Get a list of file versions on legal hold for a legal hold assignment.
Due to ongoing re-architecture efforts this API might not return all file versions for this policy ID.
Instead, this API will only return file versions held in the legacy architecture. Two new endpoints will available to request any file versions held in the new architecture.
For file versions held in the new architecture, the GET /legal_hold_policy_assignments/:id/file_versions_on_hold API can be used to
return all past file versions available for this policy assignment, and the
GET /legal_hold_policy_assignments/:id/files_on_hold API can be used to
return any current (latest) versions of a file under legal hold.
The GET /legal_hold_policy_assignments?policy_id={id} API can be used to
find a list of policy assignments for a given policy ID.
Once the re-architecture is completed this API will be deprecated.
