Google Translate API Integration in PrestaShop (PHP Example):

$text = "Hello, how are you?";
$targetLang = "es";

$url = "https://translation.googleapis.com/language/translate/v2?key=$apiKey&q=".urlencode($text)."&target=$targetLang";

$response = file_get_contents($url);
$json = json_decode($response, true);

echo $json['data']['translations'][0]['translatedText']; // "Hola, ¿cómo estás?"

)

print(response['choices'][0]['message']['content'])  # "Hola, ¿cómo estás?"
