The following code examples show how to use SetTopicAttributes.

CLI
Amazon CLI

To set an attribute for a topic

The following set-topic-attributes example sets the DisplayName attribute for the specified topic.

aws sns set-topic-attributes \ --topic-arn arn:aws:sns:us-west-2:123456789012:MyTopic \ --attribute-name DisplayName \ --attribute-value MyTopicDisplayName

This command produces no output.

Create the client in a separate module and export it.

import { SNSClient } from "@aws-sdk/client-sns"; // The AWS Region can be provided here using the `region` property. If you leave it blank // the SDK will default to the region set in your AWS config. export const snsClient = new SNSClient({});

Import the SDK and client modules and call the API.

import { SetTopicAttributesCommand } from "@aws-sdk/client-sns"; import { snsClient } from "../libs/snsClient.js"; export const setTopicAttributes = async ( topicArn = "TOPIC_ARN", attributeName = "DisplayName", attributeValue = "Test Topic", ) => { const response = await snsClient.send( new SetTopicAttributesCommand({ AttributeName: attributeName, AttributeValue: attributeValue, TopicArn: topicArn, }), ); console.log(response); // { // '$metadata': { // httpStatusCode: 200, // requestId: 'd1b08d0e-e9a4-54c3-b8b1-d03238d2b935', // extendedRequestId: undefined, // cfId: undefined, // attempts: 1, // totalRetryDelay: 0 // } // } return response; };
