First, egads, sorry that you're having trouble. It appears from the
code snippet and what you describe that the main difference between
the calls that work and don't (from the browser and from your code)
are GET vs. POST. This leads me to believe that this is a bug we
introduced on our end.
We recently were facing some performance issues, so enabled caching
for calls where that makes sense. I'm sure details was one of those
(since when doing a GET, the result is the same no matter what). I
suspect that for some reason the POST payload isn't making it through.
Nathan Kinkade (cc'd), can you look at the Varnish configuration and
make sure POST calls to the API are getting passed through directly to
