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 firstname.lastname@example.org, 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.
