We provide a data feed for use with Klaviyo, automatically generated by the CMS. The provides information on all products, including products on multiple shopping pages.
There is no issue with connecting your feed as supplied by the Klaviyo plugin, as either a Data Feed or a Catalogue.
Contact Klaviyo support with any questions around using the feed with their platform.
You need to map the required fields in the catalogue setup area. E.g.
Configure Field Mapping
All item fields in your feed must be mapped to Klaviyo fields. There are five required fields that must be present and mapped correctly: $id, $title, $description, $link, $image_link.
The feed providided by the plugin sends data such as product title and description, which needs to map to a klaviyo value. e.g the feed has a value for PID (Product id), which needs to map to $id in klaviyo or the like.
Only some fields are required, not all. If these fields are correct and you have other fields mapped, try setting these to not required.
If still an issue Klaviyo support should be able to provide assistance.
