Why are Products Bought and Categories bought on Deal Objects sometimes blank?

This article explains why on some deals Products Bought and Categories Bought are blank

If you're noticing that "Products Bought" and "Categories Bought" fields on Deal objects in HubSpot are blank, the most common reason is that the deal is in the 'Checkout Abandoned' stage. This happens because the deal represents an abandoned cart, meaning the purchase was not completed. Since the products and categories haven't technically been purchased, Unific does not sync these values.

Once the order is successfully placed, the "Products Bought" and "Categories Bought" fields will automatically update with the relevant information.

Key Point:

Blank Fields: Products and categories aren't displayed for abandoned cart deals.
Field Update: These fields will populate once the purchase is finalized.
