraud signals and webhook signature verification for enhanced security. Prelude's automatic multi-channel routing optimizes delivery rates, while its real-time dashboard allows for monitoring conversion and block rates, providing a clear view of performance improvements post-migration.
