For the SubmitFeed (p. 41) function, we require that you pass the Content-MD5 HTTP header, which contains the MD5 hash of the HTTP entity body (see Section 14.15 of RFC 2616, the HTTP/1.1 specification), so we can check if the feed we stored for processing is bit for bit identical with what you sent, protecting you from corrupted descriptive or pricing product data appearing on Amazon.com.
