How do you answer WhatsApp automatically?
There are three ways, and each one solves a different thing. The WhatsApp Business app sends ready-made replies for free, the menu chatbot walks the customer through numbered options, and the AI agent reads the written question and really answers on your number.
Free WhatsApp Business features
In the app's Tools tab you turn on the greeting message, which goes to people writing for the first time or after 14 days without a conversation, and the away message, which goes out at the hours you choose. Quick replies are shortcuts to texts you repeat, but you are still the one sending. Everything is fixed text, and the phone needs an internet connection for the messages to go out.
Menu chatbot
It is the robot of "type 1 for price, type 2 for hours". It follows a path built beforehand and handles predictable questions. When the customer writes something outside the options, it does not understand and repeats the menu.
AI agent on your number
An artificial intelligence program reads the message the way the customer wrote it and answers with your business's information. At CertuAI it also books appointments, goes back to people who stopped replying and calls you when the topic needs a person.
Meta is also testing an AI inside the app itself, the Meta Business Agent, for now available only to selected businesses in some countries, according to the WhatsApp Help Center. When it is turned on, the greeting and away messages are turned off. The step-by-step for the free features is in how to automate customer service on WhatsApp.
How does automatic customer service work?
With an AI agent, the message arrives, the AI understands it, answers or does the task, and calls a person when needed. Everything happens in seconds, on the same number the customer already knows, and that is how it works at CertuAI.
The message arrives
The customer writes to the usual number, at any hour. The agent is linked to that number by QR code or through Meta's official API, which is the official door Meta opens for companies' systems.
The AI understands and looks for the answer
The agent reads the question using the customer's own words and looks for the answer in the Brain, the knowledge base with your prices, hours and rules.
Answers or does the task
It answers, shows the open slots, books them on the calendar and logs the contact in the dashboard. If the customer goes quiet after the quote, the agent gets back in touch at the right time.
Calls a person when needed
If the question falls outside what it learned, the agent does not make things up: it tells the customer that someone will get back to them and sends you the summary so you can continue in the same conversation.
What does WhatsApp automation do for your business?
It takes over the repetitive work of customer service and gives you your time back. The agent answers right away, books appointments, follows up with people who stopped replying and leaves every contact logged, and you step into the conversation when the topic calls for a person.
Answers right away, at any hour
Price, deadline, hours, address and payment method. The agent answers with your business's information late at night, at lunch and on Sunday, while you are with another customer.
Books and confirms appointments
The agent shows the open slots, books them on the calendar and confirms the day before. The back-and-forth of messages just to find a day that works for both sides is over.
Picks up the stalled quote
Whoever got a proposal and did not reply gets a polite follow-up at the right time. It is sales that were already inside your WhatsApp and nobody had time to go get.
Leaves everything logged in the CRM
Each conversation becomes a contact, a deal and a task on its own. You open the dashboard and see what is open, without depending on anyone's memory.
The same automation answers on Instagram Direct and Messenger, on Start, Pro and Max, and each conversation becomes a contact, a deal and a task in the CRM.

Get startedHow do you automate your business's WhatsApp?
It is three steps and none of them is technical: you teach the business, connect the number you already use and follow along in the CRM. It takes minutes, not weeks, and there is no visit or installation, because everything happens in the browser.
Teach the business to the Brain
Services, prices, hours, rules and what you would rather nobody answer. The Brain is the knowledge base that makes the agent answer like your company, and not like a generic robot.
Connect the number you already use
By QR code or through Meta's official signup. CertuAI is a Tech Provider of the Meta WhatsApp Business Platform, and the number stays yours: the plan gives you the connection slot, not a new number.
Follow along in the CRM and take over whenever you want
Each conversation shows up in the dashboard with a contact, a deal and a task. You step into the same conversation at any time, and the agent hands the topic back to you when it falls outside what it learned.
What changes in your day after you automate?
Who writes the first reply changes. The tasks below leave your hands and start happening on their own, with you following along in the dashboard.
| Task of the day | Done by hand | With the CertuAI agent |
|---|---|---|
| First reply to the customer | Depends on someone being free | In seconds, at any hour |
| Price, deadline, address, payment | You repeat the same text all day | The agent answers the way you taught it |
| Scheduling and confirmation | Back-and-forth of messages until a time is found | Books, confirms the day before and reschedules on its own |
| Quote sent and no reply | Gets put off and goes cold | Automatic follow-up at the right time |
| Contact record | Notebook, spreadsheet or nothing | Becomes a contact, a deal and a task in the CRM |
| Night, lunch and weekend | The customer waits until Monday | Served right away, without you opening your phone |

Does automation make customer service robotic?
No, because the agent answers from the Brain, your business's knowledge base. It uses your prices, your rules and your way of speaking, so the customer reads an answer from your company and not a generic text.
When the topic calls for a person, the agent holds the conversation, tells the customer that you will get back to them and notifies you right away. You step into the same conversation, without the customer having to repeat anything.
And nothing gets lost along the way: each contact becomes a record in the CRM, with the full history. If you want to see the agent chatting before deciding, the AI agent demos are open and the AI WhatsApp chatbot explains the difference from the menu bot.
Frequently asked questions about WhatsApp automation
Does automating WhatsApp make customer service robotic?
No, because the agent answers from the Brain, which is your business's knowledge base. It talks in Portuguese in your tone, uses your terms and hands back to a person whatever is sensitive.
Do I need to change numbers to automate?
No. You connect the number your customers already know, by QR code or through Meta's official signup. The number stays yours, and the plan gives you the connection slot.
How much does it cost to automate customer service on WhatsApp?
At CertuAI the Start plan costs US$ 75 per month and already includes the agent, the Brain, the CRM and automatic follow-up.
Is there a way to automate WhatsApp for free?
In part. In the WhatsApp Business app, under the Tools tab, the greeting message, the away message and quick replies cost nothing, but they always send the same text and do not answer the customer's question.
Step by step of what WhatsApp Business already does for free
What is the best tool to automate WhatsApp?
There is no single best WhatsApp automation tool for everyone. Compare who answers (a menu or an AI), whether the tool uses Meta's official connection, how much it comes to per month once you add what Meta charges separately, and whether the customer records come bundled in. We compared 10 platforms using the price each company publishes on its own website.
How does automated message sending on WhatsApp work?
Answering people who wrote to you and sending messages to your list are different things. Through the official API, the company can reply with any text for 24 hours after the customer's last message (starting October 1, 2026, Meta charges for those replies after the first 1,000 of the month on each number); outside that window, or to start a conversation, only a message template approved by Meta works, sent to people who agreed to receive it, and the marketing template is always charged. Mass messaging through an unofficial app goes against WhatsApp's terms and can get the number banned.
Can WhatsApp ban you for automation? The rules
Can you automate only part of the customer service?
Yes. You define what the agent answers on its own and what it sends straight to your team. It is common to start with price and hours and expand later.
What happens when the agent does not know the answer?
It does not make things up. The agent holds the conversation, tells the customer that a person will get back to them and notifies you right away, with a summary of what has already been discussed.
Does the automation work together with my team?
Yes. The agent handles the first contact and hands off the conversation with the summary ready for the right person to continue. Start has 5 people, Pro has 10 and Max has 25.
Do I need to know how to code or build flows?
No. There is no "type 1, type 2" flow to build. You teach the business in a conversation, the same way you would explain it to a new employee.
Is there a lock-in contract or setup fee?
There is no lock-in contract and no setup fee. The annual plan comes with about 17% off.
