What can the Webhooks API trigger upon certain events?

The Webhooks API in Tableau is designed to facilitate real-time communication by sending notifications to external systems when specific events occur within Tableau Server. This functionality is vital for automating workflows and integrating Tableau with other applications.

The correct answer emphasizes that the Webhooks API can issue HTTP POST notifications. When an event occurs—such as a data refresh completion or an update to a view—a webhook can be configured to send an HTTP POST request to a designated endpoint. This allows organizations to respond to these events dynamically, enabling processes like sending alerts, logging information, or triggering additional workflows in other systems.

The other choices refer to important activities within Tableau, but they do not accurately describe the primary purpose of the Webhooks API. Data refresh alerts and visualization renders pertain more to the processes and outputs within Tableau rather than the mechanism of sending notifications. Similarly, while data extraction processes are a crucial part of data management in Tableau, they do not directly relate to the functionality of the Webhooks API that is focused on external communication through notifications.
