Supplier Cost & Inventory Level
Nosto supports supplier costs and inventory level. The supplier-cost and inventory-level metadata can be used for creating advanced recommendation rules to promote products with a high margin or low-stock products.
The supplier-cost and inventory-level of a product are considered sensitive information and therefore does not exist in the page tagging, and instead, are sent over a secure API. This means that we do not update via crawler/tagging, only via API calls from Prestashop. The cron must be configured in order to send regular API calls.

The extension relies on observers to detect changes to the catalog and synchronize it with Nosto. If you are synchronizing products from your ERP/PIM system, observers may not be triggered.
The supplier-cost and inventory-level metadata collection is always on and does not have a corresponding toggle.
