The programmatic interface that lets medium and large businesses send and receive WhatsApp messages at scale.
The WhatsApp Business API (officially the WhatsApp Business Platform) is the programmatic channel Meta offers so businesses can integrate WhatsApp messaging into their own software, CRMs, and automation tools. Unlike the free WhatsApp Business app, the API has no chat interface of its own — it is accessed through code or through a platform built on top of it.
The API supports automated notifications, two-way conversations, chatbots, and routing messages to multiple human agents from a single business phone number. It is designed for higher volumes than the app can handle and unlocks features like message templates, interactive messages, and conversation analytics.
Access is provided either directly through Meta's Cloud API or through a Business Solution Provider (BSP) that layers tooling, billing, and support on top of the raw endpoints.
It is the only compliant way to automate WhatsApp messaging, run chatbots, and serve many agents from one number — the foundation of WhatsApp commerce and support at scale.
Defuser AI is a Meta-Verified provider that gets you onto the WhatsApp Business API without writing code, then layers an agentic AI chatbot, flows, and a unified inbox on top.
