Core Concepts: Nodes, Workflows, and Triggers

Understanding n8n's core concepts is essential for building effective automations. n8n uses a node-based visual programming model where workflows are composed of connected nodes that process and transform data as it flows through the automation.

Building Your First n8n Workflow

Let's build a practical workflow step-by-step. We'll create a lead enrichment automation that takes new form submissions, enriches them with company data, scores the lead, and routes it to the appropriate sales rep.

Step-by-Step Tutorial: Lead Enrichment Workflow

Back to contents

Step 1: Add a Webhook Trigger

Start by adding a Webhook node to receive form submissions. This creates a unique URL that your form can POST data to.

1. Click the + button to add a new node
2. Search for "Webhook" and select it
3. Set HTTP Method to POST
4. Copy the webhook URL for your form

Step 2: Enrich with Company Data

Add an HTTP Request node to call a data enrichment API (like Clearbit or Apollo) using the lead's email domain.

1. Add an HTTP Request node
2. Set the URL to your enrichment API endpoint
3. Use an expression to pass the email: {{ $json.email }}
4. Configure authentication headers

Step 3: Score the Lead

Use a Code node to calculate a lead score based on company size, industry, and other factors.

// Calculate lead score
const company = $input.first().json;
let score = 0;

// Score based on company size
if (company.employees > 1000) score += 30;
else if (company.employees > 100) score += 20;
else if (company.employees > 10) score += 10;

// Score based on industry
const targetIndustries = ['Technology', 'Finance', 'Healthcare'];
if (targetIndustries.includes(company.industry)) score += 25;

// Score based on funding
if (company.funding > 10000000) score += 20;

return [{ json: { ...company, leadScore: score } }];

Step 4: Route to Sales Rep

Add an IF node to route high-value leads to senior reps and others to the general queue.

1. Add an IF node
2. Set condition: {{ $json.leadScore }} > 50
3. True branch → Senior Sales Rep (Slack/Email)
4. False branch → General Sales Queue (CRM)

Step 5: Add to CRM

Finally, add the enriched lead to your CRM (HubSpot, Salesforce, etc.) with all the gathered data.

1. Add your CRM node (e.g., HubSpot)
2. Select "Create Contact" operation
3. Map all enriched fields to CRM properties
4. Include the lead score as a custom property
