  version: '2010-03-31'
  description: Amazon Simple Notification Service (SNS) is a fully managed pub/sub messaging service that enables application-to-application (A2A) and application-to-person (A2P) communication. SNS allows you to create topics, manage subscriptions, and publish messages to subscribers via multiple protocols including HTTP/S, email, SMS, SQS, Lambda, and mobile push. This specification models the SNS query API actions as RESTful paths for topic management, subscription lifecycle, and message publishing operations.
