Overview

Variables store reusable non-secret values.

​
Using variables in expressions

Access a variable in expressions with:

​
Variable fields

Each variable has these fields:
  • Name: a lowercase snake case name such as jira or api_config
  • Values: one or more key-value pairs
  • Environment: the Workflow environment where the variable applies

​
When to use variables

Use variables for non-sensitive values such as:
  • Base URLs
  • Project IDs
  • Queue names
  • Routing rules
  • Tenant-specific defaults
Use a secret for sensitive values.

​
Variable environments

Every variable belongs to a Workflow environment.
  • Default source: the workflow default environment in Workflows.
  • Override: per action in Actions control flow.
  • Fallback: default.

​
Access variables in agents

Agents can use variable expressions in tool arguments and integration configuration. Values are resolved during tool execution and are not fetched directly by the LLM provider.
  • See Secrets for sensitive values such as API keys, passwords, and certificates.
  • See Expressions for how expressions work across triggers, actions, secrets, and variables.
