# Order Cancel Request

> Cancel a single order via FIX

<div className="api-banner">
  <span className="api-protocol fix">FIX</span>
  <span className="api-detail">session: trading</span>
  <span className="api-tag">35=F</span>
</div>

Cancel a single GTD or GTC order.

A successful order cancellation will result in an [execution report](/exchange/api-reference/unified-fix/er) with the OrdStatus set to 4 (Cancelled).
Unsuccessful cancellation requests will result in a [business level reject](/exchange/api-reference/unified-fix/reject-business) message with the reason of the rejection.

<ResponseField name="header" type="" required>35=`F`</ResponseField>

<ResponseField name="11 - ClOrdID" type="string" required>
  Unique identifier of the order. The ID can be one of the following formats:

  * **Ever-Increasing Positive Numbers**: Ever-increasing positive numbers, such as microsecond timestamps, to ensure the uniqueness and sequential nature of the identifiers.
    **Example**: Using the current microsecond timestamp as the ClOrdID, such as `1623448294234000` (Max 18 characters)
  * **Timestamp-First v4 UUIDs**: A timestamp-first v4 UUID might look like `1b4e28ba-2fa1-11d2-883f-0016d3cca427`, where the initial part (`1b4e28ba-2fa1`) of the UUID represents the timestamp. The timestamp granularity to generate the first part needs to be 10 microseconds maximum such as `162344829423400`.
