How to make a WhatsApp chatbot (no-code, in under an hour)
A WhatsApp chatbot answers customer questions, qualifies leads, books appointments and processes orders 24/7 — without your team touching the keyboard. You don't need to be a developer. Modern Business Solution Providers ship visual flow builders that connect buttons, conditions and AI replies in a drag-and-drop canvas.
This tutorial covers the full path: WhatsApp API access, flow design, AI integration, testing and launch.
- 1
Get a WhatsApp Business API number
Sign up with a Meta-approved BSP like LandinChat. You'll need a Facebook Business Manager, a verified business and a phone number not on personal WhatsApp. Approval takes a few hours to a couple of days.
- 2
Map the top 10 user questions
Pull 30 days of inbox chats and group by intent — 'pricing', 'shipping status', 'book a demo', etc. The top 10 intents usually cover 80% of incoming volume. Write a one-line answer for each.
- 3
Build the flow visually
Open the chatbot builder, drag a 'Trigger' node (keyword or 'first message'), add 'Send message' nodes with quick-reply buttons, and branch to follow-ups. Use 'Collect input' nodes for name/email/order ID.
- 4
Plug in AI for unknown questions
Add an 'AI fallback' node that calls GPT-4o or Gemini with your business knowledge base (FAQs, return policy, pricing). The model answers questions outside the scripted flow in your brand voice.
- 5
Test on a sandbox number
Most BSPs offer a test number. Send every keyword, every button, every edge case (empty input, typos). Fix dead-end branches before going live.
- 6
Go live and monitor
Switch the bot to your production number. Watch the inbox for the first 48 hours — escalate to a human anytime confidence is low.
Pro tips
- → Always offer a 'Talk to a human' button — never trap users in a loop.
- → Limit each message to 3 buttons; WhatsApp shows a list for more.
- → Keep replies under 1024 characters or split them — long blocks hurt readability.
Frequently asked questions
Do I need to code?
No. Visual builders cover 95% of use cases. APIs are only needed for deep CRM logic.

How much does a WhatsApp chatbot cost?
Platform subscriptions start around ₹2,000–₹5,000/mo plus Meta's per-conversation fees ($0.005–$0.108).
