Logging Amazon SNS API calls using CloudTrail - Amazon Simple Notification Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Logging Amazon SNS API calls using CloudTrail

Amazon SNS is integrated with Amazon CloudTrail, a service that provides a record of actions taken by a user, role, or an Amazon service in Amazon SNS. CloudTrail captures API calls for Amazon SNS as events. The calls captured include calls from the Amazon SNS console and code calls to the Amazon SNS API operations. If you create a trail, you can enable continuous delivery of CloudTrail events to an Amazon S3 bucket, including events for Amazon SNS. If you don't configure a trail, you can still view the most recent events in the CloudTrail console in Event history. Using the information collected by CloudTrail, you can determine the request that was made to Amazon SNS, the IP address from which the request was made, who made the request, when it was made, and additional details.

To learn more about CloudTrail, including how to configure and enable it, see the Amazon CloudTrail User Guide.

Amazon SNS information in CloudTrail

CloudTrail is enabled on your Amazon Web Services account when you create the account. When supported event activity occurs in Amazon SNS, that activity is recorded in a CloudTrail event along with other Amazon service events in Event history. You can view, search, and download recent events in your Amazon Web Services account. For more information, see Viewing Events with CloudTrail Event History.

For an ongoing record of events in your Amazon Web Services account, including events for Amazon SNS, create a trail. A trail enables CloudTrail to deliver log files to an Amazon S3 bucket. By default, when you create a trail in the console, the trail applies to all Amazon Regions. The trail logs events from all Regions in the Amazon partition and delivers the log files to the Amazon S3 bucket that you specify. Additionally, you can configure other Amazon services to further analyze and act upon the event data collected in CloudTrail logs. For more information, see the following:

Amazon SNS supports logging the following actions as events in CloudTrail log files:


When you are not logged in to Amazon Web Services (unauthenticated mode) and either the ConfirmSubscription or Unsubscribe actions are invoked, then they will not be logged to CloudTrail. Such as, when you choose the provided link in an email notification to confirm a pending subscription to a topic, the ConfirmSubscription action is invoked in unauthenticated mode. In this example, the ConfirmSubscription action would not be logged to CloudTrail.

Every event or log entry contains information about who generated the request. The identity information helps you determine the following:

  • Whether the request was made with root or Amazon Identity and Access Management (IAM) user credentials.

  • Whether the request was made with temporary security credentials for a role or federated user.

  • Whether the request was made by another Amazon service.

For more information, see the CloudTrail userIdentity Element.

Example: Amazon SNS log file entries

A trail is a configuration that enables delivery of events as log files to an Amazon S3 bucket that you specify. CloudTrail log files contain one or more log entries. An event represents a single request from any source and includes information about the requested action, the date and time of the action, request parameters, and so on. CloudTrail log files aren't an ordered stack trace of the public API calls, so they don't appear in any specific order.

The following example shows a CloudTrail log entry that demonstrates the ListTopics, CreateTopic, and DeleteTopic actions.
