Webhook: is a way for an application to provide other applications with real-time information. Instead of applications constantly asking ("polling") for updates, a webhook "pushes" data when a specific event occurs.

Event-Driven: Webhooks are triggered by specific events. For example, a new order placed on an e-commerce website, or a new message posted in a chat application.

Real-Time Data: When an event happens, the application automatically sends data to a specified URL (the "webhook URL"). This allows other applications to receive and process the information instantly.

"Push" Mechanism: Unlike traditional APIs where applications "pull" data, webhooks "push" data. This means the sending application initiates the communication, rather than the receiving application.

How it works: Basically a webhook makes an HTTP request. So when an event occurs, the server of the application that the event happened on, makes an HTTP request to the preconfigured URL of the application that is going to receive the information.

Here are some key benefits of using webhooks:

• Automation: Webhooks automate workflows by enabling applications to react to events in real-time.
• Efficiency: They eliminate the need for constant polling, which saves server resources and reduces latency.
• Real-time updates: They provide up to the minute data.
