Payment & Donation API — Cielo & Stripe

A backend platform developed for online donation and payment processing, integrating external payment gateways including Cielo and Stripe.

The system provides REST APIs for creating and managing transactions, processing different payment methods and tracking payment status. The architecture separates payment logic from the application layer and handles communication with external financial APIs.

The project also includes transaction persistence, payment status management, API response handling and a Docker-based deployment environment.
