The WhatsApp Business app is free and fits a business that answers chats by hand from a phone. The WhatsApp Business Platform (the API) is what you need for a real AI bot, automations, a shared team inbox, connection to a CRM and approved message templates at scale. The app has no API access; the platform charges per message for some message types and is usually set up through a provider or an agency.

When to move to the API
- You get more messages than you can answer by hand.
- You want replies at night and on weekends.
- More than one person needs to answer from the same number.
- You want leads and bookings to go straight into your CRM or calendar.
Can I keep my number?
Usually yes. Meta now lets many businesses connect the number they use in the WhatsApp Business app to the platform, and in some setups keep using the app alongside it. Availability depends on the country and the provider, so check before you migrate.

Can I build a bot on the free app?
Only basic automatic messages. A real AI bot needs the platform.
