API URL Changes - August 2026

Release dates

• Pre-production: July 2026 (TBC)

• Production: August 2026 (TBC)

• Decommissioning of legacy URLs: December 2026 (TBC)

Summary

• Participants must update their internet-facing pre-production and production API endpoints to new URLs.
• HTTPS port change: All new API URLs will use the default HTTPS port 443 instead of the old port 9319, eliminating the need to specify the port number in connections.
• Tables list old and new URLs for NEM, WEM, and GAS APIs, showing migration from old to new URLs without port specification.
