How the WhatsApp Business Platform works
Automated messages have to go through Meta's WhatsApp Business Platform, not the free WhatsApp Business app. You can connect to Meta's Cloud API directly, or through a Business Solution Provider (BSP) such as Twilio or 360dialog, which adds its own dashboard, support and fees. We recommend direct access when you want the lowest running cost, and a BSP when your team wants a ready-made inbox.
Messages you start, such as reminders, must use a template Meta has approved, in one of three categories: marketing, utility or authentication. When a customer messages you, a 24-hour customer service window opens, and inside it you can reply freely. Customers must have opted in to hear from you on WhatsApp, and we record where and when each opt-in happened.
