Announcing ASP.NET WebHooks Release Candidate 1

For example, you can subscribe to receive a WebHook when someone sends money to your PayPal account, or when a message is posted to Slack, or a picture is posted to Instagram – the opportunities are endless! When subscribing, you provide a callback URI where you want to be notified. When an event occurs in the service you subscribe to, a WebHook is sent to your callback URI with information about what happened so that your Web Application can process it accordingly. WebHooks happen without polling and with no need to hold open a network connection while waiting for event notifications.
