# GET List backboards

Lists the customiser's backboard options in the order the storefront presents them (`sort_order`, then id). `base_price` is integer minor units of `currency`; `price_per_sq_cm` is a decimal major-unit rate, the same units the pricing document uses. Image fields and the whole `geometry` object are read-only. Requires `customisers:read`. Follow `links.next` while `pagination.has_more` is true, sending each cursor back unchanged. The operation is read-only and always safe to retry.
