❗️
This API only supports the application/json Content-Type format. Please note that requesting with other formats such as query parameters or form-data are not supported.

❗️
new_identifier and prev_order_identifier must be different.
The identifier is a key value that is issued directly by the user, not the UUID that is issued by the service. It is used to uniquely identify orders and must be unique for each order. Therefore, when canceling an order and placing a new one, a new identifier is required.
Additionally, if an error occurs during the request, please do not resend the request with the same identifier and generate a new identifier for each request.

New Order
The new order will be placed in the same market as the existing order after the existing order (corresponding to prev_order_uuid or prev_order_identifier) has been completely canceled.
If the new order has been successfully placed, you can query it by new_order_uuid provided in the response or new_identifier specified by the user upon request.
Even if the cancel and new request is successfully submitted, a new order won’t be created if the previous existing order has been fully filled before the cancellation.
