# Amazon SNS raw message delivery
Raw message delivery

To avoid having [Fanout to Firehose delivery streams](sns-firehose-as-subscriber.md), [Amazon SQS](sns-sqs-as-subscriber.md), and [HTTP/S](sns-http-https-endpoint-as-subscriber.md) endpoints process the JSON formatting of messages, Amazon SNS allows raw message delivery:
+ When you enable raw message delivery for 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 Firehose endpoints, the message body is delivered. When you specify message attributes, it won't be sent.

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

## Message format examples


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.

## Message attributes and raw message delivery for Amazon SQS subscriptions


Amazon SNS supports the delivery of message attributes, which allow you to provide structured metadata items, such as timestamps, geospatial data, signatures, and identifiers, about the message. For Amazon SQS subscriptions with **Raw Message Delivery** enabled, a maximum of 10 message attributes can be sent. To send more than 10 message attributes, you must disable Raw Message Delivery. However, Amazon SNS discards messages with more than 10 message attributes directed towards Amazon SQS subscriptions with Raw Message Delivery enabled, treating them as client-side errors.
