A platform that sends its own API key (Authorization: Bearer mp_live_...) can additionally cancel an order THAT KEY created while it is confirmed or printing — that is how you stop a press when your customer cancels on your side. shipped and delivered can never be canceled; that is a refund, contact support (see get_catalog). Once printing has started, canceling (creating key only) stops production but moves no money. Canceling releases the order's client_reference — replaying that reference afterwards creates a new order and prints it.
