What are Webhooks? A webhook is an HTTP request that is triggered by an event in one system and automatically sent to another system. It can often include a payload of data. Here one system that is the source speaks by sending an HTTP request to another system that is the destination. The information about the event called request payload is shared. Streaming service is an example of Webook. Webhooks are also called Web Pullbacks and HTTP Push APIs. https://store.outrightcrm.com/blog/what-are-webhooks/
