To use product listing, you need to provide a mapping between categories and products. The default mapping used in our services is id -> category_id. This means that we expect your category object to contain the attribute id, and your product object to contain attribute category_id. The default mapping cannot be changed by you, but if you wish to change it, please contact our support at, we are glad to help!

If you try to integrate a product listing while using invalid mapping, you will see an error message saying Error creating query - invalid category attribute or Could not find attribute <attribute_name> in your category structure.
