Let’s Go Pizza, loyalty verified by the payment terminal

One QR code, WhatsApp, and no app to install.

Project at a glance

The need: Help customers find a pizza vending machine and return, without installing an app.
My contribution: Reworked the Google presence and built WhatsApp loyalty linked to the terminal’s sales data.

What was built

Google presence
WhatsApp journey
Purchase verification
Loyalty tracking

Documented state: program and connections active; a real-sale acceptance test is still required before displaying the QR code. The Wallet visual is a mock-up.

Nature: Local presence and WhatsApp loyalty
Period: Since April 2026
Client: Let's Go PizzaAutomatic pizza vending machine, Bayonne, open 24/7

The problem

An automatic pizza vending machine, open day and night in Bayonne, with an almost empty Google listing: no description, no Q&A, no posts. And no link with customers once the pizza has left the machine. The constraints were clear: no website, no app to install.

The approach

Two pillars, nothing else: being found, with the Google listing, and bringing customers back, with a WhatsApp journey. Proof of purchase comes from the payment terminal itself, neither a photo nor a claim: one sale earns one loyalty credit, never two. And the AI hands nothing out: it converses, but reward codes are issued by the program, not by the model.

The solution

Google listing rebuilt: description, service areas, menu, posts, replies to reviews.
A QR code on the machine opens a WhatsApp conversation (official API); the message "NIGHT" triggers the purchase check.
Loyalty: every ten verified purchases, the 11th Margherita pizza is free.
After the meal, an optional invitation to rate. The same Google review link is offered whatever the rating; a low rating simply alerts the manager, privately.
Consent and opt-out: GDPR notice in the first message, stop at any time with "STOP".
A program hosted on Cloudflare Workers, conversations in four languages, and a weekly recap for the manager.

Where commissioning stands

The program is live, and the production WhatsApp number and the link to the terminal’s sales data are active. The full journey — pizza paid, QR code scanned, a single credit — still has to be proven on a real sale before the QR code goes up in public. The Apple Wallet and Google Wallet card shown below is a mock-up, not an activated feature. No result (Google rating, footfall, loyalty) is claimed.
