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

   Automatically Identify High-Value Community Signups Using n8n and Clearbit
   
   Growing an online community is exciting—but knowing which new members might be valuable leads for your business is even better. Instead of manually checking each signup, you can automate this entire process using n8n, a powerful workflow automation tool.
   
   In this guide, we’ll walk through an n8n workflow that enriches new Discourse user signups with Clearbit, evaluates them based on company size and web presence, and instantly alerts your team in Slack when someone "high value" joins.
   
   Let’s explore how this works, step by step.
   
   Step 1: Trigger Workflow on New User Signup in Discourse
   
   The workflow begins with the On new Discourse user node, which acts as a webhook waiting for POST requests from the Discourse platform whenever a new signup occurs. To activate this trigger, configure a webhook in your Discourse admin dashboard and point it to the n8n webhook path. (Need help? Watch the Loom video embedded in the sticky note in the workflow.)
   
   Step 2: Filter Out Common Personal Email Addresses
   
   Next, the Filter out common personal emails node checks the user email to exclude common free email providers like Gmail, Yahoo, Hotmail, and ProtonMail. Why? Because personal emails are rarely tied to professional opportunities and enriching them wastes Clearbit API credits.
   
   The workflow uses a simple logic: if the email does NOT contain any of the blocked domains, it is passed forward. Otherwise, it stops there, saving time and API usage.
   
   Step 3: Enrich User Data with Clearbit
   
   The Enrich user with Clearbit node takes the validated email and calls Clearbit’s “person” API to gather detailed insights like name, company, job title, social media handles, and avatar.
   
   If Clearbit can't find the email (typically returning a 404), the workflow safely continues with No clearbit enrichment available. A sticky note nearby suggests sending a manual Slack message or exploring other enrichment services for missing profiles.
   
   Step 4: Retrieve Company Data
   
   If enrichment is successful, the workflow uses the employment.domain property retrieved from Clearbit to call the Get company info node—another Clearbit API call. This fetches additional data such as number of employees, Alexa global rank, and industry.
   
   These metrics are crucial for scoring the lead’s business impact.
   
   Step 5: Filter for High-Value Leads
   
   With both person and company data enriched, the Filter for high value leads node applies conditional logic:
   
   - The user's company must have at least 30 employees.
   - Its Alexa global rank must be under 100,000 (indicating strong web traffic).
   
   These two criteria define what is considered "high value" in this template. A sticky note prompts users to customize these filters based on specific business needs.
   
   Step 6: Notify Slack Channel
   
   Not all leads are created equal—which is why the Post message in Channel node is used here to send detailed lead alerts to your preferred Slack channel (#team-design by default). The Slack message contains:
   
   - User’s full name, job title, and company
   - Company industry
   - Profile avatar
   - Action buttons to open their LinkedIn or email them directly
   
   This notification helps sales or community teams prioritize follow-ups on promising signups in real-time.

   - Sticky Note 1: Offers guidance if no Clearbit enrichment is available.
   - Sticky Note 3: Links to setup videos and provides context for configuring Discourse webhooks.
   - Sticky Note 4: Instructs how to update the Slack channel name to fit your team’s structure.
   
   Why This Workflow Matters
   
   This elegant use of n8n helps bridge your community-building efforts with your sales and marketing pipeline. By automatically qualifying and surfacing promising leads, your team can act faster and smarter—without sifting through every signup manually.
   
   And thanks to n8n’s visual, no-code platform, you don’t need to write any server-side logic. Everything is drag-and-drop configurable with room for customization (e.g., adding CRM integration or sending emails).
   
   Conclusion
   
   With a few API connections and clever filters, you can turn your Discourse forum into a self-qualifying lead funnel. The workflow above offers a ready-to-use foundation for identifying high-potential users and routing them to your team in real-time.
   
   As your community grows, so can your lead intelligence—automatically.

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.
