Less than to read
Important Notice: Deprecation of Sage Accounting API V3
We’d like to inform you that API V3 is scheduled for deprecation on 31st July 2026. To ensure continued functionality and access to the latest features and improvements, we strongly encourage you to begin migrating your applications to API V3.1.
Why this matters:
API V3.1 offers enhanced performance, improved consistency, and better support for future development. After the deprecation date, API V3 will no longer be supported or accessible. Migration Support: To assist with your transition, we’ve prepared a comprehensive migration guide: Migrate from V3 to V3.1
If you have any questions or need help with the migration process, our developer support team is here to help. Please contact us at [email protected] for individual assistance.
