# StopQuery
<a name="API_StopQuery"></a>

Stops a CloudWatch Logs Insights query that is in progress. If the query has already ended, the operation returns an error indicating that the specified query is not running.

This operation can be used to cancel both interactive queries and individual scheduled query executions. When used with scheduled queries, `StopQuery` cancels only the specific execution identified by the query ID, not the scheduled query configuration itself.
