My name is Dylan Vester and I'm the founder of Subroute.io (https://subroute.io) an free online IDE to create unlimited Webhooks and Microservices with .NET. At Subroute.io you can create a Webhook that notifies you via Twitter when an issue is posted to your GitHub project. You could also create a Webhook that sends out a thank you email when you receive a payment or donation via PayPal. With the full power of the .NET framework at your disposal, you'll have all the tools you need to create whatever type of API you need.
