This article provides a complete, practical walkthrough of the Webhook Code Create Webhook n8n agent. It connects HTTP Request, Webhook across approximately 1 node(s). Expect a Intermediate setup in 15-45 minutes. One‑time purchase: €29.

What This Agent Does

This agent orchestrates a reliable automation between HTTP Request, Webhook, handling triggers, data enrichment, and delivery with guardrails for errors and rate limits.

It streamlines multi‑step processes that would otherwise require manual exports, spreadsheet cleanup, and repeated API requests. By centralizing logic in n8n, it reduces context switching, lowers error rates, and ensures consistent results across teams.

Typical outcomes include faster lead handoffs, automated notifications, accurate data synchronization, and better visibility via execution logs and optional Slack/Email alerts.

How It Works

The workflow uses standard n8n building blocks like Webhook or Schedule triggers, HTTP Request for API calls, and control nodes (IF, Merge, Set) to validate inputs, branch on conditions, and format outputs. Retries and timeouts improve resilience, while credentials keep secrets safe.

   In the world of modern cybersecurity, response time is everything. Once a malicious or suspicious email reaches a user’s inbox, quick decisions must be taken to secure the endpoints and notify stakeholders. Responding manually to each incident isn't scalable, especially in large organizations. Enter n8n—a powerful, open-source workflow automation tool—and a targeted integration with Sublime Security, Slack, and Jira to streamline security operations.
   
   This article explores a complete security automation workflow built in n8n that empowers security operations (SecOps) teams to reduce threat response times, keep users informed, and log incident details efficiently. The workflow is aptly named: Notify_user_in_Slack_of_quarantined_email_and_create_Jira_ticket_if_opened.
   
   Overview: The Problem It Solves
   
   Phishing emails and malware often arrive discretely, targeting unsuspecting employees before they can be intercepted. While Sublime Security does a stellar job detecting and quarantining suspicious messages, it's critical that users and the internal IT team stay informed when such activity occurs—especially if the email was opened before quarantine. That’s what this n8n workflow addresses.
   
   Triggered by Sublime Security Alerts
   
   The starting point of the workflow is a webhook node in n8n called "Receive Sublime Security Alert." This webhook listens for alerts from Sublime Security triggered by predefined rules, particularly those with auto-quarantine enabled. When an alert comes in, the message ID of the flagged email is extracted and used to fetch full message details via a follow-up HTTPS request to Sublime Security’s API.
   
   Key Information Extracted:
   
   - Email subject
   - Sender and recipient addresses
   - When the email was received and read
   - Security rules that flagged the email
   
   Check if the Email Was Read Before Quarantine
   
   The crux of the automation logic lies in determining whether the recipient opened the email before it was quarantined. This is handled by a decision node: "has email been opened?". If the email remains unread, the workflow ends quietly. But if opened, it indicates a potentially higher security risk.
   
   At this point, two things happen:
   
   1. The flagged rules are formatted into a markdown table for context.
   2. A Jira ticket is automatically created to log and escalate the incident.
   
   Creating an Informative Jira Ticket
   
   The "Jira Software" node builds a detailed issue template including critical fields such as:
   
   - Email subject and sender info
   - Time of read and quarantine
   - A table summarizing the triggered rules
   - A message for IT teams to investigate further
   
   This ensures the security operations team has immediate access to the intel they need to triage and respond.
   
   Notifying the User in Slack
   
   In parallel with the Jira workflow, a user-focused branch takes shape. Using the recipient's email address, the workflow attempts to match the user in Slack by calling the Slack API’s users.lookupByEmail endpoint. If a match is found, the "Found, notify user" node sends a direct Slack message explaining the event clearly:
   
   - The email was flagged and quarantined
   - Sender and subject line
   - What to do if the email seems legitimate
   - Whom to contact (IT/security)
   
   If no Slack user is found, the workflow safely ends via a no-op (no operation) node.
   
   Why This Automation Matters
   
   This multi-service automation does more than just alert—it becomes a mini incident response playbook in motion, ensuring:
   
   - The target user is notified swiftly—limiting confusion or concern over missing emails.
   - The security team is proactively engaged if the malicious email was actually opened.
   - All parties—the user and IT—are aligned without manual coordination.
   
   With phishing attacks and social engineering scams continually evolving, automations like this reduce human overhead and reinforce a responsive security posture.
   
   Tech Stack Summary
   
   This workflow harnesses the following platforms:
   
   - Sublime Security for email scanning, alerting, and quarantining
   - Slack as the communication channel for notifying end users
   - Jira Software as the incident tracking solution
   - n8n as the orchestration engine to tie it all together
   
   Conclusion
   
   The integration of n8n with Sublime Security, Slack, and Jira is a model use case for modern security automation. By combining real-time monitoring, internal notifications, and issue tracking, this workflow achieves faster response times, reduces manual effort, and improves organizational awareness of email-based threats.
   
   As cybersecurity threats become more sophisticated, automation is no longer optional—it’s essential. This workflow is just one example of how powerful and flexible n8n can be when tackling real-world security challenges.
   
   Ready to try it in your organization? All it takes is configuring a few credentials and SOPs, and your SecOps automation can be up and running in hours—not weeks.

5. Set credentials for each API node (keys, OAuth) in Credentials.
6. Run a test via Execute Workflow. Inspect Run Data, then adjust parameters.
7. Enable the workflow to run on schedule, webhook, or triggers as configured.

Tips: keep secrets in credentials, add retries and timeouts on HTTP nodes, implement error notifications, and paginate large API fetches.

Validation: use IF/Code nodes to sanitize inputs and guard against empty payloads.

Why Automate This with AI Agents

AI‑assisted automations offload repetitive, error‑prone tasks to a predictable workflow. Instead of manual copy‑paste and ad‑hoc scripts, your team gets a governed pipeline with versioned state, auditability, and observable runs.

n8n’s node graph makes data flow transparent while AI‑powered enrichment (classification, extraction, summarization) boosts throughput and consistency. Teams reclaim time, reduce operational costs, and standardize best practices without sacrificing flexibility.

Compared to one‑off integrations, an AI agent is easier to extend: swap APIs, add filters, or bolt on notifications without rewriting everything. You get reliability, control, and a faster path from idea to production.

Best Practices

• Credentials: restrict scopes and rotate tokens regularly.
• Resilience: configure retries, timeouts, and backoff for API nodes.
• Data Quality: validate inputs; normalize fields early to reduce downstream branching.
• Performance: batch records and paginate for large datasets.
• Observability: add failure alerts (Email/Slack) and persistent logs for auditing.
• Security: avoid sensitive data in logs; use environment variables and n8n credentials.

FAQs

Can I swap integrations later? Yes. Replace or add nodes and re‑map fields without rebuilding the whole flow.

How do I monitor failures? Use Execution logs and add notifications on the Error Trigger path.

Does it scale? Use queues, batching, and sub‑workflows to split responsibilities and control load.

Is my data safe? Keep secrets in Credentials, restrict token scopes, and review access logs.
