Amazon SNS raw message delivery

To avoid having Amazon Kinesis Data Firehose, Amazon SQS, and HTTP/S endpoints process the JSON formatting of messages, Amazon SNS allows raw message delivery:

  • When you enable raw message delivery for Amazon Kinesis Data Firehose or Amazon SQS endpoints, any Amazon SNS metadata is stripped from the published message and the message is sent as is.

  • When you enable raw message delivery for HTTP/S endpoints, the HTTP header x-amz-sns-rawdelivery with its value set to true is added to the message, indicating that the message has been published without JSON formatting.

  • When you enable raw message delivery for HTTP/S endpoints, the message body, client IP, and the required headers are delivered. When you specify message attributes, it won't be sent.

  • When you enable raw message delivery for Kinesis Data Firehose endpoints, the message body is delivered. When you specify message attributes, it won't be sent.

To enable raw message delivery using an Amazon SDK, you must use the SetSubscriptionAttribute API action and set the value of the RawMessageDelivery attribute to true.

Enabling raw message delivery using the Amazon Web Services Management Console

  1. Sign in to the Amazon SNS console.

  2. On the navigation panel, choose Topics.

  3. On the Topics page, choose a topic subscribed to an Kinesis Data Firehose, Amazon SQS, or HTTP/S endpoint.

  4. On the MyTopic page, in the Subscription section, choose a subscription and choose Edit.

  5. On the Edit EXAMPLE1-23bc-4567-d890-ef12g3hij456 page, in the Details section, choose Enable raw message delivery.

  6. Choose Save changes.

In the following examples, the same message is sent to the same Amazon SQS queue twice. The only difference is that raw message delivery is disabled for the first message, and enabled for the second.
