Webhooks are event-driven mechanisms that allow one system to send real-time data to another when specific events occur. In a streaming ETL (Extract, Transform, Load) workflow, webhooks act as a reliable source or destination for delivering or receiving data instantaneously. Their simplicity and flexibility make them a powerful tool for integrating systems and triggering real-time data transformations.

1. Create a new source within ProxyHook and select 'Webhooks'. Grab the unique endpoint provided.
