Thank you so much for your help guys, I am extremely happy, with your posts,
due to the fact i have been looking for a good answer for a while now on
outside forums.

I went and implemented the host and peer verification options.
e.g.

       $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, API_ENDPOINT);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, TRUE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
        curl_setopt($ch, CURLOPT_CAINFO, getcwd().CURL_CERT_FRONTEND_PATH);
        curl_setopt($ch, CURLOPT_HEADER, FALSE);
        curl_setopt($ch, CURLOPT_POST, TRUE);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpStr);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

I also read something about getting my own SSL, since i am in development at
the moment i will use openSSL to generate my own cert and use the
cert and password options in my cURL request. I just want to confirm is this
is fine/indented advice, to implement

curl_setopt($ch, CURLOPT_SSLCERT, 'path to the certificate on the calling');
&
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, 'password of the ssl certificate');

using openSSL for now ?

Thank you. :)
