How to Retrieve Downloads by Category in jDownloads via Plugin/API?

[henryclinton]

I'm developing a custom extension that needs to fetch all files or downloads assigned to certain categories within jDownloads. I've checked the documentation but haven't found a clear solution yet.
Does jDownloads provide an official API, helper class, or built-in function for retrieving downloads by category ID?
If anyone has experience integrating third-party plugins with jDownloads, I'd appreciate examples or best practices for handling this efficiently.
