The short answer

The free WhatsApp Business app cannot run a true AI chatbot. Automated AI replies need the WhatsApp Business Platform (API), usually through a Business Solution Provider, and Meta charges per delivered message, with 1,000 free delivered service messages per number each month from October 1, 2026. Since January 15, 2026, WhatsApp's terms bar general-purpose AI assistants, but bots that serve your own business are still allowed.

  • Small volume, one person answering: the app's built-in tools are enough to start.
  • After-hours demand, a team or order lookups: move to the Platform through a provider.
  • Keep the bot narrow: a clear scope, human handover and a "never do" list.
  • Test before launch: run 30-50 real past questions through it.

App or Platform: the two ways to automate WhatsApp Business

WhatsApp has two business products, and most confusion about "WhatsApp chatbots" comes from mixing them up.

The WhatsApp Business app is the free app on your phone. It offers a business profile, a catalog, labels, quick replies (saved answers you insert with a shortcut), a greeting message for new contacts and an away message outside your hours. It has no built-in AI chatbot that writes its own answers, so a person still replies.

The WhatsApp Business Platform (often called the API) is built for automation. You reach it through a Business Solution Provider (BSP) or directly through Meta's Cloud API. It lets you connect an AI model, answer automatically, share one number across several agents and link to booking or order systems. In exchange, Meta charges per delivered message, and providers usually add their own fees.

Which route fits your business?

A bot costs time to set up and money to run, so it pays off only when it saves real hours or wins business you are missing.

Pick your route

  • You can comfortably answer every chat yourselfStart with the app: quick replies and an away message.
  • Customers often write after hours and you lose sales or bookingsConsider the Platform with an AI bot that answers FAQs and captures leads.
  • Two or more people answer WhatsAppThe Platform with a shared team inbox avoids missed and duplicated replies.
  • Customers ask "where's my order?" or want to bookThe Platform, connected to your order or booking system.
  • You're not sure yetUse the app for a month and count which questions repeat.

Most very small businesses can start with the app and move later. Your quick-reply texts are not wasted: they become the first draft of the bot's knowledge base.

Moving to the Platform

  • Replies at once, including nights and weekends
  • One number shared by several staff
  • Can look up orders or bookings when connected to your systems
  • AI copes with varied wording, not just fixed keywords

Cons

  • Per-message fees from Meta plus provider fees
  • Business verification and setup take time
  • Templates need approval before you can message customers first
  • Needs ongoing review so answers stay accurate

Route 1: Set up automation in the WhatsApp Business app

If the app fits, the basics are quick to set up. The tools are usually grouped under Business tools in settings, but menu names vary by app version and between Android and iPhone. If something isn't where described, search WhatsApp's help center.

  1. Complete your business profile. Add your address, hours, website, email and a short description so customers find the basics without asking.
  2. Turn on a greeting message. Write a short welcome that says what you can help with and when you usually reply.
  3. Set an away message with your hours. Schedule it outside opening hours and say when a person will get back to customers.
  4. Create quick replies for your top 5-10 questions. List the questions that repeat in recent chats and save an answer for each with a short shortcut.
  5. Use labels to track chats. Tag conversations such as "new order", "pending payment" or "follow up" so nothing slips.

Route 2: Set up an AI chatbot on the WhatsApp Business Platform

This is the route for automated AI replies. Screens differ by provider, but the steps are broadly the same. Settle the phone number question first.

The 12 setup steps

  1. Read the current WhatsApp Business Solution Terms. Confirm your use case is allowed (see the 2026 AI rules section below).
  2. Define a narrow scope. List the 5-10 jobs the bot will do, such as hours, delivery areas and bookings, and what it must hand to a person.
  3. Prepare the prerequisites. You will typically need a Meta business portfolio (formerly Business Manager), a live website, a privacy policy and a phone number for the Platform.
  4. Choose a provider. Use the criteria in the next section and trial it with your own questions. Many providers offer no-code builders; a developer is only needed for custom integrations such as order lookups.
  5. Verify your business and display name. Meta reviews the business and the name customers will see, so match your website and branding.
  6. Connect an approved knowledge source. Load your FAQs, policies, opening hours and price list, plus order or booking lookup if supported. For simpler connections, see how to automate admin tasks without code.
  7. Write the bot instructions. Set tone, scope, hard limits and handover triggers (see the example below).
  8. Set up human handover and a team inbox. Decide who receives handed-over chats and during which hours.
  9. Create and submit message templates. Any message you send first, such as reminders or order updates, needs an approved template.
  10. Collect opt-ins. Add consent to checkout, booking or sign-up forms (see the privacy section).
  11. Test with real questions. Run the pre-launch test below before any customer sees the bot.
  12. Soft-launch and review weekly. Start with limited hours or a subset of customers, and read transcripts weekly for the first month.

