The API supports some filtering (status, archived, parent, milestone, deleted) for fetching Actions via this endpoint: https://developers.hive.com/reference/workspacesworkspaceidactions It would be valuable to be able to filter by custom field values in API requests. For example, a request like below would return items which have a custom field with ID "Foo" and a value for that custom field set to "Bar": GET /api/v2/workspaces/MY_WORKSPACE_ID/actions?filters[Foo]=Bar
