This guide helps you integrate the WhatsApp Gateway into your application to send template-based messages and OTPs to your users via WhatsApp.
WhatsApp Gateway is a service that allows businesses to send WhatsApp messages to their users through the WhatsApp Business Platform. All messages are based on pre-approved templates — either utility templates for transactional messages or authentication templates for OTP delivery.

- Quick start — prerequisites, environments, and authentication
