A Webhook is a mechanism that allows applications to communicate in real-time by sending HTTP POST requests when specific events occur. It serves as a callback or notification mechanism, enabling seamless integration and automation of processes across different systems.

When an event triggers a webhook, the associated payload containing relevant data is sent to a predefined URL endpoint, typically provided by the receiving application. This payload contains information about the event that occurred, allowing the recipient to process and respond accordingly.

Webhooks find widespread use in various scenarios, including triggering notifications, updating data, or synchronizing systems. They provide a flexible and efficient way for applications to react to events and maintain real-time communication, enhancing workflow automation and system interoperability.
