Environment variables let you store sensitive values (API keys, tokens, configuration strings) outside of your workflow definitions. Reference them in any node without hardcoding secrets.

​
Creating an Environment Variable

1

Go to Settings

Navigate to Settings → Environment Variables.
2

Add a variable

Click New Variable. Enter a name and value.
3

Use in workflows

Reference the variable in any node configuration field.

​
Naming Rules

Environment variable names must:
  • Start with an uppercase letter
  • Contain only uppercase letters, numbers, and underscores
  • Be at most 100 characters
Examples: API_KEY, SLACK_TOKEN, DATABASE_URL

​
Security

  • Values are encrypted at rest and never displayed in plain text after creation
  • When editing a variable, you must re enter the value (the current value is not shown)
  • Variables are scoped to your workspace and not shared across workspaces

​
Using in Workflows

Environment variables are available through the variable picker in any node configuration field. Select from the environment variables section to inject the value at runtime.
