Uploadcare

Uploadcare is an EU-based, GDPR-friendly media storage and CDN platform. AeroFTP integrates Uploadcare via its native REST + Upload APIs as a first-class StorageProvider. Shipped in v3.7.2 as the 24th protocol.

Connection Settings

Field	Value
REST endpoint	https://api.uploadcare.com (automatic)
Upload endpoint	https://upload.uploadcare.com (automatic)
Public Key	From Uploadcare dashboard > API Keys
Secret Key	From the same panel
Auth	Public + Secret pair (Authorization header)

How to Connect

1. Sign up at uploadcare.com and create a project.
2. In the dashboard, open API Keys and copy both the Public Key and the Secret Key.
3. In AeroFTP, open Discover Services and pick Uploadcare from the Photo & Media tier.
4. Enter the public + secret key pair.
5. Click Connect. AeroFTP lists the project's stored files using the cursor-based pagination flow.

Features

• Cursor-based listing: Native pagination through Uploadcare's REST API. AeroFTP transparently follows the cursor across pages; long lists scroll smoothly.
• Store-once mapping to directories: Uploadcare uses a flat UUID model. AeroFTP layers a directory abstraction on top so you can browse and organize as folders. Files retain their original UUIDs in the Properties dialog.
• Upload: Two-stage commit through /base/ (multipart) followed by /files/{uuid}/storage/ to flag the file as stored. Streaming progress with .aerotmp atomic semantics.
• Download: Direct https://ucarecdn.com/<uuid>/ URLs with optional transformation paths.
• Delete: Soft delete via REST. Files removed from listing but recoverable through the Uploadcare dashboard during the retention window.
• EU data residency: All data physically stored in EU regions (GDPR-compliant by default).

CLI

aeroftp-cli ls --profile "MyUploadcare"
aeroftp-cli put --profile "MyUploadcare" ./assets/*.png /
aeroftp-cli get --profile "MyUploadcare" "/<uuid>" ./local/
aeroftp-cli sync --profile "MyUploadcare" ./media /

Tips

• The public key is safe to embed in client-side code (signed upload widgets, etc.). The secret key must remain server-side. AeroFTP keeps both in the encrypted vault.
• Uploadcare's CDN supports image transformations via path segments (/-/preview/300x300/, etc.). Append them to share links as needed.
• Free tier includes 3 GB of stored media and unlimited bandwidth for the first 30 days; check the dashboard for the current pricing.
• Activity Log surfaces the project public-key hostname in the clear (e.g. Authenticated as api.uploadcare.com/<project>); the secret key remains masked.

Common Issues

Problem	Cause	Solution
401 Unauthorized	Wrong public/secret key pair	Regenerate the keys in the dashboard and reconnect.
409 Conflict on delete	File still has active webhooks or pending operations	Wait for pending operations to settle, retry the delete.
Files visible in Uploadcare web but not in AeroFTP	Files are uploaded but not committed to storage	AeroFTP's put flow always commits. Check the dashboard's "Pending" filter for orphaned uploads.
