N8N Tools - S3 Enhanced

Enhanced S3 operations with presigned URLs, multipart upload, and advanced features

Overview

The node "N8N Tools - S3 Enhanced" provides a comprehensive set of operations to interact with S3-compatible object storage services. It supports advanced features such as generating presigned URLs and POSTs for secure temporary access, multipart uploads for large files, bucket and object management, ACL and tagging configurations, lifecycle policies, replication, encryption, website hosting settings, analytics, inventory, and more.

This node is beneficial in scenarios where you need programmatic control over S3 buckets and objects beyond simple upload/download, including managing bucket policies, configuring notifications, or performing complex queries on object content.

Practical examples:

  • Generating a presigned URL to allow temporary download access to a private file without exposing credentials.
  • Uploading large files using multipart upload to improve reliability and performance.
  • Retrieving the notification configuration of a bucket to monitor events like object creation.
  • Managing bucket lifecycle rules to automate data retention policies.

For the provided Resource "Default" and Operation "Get Bucket Notification", this node retrieves the notification configuration of a specified S3 bucket, which includes topic, queue, and event bridge configurations.

Properties

Name Meaning
Bucket Name Name of the S3 bucket from which to get the notification configuration

Output

The output JSON object for the "Get Bucket Notification" operation has the following structure:

  • bucket: The name of the bucket queried.
  • topicConfigurations: Array of topic-based notification configurations associated with the bucket.
  • queueConfigurations: Array of queue-based notification configurations associated with the bucket.
  • eventBridgeConfiguration: Configuration related to EventBridge notifications for the bucket.

This output provides detailed information about how the bucket is configured to send notifications on various events, useful for monitoring or triggering workflows based on bucket activity.

Dependencies

  • Requires an S3-compatible service endpoint accessible via AWS SDK v3 client.
  • Requires valid API credentials (access key ID and secret access key) with permissions to read bucket notification configurations.
  • The node expects the user to configure these credentials securely within n8n's credential management system.
  • No additional environment variables are explicitly required beyond standard AWS/S3 credentials.

Troubleshooting

  • Common issues:

    • Invalid or missing credentials will cause authentication failures.
    • Insufficient permissions on the bucket may result in access denied errors.
    • Incorrect bucket name or non-existent bucket will cause errors indicating the bucket cannot be found.
    • Network connectivity issues to the S3 endpoint can cause connection errors.
  • Error messages and resolutions:

    • "Access denied. Check your credentials and permissions." — Ensure the API key has permission to call GetBucketNotificationConfiguration.
    • "Cannot connect to endpoint. Check your endpoint URL and network connection." — Verify the endpoint URL and network accessibility.
    • "S3 operation failed: <message>" — General catch-all error; check the detailed message for specifics.
    • "Invalid notification configuration JSON format" — Not applicable here since this operation only reads configuration, but relevant for setting notifications.
