What is WhatsApp Business API (Business Platform)?

The WhatsApp Business API — now the WhatsApp Business Platform — lets businesses send and receive WhatsApp messages at scale through software instead of a single phone.

Unlike the free WhatsApp Business app, the platform supports multiple agents on one number, chatbots, CRM integration and approved template messages for notifications and marketing. Access is provided through Meta directly or via business solution providers.

Messaging is charged per conversation or message category, with rates that vary by country, and businesses must follow WhatsApp's opt-in and commerce policies.
