Any help would be appreciated. If you need to support clients who have out-of-sync clocks, you can Firstly, sometimes clients do provide a nonce in digest auth, but mainly it relies on the server (see RFC2617) Secondly, because if you think of the authentication procedure in terms of a handshake, then with Oauth when you already have a token you've been through half of the handshake, you've already spoken with the server, so your next move is to contact the server As far as I can see all the parameters that I have added are correct (Url, consumer_key, consumer_secret, nonce, timestamp, HMAC-SHA1) but Postman just seems to generate a different signature with these details. 20.
