The digital landscape is a fierce battleground, and for businesses, a compelling online presence is non-negotiable. When onboarding new clients, especially those with established brands, the ability to quickly generate a functional, on-brand landing page draft can be a significant differentiator. This isn't just about aesthetics; it's about demonstrating immediate value and accelerating the design and development cycle. Imagine a scenario where, within minutes of a client agreeing to a project, you can present them with a landing page draft that already speaks their brand's language – their colors, fonts, and even their tone of voice. This is precisely the power of leveraging AI-driven brand extraction. In this tutorial, we'll dive deep into building a robust Native PHP 8.3+ integration that utilizes the Brand Kit Extractor API to achieve just that, creating a safe, production-ready landing page theme draft from any public website during the onboarding process.

Unlocking Your Client's Brand DNA

The core challenge in creating tailored digital experiences lies in understanding the client's existing brand identity. Manually dissecting a website to identify color palettes, typography, logo variations, and social media links is time-consuming and prone to human error. The Mihajlo AI Brand Kit Extractor API automates this tedious process, providing a structured, evidence-based representation of a website's visual identity. This extracted data serves as an invaluable blueprint for rapid theme generation.

Why This Matters for Production Integrations

For senior developers and technical leads, the focus isn't just on making an API call; it's about building a resilient, secure, and maintainable integration. This involves careful consideration of:

API Contract Adherence: Understanding and precisely implementing the API's request and response structures.
Authentication and Security: Securely managing API credentials and protecting sensitive data.
Error Handling and Resilience: Designing for network issues, API rate limits, and unexpected responses.
Data Validation and Sanitization: Ensuring the integrity of the extracted brand data before it's used.
Architecture and Modularity: Structuring the code for testability and future enhancements.
Observability: Implementing logging and monitoring for proactive issue detection.

This tutorial will guide you through building an integration that addresses these critical production concerns within a Native PHP 8.3+ application.

Getting Access to the Brand Kit Extractor API

Before we can integrate the API into our PHP application, we need to obtain the necessary credentials. The process is straightforward and designed for quick developer access.

Step-by-Step Onboarding

Registration or Sign-In: Navigate to https://ai.mihajlo.mk/register to create a new account or visit https://ai.mihajlo.mk/login to log in if you already have one.
API Service Selection: Once logged in, go to the Brand Kit Extractor API service page. Here, you can choose a plan that suits your needs – Free, Plus, or Pro – and activate it.
Token Retrieval: After activating your chosen plan, proceed to the official service documentation. In the "Service token" panel, you will find your unique service-scoped token.

Important Note on Token Regeneration: Be aware that regenerating your service token will revoke any previously active tokens. Ensure you securely store the current, active token and do not regenerate it unless absolutely necessary.

Once you have your service token, the next step is to securely store it within your PHP project's environment configuration. This prevents hardcoding sensitive credentials directly into your codebase, a crucial security practice.

Project Architecture and Setup

For this integration, we'll adopt a clean architecture that isolates the API interaction into a dedicated service class. This promotes separation of concerns, making the code more maintainable and testable. We'll use native PHP features and a standard HTTP client to ensure broad compatibility and avoid unnecessary dependencies.

Environment Configuration

We'll leverage the ubiquitous .env file for storing our API token. Ensure you have a package installed that handles loading these variables (e.g., vlucas/phpdotenv is common, or frameworks like Laravel handle this out-of-the-box). Add the following line to your .env file:

MIHAJLO_API_TOKEN=YOUR_SERVICE_TOKEN

Replace YOUR_SERVICE_TOKEN with the actual token obtained from the Mihajlo AI platform. This placeholder serves as a reminder to inject the real value during deployment.

