I'm having problems with this. I uploaded fedex_subscribe.php to my server, opened in firefox, filled out the form and submitted. I get the following error:
Fatal error: Call to undefined function curl_init() in /var/www/skullcrow/fedex_subscribe.php on line 28
Best as I can tell from the page below, is that you have to call fedex directly and ask for a test meter number until they verify that your page is working properly, then they provide a production meter number.
I have another question about this too... our company outsources production and shipping and we don't actually ship anything out from here. Will ecart allow us to set it up to JUST fetch shipping costs to display? All of our shipping costs are billed to us by our drop shipper so I don't think we really need to access our fedex account or supply a meter number for that. The checkout wizard doesn't appear to support this... unless I missed something.
