PAST THE BUILT-IN SETTINGS
Auto reply bots, APIs and options beyond the WhatsApp Business app
The built-in away and greeting messages send fixed text. Everything people search for next, a free auto reply bot, an auto reply API, buttons and options, replies that differ by question, needs the WhatsApp Business Platform instead of the app's settings screen.
The short version
- The app sends one message to everyone. The Platform lets software decide what to send.
- Buttons and list options are Platform features, and outside the 24-hour window they need an approved template.
- Meta AI inside WhatsApp is a WhatsApp feature, not your business's automatic reply. They are different things with the same name.
- There is no auto reply in the standard WhatsApp app. The route is the free Business app, not a third-party add-on.
What the app does, and what the Platform adds
| Capability | WhatsApp Business app | WhatsApp Business Platform |
|---|---|---|
| Fixed greeting and away text | Yes | Yes |
| Schedule and recipient filters | Yes | Yes, and finer |
| A reply that depends on what was asked | No | Yes, this is the point of it |
| Reply buttons and list options | No | Yes |
| Read live calendar availability | No | Yes, through the software you connect |
| Hand over to a named person with context | No, you scroll the chat | Yes |
| Several staff answering the same number | Limited to linked devices | Yes, through a shared inbox |
| Message someone after the 24-hour window | No | Yes, with an approved template |
| Appointment reminders | No | Yes, with an approved template |
Auto reply with options: how buttons actually work
On the Platform, a business can send interactive messages: reply buttons for a small set of choices, and list messages for a longer menu. That is what auto reply with options means in practice, and it is genuinely useful for narrow decisions such as confirming or moving an appointment.
Two rules shape when you can use them. Inside the 24-hour customer service window, which opens when the customer messages you, you can send interactive messages freely. Outside it you need a message template that Meta approved in advance, and Meta decides the category.
Worth saying plainly: buttons are still a menu. They are excellent for confirm or reschedule, and poor for how much would a colour and cut cost on Thursday. The strongest setup uses both, reading the sentence first and offering buttons only where the choice really is small.
Is there a free WhatsApp auto reply bot?
Free means two different things here. Free-as-in-the-app gets you fixed text, already covered. Free-as-in-a-plan means a product on the Platform that has a tier you can stay on.
Meta does not charge for API access itself; it charges by message category, and a reply inside the 24-hour customer service window is not charged under its current published rules. That is why a free tier is possible for a front desk that mostly answers rather than broadcasts.
Elily's Free plan is 150 AI replies a month, with no expiry and no cap on the bookings those replies produce. Enough to find out whether your customers actually use it.
The auto reply API, in plain terms
When people search for a WhatsApp auto reply API they usually want Meta's Cloud API. You register an HTTPS webhook, Meta delivers incoming messages to it, and your code posts replies back.
That gives you the ability to reply automatically. It does not give you anything to say. The work after the API is understanding the question, holding conversation state, reading a calendar, deciding when to fetch a human, and getting templates approved for anything sent outside the customer service window.
If you want to build it, the DIY guide walks through what each route really involves. If you want it working this week, that is what a product on the Platform is for.
How to stop the AI auto reply on WhatsApp Business
Two very different things get called AI auto reply, and the fix depends on which one you have.
The first is Meta AI, the assistant Meta has added inside WhatsApp itself. It is a WhatsApp feature rather than something you installed, and what you can turn off varies by app version and by country. You can stop a conversation with it the way you would any chat; beyond that, WhatsApp's own Help Centre is the only reliable guide to what your version allows, because this changes.
The second is an AI that replies as your business, which is software you or a provider connected to your number. That one has an off switch in its own dashboard, and if it does not, that is a good reason not to use it. Ask any vendor to show you how to pause automatic replies before you sign anything.
Auto reply without a Business account
The standard WhatsApp app has no auto reply feature. There is no hidden setting, and there is no supported way to add one.
The intended route is the free WhatsApp Business app on the same number. WhatsApp publishes a migration path: back up your chats first, then follow the steps in its Help Centre. You keep your number and your history, and your personal contacts see very little difference.
Third-party Android apps do exist that fake auto replies through accessibility permissions. They sit outside WhatsApp's terms, they read your notifications to work, and the number they are attached to is the one your customers have saved. It is a poor trade for a feature the official free app already has.
Signs you have outgrown the built-in tools
- Customers reply to your away message with the same question anyway.
- You answer the same three price questions every morning before you have had coffee.
- Bookings are being lost in the gap between the reply and someone getting to the phone.
- More than one person needs to answer the same number and they trip over each other.
- You want to send an appointment reminder, which the app cannot do at all.
- You catch yourself apologising for the automatic message when you finally reply.
The version that answers the question
Elily runs on your own number through the official Platform. She answers from your services, prices and hours, books into Google Calendar, and hands over to your team when a person should decide.
QUESTIONS BEFORE YOU START
Common questions
Is there a free auto reply bot for WhatsApp Business?
Yes, in the sense of a product with a free tier on the WhatsApp Business Platform. Elily's Free plan includes 150 AI replies a month with no expiry and no booking cap. The free WhatsApp Business app is not a bot; it sends fixed text.
Can I send an auto reply with buttons or options?
On the WhatsApp Business Platform, yes: reply buttons and list messages are both supported. Inside the 24-hour customer service window you can send them freely; outside it you need a message template Meta approved in advance. The app's built-in auto replies cannot send buttons.
How do I stop the AI auto reply on WhatsApp Business?
Check which one it is. Meta AI is a WhatsApp feature and what you can disable depends on your app version and country, so WhatsApp's Help Centre is the source. An AI that replies as your business is software connected to your number and is switched off in that software's own settings.
Can I set an auto reply without a WhatsApp Business account?
No. The standard WhatsApp app has no auto reply. Move to the free WhatsApp Business app on the same number, backing up your chats first. Third-party apps that fake it through accessibility permissions sit outside WhatsApp's terms and put your number at risk.
Do I need the API just to send an away message?
No. If fixed text on a schedule is all you need, the free app does it well and costs nothing. The Platform is for when the reply has to depend on what the customer actually asked, or has to check a calendar, or has to reach someone after the 24-hour window.
