The product object

A product is something sealed: a booster box, an elite trainer box, a collection tin. Products are priced like cards and tracked the same way, but they hold cards rather than being one. Unlike every other id here, a product id is a number, not a string.

array

The expansions this product belongs to, as { id, name }. Usually one entry, but not always — a Trainer Kit box ships two decks, and both are its expansions, so the field is an array rather than a single expansion_id. It can also be empty: such a product is still on List products, it just cannot be reached by expansion_id.
