How to Build a WhatsApp Chatbot Without Coding, Step by Step

To build a WhatsApp chatbot without coding, connect your number to the WhatsApp Business API through a no-code platform, create a flow, choose what starts it, connect steps on a canvas, then publish it and test it on your own phone. You don’t write any code, and a simple menu bot can be live in an afternoon.

This guide walks through each step in Automate AI, with a worked example for a small café, how to hand a chat to a person, and the mistakes that catch first-time builders. New to chatbots? Start with what a WhatsApp chatbot is and how it works.

Before you start: what you need

• A number on the WhatsApp Business API. The free Business app only has greeting and away messages and quick replies. Not connected yet? See how to set up the API.
• A plan with the Chatbot Flow Builder. In Automate AI that’s Series 2, 3 and 4. See pricing.
• One job for the bot. Share a price list, book a table or answer the top questions. Add more later.
• Your content. Have your menu or price list, opening hours and most common answers ready.

Step 1: Create a flow

1. Open Automation › Flows and click Create Flow.
2. Give it a name, such as “Café menu”, and a description if you like.
3. Click Continue to Builder. The canvas opens with a Start step, ready to build on.

On the left are two tabs, Messages and Actions. Drag a step onto the canvas to add it.

Step 2: Choose what starts the bot

Click Settings in the builder and pick a Trigger Type:

Keywords ignore capitals, and they match the whole message or a whole word in it. So menu fires on “Can I see the menu?” but not on “menus”. Add the variations you expect, such as menu, menus, price, prices.

A keyword with a space, such as book table, only fires when the message is exactly that, so single words usually work better.

Step 3: Add and connect steps

A flow is a set of steps joined by lines. Drag in a step, fill it in, and connect it to the next one.

Advanced steps can collect photos and files (Collect Media), check answers with AI (AI Validation) and send conversion events to Meta (Conversion Event). You won’t need them for a first bot.

Step 4: Or let Generate with AI draft it

In the builder, click Generate with AI and describe the bot in plain words. For example: “Greet the customer, ask for their email, save it to their contact, then thank them.” The AI builds the flow from the same steps, and you can review and edit everything on the canvas before saving.

Treat it as a first draft. Check the wording, the groups it uses and every branch. Nothing goes live until you publish it.

Step 5: Publish, then test on your phone

Click Save to keep your work and Publish to switch the flow on. A saved flow stays Inactive and won’t reply to anyone.

Only active flows run, so here’s a safe way to test:

1. In Settings, use a private keyword that customers won’t type, such as cafetest42.
2. Publish, then send that keyword from a phone that isn’t your business number.
3. Tap every button and list option, and check each branch ends properly.
4. Fix anything odd, then swap in your real keywords and save.

To switch a flow off later, set its Status to Inactive in Settings.

Worked example: a small café menu

Here’s a small bot for a sample business, Example Café. It shares the menu, takes table requests and reaches a person.

When a branch ends, the customer can still tap another option on the same menu, so you don’t need to send it again.

Hand over to a person

WhatsApp’s Business Messaging Policy says automation must come with “prompt, clear, and direct escalation paths”. It lists in-chat transfer to a person, a phone number, email, web support, store visits and support forms as options. For most businesses, in-chat is the simplest:

1. Put a Talk to a person button in your first message.
2. In that branch, tell the customer what happens next.
3. Alert your team with Send Email, and use Add to Group if you want a list of people waiting.
4. Your team replies from the shared inbox.
5. While someone is helping the customer, open the chat, tap ⋮ and choose Turn chatbot off. Flows, welcome messages and keyword replies stop for that chat only, so the bot won’t restart when the customer says “hi”.
6. Choose Turn chatbot on when you’ve finished.

AI replies have their own switch. If you use the AI Assistant, stop keywords can switch it off so a person can take over.

Common mistakes to avoid

• Forgetting to publish. A saved flow doesn’t reply to anyone.
• Building everything at once. Launch one job, watch where people stop, then add more.
• Long labels. WhatsApp limits reply buttons to 20 characters and list row titles to 24.
• Expecting the bot to message first. Text, button and list steps only reach someone whose 24-hour window is open. To write first, send an approved template to opted-in contacts.
• Putting Update Contact after a button. It waits for the next message, so a tap just before it isn’t saved. Use it after a question people answer by typing, and record tapped choices with Add to Group.
• Saving a reply to Phone Number. That’s the number you reach them on. Put a second number in Notes.
• Asking people to type CANCEL, QUIT or END. In Automate AI those words, sent on their own, opt the contact out, just like STOP. Use a button for those choices.
• Using one keyword in two flows. Keep each keyword in one flow, so you know which one will answer.
• Asking for sensitive details. Never ask for full card, account or ID numbers in a chat.
