This article provides a complete, practical walkthrough of the Http Htmlextract 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 Your Hacker News Feed: How to Track “Show HN” Posts Daily with n8n
   
   If you're a frequent reader of Hacker News, you already know the value of "Show HN" posts—the place where developers showcase their side projects and new creations. But keeping up with these posts manually every day? That’s a productivity bottleneck. What if you could get a daily summary of these trending posts delivered straight to your inbox?
   
   With n8n, a powerful no-code workflow automation tool, you can set up an automated pipeline to scrape Hacker News, extract “Show HN” posts, and email yourself a curated list—all without writing complex scripts. Here’s how it works and how you can implement it in your own workflow.
   
   📌 The Goal: Daily Email of “Show HN” Posts
   
   This automation runs once each day, scrapes the Hacker News homepage, filters out posts that start with “Show HN:”, and sends a nicely formatted email with those entries. It’s a quick and efficient way to stay in the loop without spending 20 minutes scrolling through news.ycombinator.com.
   
   🛠️ The Workflow Breakdown
   
   Let’s walk through the main components of the n8n workflow:
   
   1. Cron Node: Scheduled Trigger
   The workflow begins with a Cron node configured to fire every day at 1:00 PM (13:00). This node acts as your daily trigger, kicking off the rest of the sequence like clockwork.
   
   2. HTTP Request: Scrape Hacker News
   Next, an HTTP Request node fetches the HTML content of https://news.ycombinator.com/. Rather than using a structured API (which Hacker News does provide for advanced users), this workflow performs direct HTML scraping for flexibility and simplicity.
   
   3. HTML Extract Items
   Using the HTML Extract node, the workflow targets all listing items on the Hacker News homepage by selecting elements with the CSS class tr.athing. This captures each post’s row as raw HTML data.
   
   4. HTML Extract Data
   The extracted rows are then parsed for specific information:
   - Title (via anchor tags)
   - URL (from href of elements with the class storylink)
   - Rank (using the CSS class .rank)
   
   Each post's metadata is neatly extracted into structured JSON, preparing it for conditional filtering.
   
   5. IF Node: Filter for “Show HN”
   The IF node checks whether the title field contains the string “Show HN:”. Only items that match this condition are passed to the next stage.
   
   6. Function Node: Format the Email
   The filtered items are looped through in a Function node that formats each post into a readable string. The output text looks something like this:
   
   Currently trending "Show HN":
   
   1. Show HN: Markdown Editor in Rust
   https://example.com/project/markdown-rust
   
   2. Show HN: Minimal To-Do CLI
   https://example.com/project/todo-cli
   
   This is then returned as an object to be sent via email.
   
   7. Send Email Node
   Finally, the formatted text is sent via n8n’s Email Send node. The subject line is set to “Trending Show HN,” and the content is populated with the emailText generated by the function.
   
   📤 Don’t Miss a Project Again
   
   This set-it-and-forget-it automation provides a quick daily digest of exciting side projects and innovations on Hacker News—without ever needing to refresh your browser. Whether you're an investor looking for promising tools or a software engineer hunting for inspiration, this workflow can help you stay on top of fresh ideas right from your inbox.
   
   The best part? You can enhance the setup even further:
   - Add a Telegram or Slack integration for notifications
   - Store trending posts in Airtable or Google Sheets
   - Expand the logic to include “Ask HN” or other popular categories
   
   🚀 Why Use n8n for This?
   
   n8n (short for "nodemation") is a powerful workflow automation platform that allows you to connect different web services, perform conditional logic, and build data pipelines—all without spinning up a server or writing boilerplate code. It’s open-source and extensible, making it ideal for workflows like these where APIs may not be readily available or you want full control over how and when data is processed.
   
   Ready to put Hacker News in autopilot mode? Try building this workflow in your own n8n instance and see how automation can turn daily data chaos into streamlined productivity.
   
   🔗 Final Thoughts
   
   From scraping and filtering to formatting and emailing, this n8n workflow demonstrates the amazing possibilities of no-code automation. With just a few nodes, you can create your own personal curation engine and never miss another inspiring “Show HN” again.

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.
