AI-Powered AWS S3 Manager with Audit Logging in n8n (Slack/ChatOps Workflow)

This n8n workflow empowers users to manage AWS S3 buckets and files using natural language via Slack or chat platforms. Equipped with an OpenAI-powered Agent and integrated audit logging to Google Sheets, it supports operations like listing buckets, copying/deleting files, managing folders, and automatically records every action for compliance and traceability.

👥 Who’s it for

This workflow is built for:

• DevOps engineers who want to manage AWS S3 using natural chat commands.
• Technical support teams interacting with AWS via Slack, Telegram, etc.
• Automation engineers building ChatOps tools.
• Organizations that require audit logs for every cloud operation.

Users don’t need AWS Console or CLI access — just send a message like “Copy file from dev to prod”.

⚙️ How it works / What it does

This workflow turns natural chat input into automated AWS S3 actions using an OpenAI-powered AI Agent in n8n.

🔁 Workflow Overview:

1. Trigger : A user sends a message in Slack, Telegram, etc.
2. AI Agent :
   • Interprets the message
   • Calls one of 6 S3 tools:
     • ListBuckets
     • ListObjects
     • CopyObject
     • DeleteObject
     • ListFolders
     • CreateFolder
3. S3 Action : Performs the requested AWS S3 operation.
4. Audit Log : Logs the tool call to Google Sheets using AddAuditLog:
   • Includes timestamp, tool used, parameters, prompt, reasoning, and user info.

🛠️ How to set up

Step-by-step Setup:

1. Webhook Trigger

   • Slack, Telegram, or custom chat platform → connects to n8n.

2. OpenAI Agent

   • Model: gpt-4 or gpt-3.5-turbo
   • Memory: Simple Memory Node
   • Prompt: Instructs agent to always follow tool calls with an AddAuditLog call.

3. AWS S3 Nodes

   • Configure each tool with AWS credentials.
   • Tools:
     • getAll: bucket
     • getAll: file
     • copy: file
     • delete: file
     • getAll: folder
     • create: folder

4. Google Sheets Node

   • Sheet: AWS S3 Audit Logs
   • Operation: Append or Update Row
   • Columns (must match input keys):
     • timestamp, tool, status, chat_prompt, parameters, user_name, tool_call_reasoning

5. Agent Tool Definitions

   • Include AddAuditLog as a 7th tool.
   • Agent calls it immediately after every S3 action (except when logging itself).

✅ Requirements

• n8n instance with AI Agent feature
• OpenAI API Key
• AWS IAM user with S3 access
• Google Sheet with required columns
• Chat integration (Slack, Telegram, etc.)

🧩 How to customize the workflow

Feature	Customization Tip
🌎 Multi-region S3	Let users include region in the message or agent memory
🛡️ Restricted actions	Use memory/user ID to limit delete/copy actions
📁 Folder filtering	Extend ListObjects with prefix/suffix filters
📤 Upload file	Add PutObject with pre-signed URL support
🧾 Extra logging	Add IP, latency, error trace to audit logs
📊 Reporting	Link Google Sheet to Looker Studio for audit dashboards
🚨 Security alerts	Notify via Slack/Email when DeleteObject is triggered
