Api cancel order request

ApiCancelOrderRequest

Cancel an order on the orderbook for this trading account. Either order_id or client_order_id must be provided.

Name Lite	Type	Required Default	Description
sub_account_id sa	string	True	The subaccount ID cancelling the order
order_id oi	string	False 0	Cancel the order with this order_id
client_order_id co	string	False 0	Cancel the order with this client_order_id
time_to_live_ms tt	string	False 100	Specifies the time-to-live (in milliseconds) for this cancellation. During this period, any order creation with a matching client_order_id will be cancelled and not be added to the GRVT matching engine. This mechanism helps mitigate time-of-flight issues where cancellations might arrive before the corresponding orders. Hence, cancellation by order_id ignores this field as the exchange can only assign order_ids to already-processed order creations. The duration cannot be negative, is rounded down to the nearest 100ms (e.g., '670' -> '600', '30' -> '0') and capped at 5 seconds (i.e., '5000'). Value of '0' or omission results in the default time-to-live value being applied. If the caller requests multiple successive cancellations for a given order, such that the time-to-live windows overlap, only the first request will be considered.
