Glad it worked out.  I should really create a FAQ & Troubleshooting 
document for this sort of thing.  (That's one of those things that I never 
seem to get around to... sigh... whose idea was it to put only 24 hours in 
a day?!)

Yes, I think you're on the right track.  Just a few minor nits:

a) When you add a '?' and parameters to the end of a URL, that's a
     GET request, not a POST request.  If that's REALLY what you want
     to do (and I'm skeptical) then you want to use http_url_get_raw
     instead of post_raw.

b) If you do it as a GET request, the data needs to be encoded and added
     to the URL (see the thread called "Parameters" on this list for
     more info.)

c) If you do it as a POST request, you do not want the '?' at the end of
     the URL.

d) the 'INCOMING' subprocedure is a piece of code that you need to write
      (or copy from my examples). That HTTPAPI will call when data arrives
      on the wire.

You're welcome. Please try to return the favor and help other people who 
ask questions on this mailing list when they have problems. I'm one man. 
As more and more people use this software, it gets harder and harder for 
me to keep up with helping people. Your continued participation in this
