Try This:

<?php
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,"https://api.clickbank.com/rest/1.3/products/list?site=<your unique affiliate id>");
    curl_setopt($ch, CURLOPT_HEADER, true); 
    curl_setopt($ch, CURLOPT_HTTPGET, true); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("Accept: application/xml", "Authorization:DEV-KEY:API-KEY"));
    $result = curl_exec($ch);
    curl_close($ch);

    print $result;

    ?>

It's expecting a parameter called site. Please see the docs here: https://api.clickbank.com/rest/1.3/products
