What is Webhook?

A webhook is a way for an application to notify another application when a specific event occurs. It’s a way for two applications to communicate with each other in real-time. When the event happens, the application sends a message to a predefined URL (the webhook) with the relevant data. The receiving application can then use this data to take action, such as updating a database or triggering another event. Webhooks are often used in integrations between different software systems and can be a more efficient way to pass information between applications than traditional APIs.
