Hi! I am working with a client that has switched from Shopify to a custom Ecom. So essentially the conversion metrics have become custom Placed orders and the catalog is a custom JSON feed. My question is whether the personalization options like “Products a customer may like” based on view or purchase history will still work?
ie what I am showing below:

I am finding that everyone is getting displayed the same product feed and its not reflective of their individual view history. Is this a feature that is only designed to work for Shopify or is there a prescribed data format for the custom Viewed Product and Placed order event in order for this to work?
Please advise.
