# Use `PutBucketNotification` with a CLI
<a name="s3_example_s3_PutBucketNotification_section"></a>

The following code examples show how to use `PutBucketNotification`.

------
#### [ CLI ]

**AWS CLI**  
The applies a notification configuration to a bucket named `amzn-s3-demo-bucket`:  

```
aws s3api put-bucket-notification --bucket amzn-s3-demo-bucket --notification-configuration file://notification.json
```
The file `notification.json` is a JSON document in the current folder that specifies an SNS topic and an event type to monitor:  

```
{
  "TopicConfiguration": {
    "Event": "s3:ObjectCreated:*",
    "Topic": "arn:aws:sns:us-west-2:123456789012:s3-notification-topic"
  }
}
```
The SNS topic must have an IAM policy attached to it that allows Amazon S3 to publish to it:  

```
{
 "Version":"2012-10-17",		 	 	 
 "Id": "example-ID",
 "Statement": [
  {
   "Sid": "example-statement-ID",
   "Effect": "Allow",
   "Principal": {
     "Service": "s3.amazonaws.com"
   },
   "Action": [
    "SNS:Publish"
   ],
   "Resource": "arn:aws:sns:us-west-2:123456789012:amzn-s3-demo-bucket",
   "Condition": {
      "ArnLike": {
      "aws:SourceArn": "arn:aws:s3:*:*:amzn-s3-demo-bucket"
    }
   }
  }
 ]
}
```
+  For API details, see [PutBucketNotification](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/s3api/put-bucket-notification.html) in *AWS CLI Command Reference*.

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: This example configures the SNS topic configuration for the S3 event ObjectRemovedDelete and enables notification for the given s3 bucket**  

```
$topic =  [Amazon.S3.Model.TopicConfiguration] @{
  Id = "delete-event"
  Topic = "arn:aws:sns:eu-west-1:123456789012:topic-1"
  Event = [Amazon.S3.EventType]::ObjectRemovedDelete
}

Write-S3BucketNotification -BucketName amzn-s3-demo-bucket -TopicConfiguration $topic
```
**Example 2: This example enables notifications of ObjectCreatedAll for the given bucket sending it to Lambda function.**  

```
$lambdaConfig = [Amazon.S3.Model.LambdaFunctionConfiguration] @{
  Events = "s3:ObjectCreated:*"
  FunctionArn = "arn:aws:lambda:eu-west-1:123456789012:function:rdplock"
  Id = "ObjectCreated-Lambda"
  Filter = @{
    S3KeyFilter = @{
      FilterRules = @(
        @{Name="Prefix";Value="dada"}
        @{Name="Suffix";Value=".pem"}
      )
    }
  }
}

Write-S3BucketNotification -BucketName amzn-s3-demo-bucket -LambdaFunctionConfiguration $lambdaConfig
```
**Example 3: This example creates 2 different Lambda configuration on the basis of different key-suffix and configured both in a single command. **  

```
#Lambda Config 1

$firstLambdaConfig = [Amazon.S3.Model.LambdaFunctionConfiguration] @{
  Events = "s3:ObjectCreated:*"
  FunctionArn = "arn:aws:lambda:eu-west-1:123456789012:function:verifynet"
  Id = "ObjectCreated-dada-ps1"
  Filter = @{
    S3KeyFilter = @{
      FilterRules = @(
        @{Name="Prefix";Value="dada"}
        @{Name="Suffix";Value=".ps1"}
      )
    }
  }
}

#Lambda Config 2

$secondlambdaConfig = [Amazon.S3.Model.LambdaFunctionConfiguration] @{
  Events = [Amazon.S3.EventType]::ObjectCreatedAll
  FunctionArn = "arn:aws:lambda:eu-west-1:123456789012:function:verifyssm"
  Id = "ObjectCreated-dada-json"
  Filter = @{
    S3KeyFilter = @{
      FilterRules = @(
        @{Name="Prefix";Value="dada"}
        @{Name="Suffix";Value=".json"}
      )
    }
  }
}

Write-S3BucketNotification -BucketName amzn-s3-demo-bucket -LambdaFunctionConfiguration $firstLambdaConfig,$secondlambdaConfig
```
