/**
 * <p>
 *             The <code>UpdateNotificationSettings</code> operation creates, updates,
 *             disables or re-enables notifications for a HIT type.
 *             If you call the UpdateNotificationSettings operation for a HIT type that already has a
 *             notification specification, the operation replaces the old specification with a new one.
 *             You can call the UpdateNotificationSettings operation to enable or disable notifications
 *             for the HIT type, without having to modify the notification specification itself by providing
 *             updates to the Active status without specifying a new notification specification.
 *             To change the Active status of a HIT type's notifications,
 *             the HIT type must already have a notification specification,
 *             or one must be provided in the same call to <code>UpdateNotificationSettings</code>.
 *         </p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { MTurkClient, UpdateNotificationSettingsCommand } from "@aws-sdk/client-mturk"; // ES Modules import
 * // const { MTurkClient, UpdateNotificationSettingsCommand } = require("@aws-sdk/client-mturk"); // CommonJS import
 * // import type { MTurkClientConfig } from "@aws-sdk/client-mturk";
 * const config = {}; // type is MTurkClientConfig
 * const client = new MTurkClient(config);
 * const input = { // UpdateNotificationSettingsRequest
 *   HITTypeId: "STRING_VALUE", // required
 *   Notification: { // NotificationSpecification
 *     Destination: "STRING_VALUE", // required
 *     Transport: "Email" || "SQS" || "SNS", // required
 *     Version: "STRING_VALUE", // required
 *     EventTypes: [ // EventTypeList // required
 *       "AssignmentAccepted" || "AssignmentAbandoned" || "AssignmentReturned" || "AssignmentSubmitted" || "AssignmentRejected" || "AssignmentApproved" || "HITCreated" || "HITExpired" || "HITReviewable" || "HITExtended" || "HITDisposed" || "Ping",
 *     ],
 *   },
 *   Active: true || false,
 * };
 * const command = new UpdateNotificationSettingsCommand(input);
 * const response = await client.send(command);
 * // {};
 *
 * ```
 *
 * @param UpdateNotificationSettingsCommandInput - {@link UpdateNotificationSettingsCommandInput}
 * @returns {@link UpdateNotificationSettingsCommandOutput}
 * @see {@link UpdateNotificationSettingsCommandInput} for command's `input` shape.
 * @see {@link UpdateNotificationSettingsCommandOutput} for command's `response` shape.
 * @see {@link MTurkClientResolvedConfig | config} for MTurkClient's `config` shape.
