The short answer
Partly. The WhatsApp Business app itself offers a greeting message, an away message and quick replies, and Meta has added its own AI agent inside the app. A third-party chatbot or AI agent cannot plug into the app; it connects through the WhatsApp Business Platform (API). Meta's Coexistence option runs the API and the app on the same number, with limits, and Chatmizer supports it.
Key takeaways
- Built into the app: greeting, away message, quick replies, labels and catalog.
- Meta's own AI agent runs inside the app; outside tools do not.
- Third-party chatbots connect through the official API, not the phone app.
- Coexistence keeps the app and the API on one number; Chatmizer supports it.
- Bots that connect by scanning a WhatsApp Web QR code break WhatsApp's terms.
What can the WhatsApp Business app automate by itself?
The app's automation is deliberately simple, and it is free. For a business answering a handful of chats a day, it may be all you need.
- Greeting message: sent to new customers or after 14 days of no contact.
- Away message: sent outside the hours you set, or always.
- Quick replies: saved answers you insert with a shortcut, still sent by you.
- Labels and a product catalog to organise chats and share items.
Does the WhatsApp Business app have its own AI?
Yes, Meta's. In June 2026 Meta announced Meta Business Agent, an AI that answers customers in the WhatsApp Business app, Messenger and Instagram from the information you give it, free up to a monthly allowance with more in paid Meta plans. Availability can differ by country.
It is Meta's tool, not an open slot: you cannot swap in another company's AI inside the app.
Why do third-party chatbots need the API instead?
The phone app has no public interface for outside software. Meta's official route for software to send and receive WhatsApp messages is the WhatsApp Business Platform, usually called the API, accessed through a provider.
On the API you also get what the app lacks: approved templates after the 24-hour window, a shared team inbox, flows and AI agents that answer anything about your business. The trade-off is cost: Meta charges per template and per reply beyond 1,000 a month per number.
What about bots that connect by scanning a QR code?
Some tools log into WhatsApp Web with your phone's QR code and click through chats automatically. They work until they do not: automating a personal or Business app account this way is against WhatsApp's terms, and the number is what gets banned.
If a tool asks you to scan a WhatsApp Web QR code to "activate the bot", treat that as the warning sign.
What does moving a number to the API involve?
Less than most owners fear. You need a Meta business account (verification raises your sending limits), a phone number that can receive a code, a display name that matches your business, and a payment method for Meta's message fees.
Plan for two things: your phone chat history does not move with a standard migration, and templates for reminders or updates must be approved before you can send them. A provider walks you through the connection itself, usually in under an hour.
Can I keep the app on my phone and use a chatbot too?
With a standard API setup, the number leaves the phone app. Meta's Coexistence option lets a business keep the WhatsApp Business app while the same number is connected to the API, through providers that support it. Chatmizer supports it: messages a teammate sends from the phone appear in the Chatmizer inbox, and the AI agent pauses when a person replies from the app.
Meta lists limits: recent one-to-one chat history can sync but group chats do not, linked devices are unlinked during setup, and throughput is capped. In Chatmizer, WhatsApp group chats can't be managed on these numbers, and read receipts follow the phone app. Not every provider supports Coexistence, so ask before you choose one.
Which option fits you?
A quick way to decide:
- Under 30 chats a day, one person answering: the app's greeting, away and quick replies.
- You want AI help but only use WhatsApp, Instagram and Messenger: try Meta's own agent in the app first.
- Several people answer, you need reminders after 24 hours, or customers also write on TikTok or Telegram: the API with a platform and a shared inbox.
- You are not sure yet: start with the app, write your answers down, and move when the same questions eat an hour a day.

Frequently asked questions
Can ChatGPT answer my WhatsApp Business app messages?
Not inside the app. Since 15 January 2026 WhatsApp's terms ban general-purpose AI assistants on the Business Platform, but an AI that answers your own customers about your business, connected through the API, is allowed.
Is Meta's AI agent free?
Meta says it answers free up to a monthly allowance in the apps, with more replies in paid Meta One plans. Check the current terms for your country.
Will moving to the API delete my chats?
A standard migration does not bring your phone chat history into the API. With Coexistence, recent one-to-one chats can sync. Back up anything important before moving.
Can I use the same number on the app and a chatbot?
Yes, through Coexistence with a provider that supports it, such as Chatmizer. Otherwise, use a second number for the API or move the number fully.
Is the WhatsApp Business app enough for a small shop?
Often, at first. Most shops outgrow it when several people need to answer, when they need reminders after 24 hours, or when the same questions take hours a day.
