Webhook
A webhook is a method that provides real-time information to other applications, triggering an action when a specific event occurs.
Definition
A webhook, in simple terms, is a method used to provide other applications with real-time information. It is a kind of reverse API that sends data to other applications immediately when a certain event occurs, rather than requiring the application to request data back. Webhooks are also known as HTTP(S) callbacks or push APIs.
Usage and Context
Webhooks are used to facilitate communication between two applications or servers. They are typically used when the real-time notification of an event is required. For example, a webhook can be set up to notify a user when a new post has been published on a blog, or when a payment has been successfully processed on an e-commerce site. Webhooks are also used in the automation of workflows, where an event in one application triggers an action in another.
