SaFi Bank Space : 🟢 Epic: Top-up via Debit Card (Paynamics) | Only in App

Requirement: user must be able to top-up his/her master SaFI Account from the Debit card from within the SaFI Mobile App.

Execution Steps (happy path):

1. User selects debit card top-up
2. User fills up transaction details (amount) and submits the transaction
3. Validate transaction details (min. amount, max. amount)
4. Get customer details
5. Run fraud check
6. Save transaction
7. Send request to paynamics whether card supports 3D Secure technology (ENROLMENT CHECKING)
   1. if 3D Secure is supported
      1. Create PAYER AUTHENTICATION request and send it to Paynamics
      2. Process response and redirect UI to 3D Secure page
   2. if 3D Secure is not supported, go directly to TRANSACTION SUBMISSION
8. TRANSACTION SUBMISSION invoked directly by flow or by callback in case of 3D Secure
   1. If transaction is successful store response Id
   2. In case of failure, mark transaction as failure
9. Paynamics sends notification to callback url
10. Verify notification signature
11. Update transaction
12. Update account balance
13. Notify customer of result
