# n8n IF Node: A Complete Guide for South African Automation Professionals

## Introduction

The **n8n IF node** has become an essential tool for South African businesses automating their workflows without requiring extensive coding knowledge. As workflow automation continues to gain momentum in 2025, understanding conditional logic is critical for anyone building intelligent automation systems. The **n8n IF node** enables you to create branching workflows that make decisions based on specific conditions, routing data down different paths depending on whether criteria are true or false.[1][4]

Whether you're managing customer data, processing expense reports, or automating email sequences, the **n8n IF node** gives you the power to build dynamic, responsive workflows that adapt to your business needs. This guide walks you through everything you need to know about using the **n8n IF node** effectively.

## Understanding the n8n IF Node Basics

The **n8n IF node** functions as a conditional router in your workflow automation platform. At its core, it evaluates conditions and splits your workflow into two branches: one for true conditions and another for false conditions.[2] This branching capability is what makes the **n8n IF node** so powerful for creating intelligent automation sequences.

How the n8n IF Node Works

When data flows into the **n8n IF node**, it evaluates your specified conditions. If the condition evaluates to true, the data routes through the true branch. If it evaluates to false, the data routes through the false branch.[1] This simple yet powerful mechanism allows you to control workflow execution paths automatically.

Think of the **n8n IF node** as a decision point in your automation. For example, if you're processing expense reports, the **n8n IF node** could check whether an expense exceeds a certain amount. If true, it might route the expense for approval. If false, it might automatically categorize it as pre-approved.

Key Features of the n8n IF Node

The **n8n IF node** supports multiple comparison operations across different data types:

- **String comparisons**: equals, contains, starts with, ends with - **Numeric comparisons**: greater than, less than, equal to - **Date and time comparisons**: is after, is before, is between - **Boolean evaluations**: true/false logic - **Array and object operations**: exists, does not exist, is empty, is not empty[3]

This versatility makes the **n8n IF node** suitable for virtually any conditional logic scenario.

## Practical Applications of the n8n IF Node

Building Dynamic Email Sequences

One of the most common uses for the **n8n IF node** is automating email sequences. Imagine you want to send different emails based on customer behavior. The **n8n IF node** can check whether a customer opened a previous email and route them to different follow-up sequences accordingly.[4]

Expense Management and Filtering

The **n8n IF node** excels at filtering data based on multiple criteria. For instance, you could use the **n8n IF node** to process expense data by checking:

- Whether the expense category is "groceries" or "meals" - Whether the amount exceeds a specific threshold - Whether the date falls within a particular period

By combining multiple conditions with AND logic, the **n8n IF node** creates sophisticated filtering rules without requiring code.[1]

Data Routing and Processing

The **n8n IF node** is instrumental in routing data to different destinations. For example:

- If an order value exceeds R5,000, route it to a premium fulfillment service - If a customer has been inactive for 90 days, route them to a re-engagement campaign - If a support ticket contains certain keywords, route it to the appropriate department

## Creating Conditions in the n8n IF Node

Adding Your First Condition

To add a condition to the **n8n IF node**:

1. Select the data type from the dropdown (String, Number, Date & Time, Boolean, Array, or Object) 2. Choose your comparison operation (equals, contains, greater than, etc.) 3. Enter the value to compare against 4. Click "Add condition" to create additional conditions

The **n8n IF node** allows you to build complex logic by adding multiple conditions. These conditions can be combined using AND logic, meaning all conditions must be true for the true branch to execute.[2]

Working with Different Data Types

The **n8n IF node** adapts its input fields based on your selected data type. For date comparisons, you'll see date picker fields. For string comparisons, you'll see text input fields. This context-aware interface makes the **n8n IF node** intuitive to use regardless of your data type.

## Advanced n8n IF Node Techniques

Nested IF Nodes

For complex decision trees, you can nest multiple **n8n IF node** instances within your workflow. This allows you to create multi-level conditional logic. For example, your first **n8n IF node** might check if an amount exceeds R1,000, and if true, a second **n8n IF node** checks the category type.[3]

Combining the n8n IF Node with Other Nodes

The **n8n IF node** works seamlessly with other n8n nodes:

- **Merge node**: Combine outputs from both true and false branches - **Switch node**: Handle more than two conditions (alternative to multiple IF nodes) - **Code node**: Perform complex custom logic before or after the **n8n IF node**

Important consideration: If you add a Merge node after the **n8n IF node**, be aware that both output data streams may execute, even if one branch produces no data. This can affect your workflow behavior.[2]

## Best Practices for Using the n8n IF Node

Keep Conditions Simple and Readable

While the **n8n IF node** supports complex logic, simpler conditions are easier to maintain and debug. If your logic becomes too complex, consider using multiple **n8n IF node** instances instead of combining too many conditions.

Test Your Conditions Thoroughly

Before deploying workflows using the **n8n IF node**, test with various data scenarios. Test edge cases, boundary values, and unexpected data formats to ensure your **n8n IF node** behaves as expected.

Use Meaningful Node Names

Label your **n8n IF node** instances with descriptive names that indicate what condition they're checking. This makes your workflow easier to understand and maintain.

Document Your Logic

Add notes to your workflow explaining the purpose of each **n8n IF node** and what conditions trigger each branch. This documentation is invaluable when returning to workflows months later.

## Real-World Example: Expense Approval Workflow

Here's a practical workflow structure using the **n8n IF node**:

Manual Trigger ↓ Airtable (Fetch Expenses) ↓ n8n IF Node (Check: Amount > R5,000 AND Category = "Travel") ├─ TRUE → Send for Manager Approval └─ FALSE → Auto-Approve & Write to Spreadsheet

This workflow demonstrates how the **n8n IF node** can automate approval processes by routing expenses based on predefined criteria.

## Troubleshooting Common n8n IF Node Issues

**Condition not evaluating as expected**: Verify your data types match. String comparisons are case-sensitive by default in the **n8n IF node**.

**Both branches executing**: If you're using a Merge node downstream, this is expected behavior. The **n8n IF node** may trigger both branches.

**Missing data in output**: Ensure your **n8n IF node** condition is correctly configured and that your comparison values are accurate.
