Hello,
After having read through the security page and the various posts in dev forum, I am no where close to what I need to get a properly authenticated request/response.
My understanding of the Authorisation setup is that:
1. requires keyID in the header.
2. requires a header field called signature containing the secret and the base64encoded SHA1 has of the key.
I know I am missing something but needed an answer which is implementation language agnostic as we are not using any generic language but a different application to call the API.
Easiest way would be if I could get this working from SOAP UI, that will give me an idea on its implementation in my application.
