Meta Business Agent on WhatsApp, explained

Meta's own AI agent now answers WhatsApp chats for some businesses. It's free to start in the app and about 4–5 US cents a message on the API, by Meta's estimate. On the API, turning it on puts other agents on your number on standby.

The short answer
Meta Business Agent is Meta's own AI agent for WhatsApp. It answers customers from your business details, catalog, files and website, and hands a chat to you when someone asks for a person. In the WhatsApp Business app it's free up to a usage limit; on the API Meta estimates about 4–5 US cents a message. On the API, switching it on puts any other agent on that number on standby.

What Meta Business Agent is

Meta launched it in India on 14 May 2026 as Business AI on WhatsApp, inside the WhatsApp Business app. On 3 June 2026 Meta introduced Meta Business Agent, “expanding our Business Agent to businesses of all sizes globally” across WhatsApp, Messenger and Instagram. Since 1 July 2026 businesses on the WhatsApp Business Platform can use it too, through a provider or directly.

“Globally” is doing some work there. The app's own help center still says the feature is “currently only available in limited countries to select businesses”, so you may go looking for it and find nothing.

What it reads before it answers

In the app, Meta says it can learn from your chats from the past six months, your catalog, documents and photos you upload, and your website, along with the business description, address and hours on your profile. On the API it works from business info, FAQs, files and websites you give it.

A customer can always ask for someone from your team, and the app keeps a list of chats the AI has handed off. On the API the handover is automatic, on signals such as low confidence, a rule violation or a customer asking for a person, and Meta notes that “you do not configure the triggers”. Your own systems can still take a chat back at any time.

What it costs

  • In the WhatsApp Business app: free up to a usage limit Meta doesn't publish. Past it, you wait for the limit to refresh or subscribe to a Meta One plan: Essential, Advanced, Expert or Max, starting at US$14.99, US$49.99, US$149 and US$499 a month. Meta says plans and prices vary by region, and that a plan doesn't guarantee access to the agent.
  • On the API: from 1 August 2026, “one global rate of $2.00 USD per 1 million (M) tokens”. Meta adds that “one message typically consumes 20,000–25,000 tokens, which translates to approximately 4–5 cents (USD) per message”. That single charge covers both the AI and delivering the message. Test messages are free.

For scale: an ordinary reply on the WhatsApp Business Platform costs US$0.0034 in the US and Canada and US$0.0014 in India (see the pricing calculator). That rate doesn't include any AI, though. Use your own agent and you pay Meta for the reply and your agent's provider separately, so compare the totals, not the per-message figures.

Switching it on, off, and why it isn't showing

On: in the WhatsApp Business app, open Tools, choose the AI agent, then accept and confirm. Meta says it can take several minutes to start answering.

Not showing: Meta's answer is blunt. “If you don't see the AI agent option in the Tools tab, Meta Business Agent isn't available for your business yet.” You might be offered a waitlist, which doesn't guarantee access. No waitlist means it isn't offered in your country yet; Meta says that isn't a problem with your account.

Off: Meta's help articles name the menu differently. One says Tools → Your AI agent → AI replies, then pause it for new chats. The other says Tools → Meta Business Agent → Response settings → Disconnect AI, where you can pause replies or disconnect and delete it. Look for whichever your app shows. Replying to a chat yourself pauses the agent in that chat.

Careful
Already using another agent on that number?
On the WhatsApp Business Platform the two can't answer side by side. Meta's conversation routing docs say that once Meta Business Agent is on, it “becomes the primary responder for new conversations” and previous responders on that number move to standby. Meta asks you to check your integrations are ready first. Switch it on just to try it, and whatever was answering before, Zymbler included, goes on standby.

What else changes in the app

  • Away messages and similar automations pause while the AI is handling a chat, and Meta warns greeting messages may be affected.
  • Meta warns it may affect broadcast lists and disappearing messages.
  • Linked devices are disconnected.
  • Customers see a notice that the business uses AI from Meta to generate messages.
  • If you're already talking to a customer, the agent stays out of that chat unless it has been quiet for seven days.

One more line from Meta's help center worth reading before you switch it on: messages in chats where the agent is connected “will still be collected by Meta to improve AI at Meta, even when you mute” the agent. Deleting the agent is what stops it.

Meta's agent or a dedicated one?

If you sell from a catalog, most of your questions are the same handful, and you're happy for Meta to decide when a chat goes to a person, Meta Business Agent is the obvious place to start. It lives where your chats already are, and the app version costs nothing up to its limit.

A dedicated agent makes more sense when:

  • You want your own handover rules without building them. On the API, Meta's automatic triggers are fixed, and adding your own means writing agent instructions and building thread control into your systems. Zymbler hands over when the rules you write say so, with a one-line reason, and emails you when a lead is ready.
  • You want lead notes without building a CRM link. On the API, Meta's agent can qualify leads and send them to your own sales system through a connector you build. Zymbler keeps notes on each customer, gaps marked “not asked yet” and a lead score out of the box, which is what a travel agency or a solar installer runs on.
  • A team works the chats. In Zymbler's shared inbox, anyone can take over a chat and hand it back.

Whichever you pick, pick one per number. The standby rule above means the two can't answer side by side on the API.

One note for clinics: on the API, Meta lists Health among the verticals its agent doesn't serve, with Finance, Government, Alcohol, Gambling, over-the-counter drugs and matrimony services. That's a reason for care with any AI agent on WhatsApp in healthcare.
