Using Variables

Pass data between nodes using variables

What are variables?

Variables are placeholders that let you pass data dynamically between nodes. Instead of hardcoding values, you reference outputs from other nodes.

Static:  url = "https://example.com"
Dynamic: url = {{url}}

With variables, your workflows become flexible and reusable.

Variable syntax

Basic syntax

Variables use double curly braces:

{{var}}

Part	Description
{{ }}	Variable delimiters
NodeName	The name of the variable

Accessing node outputs

Simple outputs

For nodes with a single output:

{{var}}

Structured outputs

For nodes that return objects, use dot notation:

// Web Scraper output
{
  "content": "Page text...",
  "title": "Page Title",
  "metadata": {
    "url": "https://example.com",
    "wordCount": 1500
  }
}

Array outputs

For arrays, use index notation:

// Google Sheets output
{
  "rows": [
    {"name": "Alice", "email": "alice@example.com"},
    {"name": "Bob", "email": "bob@example.com"}
  ]
}

Access array items:

{{$.rows[0].name}}  → "Alice"
{{$.rows[1].email}} → "bob@example.com"

Using variables in nodes

In text fields

Embed variables directly in text:

Summarize this article about {{topic}}:

{{WebScraper_0}}

Focus on: {{keywords}}

In URL fields

Build dynamic URLs:

https://api.example.com/search?q={{query}}&page={{page_number}}

In JSON fields

Use variables in JSON configuration:

{
  "title": "{{article_title}}",
  "content": "{{LLM_0}}",
  "author": "{{author_name}}"
}
