This documentation is for integrations built with legacy access to the API, meaning that access credentials were provided directly by Trimble (or an earlier version of API Cloud) in or before early 2026 and not created in the Developer Console.

For new API integrations, use the Latest Version.

API Deprecation Timeline

No timeline has yet been determined for API integrations developed in or before early 2026 to be migrated to the new API.
