aws-cdk.aws-sns-subscriptions

What it is and what it does

This package is a CDK construct library for AWS SNS topic subscriptions. It provides Python classes that wrap SNS subscription logic, allowing you to attach SNS topics to multiple endpoint types—SQS queues, Lambda functions, email addresses, SMS numbers, and HTTPS URLs—using a simple `.add_subscription()` method call on a topic object.

The library handles common setup tasks like automatically granting KMS key permissions when subscribing encrypted queues, and supports CloudFormation parameters for dynamic endpoint values. However, the package is part of AWS CDK v1, which reached end-of-support on 2023-06-01; AWS recommends migrating to AWS CDK v2 for ongoing support and updates.

Use it for:

• Route SNS notifications to SQS queues for asynchronous processing and decoupling from Lambda.
• Trigger Lambda functions directly from SNS topic events without manual permission setup.
• Send email notifications to subscribers by adding email subscriptions to an SNS topic.
• Deliver SMS alerts to phone numbers via SNS topic subscriptions.
• Subscribe HTTPS endpoints to receive SNS messages as webhook POST requests.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides AWS CDK constructs for subscribing SNS topics to endpoints including SQS queues, Lambda functions, email addresses, SMS numbers, and HTTPS URLs.

No—this is AWS CDK v1, which reached end-of-support on 2023-06-01 and is no longer being updated. While the package itself has low install friction and permissive licensing, AWS explicitly recommends migrating to AWS CDK v2. Install only if you are maintaining legacy CDK v1 infrastructure; for new projects, use the v2 equivalent instead.

Install

pip install aws-cdk-aws-sns-subscriptions

uv add aws-cdk-aws-sns-subscriptions

poetry add aws-cdk-aws-sns-subscriptions

Installing aws-cdk.aws-sns-subscriptions

Before you install

Low install friction with a wheel distribution. However, this is AWS CDK v1, which reached end-of-support on 2023-06-01 and is no longer being updated; users should migrate to AWS CDK v2 instead.

License in practice

Licensed under Apache-2.0 (permissive), allowing commercial use, modification, and distribution with minimal restrictions.

Quickstart

from aws_cdk import aws_sns as sns
from aws_cdk.aws_sns_subscriptions import SqsSubscription, LambdaSubscription

topic = sns.Topic(self, "MyTopic")
topic.add_subscription(SqsSubscription(my_queue))
topic.add_subscription(LambdaSubscription(my_function))

Requires AWS CDK v1 environment; AWS CDK v1 is end-of-support as of 2023-06-01 and migration to v2 is recommended.

Verify before relying

• Whether cross-region SQS and Lambda subscriptions work reliably in all AWS regions.
• Current state of KMS key permission grants for encrypted queue subscriptions.
• Whether email and SMS subscriptions require additional AWS account configuration beyond token resolution.
