Box: Query Documents by Customer Metadata

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. Query the projectDocument enterprise template using a parameterized customer ID and marker pagination. Requires the template and access to matching content; metadata queries are distinct from full-text search. The enterprise scope ID is resolved from the current user profile; enterprise membership and the pre-existing template are required.

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