6 days ago by Morales, Jennifer
This Changelog post outlines the updates made to the Newline Platform in February 2026.
What We Improved
Newline API
- New ACH SEC Code Update (IAT): Approved Programs can now receive IAT coded ACH payments with all included IAT addenda details on the Transaction Endpoint. These IAT ACH payments are compatible with Virtual Reference Numbers, Client Authorization, and the Returns Endpoint.
Newline Dashboard
- Newline Status Dev Docs Page: This addition provides developers with clear, structured visibility into system health, uptime, and incident history, supporting our ongoing efforts around transparency and reliability across Newline services.
What We Fixed
Newline API
- ACH Validation Aligned to Eastern Time: Enhanced ACH Effective Entry Date validation to consistently evaluate cutoffs using Eastern Time instead of UTC time.
- Updated POST /returns 201 Response Example in API Documentation: Refined the API documentation to ensure the POST /returns 201 response example reflects the accurate, expected format.
- Wire Transaction Return Data Enhancement: Improved the mock wire transaction payload to ensure debit party and routing information is fully included for return processing workflows.
- Originator Account Last‑Four Value Standardization for Wire Transactions: Updated wire processing to consistently store the detokenized last four digits of originator account numbers for greater clarity and accuracy.
Why It Matters
These updates improve the clarity, reliability, and overall usability of the Newline Platform. The API refinements strengthen how ACH data is processed and validated, while enhancements to the Dashboard increase developer visibility into system health and provide more accurate, consistent information during transaction workflows. Together, these improvements help developers build and troubleshoot with greater confidence and efficiency.
We are committed to continuously improving our documentation to help clients create seamless financial experiences. For questions or further details, please contact Jennifer Morales
