Provisioning module calling params

[serveria]

Hi,

I wonder what's the correct way to call module params from a Create Account function below:

function provisioningmodule_CreateAccount(array $params)
{
    try {
        
   $result = shell_exec("wget -O - --quiet --http-user=xxxx --http-passwd=xxxxxx --no-check-certificate 'https://xxx.xxx.xxx.xxx:10000/virtual-server/remote.cgi?program=create-user&domain=xxxxxx.com&user=jimmy&pass=12345&quota=1024'");

    }

We need to grab user, pass and quota fields from an order form.

Anyone?