HTTP Client and Service Class

We'll create a dedicated BrandKitExtractorService class to encapsulate all interactions with the Brand Kit Extractor API. For making HTTP requests, we'll use PHP's built-in cURL functions for maximum compatibility in a native PHP context, or a PSR-18 compliant HTTP client if preferred and available. For this example, we'll demonstrate using cURL.

src/Services/BrandKitExtractorService.php

namespace App\Services;

use Exception;

class BrandKitExtractorService
{
    private string $apiEndpoint = 'https://ai.mihajlo.mk/api/brand-kit-extractor/v1/extract-brand-kit';
    private string $apiKey;
    private int $connectionTimeout = 10; // seconds
    private int $responseTimeout = 30; // seconds

    public function __construct(string $apiKey)
    {
        if (empty($apiKey)) {
            throw new \InvalidArgumentException('API key cannot be empty.');
        }
        $this->apiKey = $apiKey;
    }

    public function extract(string $websiteUrl): array
    {
        if (empty($websiteUrl)) {

        $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        $curlError = curl_error($ch);
        curl_close($ch);

        if ($response === false) {
            throw new \RuntimeException(sprintf('cURL Error: %s', $curlError));
        }

        if ($httpCode >= 400) {
            // Attempt to parse error response if available
            $errorBody = json_decode($response, true);
            $errorMessage = $errorBody['message'] ?? 'Unknown API error';
            throw new \RuntimeException(sprintf('API Error: HTTP %d - %s', $httpCode, $errorMessage));
        }

        $data = json_decode($response, true);
        if (json_last_error() !== JSON_ERROR_NONE) {
            throw new \RuntimeException('Failed to decode API response: ' . json_last_error_msg());
        }

        return $this->validateAndMapResponse($data);
    }

    private function validateAndMapResponse(array $data): array
    {
        // Validate essential fields. This is a crucial step for production integrity.
        if (!isset($data['brand_name']) || !is_string($data['brand_name'])) {
            throw new \RuntimeException('Invalid API response: Missing or invalid "brand_name".');
        }

        }
        if (!isset($data['fonts']) || !is_array($data['fonts'])) {
            throw new \RuntimeException('Invalid API response: Missing or invalid "fonts".');
        }
        if (!isset($data['imagery']) || !is_array($data['imagery'])) {

        if (!isset($data['css_variables']) || !is_array($data['css_variables'])) {
            throw new \RuntimeException('Invalid API response: Missing or invalid "css_variables".');
        }

        // Perform deeper validation as needed. For example, check URL formats for social profiles.
        // For this example, we'll assume the structure is largely correct if the keys exist and are arrays.

        return $data; // Return the validated and mapped data
    }
}

Dependency Injection

In a real application, you would typically inject the API key into the service using a dependency injection container. For a native PHP setup without a framework, you might instantiate it directly, passing the environment variable:

Example Usage (e.g., in a controller or script)

// Load environment variables (if not using a framework that does this automatically)
$dotenv = Dotenv\Dotenv::createImmutable(__DIR__ . '/../');
$dotenv->load();

$apiKey = $_ENV['MIHAJLO_API_TOKEN'] ?? null;

if (!$apiKey) {
    die("Error: MIHAJLO_API_TOKEN is not set in the environment.");
}

$extractorService = new App\Services\BrandKitExtractorService($apiKey);

try {
    $websiteUrl = 'https://example.com'; // The client's website URL
    $brandKitData = $extractorService->extract($websiteUrl);

    // Now $brandKitData contains the extracted brand information
    // You would then use this data to generate a landing page theme draft.
    print_r($brandKitData);

} catch (\Exception $e) {
    // Log the error appropriately in a production environment
    error_log("Brand Kit Extraction Failed: " . $e->getMessage());
    // Handle the error gracefully for the user
    echo "Could not extract brand information. Please try again later.";
}

Implementing the Landing Page Draft Generation

The extracted brand kit data is the foundation for creating a landing page theme draft. This typically involves:

Storing the Data: Persisting the extracted brand information in your application's database.
Generating Theme Assets: Creating CSS files, potentially JavaScript, and even basic HTML structures that incorporate the brand's colors, fonts, and logo.

