www.mycreloadedstore.com/catalog/admin/webgility/eCCxml.php
www.mycreloadedstore.com/catalog/admin/webgility/eCCcreservice.php
www.mycreloadedstore.com/catalog/admin/webgility/lib (Place all the files from the lib folder here)
Your online store module URL is: http://www.mycreloadedstore.com/catalog/admin/webgility/eCCcreservice.php (change the domain name to match your site)
To ensure that your hosting provider and online store meet the requirements for eCC to connect properly, we’ve created a test file. Visit this URL and enter your admin login and password: http://www.mycreloadedstore.com/catalog/admin/webgility/eCCtest.php. The test file will provide details on your configuration and flag any requirements that are not met. Please contact your hosting provider if any system requirements are not met. If you have any questions related to the online store module, please visit http://support.webgility.com to submit a support ticket.
