What are Webhooks?
Webhooks are simple HTTP callbacks. They’re a way for third-party services to send data to other services. They're a simple, lightweight alternative to REST APIs, and they can be used to create powerful integrations between different systems.
The term webhooks was coined by Jeff Lindsay in 2007 from the computer programming term “hook.” They're used by many major companies like MailChimp and Shopify today. They work by sending an HTTP POST request to a specified URL when something happens in your application.
