The Twilio Verify API is a powerful tool for sending and checking one-time passcodes, allowing developers to focus on business logic instead of user verification. To validate the success of a Verify implementation, it's essential to plan a test run, use best practices, design a good user experience, and measure success criteria such as conversion rate improvement, time to convert, support cost reduction, and overall cost reduction. The article provides guidance on how to update code, take advantage of features like redundant routing, and define success criteria before implementing Verify in production with confidence.
