What a group to bring together, eh?
I’m using the following:
http://www.wordpress.org
http://www.shopplugin.net
http://www.mediatemple.net
http://curl.haxx.se/
So first off, I had an issue where the FirstData plugin built by Shopp was pointing to the incorrect URL:
var $url = “https://secure.linkpt.net/lpcentral/servlet/lppay”;
This url is actually FirstData’s ‘Connect’ url… which is a forms based api… but the Shopp Plugin FirstData gateway plugin actually uses FirstData’s ‘Global Gateway Api’, but this is not the URL that they are...
