WhatsApp Business API

The free WhatsApp Business app works fine for a single shop owner replying manually from one phone. The WhatsApp Business API is a different product built for scale: multiple team members or a chatbot can respond simultaneously, conversations integrate with a CRM or booking system, and messages can be sent programmatically — a reminder, an order update, a payment link — without a human typing each one. Access requires going through a Meta-approved Business Solution Provider (BSP) and passing business verification; there is no separate 'API app' to download.

Pricing is conversation-based: Meta charges per 24-hour conversation window, split into business-initiated (marketing, utility, or authentication templates that must be pre-approved) and user-initiated (the customer messages first, keeping the conversation free-form for 24 hours). This matters commercially in Egypt and the GCC, where WhatsApp is the default channel customers already trust — a clinic sending appointment reminders or a retailer confirming an order both rely on approved message templates and the conversation-window pricing model, which a whatsapp ai agents deployment is built around from day one.
