A WhatsApp AI agent for business is software that reads your customers' WhatsApp messages and replies using your own information. Some also act for the customer, such as checking an order or booking a slot. You can switch on Meta's own agent, Meta Business Agent, which Meta offers in the WhatsApp Business app and, for developers, on its Business Platform. Or you can build a custom agent on the WhatsApp Business Platform that connects to your own systems. Either way it must follow Meta's rules, below.
Checked against Meta's pages on 9 October 2026.
Two ways to get one
Meta Business Agent. Meta's product page says it can answer questions about business info, products, pricing, discounts, payment and shipping, recommend products, and ask for customer details. It has four controls: knowledge, personality, audience and handoff. Turn it on from the Tools section of the WhatsApp Business app, with the number registered in that app.
A custom agent. Runs on the WhatsApp Business Platform. Your code receives each message through the Cloud API, decides what to do, and replies. You choose the AI model, its knowledge and the systems it can touch. We build these. Pickup is our concept for an AI phone agent, not client work.
Meta also has a developer product, the Meta Business Agent Platform, where you configure an agent with knowledge, instructions, your own APIs and handoff to your app. The real question is how much control you want.
Meta Business Agent: what Meta says
- Availability. The product page says "available to eligible businesses in select markets, with additional markets launching soon". Meta's May 2026 announcement says Business AI on WhatsApp is rolling out in India, in all native Indian languages, from the Tools tab. We read this as the same feature. For the Platform version, the docs require an eligible country, and the pages we opened do not name India. Check eligibility before you plan around it.
- What it can do. Per the capabilities page, the Platform agent answers from business info, FAQs, files and websites, and takes actions through connectors, such as looking up an order or booking an appointment. It hands off when confidence is low or the customer asks for a person.
- Limits. Meta's pages do not list them beyond saying complex or sensitive requests need a handoff.
What an agent can usefully do
- Answer from your documents: hours, prices, delivery areas, return rules. It is only as right as those documents.
- Check an order or booking through a lookup in your system.
- Take bookings: offer free slots, hold one, confirm it. Read how to prevent double booking first.
- Capture leads and pass them to a person.
- Hand the chat to a person, with history, when the customer asks or the agent is unsure.
Refunds and order changes are a different class of action. See our guide to AI customer service agents.
Meta's agent or a custom agent
| Meta Business Agent | Custom agent | |
|---|---|---|
| Setup | Guided setup in the app | Built to your scope |
| Your systems | Business info and catalogue in the app, APIs on the Platform | Any system with an API |
| Control | Meta's four controls | Prompts, code, limits, approvals |
| First version | Set up by you in the app | A development project |
| AI charges | One token-based Meta charge | Separate model cost plus Meta |
Pick Meta's agent when your answers live in documents and a catalogue. Pick custom when the agent must act in your systems, or needs exact rules, such as approval before a refund.
Rules every WhatsApp agent must follow
The 24-hour window. When a customer messages or calls you, a 24-hour timer starts, and each new message resets it. While it is open you can send ordinary messages, which Meta calls service messages. After it closes, you can only send pre-approved template messages.
Templates. Wording you submit to Meta beforehand, as authentication, marketing or utility. Review can take up to 24 hours. See why WhatsApp templates get rejected.
Charges. Meta's pricing page says that from 1 October 2026 Meta charges per message for service messages, free since November 2024. The rate in each market equals the utility and authentication rate. Template messages are charged when delivered, by category and recipient country. From 1 August 2026, Meta Business Agent messages are charged per token. Meta's main pricing page still called in-window replies free on 9 October 2026, so many guides are out of date. Rates are in our WhatsApp Business API pricing in India guide.
Opt-in. Meta's Business Policy says you may only contact people who gave you their number or username and opted in to messages from you. A reminder weeks later needs opt-in on record.
Messaging limits. Per Meta's messaging limits page, limits cap the unique people you can message outside a service window in a moving 24 hours, per business portfolio. A new portfolio starts at 250. Verifying the business is one way to reach 2,000.
A way to reach a person. The policy allows automation in the 24-hour window but requires prompt, clear, direct escalation: an in-chat transfer, phone number, email, web support, store visit or support form.
AI Providers rule. Meta's AI Providers page says companies whose product is a general-purpose AI assistant may only offer it on the Platform where Meta is legally required to allow it, under terms effective 15 January 2026. A shop using AI for its own orders and bookings does not sell an assistant, in our reading.
Commerce policy. The Business Policy bars using WhatsApp for goods such as firearms, alcohol, tobacco, drugs, medical and healthcare products, live animals, gambling, adult products, dating services, multi-level marketing and payday loans, whatever licences you hold.
We design agents around these rules: scoped to your orders and bookings, a stored last-message time, opt-in recorded per message type, and a person able to take over at any point. Want one built? Tell us about your project.
