Traders, For clarity, we are making a minor change to the return type of order cancelation requests. This likely will not affect you. Because it is potentially breaking, the change will be made next week,Friday 27 May at 14:00 UTC. This change is already live on Testnet. The changes are:
When canceling orders, and the orders are found but already canceled, the response code will now be200, not404, as the orders are indeed canceled.
If absolutely no orders matching the filter or IDs are found,/order/cancel/and/order/cancelAllwill continue to return a404.
/orderrejections for single orders will now correctly send a400, not a200. As with bulk orders, the order will be returned in the error'smetavalue.
This was regarded as a bug as bulk orders correctly sent400responses.
