What’s the difference between the WhatsApp Business API and the WhatsApp Business App?

The WhatsApp Business API is designed for medium to large businesses needing scalable communication solutions, supporting automation, chatbots, and integration with systems like CRM or ERP. The WhatsApp Business App, available for iOS and Android, is better suited for small businesses with a single owner, offering basic features but lacking automation or API capabilities.
