WhatsApp Business API
Updated
Quick answer: The WhatsApp Business API (officially the WhatsApp Business Platform) is Meta's interface that lets businesses send and receive WhatsApp messages through software instead of a phone app. It supports many agents on one number, chatbots, bulk template messages to opted-in customers, and integrations with CRMs and online stores. Businesses use it through a provider such as Advertz, and Meta charges per delivered template message.
Meta's official way for businesses to send and receive WhatsApp messages at scale.
Unlike the free WhatsApp Business app, the API has no interface of its own. A platform connects your phone number to Meta and gives you an inbox, campaigns, chatbots and reporting on top.

- Free-form replies are allowed inside the 24-hour customer service window
