How to Automate OTP Delivery Using WhatsApp Business API with Techto Networks

Introduction

One-Time Passwords (OTPs) are the foundation of secure digital transactions. They’re used everywhere — from login authentication to payment confirmations. Traditionally, SMS was the go-to channel for OTP delivery. However, SMS often faces issues like delays, high costs, and failed deliveries.

With the rise of messaging platforms, WhatsApp Business API has emerged as a better alternative. By partnering with Techto Networks, businesses can automate OTP delivery on WhatsApp, ensuring instant, reliable, and secure authentication.

In this guide, we’ll explore how to set up OTP automation with WhatsApp Business API through Techto Networks, the benefits, compliance considerations, and best practices.
