To generate a presigned URL, you call the storage API endpoint designed for this task, which creates a secure link allowing clients to upload files directly to the bucket. This workflow ensures scalable and auditable file handling without exposing backend credentials.

A presigned URL is a time-limited link that grants secure upload or download access to a storage bucket. You need it in a REST API when building a media upload service that accepts user files directly, bypassing server-side data transfer to ensure scalable storage.

Yes, you can manage file visibility and metadata after the upload completes. The REST API provides dedicated endpoints to update metadata, change access levels between public, private, protected, and shared, and list or view detailed file records.

Yes, the storage workflow supports single, multiple, and multipart uploads using presigned URLs. This allows your application to handle large files and batch uploads efficiently while maintaining secure, auditable file handling at scale.

The best way to build a secure media upload service is using a structured backend storage guide that orchestrates presigned URLs and bucket management. This approach provides visibility controls and registers rich metadata, enabling searchable, auditable file records.