How to choose a provider without overpaying

Fees are layered, so ask every provider the same questions, in writing.

CriterionWhat to askWhy it matters
Meta message feesPassed through at cost, or marked up?Markups grow with volume
Platform feeMonthly fee, and what's included?Seats or contacts may cost extra
AI and knowledge baseWhich models? Can I upload FAQs and policies?Answers must use your sources
Human handoverShared inbox with handover rules?Customers can reach a person
Data and DPAWhere are chats stored, how long, used for training? DPA available?Privacy duties under GDPR and similar laws
LanguagesSpanish, Portuguese or others in bot and inbox?Matches your customers
ExportCan I export chats and bot setup?Avoids lock-in

If a provider lets you pick the AI model, our ChatGPT vs Claude vs Gemini comparison can help you weigh the options. Always run a trial with your own real questions before you commit.

Example bot instructions (illustrative)

This is an example to adapt, not a tested template. The principles in how to write AI prompts for business emails apply here too.

EXAMPLE ONLY - adapt to your business.

You are the automated WhatsApp assistant for Rosa's Bakery.
Say you are an automated assistant in your first reply.

Scope: opening hours, location, delivery areas, cake orders
(collect name, date, cake type) and our published price list.
Answer only from the knowledge base. If the answer is not
there, say so and offer a person.

Tone: warm, short, plain. Two to four sentences. Reply in the
customer's language (English, Spanish or Portuguese).

Never: approve refunds, discounts or exceptions; give medical
or allergy guarantees; ask for card numbers or ID; guess
prices, stock or delivery dates.

Hand over to staff when: the customer asks for a person, is
upset, mentions a refund or complaint, repeats a question,
or asks anything outside scope. Tell them a person will reply
and when (Mon-Sat, 8am-6pm).

What a WhatsApp chatbot costs: per-message pricing and the 24-hour window

On the Platform, Meta charges per delivered message. The price depends on the message category and the customer's country, and provider fees come on top.

CategoryWhat it isExampleWhen it's used
MarketingPromotional template"Weekend offer on all cakes"Offers, announcements, re-engagement
UtilityTransactional template"Your order has shipped"Updates on an existing order or booking
AuthenticationOne-time code template"Your login code is 123456"Verifying a customer's identity
ServiceFree-form replyBot answers a delivery questionInside the 24-hour customer service window

The 1,000 free service messages

From October 1, 2026, each business number gets 1,000 free delivered service messages per month; after that, service messages are charged. If your bot mostly answers incoming questions, the allowance may cover part of its replies, but templates are billed separately and provider fees still apply.

Rates vary by country and change over time, so we don't quote them. Check Meta's WhatsApp pricing page (checked 2026-11-02) and your provider's pricing before you budget.

What to automate first

Start with questions answered by your own published information, where a wrong answer is unlikely.

  • FAQs: opening hours, location, delivery areas, returns policy, and prices from your own published list.
  • Order status: only if the bot can look it up in your system. Otherwise, route it to a person rather than guessing.
  • Bookings and appointments: offer available slots and confirm, or send a link to your booking page.
  • Lead capture: collect the customer's name and question, then pass both to staff with the chat history.
  • Spanish or Portuguese replies: have a native speaker review the key answers before launch.

Leave complaints, refunds and anything sensitive to people, at least until you have watched the bot in action for a while.

Hand over to a human: when and how

Design handover in from the start, not as a fallback added later. Hand the chat to a person when:

  • The customer asks for a person, in any wording
  • The message is a complaint or the tone is angry
  • The customer repeats the same question
  • The topic is outside the bot's scope
  • Money is involved: refunds, payment problems, disputed charges
  • Anything sensitive comes up, such as health, legal issues or personal circumstances

When the bot hands over, it should say a person will reply and roughly when, especially outside business hours. Pass the full conversation to your team inbox so the customer doesn't have to repeat themselves. The same human-approval idea runs through our guide to responding to customer reviews with AI.

