WhatsApp Chatbot Using n8n for Multi-Outlet Restaurants
The Project
A renowned multi-outlet restaurant chain approached us with a vision to strengthen customer engagement and loyalty using a personalized, automation-driven rewards experience. The goal was to build a WhatsApp chatbot that could manage royalty rewards, cashback, and feedback collection in real-time through a simple QR-based flow across all their physical locations.

What Our Client Says?
"InfyOm delivered a seamless WhatsApp chatbot using n8n that transformed our loyalty and feedback process. It’s smart, scalable, and has boosted repeat visits and reviews across all our outlets. Great experience!"
The Challenge
FragmentedLoyalty Tracking
The restaurant chain lacked a centralized way to track returning customers and reward them across multiple outlets.
ManualFeedback Collection
Gathering customer feedback and Google reviews was entirely manual, leading to inconsistent review generation and delayed responses.
Receipt-BasedCashback
The system needed to verify spending through receipt uploads via WhatsApp and map that data to loyalty points accurately.
Multi-OutletQR Integration
Each outlet needed a unified but outlet-specific experience via the same chatbot with easy QR code onboarding.
The Solution
Custom WhatsApp ChatbotUsing n8n
We built a fully automated WhatsApp chatbot using n8n workflows and the WhatsApp Cloud API to register users, handle cashback logic, and track their loyalty progress in real-time.
QR-Based Onboarding atOutlets
Unique QR codes placed at each outlet seamlessly initiated a WhatsApp conversation and identified the outlet automatically.
Receipt Upload &Reward Tracking
The chatbot collected receipt images, extracted purchase amounts, updated Google Sheets for progress tracking, and returned dynamic updates to the user.
AutomatedReview Collection
After reward updates, the bot asked for ratings, collected internal feedback, and encouraged customers to leave public reviews on Google.
Results
25,000+ Customer Handled
3x more Google Reviews
40% Growth in Repeat Visits
Key Features
QR-Based WhatsApp Entry Point
Each restaurant outlet is equipped with a unique QR code that customers can scan to instantly start a WhatsApp conversation. This eliminates any manual onboarding and ensures a smooth, one-tap entry into the loyalty program, personalized by outlet location.
Smart Receipt Upload Workflow
Customers can effortlessly upload a photo of their purchase receipt directly in the WhatsApp chat. The chatbot then processes the receipt data, verifies the amount, and automatically updates the user’s progress toward their cashback and royalty milestones - all within seconds.
Google Review Collection
As a final step, users are encouraged to leave a public review via a pre-filled Google Business review link. This flow dramatically boosts online reputation by turning satisfied customers into brand advocates.
