Hey,
I need to use the API to retrieve some global parameters from a js custom file. I tried to put your sample code in a php file :

    $fullUrl="localhost/ipmp_new/api/Parameter/list/all"; 
    $curl = curl_init($fullUrl);
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($curl, CURLOPT_USERPWD, "projeqtor:projeqtor");
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    $curl_response = curl_exec($curl);
    echo $curl_response;
    curl_close($curl);

But this give me a HTTP 500 error and I don't see any log in the project log file :'(

Do you have any idea why?