Database Schema Considerations

When storing the extracted brand kit, a flexible schema is beneficial. You might have a brand_kits table with columns for:

id
client_id (if linked to a specific client)
website_url
brand_name
logos (JSON or TEXT type to store an array of logo URLs and types)
colors (JSON or TEXT type for an array of color hex codes or definitions)
fonts (JSON or TEXT type for font names, weights, etc.)
social_profiles (JSON or TEXT type)
css_variables (JSON or TEXT type)
created_at
updated_at

Generating a Basic Theme Draft

The goal here is to produce a draft. This means generating a sensible set of default styles and structures that can be further refined by a designer or front-end developer. We can leverage the css_variables provided by the API, as they are often designed for direct CSS integration.

Let's imagine a controller or a command that orchestrates this. For simplicity, we'll show a conceptual controller action that might be triggered during an onboarding workflow.

src/Controllers/OnboardingController.php (Conceptual)

namespace App\Controllers;

use App\Services\BrandKitExtractorService;
use App\Services\ThemeDraftGeneratorService; // A hypothetical service
use App\Models\BrandKit; // Your ORM model

class OnboardingController
{
    private BrandKitExtractorService $extractorService;
    private ThemeDraftGeneratorService $themeGeneratorService;

    public function __construct(BrandKitExtractorService $extractorService, ThemeDraftGeneratorService $themeGeneratorService)
    {
        $this->extractorService = $extractorService;
        $this->themeGeneratorService = $themeGeneratorService;
    }

    public function createLandingPageDraft(string $clientWebsiteUrl, int $clientId): array
    {
        try {
            // 1. Extract Brand Kit
            $brandKitData = $this->extractorService->extract($clientWebsiteUrl);

            // 2. Store Brand Kit Data
            $brandKit = new BrandKit();
            $brandKit->client_id = $clientId;
            $brandKit->website_url = $clientWebsiteUrl;
            $brandKit->brand_name = $brandKitData['brand_name'];
            $brandKit->logos = json_encode($brandKitData['logos']);
            $brandKit->colors = json_encode($brandKitData['colors']);
            $brandKit->fonts = json_encode($brandKitData['fonts']);
            $brandKit->social_profiles = json_encode($brandKitData['social_profiles']);
            $brandKit->css_variables = json_encode($brandKitData['css_variables']);
            $brandKit->save(); // Assuming Eloquent or similar ORM

            // 3. Generate Theme Draft
            // This service would take the brand kit data and generate CSS, basic HTML templates, etc.
            $themeDraftPath = $this->themeGeneratorService->generate($brandKit);

            return [
                'success' => true,
                'message' => 'Landing page theme draft created successfully.',
                'brand_kit_id' => $brandKit->id,
                'theme_path' => $themeDraftPath,
            ];

        } catch (\Exception $e) {
            // Log the error
            error_log("Onboarding draft creation failed for {$clientWebsiteUrl}: " . $e->getMessage());
            // Return an error response
            return [
                'success' => false,
                'message' => 'Failed to create landing page draft. Please check the URL and try again.',
                'error' => $e->getMessage(),
            ];
        }
    }
}

The ThemeDraftGeneratorService would be responsible for taking the structured brand data and outputting files. For example, it could generate a CSS file using the css_variables:

src/Services/ThemeDraftGeneratorService.php (Conceptual)

namespace App\Services;

use App\Models\BrandKit; // Assuming this model holds the JSON data

class ThemeDraftGeneratorService
{
    private string $draftsDirectory = __DIR__ . '/../../storage/theme_drafts/';

    public function __construct()
    {
        if (!is_dir($this->draftsDirectory)) {
            mkdir($this->draftsDirectory, 0777, true);
        }
    }

    public function generate(BrandKit $brandKit): string
    {
        $cssContent = $this->generateCss($brandKit);
        $filename = 'theme_draft_' . $brandKit->id . '_' . date('Ymd_His') . '.css';
        $filePath = $this->draftsDirectory . $filename;

        if (file_put_contents($filePath, $cssContent) === false) {
            throw new \RuntimeException("Failed to write theme draft CSS to {$filePath}");
        }

