To list contents of a folder in the repository use the listNodeChildren method of the NodesApi, which is one of the main APIs used when you want to manipulate folders and files.
For more information about this ReST API endpoint, see List Contents of a Folder.
For a description of the common parameters, such as include, see Common Parameters.
