title: How to pass through Jenkins credentials?
body: <p>I'm trying to follow the advice given in <a href="https://stackoverflow.com/questions/4870187/set-hudson-build-description-via-web-api">Set Hudson Build Description via Web API</a> but I'm getting a 403 presumably because the request has to be authenticated. Since the script is being run from an authenticated Jenkins session, how do I pass those credentials through?</p>
