Step by Step Guide to Building a KW Command API Integration in PHP

Introduction

Hey there, fellow developer! Ready to dive into the world of KW Command API integration? You're in for a treat. This guide will walk you through building a robust PHP integration with the KW Command API. We'll cover everything from setup to deployment, so buckle up and let's get coding!

Prerequisites

Before we jump in, make sure you've got:

• PHP 7.4 or higher (because who doesn't love those sweet, sweet type hints?)
• Composer (your trusty dependency manager)
• KW Command API credentials (you can't enter without a ticket!)

Setting Up the Development Environment

First things first, let's get our environment ready:

composer require guzzlehttp/guzzle
composer require league/oauth2-client

Now, create a .env file for your API credentials:

KW_CLIENT_ID=your_client_id
KW_CLIENT_SECRET=your_client_secret
KW_REDIRECT_URI=your_redirect_uri

Authentication

Time to tackle OAuth 2.0. Don't worry, it's not as scary as it sounds!

use League\OAuth2\Client\Provider\GenericProvider;

$provider = new GenericProvider([
    'clientId'     => getenv('KW_CLIENT_ID'),
    'clientSecret' => getenv('KW_CLIENT_SECRET'),
    'redirectUri'  => getenv('KW_REDIRECT_URI'),
    'urlAuthorize' => 'https://api.kwcommand.com/oauth2/authorize',
    'urlAccessToken' => 'https://api.kwcommand.com/oauth2/token',
    'urlResourceOwnerDetails' => 'https://api.kwcommand.com/v1/me'
]);

Making API Requests

Let's create a base API client class:

class KWCommandClient
{
    private $client;
    private $accessToken;

    public function __construct($accessToken)
    {
        $this->client = new \GuzzleHttp\Client(['base_uri' => 'https://api.kwcommand.com/']);
        $this->accessToken = $accessToken;
    }

    public function request($method, $endpoint, $options = [])
    {
        $options['headers']['Authorization'] = 'Bearer ' . $this->accessToken;
        return $this->client->request($method, $endpoint, $options);
    }
}

Implementing Key Endpoints

Now for the fun part - let's implement some endpoints!

// Get contacts
$response = $client->request('GET', 'v1/contacts');

// Create a listing
$response = $client->request('POST', 'v1/listings', [
    'json' => [
        'address' => '123 Main St',
        'price' => 500000,
        // ... other listing details
    ]
]);

Data Synchronization

To keep your data fresh, implement webhooks:

// In your webhook endpoint
$payload = json_decode(file_get_contents('php://input'), true);
if ($payload['event'] === 'contact.updated') {
    // Update your local database
}

Error Handling and Logging

Always be prepared for the unexpected:

try {
    $response = $client->request('GET', 'v1/contacts');
} catch (\GuzzleHttp\Exception\ClientException $e) {
    $errorResponse = $e->getResponse();
    $errorContent = json_decode($errorResponse->getBody()->getContents(), true);
    // Log the error
    error_log('KW Command API Error: ' . $errorContent['message']);
}

Testing

Don't forget to test your integration:

public function testGetContacts()
{
    $mockClient = $this->createMock(KWCommandClient::class);
    $mockClient->expects($this->once())
               ->method('request')
               ->with('GET', 'v1/contacts')
               ->willReturn(/* mocked response */);
    
    // Perform assertions
}

Deployment Considerations

As you prepare to deploy, remember:

• Keep your API credentials secure
• Implement proper error handling and logging
• Consider caching to improve performance

Conclusion

And there you have it! You've just built a KW Command API integration in PHP. Pat yourself on the back, you coding wizard! Remember, practice makes perfect, so keep experimenting and refining your integration.
