What's a Webhook?

By
 A webhook is an API concept that's growing in popularity. As more and more of what we do on the web can be described by events, webhooks are becoming even more applicable. They're incredibly useful and a resource-light way to implement event reactions. So, what exactly is a webhook? A webhook is a way for an app to provide other application with real-time information. A webhook delivers data to other application as it happens, meaning you get data immediately. Unlike typical APIs where you would need to poll for data very frequently in order to get it real-time. This makes webhooks much more efficient for both provider and  consumer. The only drawback to webhooks is the difficulty of initially setting them up. Webhooks are sometimes referred to as "Reverse APIs," as they give you what amounts to an API spec, and you must design and API for the werbhook to use. The webhook will make an HTTP request to your app and you will then be charged with interpreting it.

The concept of a package manager might be familiar to you if you are coming from other languages. JavaScript uses npm for package management, Ruby uses gem, and .NET use NuGet. In Python, pip has become the standard package manager. The Python installer installs pip, so it should be ready for you to use, unless you installed an old version of Python. You can verify that pip is available by running the following command in your console:
