Applies multiple entity changes to a workspace in one call. When creating new entities, their entity IDs must be unique and in correct format. That is, they must start with "new_" and followed by number, e.g. "new_1", "new_2". Example body snippet to create myNewTag under myNewFolder is: "changes": [ { "folder": { "folderId": "new_1", "name": "myNewFolder", ... }, "changeStatus": "added" }, { "tag": { "tagId": "new_2", "name": "myNewTag", "parentFolderId": "new_1", ... }, "changeStatus": "added" } ]
