Environments

Environments let you define variables that are resolved in URLs, headers, and body content. Use them to switch between dev, staging, and production configurations instantly.

How Variables Work

Variables use {{variable_name}} syntax. When a request is sent, Flamingo replaces all {{variable_name}} occurrences with values from the active environment.

Global Environment

Flamingo includes a Globals environment that is always available. Use it for values that do not change between environments.

Creating Environments

1. Open the sidebar and click the Environments panel (beaker icon)
2. Click New Environment
3. Type a name and press Enter
4. Add variables using the key-value editor

Variable Editor

Each environment shows its variables in an editable list:

Variable	Value
base_url	api.example.com
api_key	sk-abc123
token	jwt-token-here

Toggle the environment’s checkbox to activate it. Only one environment can be active at a time (plus Globals).

Switching Environments

Select an environment from the dropdown in the title bar. The active environment’s color indicator appears next to its name.

Example

// Environment: Development
//   base_url = dev-api.example.com
//   api_key  = dev-key-123

// Environment: Production
//   base_url = api.example.com
//   api_key  = prod-key-456

// Request URL: https://{{base_url}}/users
// Header: X-API-Key: {{api_key}}

// With Development active:
//   URL:    https://dev-api.example.com/users
//   Header: X-API-Key: dev-key-123

// With Production active:
//   URL:    https://api.example.com/users
//   Header: X-API-Key: prod-key-456

Variable Resolution

Variables are resolved in:

• URL
• Query parameters (key and value)
• Headers (key and value)
• Body content (JSON, XML, text, form-data, URL-encoded)
• Authentication fields
