Plus, it may not include the shipping address either, if the order will be sent to somewhere else apart from the customer’s own addresses (inside the “customer card”).
There is a hierarchy-tree for the “shipping address” at “POST /v2/orders/batch-retrieve - Square API Reference” as I was also replied for my own question at –
"Coordinates of the recipient (customer) location [delivery point]" within a certain delivery order - #5 by mustafa – as follow;
“batch-retrieve-orders”–> “Order” → “OrderFullfillment” → “OrderFullfilmentShipmentDetails” (in “beta”) → “OrderFulfillmentRecipient” (in “beta”) → “address” (in “beta”) .
Hope it may help.
