High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do presigned URLs work for secure file uploads in a backend API?▼

Presigned URLs allow clients to upload files directly to backend storage securely, bypassing server traffic. The Skill generates these URLs and registers file metadata via REST API endpoints for lifecycle management.

How do I handle multipart uploads for large files via a REST API?▼

Multipart upload support allows large files to be split into chunks and sent to backend storage via REST API endpoints, ensuring reliable, resumable transfers and metadata registration for each completed file.

What visibility and access levels can I set for stored files?▼

Stored files support public, private, protected, and shared visibility levels. These access patterns govern retrieval permissions and enable controlled CDN-backed downloads across different application user roles.

Can I use CDN-backed downloads with private file storage?▼

Yes, CDN-backed downloads work with private file storage. Protected and shared visibility levels apply access governance while leveraging CDN delivery for fast, secure file retrieval.

What's the best way to manage file metadata and lifecycle in backend storage?▼

Managing file metadata in backend storage involves registering file details during upload and using REST API endpoints to list, detail, update, and delete files throughout their lifecycle.
