API URL Changes - July 2026

Release dates

• Pre-production: June 2026

• Production: July 2026

• Decommissioning of legacy URLs: December 2026

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.
