Objective-C Requires Chilkat v11.7.0+
Objective-C
Box: Rename and Move a File
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. Change the name and parent of an existing file in one update. The destination folder must be accessible; moving content may change inherited access.
See the Box API guide for setup and the complete workflow.
