A webhook is a tool that allows two different software applications to communicate with each other. Essentially, a webhook is a way for an application to automatically send information to another application when something specific happens.

For example, if you run an online store, you might use a webhook to automatically send customer data to your accounting software whenever a purchase is made. This can save you time and effort, as you won't have to manually enter data into your accounting system.

Webhooks are becoming increasingly popular as more and more businesses rely on complex software solutions to manage their operations. With a webhook, you can make sure that all your different software applications stay in sync and work together seamlessly.
