EasyRoutes automatically reads the delivery date and time window that a date picker writes onto each Shopify order — most often as order attributes (note attributes), and also from order tags. It recognizes common attribute names such as "Delivery Date," "Delivery Time," and "Order Due Time" used by popular apps, then surfaces them in the Delivery Date and Time Window columns for filtering and routing. Metafields aren't read directly; use Shopify Flow to copy them into an order attribute. This works the same whether data comes from Zapiet, Buunto, or another supported app.
