# Amazon SNS code examples for the SDK for Ruby ## Overview Shows how to use the AWS SDK for Ruby to work with Amazon Simple Notification Service (Amazon SNS). *Amazon SNS is a web service that enables applications, end-users, and devices to instantly send and receive notifications from the cloud.* ## ⚠ Important * Running this code might result in charges to your AWS account. * Running the tests might result in charges to your AWS account. * We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see [Grant least privilege](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege). * This code is not tested in every AWS Region. For more information, see [AWS Regional Services](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services). ## Code examples ### Prerequisites For prerequisites, see the [README](../../README.md#Prerequisites) in the `ruby` folder. ### Single actions Code excerpts that show you how to call individual service functions. * [Create a topic](sns-ruby-example-create-topic.rb#L12) (`CreateTopic`) * [List the subscribers of a topic](sns-ruby-example-show-subscriptions.rb#L12) (`ListSubscriptions`) * [List topics](sns-ruby-example-show-topics.rb#L11) (`ListTopics`) * [Publish to a topic](sns-ruby-example-send-message.rb#L13) (`Publish`) * [Set topic attributes](sns-ruby-example-enable-resource.rb#L14) (`SetTopicAttributes`) * [Subscribe an email address to a topic](sns-ruby-example-create-subscription.rb#L13) (`Subscribe`) ## Run the examples ### Instructions The quickest way to interact with this example code is to invoke a [Scenario](#Scenarios) from your command line. For example, `ruby some_scenario.rb` will invoke `some_scenario.rb`. ### Tests ⚠ Running tests might result in charges to your AWS account. To find instructions for running these tests, see the [README](../../README.md#Tests) in the `ruby` folder. ## Contribute Code examples thrive on community contribution. To learn more about the contributing process, see [CONTRIBUTING.md](../../../CONTRIBUTING.md). ## Additional resources * [More Ruby Amazon SNS code examples](https://docs.aws.amazon.com/sdk-for-ruby/v3/developer-guide/ruby_sns_code_examples.html) * [SDK for Ruby Developer Guide](https://aws.amazon.com/developer/language/ruby/) * [SDK for Ruby Amazon SNS Module](https://docs.aws.amazon.com/sdk-for-ruby/v3/api/Aws/SNS.html) * [Amazon SNS Developer Guide](https://docs.aws.amazon.com/sns/latest/dg/welcome.html) * [Amazon SNS API Reference](https://docs.aws.amazon.com/sns/latest/api/welcome.html) --- Copyright Amazon.com, Inc. or its affiliates.
