Large File Transfer API

Developers can use FileFast as a file transfer layer for internal tools, dashboards, automation, and customer workflows.

The API supports authenticated uploads, file listing, folders, deletion, presigned uploads, and file information endpoints.

Why use FileFast?

  • Authenticated requests: Generate an API token from your profile and use Bearer authentication.
  • Upload workflows: Use direct upload or presigned upload flows depending on your integration.
  • Folder management: Create folders and organize files from your own tools.
  • File info: Check file metadata and availability from your application.
