Automate OTP verification API for Secure Website Authentication

Our OTP verification API connects Webflow and D7 Messaging through Zapier to deliver secure login OTP and instant lead SMS the moment a new website form submission happens. Turn form signups into verified users, power website authentication, and automate customer notification systems—without writing code.

This no-code integration links Webflow to D7 Messaging using Zapier. When a visitor submits a Webflow form, Zapier automatically triggers D7 Messaging to send an SMS—whether that’s a one-time password (OTP) for account authentication or a personalized instant lead message. It’s a fast, reliable way to verify users, send secure login OTP, and keep new leads engaged from the first touchpoint.
