Example Responses:
The first example response indicates a successful order submission because it includes an id, orderHash, status, and other relevant order details. The status is "NOT_STARTED", meaning the order has been created but not yet processed.
The second response, { "error": "Validation failed with error" }, indicates a failed submission due to a validation issue, likely caused by missing or incorrect parameters in the request.
