Error Handling

The plugin uses the LongswipeException class for error handling. Always wrap your API calls in try-catch blocks:

try {
    // Your API call here
} catch (LongswipeException $e) {
    echo "Error Code: " . $e->getCode() . "\n";
    echo "Error Message: " . $e->getMessage() . "\n";
    if ($e->getErrorData()) {
        echo "Additional Error Data: ";
        print_r($e->getErrorData());
    }
}