        // In a real scenario, you might also generate HTML templates or other assets.
        return '/storage/theme_drafts/' . $filename; // Relative path for web access
    }

    private function generateCss(BrandKit $brandKit): string
    {
        $css = "/* Theme Draft for " . htmlspecialchars($brandKit->brand_name) . " */\n\n";

        // Use CSS variables if available and structured
        $cssVariables = json_decode($brandKit->css_variables, true);
        if (is_array($cssVariables)) {
            $css .= ":root {\n";
            foreach ($cssVariables as $name => $value) {
                // Basic sanitization for CSS variable values
                $sanitizedValue = preg_replace('/[^a-zA-Z0-9#.,()%-]/', '', $value);
                $css .= sprintf("  --%s: %s;\n", $name, $sanitizedValue);
            }
            $css .= "}\n\n";
        }

        // Apply primary colors to common elements
        $colors = json_decode($brandKit->colors, true);
        if (is_array($colors) && !empty($colors)) {
            $primaryColor = $colors[0] ?? '#007bff'; // Default if first color is missing
            $css .= "body {\n";
            $css .= sprintf("  background-color: var(--primary-background, #ffffff);\n"); // Fallback
            $css .= sprintf("  color: var(--primary-text, #333333);\n"); // Fallback
            $css .= "}\n\n";
            $css .= "a {\n";
            $css .= sprintf("  color: var(--primary-link-color, %s);\n", $primaryColor);
            $css .= "}\n\n";
            // Add more rules for buttons, headings, etc. using extracted colors or CSS variables.
        }

        // Basic font application
        $fonts = json_decode($brandKit->fonts, true);
        if (is_array($fonts) && !empty($fonts)) {
            $primaryFont = $fonts[0]['name'] ?? 'Arial, sans-serif'; // Basic extraction
            $css .= "body {\n";
            $css .= sprintf("  font-family: var(--primary-font, %s);\n", $primaryFont);
            $css .= "}\n\n";
        }

        // Add a placeholder for the logo
        $logos = json_decode($brandKit->logos, true);
        if (is_array($logos) && !empty($logos)) {
            $logoUrl = $logos[0]['url'] ?? '#'; // Primary logo URL
            $css .= ".site-logo {\n";
            $css .= sprintf("  background-image: url('%s');\n", $logoUrl);
            $css .= "  background-repeat: no-repeat;\n";
            $css .= "  background-size: contain;\n";
            $css .= "  display: block;\n";
            $css .= "  height: 50px; /* Placeholder height */\n";
            $css .= "  width: 150px;  /* Placeholder width */\n";
            $css .= "}\n";
        }

        return $css;
    }
}

Automated Testing for Reliability

Robust testing is paramount for any production integration. We need to test our BrandKitExtractorService in isolation, mocking the external API calls.

tests/Unit/BrandKitExtractorServiceTest.php

namespace Tests\Unit;

use App\Services\BrandKitExtractorService;
use PHPUnit\Framework\TestCase;
use GuzzleHttp\Client; // Assuming Guzzle for mocking example, adjust if using native cURL mock
use GuzzleHttp\Handler\MockHandler;
use GuzzleHttp\HandlerStack;
use GuzzleHttp\Psr7\Response;
use GuzzleHttp\Psr7\Request;

class BrandKitExtractorServiceTest extends TestCase
{
    private MockHandler $mockHandler;
    private BrandKitExtractorService $service;

    protected function setUp(): void
    {
        parent::setUp();

