PayBridge

Payment orchestration backend

Java 21 and Spring Boot payments backend that keeps payment and reversal flows consistent across Stripe and NicePay, with retry safe recording, webhook deduplication, operator review pages.

Shared lifecycle Approvals, refunds, cancellations, and partial reversals

Provider execution paths write into one payment record and one reversal history.

Operator visibility Search, detail, and JSON exports

Authenticated operator pages expose transactions, audit logs, outbox records, and recent webhook activity.

Runtime proof Tests, CI/CD, and AWS demo

GitHub Actions runs automated tests before deploying the Docker Compose stack to one Graviton EC2 host with PostgreSQL on the same instance.

What this service covers

  • One shared payment and reversal lifecycle across Stripe PaymentIntents and NicePay test approvals.
  • Idempotency records and webhook event deduplication help prevent duplicate payment state changes.
  • Audit logs and outbox records make approvals, refunds, cancellations, and webhook acknowledgements easier to trace.
  • Operator pages and JSON APIs support transaction search, audit inspection, outbox review, webhook review, and machine readable exports.
