OpenTicket API - text formatting issue

[Remitur]

According to https://developers.whmcs.com/api-reference/openticket/ , it seems that it's possible text formatting using the same syntax available in the ticket web text editor; that's to say, their code sample:

$command = 'OpenTicket';
$postData = array(
    'deptid' => '1',
    'subject' => 'This is a sample ticket',
    'message' => 'This is a **sample** ticket message',
    'clientid' => '1',
    'priority' => 'Medium',
    'markdown' => true,
    'attachments' => base64_encode(json_encode([['name' => 'sample_text_file.txt', 'data' => base64_encode('This is a sample text file contents')]])),
);
$adminUsername = 'ADMIN_USERNAME'; // Optional for WHMCS 7.2 and later

$results = localAPI($command, $postData, $adminUsername);
print_r($results);

suggests that "sample" should be bold.
And, if I insert *sample*, it will be italic, and so on...

But (for me) it doesn't work: if I use that syntax, I get exactly the same message, without any text formatting; that's to say, if I specify

$textmessage = $textmessage ."\r\n[Text to display](http://www.example.com)";    
  
$textmessage = $textmessage ."\r\n**bold**\r\n*italic*\r\n### Small header\r\n";

the text I will get in the ticket will be:

Quote

 [Text to display](http://www.example.com)
**bold**
*italic*
### Small header

Am I missing something, or is the doc wrong?

Using that example code works for me except the attachment doesn't come in.  The word "sample" is bold as expected though.   What version of WHMCS are you using?

Tried on my dev environment with 7.6.1 ...    😮

Will do a try on production environment too (even if I can't imagine what may be the possible reason...)

My dev that I tested on is 7.6.1 also.  So seems to be something special with your dev setup.
