WhatsApp bots explained: the app, the Business Platform and what each allows
Short answer
A WhatsApp bot is software that replies to WhatsApp messages for a business. The free WhatsApp Business app covers greetings and away messages for a small business. A real bot needs the WhatsApp Business Platform, whose Cloud API is built for developers and charges per template message. Meta’s rules decide what a bot can send: free-form replies inside a 24 hour window, approved templates outside it, and opt-in before any template.
On this page
This guide follows Meta’s and WhatsApp’s own pages, read on 12 Oct 2026. It has not been tested hands-on, so it has no screenshots. Where a page did not say, the text says “Not confirmed from the official documentation on 12 Oct 2026”. The same ideas for Facebook Pages are in the Messenger bot guide.

The WhatsApp Business app. WhatsApp’s page says the app lets you “Greet people the moment they start a conversation and respond to messages even when you’re away”, and helps you “showcase your products and services, set prices and share items with customers”. People search for it as “WhatsApp app business”. It is a good first step for a small shop. The page did not list limits on devices or contacts, and it did not mention quick replies or labels. Check the app for those.
The WhatsApp Business Platform. Meta’s documentation describes the Platform as letting businesses “communicate with customers at scale”, with the Cloud API as its core messaging interface. It lets developers “programmatically send messages (text, rich media, and interactive) and make and receive calls”. To use it, you need a business portfolio, a business phone number that can be real or virtual, and an access token, since requests use OAuth access tokens. A bot lives here. WhatsApp’s Platform page describes using it to “deploy automated conversational flows to mitigate high volume inbound support requests”, routing to a person “only when live agent support is needed”.
What a bot can send
Inside the window. When a person messages you, a 24 hour customer service window opens. Meta’s pricing page says non-template messages “can only be sent within an open customer service window”, and that they are free inside it. If a person messages at hour 2, the window closes at hour 26. A separate 72 hour free entry point applies when a chat starts from a Click to WhatsApp ad or a Facebook Page call-to-action button.
Outside the window. Only template messages can be sent. Meta’s documentation says templates “are also the only type of message that can be sent to WhatsApp users outside of a customer service window”, and that you must get the user’s opt-in before sending them.
Templates. A template is a message with fixed wording and slots for details, written in advance. Meta’s guidelines require each one to be classed as authentication, marketing or utility. Templates are reviewed automatically when created or edited; approved ones get the APPROVED status and can be sent, and rejected ones cannot. The documentation says “Review can take up to 24 hours” for templates marked In-Review. Its example is an order confirmation: “Hi (name)! Your order number is (number). Thank you.” The reasons for rejection sit on a separate Meta page that this guide did not read.
Opt-in and policy in plain terms
WhatsApp’s Business Messaging Policy, last updated 23 September 2026, says a business must have “received opt-in permission from the recipient”. Its best practices suggest separate opt-in by message category and clear instructions for opting out of specific categories. It permits automation: “You may use automation when responding during the 24-hour window”, provided there are “prompt, clear, and direct escalation paths” to a person, such as an in-chat transfer, phone, email or web support. It bars offensive content, such as sexually explicit material, and the organising of criminal activity.
AI providers. Meta’s WhatsApp Business Platform terms, last modified 23 September 2026, include clause 4.7: AI providers “are strictly prohibited from accessing or using the WhatsApp Business Platform, whether directly or indirectly”. The ban applies when the AI technology is the product’s main function, not an incidental feature. Meta’s text says a business may still keep an AI provider as its Solution Provider, but may not let platform data train AI models. A business using AI inside its own customer service bot is in a different position from a company selling a general-purpose chatbot, but read the terms or ask Meta when your case is close to the line. This guide does not interpret them.
What it costs
Meta’s pricing page says that since 1 July 2025 it charges per message and not per conversation. It charges only for template messages, and only when delivered. Rates depend on the template category, volume tier and the recipient’s country calling code. Free inside the window: non-template messages and utility templates. The current rate cards took effect 1 July 2026, and Meta can change prices only on 1 January, 1 April, 1 July or 1 October.
For the Philippines, the page puts the +63 calling code under the Rest of Asia Pacific region. It gives no rate figures in the page text, and rate cards are provided as files per currency. The list did not include pesos, so use the USD rate card or WhatsApp’s pricing site for the actual number. Because of that, no peso figure is quoted here. HighLevel’s platform lists WhatsApp as an add-on at US$10 per month per sub-account, about PHP 628; Meta’s per-message charges are separate. See the GoHighLevel page.
Example flows
These are illustrations, not data from any business.
- Opening-hours bot. A customer asks about hours or location; the bot answers from a short list and offers “talk to a person”.
- Order status. The customer sends an order number; the bot looks it up and replies inside the window.
- Appointment reminder. A utility template tells the customer the time and place. The customer must have opted in.
- Lead capture. The bot asks for name, need and a preferred time, then notifies staff.
Build the person handover first: a “talk to a person” option in every menu, and a named staff member watching the inbox. The AI chatbot guide explains rule-based and AI bots, and the chatbot platform comparison lines up tools.
Builder options
| Route | Good for | Notes |
|---|---|---|
| WhatsApp Business app | A greeting, away message and catalog | No bot |
| A no-code builder | Menus, forms and flows without writing code | Manychat is one example; whether it supports WhatsApp: Not confirmed from the official documentation on 12 Oct 2026, so check its current channel list |
| A CRM platform | Chat plus pipeline and booking | HighLevel lists a WhatsApp add-on |
| Cloud API with a developer | Custom flows and integrations | Needs a business portfolio, number and token |

Searches for “whatsapp bot builder”, “ai whatsapp bot” and “auto reply bot for whatsapp” belong to the middle rows. Compare free-plan limits and who owns your flows before you commit. A builder needs the account owner to connect the business number, so use the business’s own account.
A note for developers
A developer building a bot on the Cloud API makes web requests authenticated with an OAuth access token, so a library in a language such as Python can send them. This guide does not recommend a Python library: Not confirmed from the official documentation on 12 Oct 2026. Be careful with unofficial tools that drive the consumer WhatsApp app; Meta’s documentation read here describes only the Cloud API route for businesses.
Frequently asked questions
What is a WhatsApp bot?
Software that replies to WhatsApp messages for a business, answering common questions, collecting details or passing the chat to a person.
