Aptra Advance Ndc Developer-s Guide [hot] Now

Associating visual assets or text strings with the new states.

When modifying state tables, developers typically edit a state data file configuration. For example, a standard PIN entry state configuration dictates: The screen ID to display. The timeout values (usually 20–30 seconds).

You can pause the execution of an NDC state to run a local executable or script (e.g., verifying a local biometric scan) before returning control to the standard host flow. Graphic User Interface (GUI) Customization aptra advance ndc developer-s guide

When a transaction fails, check NcrNdc.log first. If the host message arrived but the ATM failed to dispense, the issue is an NDC State parsing error or a hardware breakdown. If no message arrived, verify TCP/IP port routing and SSL/TLS handshake configurations.

Interacts directly with the hardware EPP to ensure the clear-text PIN never enters the terminal's main memory or operating system layers. PINs are instantly encrypted into Triple DES (3DES) or AES PIN blocks. Associating visual assets or text strings with the

Embedded securely or processed via cryptography.

Here is a complete mini-client from the guide’s appendix: The timeout values (usually 20–30 seconds)

| HTTP Status | Code | Meaning | Action | |-------------|------|---------|--------| | 400 | INVALID_PAX_DOB | Date of birth format invalid | Use YYYY-MM-DD | | 401 | TOKEN_EXPIRED | Access token expired | Re-authenticate | | 429 | RATE_LIMITED | Too many requests | Implement exponential backoff | | 500 | AIRLINE_TIMEOUT | Airline NDC gateway unreachable | Retry with idempotency key |

: Detailed specifications for implementing the NDC protocol to manage transaction flow and device-level commands.

Third, the guide offers a pathway for hardware abstraction. Through the NDC layer, Aptra Advance communicates with the ATM’s peripherals—dispensers, card readers, and pin pads. The developer’s guide explains the command sets required to trigger these hardware events safely. This ensures that a developer does not need to know the machine code for a specific dispenser model; they only need to understand the high-level function calls described in the guide.
