Are there any best practices for integrating third-party APIs, such as cloud-based OCR services, into a locally hosted PHP application?

When integrating third-party APIs, such as cloud-based OCR services, into a locally hosted PHP application, it is important to securely handle API keys and credentials, properly format and send requests to the API, handle responses effectively, and implement error handling to gracefully manage any issues that may arise. 

// Example code snippet for integrating a cloud-based OCR service API in PHP

// API endpoint and credentials
$api_url = 'https://api.ocrservice.com/OCR';
$api_key = 'your_api_key_here';

// Sample image file to be processed
$image_path = 'path/to/image.jpg';

// Send POST request to the API
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, [
    'apikey' => $api_key,
    'file' => new CURLFile($image_path)
]);
$response = curl_exec($ch);

// Handle API response
if (curl_errno($ch)) {
    echo 'Error: ' . curl_error($ch);
} else {
    $decoded_response = json_decode($response, true);
    if ($decoded_response && isset($decoded_response['ParsedResults'])) {
        // Process OCR results
        $ocr_text = $decoded_response['ParsedResults'][0]['ParsedText'];
        echo 'OCR Text: ' . $ocr_text;
    } else {
        echo 'Error processing OCR response';
    }
}

// Close cURL connection
curl_close($ch);
