Actions in web applications are known as events. What Webhooks do is allow you to send event data to another application, automatically. For example, let's say you just generated an invoice using StaffConnect's payroll feature. You can set up Webhooks to gather all of that event information and send that directly into Quickbooks, meaning you don't have to then generate another invoice there! The beautiful thing? It works with any web application that also supports RESTful API's!