        $this->mockHandler = new MockHandler();
        $handlerStack = HandlerStack::create($this->mockHandler);
        // Note: For native PHP cURL, mocking is more complex. You'd typically use a fake transport.
        // This example uses a common mocking pattern with a PSR-18 client for illustration.
        // If strictly using native cURL, you'd mock the curl_exec and related functions.
        // For simplicity, we'll illustrate the *concept* of mocking the HTTP call.
        // A real native PHP cURL test would involve a dedicated mock transport.
    }

    private function createServiceWithMockedClient(array $responses): BrandKitExtractorService
    {
        // This is a conceptual mock. A true native PHP cURL mock requires more advanced techniques.
        // For demonstration, let's assume a wrapper that uses a PSR-18 client for mocking.
        // If using native cURL, you'd need to mock the curl_* functions directly.

        // Example using a hypothetical `CurlClient` that can be injected with mock responses:
        // $mockCurlClient = new MockCurlClient($responses);
        // $service = new BrandKitExtractorService($mockCurlClient, 'dummy_api_key');

        // For this example, let's simulate success with a valid API key and mock the cURL execution itself.
        // This requires more advanced mocking strategies for PHPUnit, like using AspectMock or Monkey patching,
        // or accepting a PSR-18 client dependency.

        // Let's proceed with the assumption that we have a way to mock curl_exec.
        // A more practical approach for native PHP might be to use a library like `php-curl-class`
        // and mock its methods, or use a test double for the `BrandKitExtractorService` itself.

        // For the sake of clarity in this tutorial, we'll assume a method `setMockResponses` exists
        // on a hypothetical `MockableBrandKitExtractorService` that allows injecting responses.
        // In a real project, this would be handled by injecting a mocked HTTP client.

        // Let's simulate the successful path using a simplified approach.
        // A robust solution would involve mocking `curl_exec`, `curl_getinfo`, etc.
        $mockApiKey = 'test_api_key';
        // We'll have to manually construct the service and then mock its internal cURL calls if not using a library.
        // For this educational purpose, we'll focus on the *expected outcome* of a successful call.

        // --- A MORE REALISTIC NATIVE PHP MOCKING STRATEGY ---
        // You'd typically use a test double for the service and stub its `extract` method,
        // or use a framework's HTTP client mocking if available.
        // If truly stuck with native cURL and no external client:
        // 1. Create a `CurlWrapper` class.
        // 2. Inject this `CurlWrapper` into `BrandKitExtractorService`.
        // 3. In tests, inject a `MockCurlWrapper` that returns predefined results for `exec`, `getinfo`, etc.

        // Given the constraints, we'll focus on the assertions based on *expected* API response.
        // The actual mock implementation would be complex for native cURL.

        // Let's use a placeholder for the service and assume its `extract` method is called with expected params.
        // We will verify the response data structure and content.

        // For this test, we are testing the `validateAndMapResponse` method primarily,
        // and assuming `extract` would call it with valid data.

        // Instantiate the service with a dummy API key.
        return new BrandKitExtractorService('dummy_api_key');
    }

    public function testExtractSuccess(): void
    {
        $websiteUrl = 'https://example.com';
        $expectedBrandKitData = [
            'brand_name' => 'Example Corp',
            'logos' => [['type' => 'primary', 'url' => 'https://example.com/logo.png']],
            'colors' => ['#007bff', '#6c757d'],
            'fonts' => [['name' => 'Arial', 'weight' => 'regular']],
            'imagery' => ['https://example.com/image1.jpg'],
            'social_profiles' => ['twitter' => 'https://twitter.com/example'],
            'css_variables' => ['--primary-color' => '#007bff'],
        ];

        // --- Mocking cURL Execution ---
        // This part is crucial and can be tricky with native cURL.
        // We need to mock `curl_exec`, `curl_getinfo`, `curl_error`, `curl_close`.
        // Using a library like AspectMock or a dedicated test double for cURL functions is best.
        // For this example, we'll simulate the outcome of a successful call.

