WhatsApp Business API for your business: what it is and how to start without a fuss

The official WhatsApp API lets you answer and notify from a business number with clear rules. What it is, what you need and what it does not do.

If your business already takes appointments over WhatsApp, sooner or later you need to tidy up the channel: one number, several people, a history and answers at any hour. That is what Meta's official WhatsApp Business API is for.

What changes compared with the app

With the API, the business number connects to a platform and no longer depends on one phone. Several people can reply from one inbox and an assistant can handle the usual questions. The history is kept and nothing stays on anyone's phone.

Rules worth knowing

You can reply freely during the 24 hours after the customer's last message. To write first, WhatsApp requires approved templates, and only to people who agreed to receive messages. That protects you too: no mass sending without permission.

What you need

A Meta business account, a number you can dedicate to the business and the guided sign-up. In Axon you connect in Meta's own window, step by step, and every detail is checked before it is saved.

What the assistant can do

It answers from the real data of your web and your documents. If the customer wants to book, it proposes a time and waits for their confirmation: the booking is made only when the person says yes. When needed it hands over to your team.

What it does not do

It does not invent prices, give medical or legal advice, or write to anyone who has opted out. The word STOP is always respected.
