You are using one of our Opencart integration modules. Based on various shop configurations here are the most common issues:
Product URL’s are not valid
catalog/controller/module/VTfeed_opencart.php?sef=on
When we synchronize product information, the endpoint accepts variables to make changes to the exported data. For sef param, you can set the following values: on, off and v2. Default is off
I do not want product combinations to be exported
catalog/controller/module/VTfeed_opencart.php?combinations=off
By default we export combinations of the products.
Values for combination param: off and on. Default is on
