# Cancel SQL Query

Use the `DELETE /api/v3/query/{queryId}` endpoint of the Data 360 Query API to cancel a running query and release its associated server resources. This operation is idempotent — repeated calls for the same query ID always return `204 No Content` with no additional effect. Use this endpoint to free resources when a query is no longer needed or has exceeded an acceptable runtime.

## Syntax

- **HTTP Method**: DELETE
- **Format**: REST
- **URI**: `/api/v3/query/{queryId}`

## Path Parameters

| Parameter | Type   | Description                                                                                                                   |
| --------- | ------ | ----------------------------------------------------------------------------------------------------------------------------- |
| `queryId` | string | Required. The unique identifier of the query returned from `POST /api/v3/query`. Example: `MTAuMjcuMTgxLjE0OTo3NDg0_1cfc8d35`. |
