WhatsApp Business API vs the Business app
The app is manual chat on one phone. The API is for bots, teams, and official automation.
The Business app
Free, on your phone, fine for a solo owner. Not a real bot.
The Business API
Official platform for chatbots, templates and staff. You still need software such as Nexlution to run bookings.
Green tick
Official verification is a trust badge. It does not replace a good booking flow.
FAQ
Is the API free?
Meta bills by message type and country. The bot platform has its own subscription.
