How to test WinHTTP POST locally

I have a requirement to send some data to a 3rd party listener via POST. I've written a database trigger to send via WinHTTP but I've never done this before. How can I set up a POST listener and send to myself? I'm thinking I could use 127.0.0.1 as the IP but am not sure how to go about it? Ideally I'd like a browser to wait for the input then wri开发者_StackOverflow社区te it out.

Found an answer myself, thanks to Henry Cipolla's blog, he has set up www.posttestserver.com that one can test their POSTs at.
