Everything you need to know about the WhatsApp Business API — what it is, what it costs, how to get it, and how it differs from the free WhatsApp Business app.
TL;DR
The WhatsApp Business API is the enterprise version of WhatsApp, built for businesses that communicate with customers at scale. Unlike the free WhatsApp Business App — which runs on a single phone and can only be used by one person at a time — the API gives an entire team access, supports automation through an AI chatbot, and connects to your CRM, webshop, or helpdesk software.
You likely need the API if your business fits one or more of these: multiple agents need to handle WhatsApp conversations at once, you regularly send order confirmations or notifications at scale, or you want recurring questions answered automatically instead of an agent typing the same answer every time.
Since 1 July 2025, Meta no longer charges per conversation. Instead, you pay per delivered template message, with a rate that depends on the template category and the recipient's country. What you pay for:
Utility and authentication templates get lower rates at higher monthly volumes (volume tiers). On top of Meta's costs, you pay a monthly fee to your BSP for the software around it — with Bugalou that starts at €49/month, including the shared inbox, AI chatbot, and automations. Want a concrete estimate based on your message volume?
Meta doesn't give businesses direct access to the API — the connection always runs through a Business Solution Provider (BSP). The process roughly involves five steps:
Bugalou handles this entire process for you: from WABA setup to number registration and your first template approval, so you can start messaging on WhatsApp within days.

With Meta's WhatsApp Business Calling API, customers can call your business number straight from WhatsApp — and you answer in your customer service software instead of on one phone. Incoming calls (a customer calls you) are free with Meta. Outgoing calls are charged per minute and require the customer's permission first.
