The collection will be saved to: storage/postman/api_collection.json

Configuration Guide

Route Organization

Configure how API routes are organized in Postman folders, how request names are formatted, and how request bodies are generated, including optional default values for fields.

'structure' => [
    'folders' => [
        'strategy' => 'nested_path', // 'prefix', 'nested_path', or 'controller'
        'max_depth' => 3, // Only for nested_path strategy
        'mapping' => [
            'admin' => 'Administration' // Custom folder name mapping
        ]
    ],
  
    'naming_format' => '[{method}] {uri}', // placeholders: {method} {uri} {controller} {action}

    /**
    * Request body settings:
    * - default_body_type: 'raw' or 'formdata'
    * - default_values: preset values applied to generated fields
    */
    'requests' => [
        'default_body_type' => 'raw',
        
        'default_values' => [
            // 'email' => 'test@example.com',
            // 'password' => '123456',
        ],
    ],

]

Route Filtering

Control which routes are included:

'routes' => [
    'prefix' => 'api', // Base API prefix
    
    'include' => [
        'patterns' => ['api/users/*'], // Wildcard patterns
        'middleware' => ['api'], // Only routes with these middleware
        'controllers' => [App\Http\Controllers\UserController::class] // Specific controllers
    ],
    
    'exclude' => [
        'patterns' => ['admin/*'],
        'middleware' => ['debug'],
        'controllers' => [App\Http\Controllers\TestController::class]
    ]
]

Authentication Setup

Document your API authentication:

'auth' => [
    'enabled' => true,
    'type' => 'bearer', // 'bearer', 'basic', or 'api_key'
    'location' => 'header', // 'header' or 'query' for API keys
    
    'default' => [
        'token' => env('POSTMAN_AUTH_TOKEN'),
        'username' => env('POSTMAN_AUTH_USER'),
        'password' => env('POSTMAN_AUTH_PASSWORD'),
        'key_name' => 'X-API-KEY',
        'key_value' => env('POSTMAN_API_KEY')
    ],
    
    'protected_middleware' => ['auth:api', 'auth:sanctum']
]

Output Configuration

'output' => [
        'driver' => env('POSTMAN_STORAGE_DISK', 'local'),

        // Storage path for generated files
        'path' => env('POSTMAN_STORAGE_DIR', storage_path('postman')),

        // File naming pattern (date will be appended)
        'filename' => env('POSTMAN_STORAGE_FILE', 'api_collection'),
    ],

Authentication Examples

Bearer Token

'auth' => [
    'enabled' => true,
    'type' => 'bearer',
    'default' => [
        'token' => 'your-bearer-token'
    ]
]

Basic Auth

'auth' => [
    'enabled' => true,
    'type' => 'basic',
    'default' => [
        'username' => 'api-user',
        'password' => 'secret'
    ]
]

API Key

'auth' => [
    'enabled' => true,
    'type' => 'api_key',
    'location' => 'header', // or 'query'
    'default' => [
        'key_name' => 'X-API-KEY',
        'key_value' => 'your-api-key-123'
    ]
]

Environment Variables

Use .env values for sensitive data:

'auth' => [
    'default' => [
        'token' => env('POSTMAN_DEMO_TOKEN', 'test-token')
    ]
]

Output Example

Generated Postman collection will:

• Group routes by your chosen strategy
• Apply authentication to protected routes
• Include all configured headers
• Use variables for base URL and auth credentials

{
  "info": {
    "name": "My API",
    "description": "API Documentation"
  },
  "variable": [
    {"key": "base_url", "value": "https://api.example.com"},
    {"key": "auth_token", "value": "your-token"}
  ],
  "item": [
    {
      "name": "[GET] users",
      "request": {
        "method": "GET",
        "body": {
          "mode": "raw",
          "raw": "{\"email\":\"user@example.com\",\"password\":\"password123\"}"
        },
        "auth": {
          "type": "bearer",
          "bearer": [{"key": "token", "value": "{{auth_token}}"}]
        }
      }
    }
  ]
}
