# Cancel

If an image processing job is no longer needed or was started in error, you can cancel it before it completes. The job must be in a cancellable state (e.g., not already completed or failed) for the request to be successful.

## Cancel

> Cancel a pending image processing job. If the job has already completed, or if it is not in a cancellable state, this request will fail with a conflict error. Use this to prevent unnecessary costs for jobs started in error.<br>
