​
Template Variables

Variables allow you to pass data dynamically between nodes using the {{variable}} syntax.

​
Basic Syntax

Reference a variable by wrapping its path in double curly braces: 
{{nodeName.output.fieldName}}

​
Examples

​
Accessing Node Output

If you have a node named ai_generate that outputs text: 
{{ai_generate.output.text}}

​
Accessing Trigger Data

For webhook triggers with JSON payload: 
{{trigger.body.email}}
{{trigger.body.name}}

​
Nested Objects

Access nested properties with dot notation: 
{{airtable.output.record.fields.Name}}
{{slack.output.message.ts}}

​
Variable Picker

The editor includes a variable picker that shows available variables from previous nodes. Click the { } button in any text field to open it.

​
Type Coercion

Variables are automatically converted to strings when used in text fields. For nodes expecting specific types (numbers, arrays), the value is passed as-is.

​
Best Practices

  • Use descriptive node names - Makes variables easier to understand
  • Check for existence - Some outputs may be undefined
  • Keep paths simple - Extract nested data in intermediate nodes if needed
