SnsMessage stores information about each record of a SNS event

Fields

sns_message_type: String

The type of SNS message. For a lambda event, this should always be Notification

message_id: String

A Universally Unique Identifier, unique for each message published. For a notification that Amazon SNS resends during a retry, the message ID of the original message is used.

topic_arn: String

The Amazon Resource Name (ARN) for the topic that this message was published to.

subject: Option<String>

The Subject parameter specified when the notification was published to the topic.

The SNS Developer Guide states: This is an optional parameter. If no Subject was specified, then this name-value pair does not appear in this JSON document.

Preliminary tests show this appears in the lambda event JSON as Subject: null, marking as Option with need to test additional scenarios

timestamp: DateTime<Utc>

The time (UTC) when the notification was published.

signature_version: String

Version of the Amazon SNS signature used.

signature: String

Base64-encoded SHA1withRSA signature of the Message, MessageId, Subject (if present), Type, Timestamp, and TopicArn values.

signing_cert_url: String

The URL to the certificate that was used to sign the message.

unsubscribe_url: String

A URL that you can use to unsubscribe the endpoint from this topic. If you visit this URL, Amazon SNS unsubscribes the endpoint and stops sending notifications to this endpoint.

message: String

The Message value specified when the notification was published to the topic.

message_attributes: HashMap<String, MessageAttribute>

This is a HashMap of defined attributes for a message. Additional details can be found in the SNS Developer Guide
