WhatsApp Business API
The WhatsApp Business API (via the WhatsApp Business Platform) is Meta's official interface for companies to send and receive WhatsApp messages programmatically at scale.
It's how businesses run verified, multi-agent, system-integrated WhatsApp operations, as opposed to the WhatsApp Business app, which is designed for a single small business on a phone. Access runs through Meta Business Partners and official onboarding like Embedded Signup.
