WhatsApp is where many customers already write to businesses, so a chatbot there is a natural idea. This guide explains, without selling you one, what a WhatsApp chatbot involves in 2026: which version of WhatsApp you need, how Meta charges, the rules you must follow and when another channel serves you better.
A note on where we stand: LinkAIG does not build WhatsApp integrations. We wrote this guide so you can make the call with clear information.
The WhatsApp Business app vs the Business Platform
There are two products, and only one of them can run a real chatbot:
| WhatsApp Business (app) | WhatsApp Business Platform (API) | |
|---|---|---|
| Cost | Free | Charged per template message |
| Automation | Quick replies, greeting and away messages | Full automation through code or a provider |
| Connections | None | CRM, store, helpdesk, your own systems |
| Access | Download the app | Meta’s Cloud API or a Business Solution Provider |
In short: if a bot has to answer on its own or talk to your systems, you need the Business Platform.
What a WhatsApp chatbot can do
- Answer frequent questions about hours, prices, stock or order status.
- Take bookings and send reminders.
- Collect details from a new lead before a person takes over.
- Send notifications customers asked for: confirmations, shipping, payments.
- Hand off to a person when the question needs judgment.
How Meta charges
Since 1 July 2025, Meta charges per delivered template message, not per conversation. The rate depends on two things: the template category and the country of the recipient’s number.
- Marketing: offers, news and promotions. Always charged.
- Utility: updates about something the customer did, like an order or a payment. Free when sent inside an open customer-service window.
- Authentication: one-time codes.
Replies to a customer who wrote to you in the last 24 hours are not charged. Rates change by country, so check Meta’s current price list for the countries you serve. Providers may add their own fees on top.
The rules that apply
- 24-hour window: you can reply freely within 24 hours of the customer’s last message. After that, only approved templates.
- Opt-in: customers must agree to receive your messages.
- Quality rating: blocks and reports lower your rating and can limit how many people you can message.
- No unofficial tools: automating the regular app with unofficial software can get the number banned.
- No general-purpose AI assistants: since 15 January 2026, Meta’s terms bar chatbots whose product is the AI itself. Using AI to serve your own customers is allowed.
Is WhatsApp the right channel for you?
It usually is when your customers already write to you there and the questions repeat. It usually is not when:
- the people you want to help are your own team, who work in email, a CRM or spreadsheets;
- most visitors arrive at your website first;
- you mainly want to send promotions, which are always charged and hurt your rating if people did not ask for them.
In those cases a chatbot on your website, or an assistant inside the tools your team already uses, does the same job with fewer rules and costs.
Before you start
- List the ten questions you answer most. If they repeat, automation pays off.
- Decide who takes over. Every bot needs a clear handoff to a person.
- Count the templates you will need and in which countries, to estimate the monthly cost.
- Test every path before customers do.
Key takeaway
A WhatsApp chatbot works best when customers already write to you there and the questions repeat. It needs the Business Platform, a plan for templates and their cost, and a clear handoff to a person. When the work lives elsewhere, put the assistant where your team and your customers already are.
