Variables

Variables let you use data from the trigger or previous steps anywhere in your workflow.

Basic Syntax

Variables are wrapped in double curly braces:

{{source.field}}

From the Trigger

{{trigger.customer_name}}
{{trigger.order_id}}
{{trigger.email}}

From Previous Steps

{{steps.extract_invoice.total}}
{{steps.api_call.response.status}}
{{steps.validate.is_valid}}

Using the Variable Picker

Instead of typing variables manually:

1. Click in any field that accepts variables
2. Type {{ to open the picker
3. Browse available data
4. Click to insert

The picker shows you everything available from the trigger and completed steps.

Accessing Nested Data

Object Properties

Use dots to navigate into objects:

{{trigger.customer.address.city}}
{{steps.response.data.user.email}}

Array Items

Use brackets with an index (starting at 0):

{{trigger.items[0]}}
{{trigger.items[0].name}}
{{steps.extract.line_items[2].price}}

Data Types

Variables can contain different types of data:

Common Uses

Dynamic URLs:

https://api.example.com/orders/{{trigger.order_id}}

Message content:

Order {{trigger.order_id}} from {{trigger.customer.name}} is ready.

Template fields:

Customer: {{steps.extract.customer_name}}
Total: {{steps.extract.total}}

Tips

Name steps clearly {{steps.extract_invoice.total}} beats {{steps.action_3.field_2}}

Use the picker Don't guess at field names

Check types Don't put quotes around numbers, use array syntax for lists

When Variables Aren't Enough

If you need to transform data, do math, or make comparisons, switch the field to dynamic mode and use Expressions.

• Expressions — Transform and compare data
• Actions — Configure workflow steps
