Adds an empty folder
This call requires two body parameters: a name for the new folder and the projectId of the project where you want to add the folder. If you are creating the folder inside an existing folder, then you must also pass the existing folder’s id using the parentId body parameter.
Upon successfully creating a folder, this call returns a 200 code and the id of the new folder.
