TL:DR
I found a great #webtool for exploring HTTP Requests: https://requestcatcher.com

I'm working on a pet project currently which may or may not turn into something real. I am having a hard time making the Twilio validator work behind AWS API Gateway in my Lambda function, so I want to catch the original HTTP POST. This tool makes it SO easy!

If you want to catch a #webhook without having to setup your own http server to catch it, this is great!
