How can I use the boto library in Python programming language for the Integration of S3 and SNS?

 In the context of AWS, you can achieve this objective of Integration between S3 and SNS by using the boto library in Python programming language by using simple steps which are given below:-

Create an SNS topic

First, try to create an SNS topic by using boto where notification would be sent:-

Import boto3

# Create an SNS client

Sns_client = boto3.client(‘sns’)

# Create a new SNS topic

Response = sns_client.create_topic(Name=’S3_File_Uploads’)

# Get the ARN (Amazon Resource Name) of the created topic

Topic_arn = response[‘TopicArn’]

Subscribe administration to the topic

You would need to subscribe to administrators' email addresses or Phone numbers to the SNS topic so that they can receive the notification:-

# Subscribe administrators to the SNS topic

Sns_client.subscribe(

    TopicArn=topic_arn,

    Protocol=’email’,  # or ‘sms’ for phone numbers

    Endpoint=’admin@example.com’  # Replace with the administrator’s email address or phone number

)

Configuration of S3 bucket notification

You would need to configure the S3 bucket to send notifications to the SNS topic whenever a new file is uploaded:-

# Create an S3 client

S3_client = boto3.client(‘s3’)

# Configure S3 bucket notifications

S3_client.put_bucket_notification_configuration(

    Bucket=’your_bucket_name’,

    NotificationConfiguration={

        ‘TopicConfigurations’: [

            {

                ‘TopicArn’: topic_arn,

                ‘Events’: [‘s3:ObjectCreated:*’]

            }

        ]

    }

)
