Box: Create a Folder and Capture Its ID
See more Box Examples
Run the reusable setup once per HttpCurl object, then select names and execute the operation. The setup is repeated here only to make this published example independently runnable. Create Project Documents under the root child named documents. The new folder ID is captured for later operations; conflicts stop the example. Set parent_name to / to create directly under root.
See the Box API guide for setup and the complete workflow.
