Re: REST request to Vertex Cloud

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

Ron,

I am not familiar with 'Vertex Cloud' and hadn't heard of it prior to 
your post.

The data you're sending is a JSON document, so the correct content-type 
would be 'application/json'.  You say that gives you a 415 response, 
which makes me think I'm missing something in how this is supposed to work.

You say you tried 'x-www-form-urlencoded' but that is not a valid media 
type at all.  You probably meant 'application/x-www-form-urlencoded', 
which is the default media type for HTML form data.  (However, your JSON 
document is not HTML form data, at least not the way you've coded it.)

If you can tell me how you're supposed to send it, I could tell you how 
to do it in HTTPAPI.  But, I can't figure it out from the info you've 
supplied.
