-
User Successfully Tops Up DDC Wallet via Credit/Debit Card
- User logs in, enters amount and card details, payment is processed, DDC balance increases, confirmation displayed, transaction recorded.
-
Payment Security and Compliance
- Card fields rendered via secure, PCI DSS-compliant IFRAME; raw card data never stored.
-
Handling Failed or Declined Payments
- Clear error messages for failed payments, no funds deducted, failed transactions logged.
-
Payment Method Management
- Users can add, remove, or update payment methods securely; changes are immediate and confirmed.
Testing and Validation
- Use the Developer Console UI to simulate top-up transactions with test cards.
- Ensure all payment flows are executed securely and that sensitive card data is never exposed to the frontend or stored on your servers.
- Validate that the backend correctly processes payments, updates DDC wallet balances, and manages payment method tokens for future transactions.
Deployment
- Provide clear documentation and Docker images to facilitate both local and production deployments.
- Ensure environment variables and configuration steps are well-documented for smooth integration and scaling.
