Introduction

Since its launch in 2009, WhatsApp has grown into the world’s most popular messaging app with over 3 billion monthly active users. Today, it’s not just a personal communication tool—it’s also a powerful business platform for customer engagement, marketing, and support.

To support businesses, Meta introduced three versions of WhatsApp:

• The standard WhatsApp app for personal use
