Has anyone delt with creating Virtual Services that require OAuth 1.0 in order to record them in devtest 10.1? There doesn't seem to be much documentation on using OAuth. I have been trying to build a models that would handle the 3 part handshake necessary to use devtest, but I am continually being told that when sending a request to an OAuth 1.0 server from devtest, the signature is invalid. We are using HMACSHA256 to encode the signature.
