For our ecommerce clients I am listing out their orders from the v2/orders/search api. I also need to retrieve the image url and link url (when possible) for a given line item on each order. Is this possible?
Yes, this is possible. You can use the catalog_object_id to get the catalog object which will have the image_id. With that ID you can RetrieveCatalogObject or BatchRetrieveCatalogObjects to get the image URL.
