I used curl to request the crumb and the session ID and then passed that crumb and session ID to a later curl call which performed the work I needed to do.
Refer to https://github.com/MarkEWaite/jenkins-bugs/blob/6db4ea8ef277dbe496346d8ceaebdb12029d870c/reportScanLogResults#L56 for the "cookie jar" that remembers the session ID. Refer to https://github.com/MarkEWaite/jenkins-bugs/blob/6db4ea8ef277dbe496346d8ceaebdb12029d870c/reportScanLogResults#L89 for a use of that "cookie jar". I think the topic of API use (including cookie use and various alternatives to call the API) deserves a future topic for a "How-To Guide" to be added to https://jenkins.io/doc/developer/guides/ .
