Amazon SNS is a web service that enables you to build distributed web-enabled applications. Applications can use Amazon SNS to easily push real-time notification messages to interested subscribers over multiple delivery protocols. For more information about this product see the [Amazon SNS product page](https://aws.amazon.com/sns/). For detailed information about Amazon SNS features and their associated API calls, see the [Amazon SNS Developer Guide](https://docs.aws.amazon.com/sns/latest/dg/).

We also provide SDKs that enable you to access Amazon SNS from your preferred programming language. The SDKs contain functionality that automatically takes care of tasks such as: cryptographically signing your service requests, retrying requests, and handling error responses.
