Cancel a single open order by {id}.


Cancel a previously placed order. Order must belong to the profile that the API key belongs to.

If the order had no matches during its lifetime its record may be purged. This means the order details will not be available with GET /orders/<id>.

API Key Permissions

This endpoint requires the "trade" permission.

Orders may be canceled using either the exchange assigned id or the client assigned client_oid. When using client_oid it must be preceded by the client: namespace.


Successfully cancelled order response will include the order ID if requested cancellation is by exchange assigned id, or the client assigned client_oid if cancelled by client order ID.

Cancel Reject

If the order could not be canceled (already filled or previously canceled, etc), then an error response will indicate the reason in the message field.
