Sam: Thanks for the link to the source Jon: I didn't include an example in my original post because the call is for obtaining an authorization token from a private server which made it awkward to share. But, thanks to your example, I pursued coming up with a good example and managed to get my original snippet working. I've pasted the example with the test server I used below. I found this server (httpbin.org) helpful because it echos the data element that it received -- this enabled me to sort out my typos...

[racket-users] Re: raco pkg migrate previous versions
If you're running Linux or (I assume) OS X, I think you might be able to just do the following: $ ls ~/.racket For me, that shows folders for Racket versions that include raco pkg install packages. Maybe that's sufficient?
