The WhatsApp Business API is a messaging solution built for medium to large businesses that need to automate and manage high volumes of WhatsApp conversations. Unlike the WhatsApp Business App, which is meant for small teams, the API connects directly to business systems and supports features like automation, integrations, and multi-agent access.
It doesn't have a user interface. Businesses access it through approved platforms or by integrating it into their own systems using a WhatsApp Business Solution Provider (BSP). Customers must opt in to receive messages, helping maintain trust and compliance. The WhatsApp API enables two-way messaging, automated replies, and bulk communication, making it perfect for support, sales, and updates.
