Environment Variables

Overview

Environments let you define sets of key-value variables (like base_url, api_token, user_id) and switch between them. Variables are substituted into your requests using {{variable_name}} syntax.

Creating an environment

1. Click the environment selector in the header bar (shows “No Environment” by default)
2. Click Manage Environments
3. Click Create Environment
4. Give it a name (e.g., “Development”, “Staging”, “Production”)
5. Add variables as key-value pairs

Each variable has:

• Key — the variable name (used as {{key}})
• Value — the substituted value
• Enabled — toggle to include/exclude without deleting

Using variables

Use {{variable_name}} anywhere in your requests:

• URL — {{base_url}}/api/users
• Query parameters — Key: token, Value: {{api_token}}
• Headers — Value: Bearer {{access_token}}
• Request body — {"user_id": "{{user_id}}"}
• Auth fields — Bearer token: {{jwt_token}}

Variables are resolved just before the request is sent. Unresolved variables (no matching key in the active environment) are left as-is.

Switching environments

Click the environment selector in the header and choose an environment to activate. Only one environment can be active at a time.

When you switch environments, all {{variable}} references in your requests resolve to the new environment’s values. This makes it easy to test the same requests against different servers or with different credentials.

Managing environments

From the Manage Environments modal you can:

• Edit variables in any environment
• Delete an environment
• Activate/deactivate an environment
• Toggle individual variables on/off

Example setup

Variable	Development	Production
base_url	http://localhost:3000	https://api.example.com
api_token	dev-token-123	prod-token-456
timeout	5000	30000
