The WhatsApp Business Platform is Meta's offering for medium and large businesses. It is distinct from the free WhatsApp Business App, which targets small businesses operating from a single phone.
The platform includes the WhatsApp Cloud API, message templates, conversation-based pricing, the customer service window, and management tools for phone numbers and business accounts.
Most businesses use the platform through a Business Solution Provider, which packages the underlying API into a usable dashboard with campaigns, automations, a shared inbox, and analytics.
