This is going to be a royal pain to do in the shell. You're going to get stuck waiting on input from the web service while the web browser is stuck waiting on input for you. Named pipes are prone to this, even used one-way -- using a pair means almost guaranteed deadlock.

If you have Python or Perl, I'd look into writing it in that language instead. You would use a socket directly, avoiding the need for these deadlocks.

Another alternative, which I know you didn't want, would be the expect language. It can work pretty much the way you were expecting - run a program, check if it's got input, check if it's got output, decide what do do with it, move on.
