Payload Hashing

If the destination endpoint requires a hash of the payload to verify authenticity, you may generate the hash value by constructing your detokenize payload and posting it to the payload hashing endpoint. This endpoint will detokenize the payload, perform any other processing, then hash the payload in its entirety using the hashing algorithm specified in the 'Type' query string parameter. Acceptable Type values are:

MD5
SHA1
SHA256
SHA384
SHA512

The payload hashing endpoint also supports the HMAC variants of the above algorithms:

HMACMD5
HMACSHA1
HMACSHA256
HMACSHA384
HMACSHA512

To perform Hashing using HMAC key, the tx-HMACkey header must be supplied and its value must be in base64 encoded format.

The resulting hash will be returned in the body of the Response.
