Webhooks are also called "reverse APIs". They provide a mechanism where server-side applications can notify the client when a new event occurs on the server. webhooks operate on the concept of "event reaction" (don't call me, I'll call you if I have something new).
Webhooks let one system keep another up to date in real time. Apps can use webhooks to trigger something like a text message, an email, a data export, or even a synchronisation. The data is sent across the web using secure HTTPS. It's both quick and reliable.
- A way to communicate between web applications.
- Sending real-time data.
- Automated, instant, and real-time notifications.

Tools and Resources
Debugging a webhook can be complex at times, as webhooks are principally asynchronous. Thus, you must trigger them and wait, then check the response. Following are the tools to build and test a webhook workflow:
- Webhook’s requests can be collected and seen by using a tool like RequestBin.
- Mock or produce requests using a tool like cURL or Postman.
