This article provides a complete, practical walkthrough of the Wait Splitout Send 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.

   Automate B2B Lead Generation with n8n and Google Maps
   
   If your business relies on discovering and reaching out to local companies, finding accurate email addresses is an essential yet time-consuming task. Fortunately, with the no-code automation tool n8n, scraping business emails from Google Maps can be automated into a seamless workflow — delivering leads directly to your Google Sheets document.
   
   In this article, we’ll break down how a powerful n8n workflow achieves this, and how you can deploy it to supercharge your lead generation efforts.
   
   🎯 What This Workflow Does
   
   This n8n automation is a fully functional Google Maps email scraper. Based on a list of location-based queries (e.g., "dentist in Beverly Hills"), the workflow:
   
   1. Searches Google Maps for business listings matching the query.
   2. Scrapes the business website URLs from those results.
   3. Filters out irrelevant domains and non-business links (e.g., Google or Wix domains).
   4. Visits each business website.
   5. Extracts any visible email addresses from the HTML content.
   6. Cleans the email list to remove duplicates and irrelevant addresses.
   7. Saves the final email list into a Google Sheets document for easy access.
   
   💡 Ideal Use Cases
   
   - B2B marketers targeting local niches
   - Agencies building email outreach lists for clients
   - Local business services (e.g., SEO, design, or consulting agencies)
   - Sales development reps engaging cold prospects
   
   🧱 How the Workflow Works – Step by Step
   
   1. 📥 Manual Trigger & Query Input
   The process begins with a Manual Trigger node preloaded with search queries — for instance, “santa monica dentist” or “ventura county plumber.” These queries can be customized per your target audience.
   
   2. 🔄 Loop over Queries
   Using Split in Batches, each query is processed one at a time — which helps manage performance and throttles scraping to avoid being blocked by Google.
   
   3. 🔍 Google Maps Search
   An HTTP Request node dynamically builds a Google Maps search URL using the current query. While this doesn't use an official Maps API (avoiding cost and key restrictions), it operates on public search URLs freely accessible in browsers.
   
   4. 🌐 Scrape Website URLs
   Using a custom JavaScript code node, the workflow scrapes website URLs from the raw HTML returned by the Google Maps search result. These are parsed using regular expressions and structured into individual URLs.
   
   5. 🚫 Filter Irrelevant URLs
   To maintain lead quality, the workflow applies a smart filter to exclude URLs from unwanted or unrelated domains (e.g., Google, schema.org, Wixpress, etc.).
   
   6. ♻️ Deduplicate & Loop Through URLs
   The list of valid URLs is deduplicated, then looped through using another Split in Batches node, and each business’s website is requested via an HTTP Request node.
   
   7. ✉️ Scrape Emails from Web Pages
   Each website’s HTML content is inspected with another custom JavaScript node that uses a regular expression to extract any visible email addresses. To minimize false positives, image-based email suffixes (e.g., .png, .jpg) are excluded.
   
   8. 🧹 Clean Email List
   Extracted emails are aggregated from all pages, split into individual email entries, deduplicated, and filtered again — this time filtering out any generic or spammy domains.
   
   9. 📊 Save Results into Google Sheets
   Finally, the useful, cleaned email addresses are appended directly into a designated Google Sheets document. This live asset becomes your constantly growing cold outreach list.
   
   🛠 Setup Instructions
   
   Getting started with this workflow is easy:
   
   1. Prepare Your Query List  
   Use ChatGPT or manual research to build a list of location + industry-based search terms.
   
   2. Open the n8n workflow  
   Deploy the template into your self-hosted or cloud n8n instance.
   
   3. Connect Your Google Sheets Account  
   Use the Google Sheets node authentication to connect your target spreadsheet.
   
   4. Run the Workflow  
   Trigger the workflow and you’ll start seeing emails appear in your sheet within minutes.

   ⚠️ Caveats and Best Practices
   
   - Respect Google’s scraping policy: This workflow scrapes public-facing data but is not suitable for heavy-volume scraping.
   - Include adequate wait times between executions to reduce the chance of being blocked.
   - Always verify and validate emails before adding them to CRM or outreach tools.
   
   🔐 Privacy Note
   
   The workflow accesses public web data only, and email extraction is limited to what is publicly visible via website content. No login or authentication scraping is performed.

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.
