so based on that you are looking to add it to the .wsdl file
but I don't understand their actual statement.
No, I don't think it would go in the .wsdl file as that is a straight XML file.
I'm going to try it at the very beginning of the /catalog/includes/modules/shipping/fedexwebservices.php file as it's (possibly) the only place it could go.
Right now, I'm running the file just as you guys wrote it and I'm getting the HTTP 500 error, however, when I put the absolute path in, I get the same error, so, it's probably not that which is causing the error.
Edit: OK, that was much better. With the require_once statement in there, not only do I get the HTTP 500 error, but the shipping module list in admin only shows the one shipping option before the FedEx one even if the FedEx module is disabled.
Curious stuff here.....
