What Is the Flow Builder?
The WhatsSMS Flow Builder is a visual, drag-and-drop tool that lets you create complex messaging automation workflows without writing a single line of code. Think of it as a flowchart that comes to life — each node represents an action, condition, or message that executes automatically.
Whether you want to build a customer support flow, an appointment booking sequence, or a lead qualification process, the Flow Builder makes it intuitive and fast.
Getting Started
Access the Flow Builder
Log into your WhatsSMS dashboard and navigate to Tools, then Flows. Click Create New Flow to open the visual builder.
Understanding Flow Components
Flows consist of several component types:
- Trigger nodes define what starts the flow, such as an incoming message or a keyword match
- Message nodes send SMS or WhatsApp messages to the contact
- Condition nodes branch the flow based on rules like message content, time of day, or contact properties
- Action nodes perform tasks like adding to a group, updating contact info, or triggering webhooks
- Delay nodes add time gaps between steps
Building Your First Flow
Start with a simple welcome flow. Add a trigger node that activates when a new contact sends their first message. Connect it to a message node that sends a welcome greeting. Add a condition node to check if they respond, and branch accordingly.
Advanced Flow Patterns
Lead Qualification Flow
Create a multi-step flow that asks qualifying questions. Based on responses, categorize leads as hot, warm, or cold, and route them to appropriate follow-up sequences.
Appointment Booking Flow
Build a conversational flow that checks available time slots, confirms bookings, and sends reminder messages before appointments.
Customer Support Triage
Design a flow that categorizes incoming support requests by topic, provides instant answers for common questions via AI, and escalates complex issues to human agents.
Best Practices
- Start with simple flows and add complexity gradually
- Test every branch of your flow before activating
- Use message templates within flows for consistency
- Add delay nodes to avoid overwhelming contacts with rapid-fire messages
- Monitor flow performance through the activity logger
- Keep flows focused on a single goal or process
Combining Flows with AI
For even more powerful automation, connect your flows with AI plugins. Use AI nodes within flows to generate dynamic responses, analyze message intent, or make intelligent routing decisions.
This combination of visual automation and AI intelligence lets you build sophisticated messaging experiences that feel personal and responsive.
