🔍 Testing an Endpoint

When adding or editing an endpoint in Upper, you can tap the Test button to verify that the connection and credentials are working correctly.

This test sends a “List Objects” request to the configured endpoint — which means the Default Bucket field must be filled in for the test to work.

If the test fails, check the following:

• Endpoint URL — Ensure the URL is correct and uses the proper format (e.g., https://…)
• Region — Some providers require a specific region string that must match exactly
• Default Bucket — This field is required for the test and must reference an existing bucket
• Credentials — Make sure your access key and secret are correct and active

<aside> ⚠️

Note: Your credentials must have the necessary permissions (e.g. s3:ListBucket, s3:GetObject, s3:PutObject, etc.) to use all available actions in Shortcuts.

☁️ Credentials Aren’t Syncing Across Devices

Upper automatically syncs your endpoints via iCloud. However, because credentials are sensitive, they’re securely stored in your device’s Keychain and synced separately using iCloud Keychain.
