AWS S3 Email Commander n8n Workflow

This n8n workflow allows you to manage your AWS S3 buckets and files directly from your email inbox. By sending specific commands via email, you can trigger actions within AWS S3, such as creating or deleting buckets and organizing files.

What it does

This workflow automates AWS S3 management tasks by:

1. Listening for Incoming Emails: It acts as an IMAP email trigger, constantly monitoring a specified email inbox for new messages.
2. Filtering Email Commands: It uses an "If" node to check if the incoming email's subject or body contains specific keywords or patterns that indicate an AWS S3 command.
3. Routing Commands: A "Switch" node then routes the email to the appropriate AWS S3 action based on the identified command (e.g., "create bucket", "delete file").
4. Executing AWS S3 Actions: An "AWS S3" node performs the requested action on your AWS S3 account.
5. Sending Email Confirmations: After executing the command, it sends a confirmation or error email back to the sender using the "Send Email" node, indicating the success or failure of the operation.
6. Custom Logic (Code Node): A "Code" node is included, likely for parsing email content, extracting parameters (like bucket names, file paths), or constructing dynamic responses before interacting with AWS S3 or sending emails.
7. Informational Sticky Note: A "Sticky Note" provides additional context or instructions within the workflow itself.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running instance of n8n.
• IMAP Email Account: An email account configured for IMAP access, which n8n will monitor.
• SMTP Email Account: An email account configured for sending emails (SMTP) to send confirmations.
• AWS Account: An active AWS account with programmatic access keys.
• AWS S3 Permissions: The AWS credentials used in n8n must have the necessary permissions to perform the desired actions (e.g., s3:CreateBucket, s3:DeleteObject, s3:PutObject).

Setup/Usage

1. Import the Workflow: Download the JSON provided and import it into your n8n instance.
2. Configure Email Trigger (IMAP):
   • Set up your IMAP credentials for the email account you want to monitor.
   • Specify the folder to watch for new emails.
3. Configure Send Email (SMTP):
   • Set up your SMTP credentials for sending confirmation emails.
   • Adjust the "To" field to send replies to the original sender (e.g., {{ $json.from }}).
4. Configure AWS S3 Node:
   • Set up your AWS credentials (Access Key ID and Secret Access Key).
   • Choose the AWS region.
   • The operations within the AWS S3 node will be dynamically configured by the preceding "Code" and "Switch" nodes based on the email commands.
5. Customize "If" and "Switch" Nodes:
   • Modify the conditions in the "If" node to recognize your desired email commands (e.g., "create bucket", "delete file", "upload file").
   • Adjust the "Switch" node to route to different AWS S3 operations based on these commands.
6. Customize "Code" Node:
   • The "Code" node is crucial for parsing the email subject/body to extract parameters like bucket names, file names, or content. You will need to write JavaScript code here to interpret your specific email command syntax.
7. Activate the Workflow: Once configured, activate the workflow.

Now, you can send emails to the configured IMAP address with your custom commands in the subject or body, and n8n will execute the corresponding AWS S3 actions.