What you should never let the bot do

Some tasks carry too much risk for automation, however capable the AI model. Put these limits in the bot's instructions and test them before launch.

What the bot should do instead:

  • Refunds, discounts, exceptions: collect details and hand over.
  • Medical, legal or financial questions: decline and offer a person.
  • Card numbers, passwords, ID: point to a secure payment page or form, and never repeat pasted details.
  • Prices, stock, delivery dates: answer only from approved sources, or say the data isn't there.
  • Identity: say it is an automated assistant, first and whenever asked.

WhatsApp requires customers to opt in before you send them business-initiated messages. Ask clearly, for example with a checkbox at checkout that names WhatsApp, and record how and when consent was given.

Then cover the basics:

  • Update your privacy policy to mention WhatsApp, your provider and the AI service that processes messages.
  • Check data handling: where the provider and AI model store and process chats, how long they keep them, and whether chats train models.
  • Share as little as possible with the AI. The bot needs your FAQs, not your customer database. Our guide on whether it's safe to put customer data into ChatGPT explains what to keep out.
  • Set staff rules for who can change the bot and read transcripts, for example with our AI acceptable use policy template.

Test with real customer questions before launch

A bot that handles your sample questions can still fail on real ones, so test with messages customers actually sent.

  1. Collect 30-50 real questions. Pull them from past chats, including messy, misspelled and multilingual messages.
  2. Score every answer. Mark each one: correct, safe, on-brand, and handed over when it should be.
  3. Try to break it. Ask for a refund, a discount or medical advice, paste a card-like number, go off-topic and insist on a person.
  4. Fix and retest. Update the knowledge base and instructions, then rerun the full set, not just the failures.
  5. Soft-launch. Turn the bot on for limited hours or a subset of customers first.
  6. Review transcripts weekly. For the first month, read a sample every week and fix wrong or unhelpful answers.

Stay within WhatsApp's 2026 AI rules

Since January 15, 2026, the WhatsApp Business Solution Terms bar general-purpose AI assistants, meaning services where the AI itself is the product offered to users. Business chatbots that handle support, sales and notifications for your own business are still allowed.

In practice, keep the bot focused on your business. A bakery bot that answers order and opening-hours questions fits; an "ask me anything" assistant does not.

Frequently asked questions

Can I add an AI chatbot to the free WhatsApp Business app?

Not as a true automated AI chatbot. The app offers quick replies, greeting messages and away messages, but a person still reads and sends replies. Automated AI replies need the WhatsApp Business Platform (API), usually through a provider. You can still use an AI assistant outside WhatsApp to draft your quick-reply texts.

How much does a WhatsApp Business chatbot cost?

Meta charges per delivered message by category: marketing, utility, authentication and service. From October 1, 2026, each business number gets 1,000 free delivered service messages per month. Provider fees come on top. Rates vary by country and change, so check Meta's pricing page at developers.facebook.com/docs/whatsapp/pricing and your provider's pricing.

What is the 24-hour customer service window?

When a customer messages you, a 24-hour window opens in which you or your bot can send free-form replies. Outside it, you can only message the customer with an approved template, and only if they have opted in.

Are AI chatbots still allowed on WhatsApp in 2026?

Business chatbots for support, sales and notifications about your own business are allowed. Since January 15, 2026, general-purpose AI assistants, where the AI itself is the product, are barred. Read the current WhatsApp Business Solution Terms before launching.

Can I keep my current WhatsApp Business number?

It depends on Meta's current migration and coexistence options and on your provider. Ask the provider and check Meta's documentation before you start, as you may need to move the number or use a new one.

Do customers need to opt in to receive messages from my chatbot?

Yes, for messages you start, such as templates for reminders or offers. Replies inside a conversation the customer started fall within the service window. Keep a record of how and when consent was given.

Do I need a developer to set up a WhatsApp AI chatbot?

Not for a basic setup. Many providers offer no-code builders where you upload FAQs and write instructions in plain English. A developer helps with custom integrations, such as order lookups from your own systems.

Can the chatbot reply in Spanish or Portuguese?

Most AI models can reply in several languages, including Spanish and Portuguese. Have a native speaker review the key answers, and make sure staff who speak that language can take over when the bot hands a chat to a person.
