Cancel a sale

​

Cancels one of your sales. The order moves to cancelled_seller, the buyer is refunded in full, and the cards return to your inventory.

The order must be awaiting dispatch (pending_shipment). Any other status returns 409 INVALID_STATUS.

reasonText is shown to the buyer along with the reason code, and both appear on the sale's cancellation afterwards.

Returns the updated sale, in the same shape as GET /v1/sales/{orderNumber}.

Send an Idempotency-Key header to make retries safe: the same key returns the same response for 24 hours.

Requires the sales:write scope.
