Master Liquid Templating Fundamentals

Liquid templating provides powerful yet simple syntax for dynamic workflow automation. These three core concepts enable sophisticated data handling and conditional logic in your workflows. What you’ll learn:
  • Access workflow data with object notation
  • Create conditional content with tags
  • Transform data using filters
  • Combine all three for complex logic
1

Objects: Access Workflow Data

Objects retrieve and display data from previous workflow steps using double curly brace syntax.

​
How to Access Workflow Data

Use dot notation to navigate through workflow data structures. When a previous workflow step (like node_1) produces structured data, access nested properties with dots.
Hello, {{ node_1.user.name }}!

​
How to Access Array Elements in Workflows

Access specific array items using square bracket notation with zero-based indexing. Essential for processing API responses and list data.
First product is: {{ node_1.products[0] }}
If you try to access a variable that doesn’t exist, Liquid will simply output nothing. It will not cause your workflow to fail.

Tags: Control Workflow Logic

Tags provide conditional logic and control flow without generating output. Use tags to create smart, responsive workflow content that adapts to your data.

​
Conditional Content Example

Create personalized workflow responses using conditional tags:
{% if node_1.user.name == "Alice" %}
  Welcome, Alice!
{% endif %}
We cover all the powerful logic tags like if, for, and case in detail on the Logic and Control Flow Tags page.

Filters: Transform Workflow Data

Filters modify object output using pipe notation. Transform data formats, apply calculations, and format content within workflow steps.

​
Basic Filter Example

Transform workflow data with simple filters like text formatting:
Hello, {{ node_1.user.name | upcase }}!

​
How to Chain Multiple Filters

Combine multiple filters for complex data transformations, processing from left to right:
{{ "welcome to the jungle" | capitalize | truncate: 15 }}
Filters can take arguments, like 15 in the truncate example above. Explore all the possibilities on the Working with Filters page.
