If / Else Node

The If / Else node is used to make decisions in a workflow.
It checks a condition and then sends the flow to the correct path based on the result.

How the Node Works

1. The node checks the If condition first
2. If it is true, that path runs and the rest are skipped
3. If it is false, it checks the Else If conditions
4. If none match, the Else path runs

Only one path can run at a time.

Main Fields Explained

Condition Label

• A readable name for the condition
• Helps you understand the logic visually
• Does not affect execution

Example:

Satisfied User

Expression (Using CEL)

We are using CEL in Expression

In the Expression field, we use Common Expression Language (CEL) to write conditions.

CEL is used to define logic that decides which path the workflow should take.

What is CEL?

Common Expression Language (CEL) is a simple, fast, and safe expression language used to evaluate conditions.

• Similar to common programming languages
• Used for decision-making, filtering, and validation
• Works well with structured data like JSON or previous node outputs

CEL Examples

previous_output == "yes"
 
If the value is "yes", the condition evaluates to true.
 

user.age > 18
 
Checks if the user's age is greater than 18.
 

Advanced Example
previous_output == "no" || user.plan == "free"
 
Condition is true if:
 
user selected "no" OR user is on "free" plan

Question: Was this answer helpful?

If → previous_output == “yes” → Show thank-you message

Else If → previous_output == “no” → Route to live chat

Else → End workflow

Best Practices

• Always add an Else path
• Keep expressions simple and readable
• Match expressions with exact option values
• Use labels to clearly describe the logic

Summary

The If / Else node allows your workflow to:

• React to user choices
• Handle multiple scenarios
• Control execution flow safely and clearly
