Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

CloudWatchLogsLogGroupArn

Specifies a log group name using an Amazon Resource Name (ARN), a unique identifier that represents the log group to which CloudTrail logs will be delivered. You must use a log group that exists in your account.

Not required unless you specify CloudWatchLogsRoleArn.

Type: String

Required: No

CloudWatchLogsRoleArn

Specifies the role for the CloudWatch Logs endpoint to assume to write to a user's log group. You must use a role that exists in your account.

Type: String

Required: No

EnableLogFileValidation

Specifies whether log file integrity validation is enabled. The default is false.

Note

When you disable log file integrity validation, the chain of digest files is broken after one hour. CloudTrail does not create digest files for log files that were delivered during a period in which log file integrity validation was disabled. For example, if you enable log file integrity validation at noon on January 1, disable it at noon on January 2, and re-enable it at noon on January 10, digest files will not be created for the log files delivered from noon on January 2 to noon on January 10. The same applies whenever you stop CloudTrail logging or delete a trail.

Type: Boolean

Required: No

IncludeGlobalServiceEvents

Specifies whether the trail is publishing events from global services such as IAM to the log files.

Type: Boolean

Required: No

IsMultiRegionTrail

Specifies whether the trail is created in the current Region or in all Regions. The default is false, which creates a trail only in the Region where you are signed in. As a best practice, consider creating trails that log events in all Regions.

Type: Boolean

Required: No

IsOrganizationTrail

Specifies whether the trail is created for all accounts in an organization in AWS Organizations, or only for the current AWS account. The default is false, and cannot be true unless the call is made on behalf of an AWS account that is the management account or delegated administrator account for an organization in AWS Organizations.

Type: Boolean

Required: No

KmsKeyId

Specifies the AWS KMS key ID to use to encrypt the logs delivered by CloudTrail. The value can be an alias name prefixed by alias/, a fully specified ARN to an alias, a fully specified ARN to a key, or a globally unique identifier.

CloudTrail also supports AWS KMS multi-Region keys. For more information about multi-Region keys, see Using multi-Region keys in the AWS Key Management Service Developer Guide.

Examples:

  • alias/MyAliasName

  • arn:aws:kms:us-east-2:123456789012:alias/MyAliasName

  • arn:aws:kms:us-east-2:123456789012:key/12345678-1234-1234-1234-123456789012

  • 12345678-1234-1234-1234-123456789012

Type: String

  • Contain only ASCII letters (a-z, A-Z), numbers (0-9), periods (.), underscores (_), or dashes (-)

  • Start with a letter or number, and end with a letter or number

  • Be between 3 and 128 characters

  • Have no adjacent periods, underscores or dashes. Names like my-_namespace and my--namespace are not valid.

  • Not be in IP address format (for example, 192.168.5.4)

Type: String

Required: Yes

S3BucketName

Specifies the name of the Amazon S3 bucket designated for publishing log files. For information about bucket naming rules, see Bucket naming rules in the Amazon Simple Storage Service User Guide.

Type: String

Required: Yes

S3KeyPrefix

Specifies the Amazon S3 key prefix that comes after the name of the bucket you have designated for log file delivery. For more information, see Finding Your CloudTrail Log Files. The maximum length is 200 characters.

Required: No

SnsTopicName

Specifies the name of the Amazon SNS topic defined for notification of log file delivery. The maximum length is 256 characters.

Type: String
