In detail
The WhatsApp Business API is the interface Meta provides so medium and large businesses can integrate WhatsApp messaging into their own systems. Unlike the consumer WhatsApp app or the small-business WhatsApp Business App, the API has no chat screen — messages are sent and received by software such as a CPaaS platform, a CRM or a custom backend.
With the API a business can send notifications (order updates, one-time passwords, reminders) using pre-approved message templates, run a shared team inbox where several agents work one number, build chatbots and automations, and receive inbound messages through webhooks. The account itself is a WhatsApp Business Account (WABA), which can hold one or more phone numbers.
Businesses usually do not connect directly with Meta. They go through a Business Solution Provider (BSP) or Meta Business Partner that provisions access, handles template approval and adds the tooling on top. InfiQ is an official Meta Business Partner: it provisions API access and layers broadcasts, chatbots, a shared inbox and developer APIs over it.
The API is designed for scale and reliability rather than casual chatting. Business-initiated messages must use approved templates, customers must have opted in, and how many people you can proactively message per day is governed by messaging tiers that rise with your quality rating. That structure is what keeps the channel trusted — and why WhatsApp remains a high-open-rate channel for transactional and marketing messages.
