What is a WhatsApp Flow?

A WhatsApp Flow is a structured, interactive experience you can send to customers inside a WhatsApp chat. Flows are defined as JSON and rendered natively in WhatsApp, letting users fill forms, pick options, upload files, book appointments, and more without leaving the chat.

How do I use the Flow JSON generated by this tool?

Copy the JSON from the Export panel, open the Meta WhatsApp Flow Builder in your Business Manager, create a new Flow, switch to the JSON tab, and paste it in. Save and publish the Flow, then reference its Flow ID from a WhatsApp template or interactive message.

Which WhatsApp Flow components are supported?

This builder supports the most common WhatsApp Flow components including TextHeading, TextSubheading, TextBody, TextCaption, TextInput, TextArea, Dropdown, RadioButtonsGroup, CheckboxGroup, DatePicker, OptIn, EmbeddedLink, Image, and Footer. You can add multiple screens and configure navigation between them.

Is this WhatsApp Flow Builder really free?

Yes. This tool is 100% free with no signup required. Everything runs in your browser - your Flow JSON is never sent to a server.

How to Build a WhatsApp Flow Visually

A WhatsApp Flow is a native, interactive experience rendered inside WhatsApp chats. Instead of bouncing customers to a web form, you can show them a multi-step form, a date picker, a product chooser, or a survey right in the conversation. Flows are described by a JSON document that follows Meta's Flow JSON specification, and this free builder gives you a drag-and-drop editor so you never have to hand-write that JSON from scratch.

Add Screens

Create one screen per step in your flow. Set the title, ID, and mark the final screen as terminal.

Drag Components

Drag headings, inputs, dropdowns, date pickers, images, and footers onto each screen and configure their properties inline.

Export Flow JSON

Copy the generated JSON and paste it into the Meta Flow Builder in your WhatsApp Business Manager to publish the Flow.

Supported Flow Components

This builder supports the most common WhatsApp Flow components:

Text - TextHeading, TextSubheading, TextBody, TextCaption for static copy
Inputs - TextInput, TextArea for free-form text entry
Choices - Dropdown, RadioButtonsGroup, CheckboxGroup for selections
DatePicker - Collect dates for bookings, reminders, and appointments
OptIn - Terms and consent checkboxes
EmbeddedLink - Links that open external URLs or navigate to other screens
Image - Product photos, diagrams, banners
Footer - Primary action button that submits the screen and moves forward

Why Use WhatsApp Flows Instead of a Web Form?

Higher completion - Users never leave WhatsApp, so drop-off is dramatically lower than redirecting to a browser
Native feel - Flows render with WhatsApp's own UI, which users already trust
Pre-filled data - Phone numbers and other context are already known
Works on every device - Identical experience on Android, iOS, and WhatsApp Web

Go Live with Whautomate

Designing the JSON is step one. To actually send a Flow to customers you still need an approved WhatsApp Business API account, a message template that references the Flow ID, and a way to handle the responses. Whautomate gives you all three: an approved WhatsApp Business API setup, a no-code template builder, a team inbox for responses, and automation workflows that trigger when a Flow is completed. Before you go live, make sure your number is eligible for the WhatsApp blue tick and that you have completed Meta Business Verification - both are prerequisites for publishing interactive Flows at scale.

Pair Your Flow with the Right Message

A Flow only triggers when a customer taps a button in a WhatsApp message. Use our free WhatsApp Button Generator to add a chat entry point to your website, generate a WhatsApp QR code for offline campaigns, or create a click-to-chat link for ads and emails.
