Q: What is the format of structured notification messages sent by Amazon SNS?

The notification message sent by Amazon SNS for deliveries over HTTP, HTTPS, Email-JSON and SQS transport protocols will consist of a simple JSON object, which will include the following information:

MessageId: A Universally Unique Identifier, unique for each notification published.
Timestamp: The time (in GMT) at which the notification was published.
TopicArn: The topic to which this message was published
Type: The type of the delivery message, set to “Notification” for notification deliveries.
UnsubscribeURL: A link to unsubscribe the end-point from this topic, and prevent receiving any further notifications.
Message: The payload (body) of the message, as received from the publisher.
Subject: The Subject field – if one was included as an optional parameter to the publish API call along with the message.
Signature: Base64-encoded “SHA1withRSA” signature of the Message, MessageId, Subject (if present), Type, Timestamp, and Topic values.
SignatureVersion: Version of the Amazon SNS signature used.
Notification messages sent over the “Email” transport only contain the payload (message body) as received from the publisher.
