Use PutBucketNotificationConfiguration with an Amazon SDK or CLI

The following code examples show how to use PutBucketNotificationConfiguration.

Amazon SDK for .NET

There's more on GitHub. Find the complete example and learn how to set up and run in the Amazon Code Examples Repository.

using System; using System.Collections.Generic; using System.Threading.Tasks; using Amazon.S3; using Amazon.S3.Model; /// <summary> /// This example shows how to enable notifications for an Amazon Simple /// Storage Service (Amazon S3) bucket. /// </summary> public class EnableNotifications { public static async Task Main() { const string bucketName = "doc-example-bucket1"; const string snsTopic = "arn:aws:sns:us-east-2:0123456789ab:bucket-notify"; const string sqsQueue = "arn:aws:sqs:us-east-2:0123456789ab:Example_Queue"; IAmazonS3 client = new AmazonS3Client(Amazon.RegionEndpoint.USEast2); await EnableNotificationAsync(client, bucketName, snsTopic, sqsQueue); } /// <summary> /// This method makes the call to the PutBucketNotificationAsync method. /// </summary> /// <param name="client">An initialized Amazon S3 client used to call /// the PutBucketNotificationAsync method.</param> /// <param name="bucketName">The name of the bucket for which /// notifications will be turned on.</param> /// <param name="snsTopic">The ARN for the Amazon Simple Notification /// Service (Amazon SNS) topic associated with the S3 bucket.</param> /// <param name="sqsQueue">The ARN of the Amazon Simple Queue Service /// (Amazon SQS) queue to which notifications will be pushed.</param> public static async Task EnableNotificationAsync( IAmazonS3 client, string bucketName, string snsTopic, string sqsQueue) { try { // The bucket for which we are setting up notifications. var request = new PutBucketNotificationRequest() { BucketName = bucketName, }; // Defines the topic to use when sending a notification. var topicConfig = new TopicConfiguration() { Events = new List<EventType> { EventType.ObjectCreatedCopy }, Topic = snsTopic, }; request.TopicConfigurations = new List<TopicConfiguration> { topicConfig, }; request.QueueConfigurations = new List<QueueConfiguration> { new QueueConfiguration() { Events = new List<EventType> { EventType.ObjectCreatedPut }, Queue = sqsQueue, }, }; // Now apply the notification settings to the bucket. PutBucketNotificationResponse response = await client.PutBucketNotificationAsync(request); } catch (AmazonS3Exception ex) { Console.WriteLine($"Error: {ex.Message}"); } } }
Amazon CLI

To enable the specified notifications to a bucket

The following put-bucket-notification-configuration example applies a notification configuration to a bucket named my-bucket. The file notification.json is a JSON document in the current folder that specifies an SNS topic and an event type to monitor.

aws s3api put-bucket-notification-configuration \ --bucket my-bucket \ --notification-configuration file://notification.json

Contents of notification.json:

{ "TopicConfigurations": [ { "TopicArn": "arn:aws:sns:us-west-2:123456789012:s3-notification-topic", "Events": [ "s3:ObjectCreated:*" ] } ] }

The SNS topic must have an IAM policy attached to it that allows Amazon S3 to publish to it.

{ "Version": "2008-10-17", "Id": "example-ID", "Statement": [ { "Sid": "example-statement-ID", "Effect": "Allow", "Principal": { "Service": "" }, "Action": [ "SNS:Publish" ], "Resource": "arn:aws:sns:us-west-2:123456789012::s3-notification-topic", "Condition": { "ArnLike": { "aws:SourceArn": "arn:aws:s3:*:*:my-bucket" } } } ] }
