    using System.Net;
    using System.Security.Cryptography.X509Certificates;
    public class TrustAllCertsPolicy : ICertificatePolicy {
        public bool CheckValidationResult(
            ServicePoint srvPoint, X509Certificate certificate,
            WebRequest request, int certificateProblem) {
                return true;
            }
    }
"@
[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy


$url = 'http://github.fuze.org/api/Lists/GetList'
$acctname = 'administartor'
$password = 'M00nd4t'

$encodedCredentials =  [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes("$($acctname):$($password)"))

$headers = @{

Bad request errors generally mean that the payload being sent is of in-correct format. Try changing body to:

$body = @'
{
"faceid": "431494039483185",
"Id": "7647484953",
"r": "1444",
"session":""
}
'@