        // Simulate the successful API response data
        $mockApiResponse = json_encode($expectedBrandKitData);

        // In a real test, you'd use a mocking library to intercept `curl_exec` and return `$mockApiResponse`,
        // `curl_getinfo` to return 200, and `curl_error` to return ''.

        // We will bypass the actual cURL call for this test and directly test the validation logic,
        // assuming `extract` would return the decoded JSON.
        // If using a PSR-18 client, you'd use `Http::fake()` or similar.

        // For the purpose of this tutorial's code example, we'll focus on the validation logic.
        // The `extract` method itself would be tested by mocking the HTTP transport.

        // Test the validation logic directly:
        $service = $this->createServiceWithMockedClient([]); // Not actually using the mock here for direct validation test
        $reflectionMethod = new \ReflectionMethod(BrandKitExtractorService::class, 'validateAndMapResponse');
        $reflectionMethod->setAccessible(true);

        $validatedData = $reflectionMethod->invoke($service, $expectedBrandKitData);

        $this->assertEquals($expectedBrandKitData, $validatedData);
    }

Security Considerations

Beyond storing the API token securely in environment variables, consider these points:

Input Validation: Always validate the websiteUrl input to prevent injection attacks or malformed requests. The service class already checks for emptiness.
Rate Limiting: Be mindful of the API's rate limits. Implement exponential backoff and retry logic for transient errors (e.g., 429 Too Many Requests), but do not retry validation or authentication errors.
HTTPS: Ensure all communication with the API is over HTTPS, which is standard for the provided endpoint.
Data Exposure: Be cautious about logging sensitive API responses or tokens.

Observability and Monitoring

For production applications, robust logging and monitoring are essential. Ensure that your BrandKitExtractorService logs errors with sufficient detail (e.g., the URL attempted, the error message, and the HTTP status code if applicable). This helps in diagnosing issues quickly.

Consider integrating with a logging service (like Monolog) and a monitoring tool to track API response times, error rates, and identify potential bottlenecks or outages.

Deployment Notes

When deploying your application:

Ensure the MIHAJLO_API_TOKEN environment variable is correctly set on your server.
Configure your web server to serve the generated theme draft CSS files from the storage/theme_drafts/ directory (or wherever you choose to store them).
Adjust file permissions for the storage directory if necessary for writing theme drafts.

Common Failures and Troubleshooting

Invalid API Token: A 401 Unauthorized or 403 Forbidden response typically indicates an issue with your API token. Double-check that it's correctly copied and configured in your environment variables. Remember that regenerating the token invalidates the old one.
Network Issues: Connection timeouts or other network errors can occur. Ensure your server has outbound access to ai.mihajlo.mk and that firewalls are not blocking the connection.
Invalid Website URL: The API might return an error if the provided URL is malformed, inaccessible, or doesn't contain enough extractable brand information.
Rate Limiting: If you make too many requests in a short period, you might receive a 429 Too Many Requests error. Implement backoff and retry strategies.
Unexpected API Response Structure: While we validate the response, the API schema could theoretically change. Robust error handling and logging are key to catching these deviations.

Final Verification Checklist

Before considering your integration production-ready, verify the following:

[ ] API token is securely stored in environment variables.
[ ] BrandKitExtractorService correctly instantiates and makes requests to the API endpoint.
[ ] API responses are validated for essential fields and data types.
[ ] Errors (network, API, validation) are caught, logged, and handled gracefully.
[ ] Timeouts for connection and response are set appropriately.
[ ] Basic automated tests exist for the BrandKitExtractorService (mocking external calls).
[ ] Generated theme drafts are saved to a designated directory.
[ ] Generated CSS files are accessible via the web server.
[ ] Appropriate security measures (input validation, no credential hardcoding) are in place.

By following these steps, you can build a powerful, automated system for extracting brand kits and generating landing page theme drafts. This not only streamlines your onboarding process but also provides tangible, data-driven value to your clients right from the start, accelerating their journey to a compelling online presence.
