$config = SendinBlue\Client\Configuration::getDefaultConfiguration()->setApiKey('api-key', 'YOUR_API_KEY');
$apiInstance = new SendinBlue\Client\Api\SMTPApi(new GuzzleHttp\Client(),$config);

try {
    $result = $apiInstance->sendTransacEmail($sendSmtpEmail);
    print_r($result);
} catch (Exception $e) {
    echo 'Exception when calling SMTPApi->sendTransacEmail: ', $e->getMessage(), PHP_EOL;

According to the SendSmtpEmailAttachment documentation, you have two ways to attach a file using a url or a content.

url | Absolute url of the attachment (no local file).

content | Base64 encoded chunk data of the attachment generated on the fly

You are wrongly assigning "utf-8" to the content. This mean you need to convert the pdf data into a base64 chunk data. First, get the pdf path in your server as $pdfdocPath. Get the pdf content using file_get_contents method and encode it using base64_encode method. Finally, split the content in small chunks using chunk_split as shown in the next snippet:

$sendSmtpEmail = new \SendinBlue\Client\Model\SendSmtpEmail(); 
$sendSmtpEmail['to'] = array(array('email'=>'[email protected]'));
$sendSmtpEmail['templateId'] = 39;
$sendSmtpEmail['params'] = array(
'NUMEROFACTURE'=> "12345",
'CODECLIENT' => "1234567",
'TOSEND' => "[email protected]",
'MONTANTFACTURE'=>  number_format(12, 2, ',', ' '),
);
$pdfdocPath = __DIR__.'/facture/Facture-'.$row["ClePiece"].'.pdf';
$b64Doc = chunk_split(base64_encode(file_get_contents($pdfdocPath)));
$attachement = new \SendinBlue\Client\Model\SendSmtpEmailAttachment();
$attachement['name']= 'Facture-'.$row["ClePiece"].'.pdf';
$attachement['content']= $b64Doc;
$sendSmtpEmail['attachment']= $attachement;
$sendSmtpEmail['headers'] = array('Content-Type'=>'application/pdf','Content-Disposition'=>'attachment','filename'=>'Facture-'.$row["ClePiece"].'.pdf',"charset"=>"utf-8");

Update:

I checked the APIv3-php-library source code and I found that the constructor will do the validation of name and content.

$dataEmail = new \SendinBlue\Client\Model\SendEmail();
$dataEmail['emailTo'] = ['[email protected]', '[email protected]'];
// PDF wrapper
$pdfDocPath = __DIR__.'/facture/Facture-'.$row["ClePiece"].'.pdf';
$content = chunk_split(base64_encode(file_get_contents($pdfDocPath)));
// Ends pdf wrapper
$attachment_item = array(
        'name'=>'Facture-'.$row["ClePiece"].'.pdf',
        'content'=>$content
);
$attachment_list = array($attachment_item);
// Ends pdf wrapper

$dataEmail['attachment']    = $attachment_list;

$templateId = 39;

$config = SendinBlue\Client\Configuration::getDefaultConfiguration()->setApiKey('api-key', 'YOUR_API_KEY');

$apiInstance = new SendinBlue\Client\Api\SMTPApi(new GuzzleHttp\Client(),$config);
try {
    $result = $apiInstance->sendTemplate($templateId, $dataEmail);
    print_r($result);
} catch (Exception $e) {
    echo 'Exception when calling SMTPApi->sendTemplate: ', $e->getMessage(), PHP_EOL;
}
