The Verify API is a purpose-built solution for sending One-Time Passcodes (OTP) via various channels such as SMS, voice, WhatsApp, email, push, and TOTP. It offers several benefits over Twilio's Programmable Messaging API, including global reliability, unparalleled delivery at scale, and regulatory compliance management. The migration process requires initial setup and swapping out one API call, allowing for the reuse of existing product design and deletion of redundant code. Verify eliminates the need to buy a phone number or store OTPs, instead providing a service that handles localization, translation, and token generation. The API offers customization options, including bringing your own custom code, and includes features such as Fraud Guard protection, managed sending phone number pools, and stateless APIs for handling token generation and checking. Verify is designed to provide a more secure and reliable way of sending OTPs, with features such as automatic blocking of suspicious traffic and support for multiple channels of verification.
