This article provides a complete, practical walkthrough of the Splitout Webhook Automation 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.

   Build an Email Scraping API with n8n: A Step-by-Step Guide
   
   Email scraping can be a powerful tool for lead generation, domain analysis, or contact discovery — if done responsibly and ethically. While many solutions require writing custom scripts with Python or JavaScript, n8n offers a no-code/low-code alternative. In this article, we’ll walk you through how to build an API that scrapes email addresses from any given website, using just n8n.
   
   Best of all, you don’t need any additional libraries or services; everything runs directly within your n8n instance.
   
   🔧 What You’ll Build
   
   You’ll create an API endpoint using a webhook. When a user sends a website URL as a query parameter, the workflow fetches the HTML content of that website, extracts any email addresses using a regular expression, and returns them to the requester after removing duplicates.
   
   💡 Key Use Cases:
   - Quick extraction of contact emails from company sites
   - Verifying the presence of emails on partner or affiliate landing pages
   - Building internal tools for lead research
   
   📋 Workflow Overview
   
   Below is how the n8n workflow operates, step-by-step:
   
   1. 📨 Webhook Input
      The journey begins with the Webhook node. This node receives HTTP GET requests with one essential query parameter: Website. For example:
      ```
      http://localhost:5678/webhook/ea568868-5770-4b2a-8893-700b344c995e?Website=http://example.com
      ```
   
   2. 🌐 Fetch Website Content
      A subsequent HTTP Request node retrieves the HTML content from the provided URL. It reads the Website parameter and loads the full page.
   
   3. 🧠 Extract Emails
      A Set node applies a JavaScript regex filter to the raw HTML using the following pattern:
      ```
      /(?:[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,})/g
      ```
      This standard email regex identifies all email-like strings on the page and stores them in an Email array.
   
   4. ✂️ Split Array into Individual Emails
      The Split Out node deconstructs the Email array into separate items for individual processing.
   
   5. 🧪 Filter Non-Empty Email Results
      The If node checks that the Email field is not empty to prevent unnecessary processing.
   
   6. 🔁 Remove Duplicates
      The Remove Duplicates node ensures the final response only contains unique email addresses, eliminating multiple instances of the same contact.
   
   7. 📤 Return Results
      The Respond to Webhook node formats and returns the final list of unique email addresses to the caller.
   
   🧪 Example Response:
   Calling the endpoint as shown above might return a response resembling:
   
   ```json
   [
     "info@example.com",
     "contact@company.com"
   ]
   ```
   
   If no emails are found, the workflow simply returns a message like "workflow successfully executed," indicating the process was successful but yielded no results.
   
   📍 Important Notes
   
   - Always use http:// or https:// in your Website query parameter. Otherwise, the HTTP Request may fail.
   - Email scraping should be done with proper consent and in accordance with privacy laws like GDPR or CAN-SPAM.
   - Content behind JavaScript-rendered sources (like SPAs) may not be captured accurately with a basic HTTP Request node.
   
   🧩 Customization Ideas
   
   Thanks to n8n’s flexible architecture, this workflow can be enhanced in multiple ways:
   
   - Add a database node to log every request.
   - Use Filter or Switch nodes to process only specific domain types or email patterns.
   - Integrate a data enrichment API to verify email validity.
   - Schedule the workflow to monitor email changes on a domain repeatedly.
   
   📦 Conclusion
   
   This workflow demonstrates how n8n can be used to build sophisticated data extraction tools without writing traditional code. By chaining together a webhook, HTTP request, regex matching, and some array manipulation, you’ve created an efficient, re-usable API for scraping emails from open websites.
   
   Whether you're exploring lead-generation tools or creating internal utilities, this email grabbing workflow is a powerful addition to your n8n toolkit.
   
   🧠 Happy automating!

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.
