// ABOUT THIS NODE.JS SAMPLE: This sample is part of the SDK for JavaScript Developer Guide topic at
// https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/sns-examples-managing-topics.html 

// snippet-start:[sns.JavaScript.topics.setTopicAttributes]
// Load the AWS SDK for Node.js
var AWS = require('aws-sdk');
// Set region
AWS.config.update({region: 'REGION'});

// Create setTopicAttributes parameters
var params = {
  AttributeName: 'ATTRIBUTE_NAME', /* required */

// Create promise and SNS service object
var setTopicAttribsPromise = new AWS.SNS({apiVersion: '2010-03-31'}).setTopicAttributes(params).promise();

// Handle promise's fulfilled/rejected states
setTopicAttribsPromise.then(
