Notify User in Slack of Quarantined Email and Create Jira Ticket (if opened)

This n8n workflow automates the process of notifying a user via Slack about a quarantined email and, if the Slack message is opened, creating a corresponding Jira ticket. This helps streamline the handling of potentially malicious or unwanted emails, ensuring timely communication and action.

What it does

1. Receives Quarantined Email Data: The workflow is triggered by an incoming webhook, expecting data related to a quarantined email.
2. Notifies User in Slack: It sends a direct message to the affected user on Slack, informing them about the quarantined email.
3. Checks for Slack Message Interaction: The workflow then uses an HTTP Request node to check if the sent Slack message was opened by the user.
4. Conditional Jira Ticket Creation:
   • If the Slack message was opened: A Jira ticket is automatically created to track the quarantined email, indicating that the user has seen the notification.
   • If the Slack message was NOT opened: No Jira ticket is created, assuming no further action is immediately needed from the user's side (or a different follow-up process might be in place).

Prerequisites/Requirements

• n8n Instance: A running n8n instance.
• Slack Account: A Slack workspace and a Slack App configured with appropriate permissions to send direct messages. You will need a Slack API Token.
• Jira Software Account: Access to a Jira Software instance with permissions to create issues. You will need Jira API credentials (e.g., API token or username/password).
• Webhook Source: An external system or service that can send quarantined email data to the n8n webhook URL.
• Slack Message ID: The incoming webhook data or a preceding node in your actual implementation would need to provide the Slack message ID to check its status. (Note: The provided JSON does not explicitly show how the Slack message ID is captured or used, but the "HTTP Request" node implies checking a Slack API endpoint which would typically require this).

Setup/Usage

1. Import the Workflow:
   • Copy the provided JSON workflow.
   • In your n8n instance, go to "Workflows" and click "New".
   • Click the "Import from JSON" button and paste the workflow JSON.
2. Configure Credentials:
   • Slack: You will need to create a Slack credential. Select the "Slack API" credential type and provide your Slack Bot User OAuth Token.
   • Jira Software: You will need to create a Jira Software credential. Select the appropriate credential type (e.g., "Jira API Token" or "Jira Basic Auth") and enter your Jira URL, username/email, and API token/password.
3. Configure Nodes:
   • Webhook (Node 47):
     • Copy the "Webhook URL" after saving the workflow. This URL will be used by your external system to send quarantined email data to n8n.
     • Ensure the "HTTP Method" and "Response Mode" match what your external system expects.
   • Slack (Node 40):
     • Select your configured Slack credential.
     • Set the "Channel" to the user's Slack ID (e.g., @{user_id}). This would likely come from the incoming webhook data.
     • Customize the "Text" of the message to include relevant details about the quarantined email (e.g., sender, subject, reason).
   • HTTP Request (Node 19):
     • This node is intended to check if the Slack message was opened. You will need to configure it to call the Slack API's conversations.history or a similar endpoint, passing the channel and ts (timestamp of the sent message) to check for reactions or if the message was read. This will likely involve extracting the ts from the output of the previous Slack node.
     • Set the "Authentication" to use your Slack API token if not already handled by the Slack node itself.
   • If (Node 20):
     • This node will evaluate the response from the "HTTP Request" node. Configure the condition to check for a specific indicator that the Slack message was opened (e.g., a specific reaction, or by comparing timestamps if the Slack API provides read receipts).
   • Jira Software (Node 77):
     • Select your configured Jira Software credential.
     • Configure the "Resource" to "Issue" and "Operation" to "Create".
     • Set the "Project Key" and "Issue Type".
     • Customize the "Summary" and "Description" of the Jira ticket with details from the quarantined email data, potentially including a link to the Slack message.
   • Code (Node 834): This node is currently empty. It can be used for any custom data transformation, logging, or advanced logic if needed. For instance, to parse the incoming webhook data or format the output for Slack/Jira.
4. Activate the Workflow: Toggle the workflow to "Active" in the n8n editor.

Now, whenever your external system sends data about a quarantined email to the webhook, this workflow will execute, notify the user, and conditionally create a Jira ticket.
