Ruby Requires Chilkat v11.7.0+

Box: Search Files with Offset Pagination

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. Search within a folder hierarchy. Box search is indexed and may lag recent changes; use returned upload IDs for immediate follow-up requests. Search uses offset pagination, not folder-list markers.

See the Box API guide for setup and the complete workflow.
