# MaintenanceWindowLambdaParameters
<a name="API_MaintenanceWindowLambdaParameters"></a>

The parameters for a `LAMBDA` task type.

For information about specifying and updating task parameters, see [RegisterTaskWithMaintenanceWindow](API_RegisterTaskWithMaintenanceWindow.md) and [UpdateMaintenanceWindowTask](API_UpdateMaintenanceWindowTask.md).

**Note**  
 `LoggingInfo` has been deprecated. To specify an Amazon Simple Storage Service (Amazon S3) bucket to contain logs, instead use the `OutputS3BucketName` and `OutputS3KeyPrefix` options in the `TaskInvocationParameters` structure. For information about how AWS Systems Manager handles these options for the supported maintenance window task types, see [MaintenanceWindowTaskInvocationParameters](API_MaintenanceWindowTaskInvocationParameters.md).  
 `TaskParameters` has been deprecated. To specify parameters to pass to a task when it runs, instead use the `Parameters` option in the `TaskInvocationParameters` structure. For information about how Systems Manager handles these options for the supported maintenance window task types, see [MaintenanceWindowTaskInvocationParameters](API_MaintenanceWindowTaskInvocationParameters.md).  
For Lambda tasks, Systems Manager ignores any values specified for TaskParameters and LoggingInfo.
