Custom integration typically involves:
php
// Example: Making an API request to a third-party service
function my_api_request() {
$api_url = ‘https://api.example.com/endpoint’;
$response = wp_remote_get( $api_url, array(
‘headers’ => array(
‘Authorization’ => ‘Bearer YOUR_API_KEY’,
)
));
if ( is_wp_error( $response ) ) {
return false;
}
return json_decode( wp_remote_retrieve_body( $response ), true );
}
Integrating APIs with Drupal
Known for its enterprise-level capabilities and flexibility, Drupal excels in handling complex API integrations across large-scale implementations.
Leveraging Drupal Modules
Drupal’s modular architecture provides powerful tools for API integration through both core and contributed modules:
| Module | Features | Use Cases |
|---|---|---|
| JSON | RESTful data exchange, standardized format | Content syndication, headless CMS implementation |
| RESTful Web Services | Custom API endpoints, various formats | Custom integrations, legacy system connectivity |
| Services | Supports multiple protocols, custom endpoints | Complex enterprise integrations |
| Consumers | OAuth2 authentication | Secure third-party connections |
| GraphQL | Query language for APIs | Flexible data requests, reduced over-fetching |
The JSON
module (now part of Drupal core) offers a standardized approach to API implementation following the JSON
specification, making it particularly valuable for creating consistent integrations.
Custom Module Development
For specialized requirements, Drupal’s robust framework supports custom module development for API integration:
- Create a custom module structure
- Implement service classes for API communication
- Use Drupal’s service container for dependency management
- Define routes and controllers for handling data
Example implementation:
php
// Example: Service class for API integration in Drupal
namespace Drupal\my_api_module\Service;
class ApiService {
protected $httpClient;
public function __construct(ClientInterface $http_client) {
$this->httpClient = $http_client;
}
public function fetchData($endpoint) {
try {
$response = $this->httpClient->request(‘GET’, $endpoint, [
‘headers’ => [
‘Authorization’ => ‘Bearer ‘ . $this->getApiKey(),
],
]);
return json_decode($response->getBody(), TRUE);
}
catch (\Exception $e) {
\Drupal::logger(‘my_api_module’)->error($e->getMessage());
return NULL;
}
}
}
Integrating APIs with Joomla
Joomla combines robust architecture with user-friendly administration, providing multiple avenues for API integration.
Using Extensions for API Integration
Joomla’s extension directory offers numerous solutions for connecting with external services:

php
// Example: Joomla plugin for API integration
defined(‘_JEXEC’) or die;
use Joomla\CMS\Plugin\CMSPlugin;
use Joomla\CMS\Http\HttpFactory;
class PlgSystemMyApiIntegration extends CMSPlugin
{
public function onAfterInitialise()
{
$app = JFactory::getApplication();
if ($app->isClient(‘administrator’)) {
return;
}
try {
$http = HttpFactory::getHttp();
$response = $http->get(‘https://api.example.com/data’, [
‘headers’ => [‘Authorization’ => ‘Bearer ‘ . $this->params->get(‘api_key’)]
]);
if ($response->code == 200) {
$this->processApiData(json_decode($response->body));
}
} catch (Exception $e) {
JLog::add($e->getMessage(), JLog::ERROR);
}
}
protected function processApiData($data)
{
// Process the API response data
}
}
