What is a WhatsApp chatbot?
A WhatsApp chatbot is an automated conversational agent that interacts with customers on WhatsApp. It can answer questions, qualify leads, book appointments, process orders and provide 24/7 customer support — all without human intervention.

Building it, step by step
- 01
Define the chatbot's purpose
Decide what it will handle: customer support, lead generation, appointment booking, order management, or a combination.
- 02
Map out conversation flows
Sketch the paths the chatbot will follow — greeting messages, menu options, response branches and fallback handling.
- 03
Use the visual builder
The drag-and-drop builder lets you create flows visually. Add message nodes, button options, conditional logic and AI responses without writing code.
- 04
Configure AI responses
Enable AI-powered responses for open-ended queries. The AI understands context and answers from your knowledge base.
- 05
Set up lead qualification
Add qualification questions to the flow. Based on responses, assign lead scores and route high-intent leads to sales.
- 06
Test and deploy
Test thoroughly before going live: send test messages, verify every conversation path, and check the human handoff.
- 07
Monitor and optimise
Track response accuracy, resolution rate and customer satisfaction, and keep tuning the flows against the data.
Best practices
- Keep messages short and conversational
- Use buttons and quick replies for easy navigation
- Always offer a way to reach a human agent
- Personalise responses with the customer's name
