Fruit Dollar is an application that allows users to play skill games and earn real money. While there's a lot of legacy code, overall, it's a reliable system, in my opinion.
The demand was to integrate with the payment platform ezzebank, which was quite exciting. This integration enables the platform to accept deposits using PIX, a Brazilian system created by the Brazilian Central Bank for instant payments.
Integrating with ezzebank was seamless, especially because some parts of the integration code were already finished when I joined the project. The part where I spent the most time was setting up the webhook. 🕒 Essentially, when a user initiates a payment on the platform, we generate a QR Code. After the user makes the payment, we receive a webhook notification from ezzebank. All this is secured by authentication via signature and basic auth. The webhook informs us that the payment for user_id 321 is confirmed, so we should update the user's platform credit and refresh the user's screen.
Implementing the webhook functionality was a fascinating challenge. If you'd like to chat with me and discuss the technical details, I'd be more than happy to do so! Telegram
