Pin the API version an integration was built against (date-based, e.g. 2026-07-01). Omit to use the current version. Public URL paths stay stable and unversioned; breaking changes ship under a new dated version and are announced with Deprecation and Sunset response headers. The served version is echoed in every response's Unifapi-Version header. Policy: https://unifapi.com/versioning.md
