Orders with a existing externalRefID now returns status code 200
2 days ago by Don Fogarty
This change fixes a long-standing oversight. Now, when an order is submitted using the POST /orders endpoint with an already used (reused) externalRefID, it returns a 200 status code instead of 201. The returned payload will remain the same, returning the original payload from the existing externalRefID, preventing a duplicate order.
