Essential for testing state flows without physical hardware.
If you are currently working on an Aptra project, drop a comment below! I’d love to hear how you are handling the transition between older NDC versions and the newer Advance architecture.
For the latest updates and specific implementation details, consulting the official [NCR APTRA™ Advance NDC data sheet](https://ncr.co.il/ israel/2018/02/aptra_advance_ndc_ds.pdf) and Advance NDC Developer’s Guide is crucial for success.
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
| HTTP Status | APTRA Code | Description | Developer Action | |-------------|------------|-------------|------------------| | 400 | NDC-1001 | Missing mandatory element (e.g., PTC ) | Validate request against JSON schema (provided in /schemas folder) | | 409 | NDC-2015 | Offer expired | Re-run AirShopping | | 402 | NDC-3010 | Payment authorization failed | tokenize card again or use different FOP | | 500 | NDC-8005 | Airline NDC gateway timeout | Implement retry with exponential backoff (max 3 retries) |
Proper handling of errors during Chip Power-Up is essential for robust application behavior. 5. Security and Best Practices
Puts the ATM into a waiting pattern while the transaction packet travels to the host. It handles timeouts if the host fails to respond. Developer Implementation Tip Essential for testing state flows without physical hardware
ATM software security demands a rigorous, multi-layered approach due to the high-stakes nature of self-service financial hardware. Encryption Key Management
Developers typically manage configuration payloads in raw text format or via centralized automated deployment utilities. A standard development iteration involves:
The system registry can be utilized to fine-tune terminal behavior, including disabling terminal action analysis for specific scenarios. For the latest updates and specific implementation details,
Embedded securely or processed via cryptography.
Always encrypt the communication channel between the NDC client and the host. Conclusion
