A WhatsApp chatbot can answer your most common customer questions 24x7, qualify leads while you sleep, and hand off to a human only when it actually matters — and you can build one without writing a single line of code. In this step-by-step tutorial, you'll create a working chatbot using GlobVoice's visual flow builder, complete with keyword triggers, branch logic, AI-powered replies, and a clean handoff to your support team. Set aside about 30 minutes; by the end you'll have a bot live on your WhatsApp Business number.
What you need before you start
To build and launch a WhatsApp chatbot you need a WhatsApp Business API account (not the regular WhatsApp Business app — the API is what allows automation). If you're unsure of the difference, read our explainer on the WhatsApp Business API vs the app first. You'll also need a GlobVoice account, a verified sender number, and a rough idea of the top 5–10 questions your customers ask. That's it — no server, no Python, no webhooks to wire up by hand.
The build: 7 steps to a live chatbot
- Connect your WhatsApp number and open the flow builder. In GlobVoice, go to Channels → WhatsApp and link your verified sender. Then open Chatbot → Flows and create a new flow. You'll see a blank canvas where each block is a step in the conversation — drag, drop and connect them visually, exactly like drawing a flowchart.
- Set the trigger that starts the bot. Choose what kicks off the conversation. The most common triggers are a keyword (the customer texts "hi", "menu" or "price"), the first message from a new contact, or a click on a WhatsApp click-to-chat link you've placed in an ad or on your website. Add a welcome message block right after the trigger: a friendly greeting plus a short menu of options the bot can help with.
- Add a menu with quick-reply buttons. Drop in a buttons block and give the customer 3–4 clear choices — for example "🛍️ Products", "💰 Pricing", "📦 Track my order", "👩💻 Talk to a human". Buttons dramatically reduce confusion because the customer taps instead of typing free text, and each button becomes a labelled branch you connect to the next step.
- Build branch logic with conditions. Use condition blocks to send each customer down the right path. Branch on which button they tapped, on saved contact attributes (is this a returning customer? what city are they in?), or on what they typed. For example: if the order-status branch is taken, ask for the order ID, then show the matching status. This if/then/else logic is what turns a static auto-reply into a real assistant — and you build it all by connecting blocks, no code.
- Add AI replies for open-ended questions. For questions you can't anticipate, drop in an AI block. GlobVoice uses Groq-powered language models that answer in the customer's own language — Hindi, Bengali, Assamese, Tamil and more — grounded in a knowledge base you provide (paste your FAQs, policies or product details). The AI handles the long tail of "do you ship to Guwahati?" or "what's your return policy?" naturally, so you don't have to script every possible question. See how this works across regional languages in our guide to AI chatbots in Hindi, Bengali and Assamese.
- Capture data and trigger actions. Add blocks that save what the customer tells you — name, email, product interest — to their contact profile or to a campaign list. You can also fire actions here: tag the contact as a hot lead, add them to a follow-up sequence, or send order details to your team. This is how a chatbot becomes a lead-generation engine, not just a Q&A toy.
- Set up human handoff. No bot should trap a customer. Add a handoff block on your "Talk to a human" branch and as a fallback when the AI's confidence is low or the customer types something like "agent" or "complaint". The conversation drops into your shared team inbox, the bot pauses, and a live agent takes over seamlessly — with the full chat history visible. When the agent is done, the bot can resume.
Test before you go live
Use the builder's preview/simulator to walk every branch as if you were the customer. Tap each button, type the unexpected things real people type ("hii", "kitna", "price kya hai"), and confirm the AI answers correctly and the handoff fires. Pay special attention to dead ends — every path should either resolve the query or route to a human. Fix any branch that loops or leaves the customer hanging.
Publish and connect it to the real world
Once you're happy, hit Publish. Your bot is now live on your WhatsApp number. The fastest way to drive people to it:
- Generate a click-to-chat link with a pre-filled message using our free WhatsApp link generator, and put it in your Instagram bio, email signature and ads.
- Turn that link into a scannable QR code for your storefront, packaging, business cards and print ads — customers scan and land straight in the bot.
Tips to make your chatbot actually convert
- Keep the welcome short. One line of greeting plus the menu. Walls of text get ignored.
- Lead with buttons, fall back to AI. Buttons for the predictable 80%, AI for the unpredictable 20%.
- Always offer the human escape hatch. Visible "talk to a human" option at every stage builds trust.
- Respect the 24-hour window. After 24 hours of customer silence, you can only re-engage with an approved template message — plan your follow-ups accordingly.
- Mind your sending reputation. A good bot reduces spam complaints, but if you're also running broadcasts, follow the rules in our guide to sending bulk WhatsApp without getting banned.
Why no-code beats hiring a developer
A custom-coded WhatsApp bot means paying a developer, hosting a server, and re-deploying every time you want to change a single reply. With a visual builder, your marketing or support team edits the flow themselves in minutes — no deployment, no downtime. If you want the bigger picture on WhatsApp as a marketing channel, our WhatsApp marketing guide for 2026 covers strategy, templates and automation end-to-end. And if you're comparing chatbot platforms, our GlobVoice vs Interakt comparison shows how the flow builder and AI stack up.
