WhatsApp is designed for friends or family to stay in touch and chat either on a one-to-one basis or in a group chat.
WhatsApp Business API has been designed for customers to connect with business owners in a similar, but more formal and controlled way according to WhatsApp's policy.
Businesses can send notifications to customers with opt-in preferences but customers can also contact them with queries and support needs.
