use PaypalServerSdkLib\Logging\ResponseLoggingConfigurationBuilder;
use Psr\Log\LogLevel;
use PaypalServerSdkLib\Environment;
use PaypalServerSdkLib\Authentication\ClientCredentialsAuthCredentialsBuilder;
use PaypalServerSdkLib\PaypalServerSdkClientBuilder;

$client = PaypalServerSdkClientBuilder::init()
    ->clientCredentialsAuthCredentials(
        ClientCredentialsAuthCredentialsBuilder::init(
            'OAuthClientId',
            'OAuthClientSecret'
        )
    )
    ->environment(Environment::SANDBOX)
    ->loggingConfiguration(
        LoggingConfigurationBuilder::init()
            ->level(LogLevel::INFO)
            ->requestConfiguration(RequestLoggingConfigurationBuilder::init()->body(true))
            ->responseConfiguration(ResponseLoggingConfigurationBuilder::init()->headers(true))
