Request signatures

All outgoing HTTP requests has the User-Agent header set to Serialized/1.0 and includes a Serialized specific signature header that can be used to verify the request’s authenticity.
The header is named Serialized-Request-Signature and contains a HMAC calculated using the HmacSHA256 algorithm, specified in RFC 2104 and FIPS PUB 180-2.
Different request types
Different requests have different signatures, that you can use to verify the outgoing request from Serialized to your backend.

      String calculatedSignature = new HmacUtils(HMAC_SHA_256, expectedReactionName).hmacHex(body);
