I’ve decided to shake up my routine and learn something completely new: turning the thrill of each Amazon FBA sale into an audible “cha‑ching!” in my browser. The real experiment isn’t the sound itself—it’s proving that, with today’s digital tools, anyone can turn a half‑serious idea into reality. Services like AWS give me cloud superpowers for pennies, and ChatGPT helps me bridge knowledge gaps on the fly, so I can focus on curiosity instead of credentials. My plan is simply to explore, tinker, and learn in public: celebrating each tiny breakthrough, sharing every misstep, and showing that you don’t need to be a full‑time developer to build something that delights you. Here’s to trying, learning, and letting technology be an open playground for all of us.
Cha‑Ching by Dominik
Real‑time alerts for every new Amazon FBA sale – right in your browser.
Cha‑Ching plays the classic cash‑register sound the instant Amazon records an order. No constant refreshing of Seller Central, no policy risks: we rely exclusively on the official Amazon Selling Partner API (SP‑API).
What does Cha‑Ching do?
| Feature | Benefit |
|---|---|
| Instant notifications (Web Push) | Hear about every sale within seconds—perfect for product launches and ad campaigns. |
| Customizable sound | Use the classic “cha‑ching” or upload your own audio file. |
| Multi‑marketplace support | Monitor EU markets (DE, FR, IT, ES, NL, SE, PL) and the US at the same time. |
| 100 % API compliant | No automated logins, no scraping—only officially authorized SP‑API events. |
How it works
- Connect your Amazon account
Complete a one‑time Login with Amazon OAuth flow to grant Cha‑Ching access. - Amazon emits ORDER_CHANGE events
New orders travel through Amazon EventBridge to our cloud service. - We push the signal to your browser
An encrypted Web Push message triggers the browser extension—and the cash register rings!
Security & Privacy
- OAuth 2.0 with LWA: We never store your Seller Central login data.
- Minimal data storage: We process only order metadata (order ID, marketplace, timestamp)—no customer PII.
