What is Keyed-Hashing for Message Authentication (HMAC)?
HMAC (Hashed Message Authentication Code) is the authentication mechanism used for BusinessData services.
To ensure that you are a genuine customer, you will be required to authenticate yourself when submitting any BusinessData transactions. To do this, you will need to include a digital signature which we can use to verify your identity.
HMAC is a software token authentication mechanism defined in RFC2104 HMAC: Keyed-Hashing for Message Authentication.
All BusinessData web services use HMAC authentication. Please refer to the specific web service contract models on how to implement the HMAC authentication in to your request files.
