DOKU Payment Integration

Payment gateway integration with callbacks, status synchronization, and error handling.

Concept illustration, not a product screenshot or an internal architecture diagram.

The challenge

Payment status must stay synchronized across services as callbacks arrive, failures occur, or transactions need to be checked again.

Outcome

Improved payment flow stability and traceability.

My contributions

  • Integrated payment initiation and status checking through DOKU.
  • Developed callback handling and transaction status synchronization.
  • Implemented validation, logging, error handling, and edge-case testing with QA.
