Diff at Instance Level
When you invoke the $diff operation at the instance level (meaning it is invoked on a specific resource ID), it compares two versions of the given resource.
Parameters
- fromVersion=[versionId]—Optional. If specified, compare using this version as the source. If not specified, the immediately previous version is compared.
- includeMeta=true—Optional. If specified, changes to Resource.meta are included in the diff. This element is omitted by default.
