GET
Get an order by ID
GET /orders-v3/{orderId} returns one order belonging to the authenticated account. Unlike GET /orders-v3, this is not limited to orders resting on the book — filled, cancelled, and expired orders are returned when they still exist. Pass the signed order ID: the same value as id on order rows and orderId from POST /orders-v3.
A missing id, or an id that belongs to another account, returns 404. The response does not distinguish those cases.
