D: The If node in n8n is your digital decision-maker 🤖, a powerful tool that brings conditional logic to your automations. Let’s dive deep into this game-changing node with practical examples you can implement today!
🔍 What Exactly is an If Node?
The If node evaluates conditions and routes your workflow based on true/false outcomes. Think of it as the “brain” 🧠 that makes your automation smart by adding decision-making capabilities.
// Basic If node structure
{
"conditions": {
"operation": "equal",
"value1": "{{$node["PreviousNode"].json["key"]}}",
"value2": "desiredValue"
}
}
⚙️ How If Node Works: Core Mechanics
- Input Evaluation: Analyzes incoming data
- Condition Checking: Compares values using operators (equals, contains, etc.)
- Path Routing: Sends data to different branches based on results
🌟 10 Powerful Real-World Examples
1. Email Filter System 📧
IF (Email.subject contains "URGENT") → Send to Manager
ELSE IF (Email.sender = "accounting@") → Forward to Finance Dept
ELSE → Archive
2. E-commerce Order Router 🛒
IF (Order.total > $500) → Flag for manual review
ELSE IF (Order.country = "International") → Route to Int'l shipping
ELSE → Process automatically
3. Social Media Moderator 🤖
IF (Post.text contains [bad words list]) → Send to quarantine
ELSE IF (Post.image = NSFW) → Notify admin
ELSE → Publish immediately
4. CRM Lead Qualifier 📈
IF (Lead.score > 75) → Assign to top sales rep
ELSE IF (Lead.company = "Fortune 500") → Route to enterprise team
ELSE → Add to nurture campaign
5. IoT Temperature Alert 🌡️
IF (Sensor.temp > 30°C) → Trigger AC + Send alert
ELSE IF (Sensor.temp 48h) → Escalate to supervisor
ELSE → Add to normal queue
7. Content Publishing Gateway 🖋️
IF (Post.author = "Editor") → Publish immediately
ELSE IF (Post.length > 2000 words) → Send for review
ELSE → Return for editing
8. Inventory Management 📦
IF (Stock.level < reorder_point) → Generate PO
ELSE IF (Stock.expiry 50}}

Add Default Paths: Always include an “ELSE” route for unhandled cases
-
Test Thoroughly: Use the “Test Step” feature to verify all possible outcomes
🚀 Advanced Techniques
- Nested If Nodes: Create decision trees by chaining multiple If nodes
- Data Transformation: Combine with Function nodes for pre-processing
- Error Handling: Route errors to specific troubleshooting paths
📊 Debugging Common Issues
-
Data Not Routing Correctly?
- Check your condition syntax
- Verify data types (string vs number)
- Use console.log equivalent:
{{$json}}
-
Conditions Too Complex?
- Break into multiple If nodes
- Consider using a Function node for logic
🔮 Future of Conditional Workflows
The If node is evolving with:
- AI-powered condition suggestions 🤖
- Visual condition builders 🎨
- Real-time debugging tools 🔍
� Final Thoughts
Mastering the If node transforms your automations from linear scripts to intelligent systems. Start with simple conditions and gradually build complexity as you gain confidence. Remember – every great automation begins with a single “if”!
