Cancel an order

POST /v1/cancel
Request
{ "maker": "0x1111…", "nonce": 43, "orderNonce": 42, "signature": "0x…" }
body makeraddressrequired
The account.
body nonceuint64required
The cancel's own nonce, from the same space as the account's orders.
body orderNonceuint64required
The nonce of the order to cancel. You can cancel an order before you have seen its acknowledgement.
body signaturestringrequired
The EIP-712 Cancel, by the maker or a key it registered.
200 OK
{ "status": "cancelled" }
status is cancelled, unknown (no answer in time; check the order), or the engine's refusal code, such as ORDER_NONCE_NOT_FOUND when the order is not resting. An engine refusal is still a 200.
Cancels are accepted even while order entry is paused.
