Laravel API Versioning

Header-based API versioning with version flags for Laravel. Supports semantic versioning and feature flag-like version control.

Features

• 🏷️ Header-based versioning - Uses X-API-Version header (industry standard like Stripe, GitHub)
• 📦 Semantic versioning - Full support for major.minor.patch format (1.0.0, 1.1.0, 2.0.0)
• 🚩 Version flags - Enable/disable versions independently (perfect for app store review periods)
• 🔒 Minimum version middleware - Require minimum version per route: min.version:1.1.0
• 🔄 Controller inheritance - Override only changed methods in versioned controllers
• 📱 Mobile-friendly - Disabled versions return version_enabled: false so apps can hide features
• 🌍 Translations - Built-in support for English, Japanese, and Korean

Installation

composer require jeromejhipolito/laravel-api-versioning

Publish Configuration (Optional)

php artisan vendor:publish --tag=api-versioning-config
php artisan vendor:publish --tag=api-versioning-lang

Configuration

Add to your .env:

# Optional: Comma-separated list of enabled versions (null = all enabled)
API_ENABLED_VERSIONS=1.0.0,1.1.0

# Optional: Default version when header is missing
API_DEFAULT_VERSION=1.0.0

Edit config/api-versioning.php:

return [
    'supported_versions' => ['1.0.0', '1.1.0', '2.0.0'],
    'enabled_versions' => env('API_ENABLED_VERSIONS') 
        ? array_map('trim', explode(',', env('API_ENABLED_VERSIONS')))
        : null, // null = all supported versions enabled
    'default_version' => env('API_DEFAULT_VERSION', '1.0.0'),
];

Register Middleware

In bootstrap/app.php:

use JeromeJHipolito\ApiVersioning\Middleware\ApiVersionMiddleware;
use JeromeJHipolito\ApiVersioning\Middleware\ResolveVersionedController;

->withMiddleware(function (Middleware $middleware) {
    $middleware->api(append: [
        ApiVersionMiddleware::class,
        ResolveVersionedController::class,
    ]);
})

Usage

Making Requests

# With version header
curl -H "X-API-Version: 1.0.0" https://api.example.com/users

# Without header (uses default version)
curl https://api.example.com/users

Response Headers

Every response includes:

• X-API-Version: 1.0.0
• X-API-Version-Enabled: true
• X-API-Supported-Versions: 1.0.0, 1.1.0, 2.0.0
• X-API-Enabled-Versions: 1.0.0, 1.1.0

Check Version Status

GET /api/version/status

{
  "status": "success",
  "data": {
    "current_version": "1.0.0",
    "version_enabled": true,
    "default_version": "1.0.0",
    "supported_versions": ["1.0.0", "1.1.0", "2.0.0"],
    "enabled_versions": ["1.0.0", "1.1.0"],
    "version_flags": {
      "1.0.0": true,
      "1.1.0": true,
      "2.0.0": false
    }
  }
}

Using in Controllers

use JeromeJHipolito\ApiVersioning\Traits\VersionAwareTrait;

class UserController extends Controller
{
    use VersionAwareTrait;

    public function show($id)
    {
        $user = User::find($id);
        
        // Check version
        if ($this->isVersionAtLeast('2.0.0')) {
            return new V2\UserResource($user);
        }
        
        return new UserResource($user);
    }
}

Using in Resources

use JeromeJHipolito\ApiVersioning\Traits\VersionAwareResourceTrait;

class UserResource extends JsonResource
{
    use VersionAwareResourceTrait;

    public function toArray($request): array
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            
            // Only in 1.1.0+
            ...$this->mergeWhenVersion('1.1.0', [
                'profile_score' => $this->profile_score,
            ]),
            
            // Only below 2.0.0 (deprecated)
            ...$this->mergeWhenVersionBelow('2.0.0', [
                'legacy_field' => $this->old_data,
            ]),
        ];
    }
}

Disabled Version Response

When a version is supported but not enabled:

{
  "status": "success",
  "version_enabled": false,
  "message": "This API version is currently disabled...",
  "current_version": "2.0.0",
  "data": null
}

This allows mobile apps to check version_enabled and hide features accordingly.

Version Flags Workflow

1. Add new version as supported but disabled

   'supported_versions' => ['1.0.0', '2.0.0'],
   

   API_ENABLED_VERSIONS=1.0.0
   

2. Deploy to production - Old apps continue working

3. Submit new app version - App checks version_flags and hides 2.0.0 features

4. After app store approval - Enable the version

   API_ENABLED_VERSIONS=1.0.0,2.0.0
   

Minimum Version Middleware

Require a minimum API version for specific routes or groups:

Register the Middleware Alias

In bootstrap/app.php:

use JeromeJHipolito\ApiVersioning\Middleware\MinimumVersionMiddleware;

->withMiddleware(function (Middleware $middleware) {
    $middleware->alias([
        'min.version' => MinimumVersionMiddleware::class,
    ]);
})

Usage

// Single route
Route::post('new-feature', [FeatureController::class, 'store'])
    ->middleware('min.version:1.1.0');

// Route group
Route::group(['middleware' => ['min.version:2.0.0']], function () {
    Route::post('advanced', [AdvancedController::class, 'store']);
    Route::delete('advanced/{id}', [AdvancedController::class, 'destroy']);
});

Response When Version Is Too Low

{
    "message": "This endpoint requires API version 1.1.0 or higher",
    "current_version": "1.0.0",
    "minimum_version": "1.1.0"
}

HTTP Status: 400 Bad Request
