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.

• Real-Time Data Extraction: Use webhooks as a source to capture event data, such as user actions or system changes, and feed it into ETL pipelines.
• Trigger-Based Processing: Initiate ETL workflows upon receiving webhook events, enabling on-demand data transformation and loading.
• Data Delivery to Applications: Send transformed data from ETL pipelines to webhooks for integration with external systems or applications.
• Automation and Notifications: Deliver processed data or alerts to connected services via webhooks for immediate action or monitoring.
