According to the web search results, WebSocket and Webhook are two Mist-supported APIs that are considered event-driven. Event-driven APIs are APIs that allow the server to push information to the client asynchronously, instead of requiring the client to poll the server for updates. Event-driven APIs can provide real-time data, decoupled systems, and improved scalability and performance.

WebSocket is a protocol that enables bidirectional communication between a client and a server over a single TCP connection1.WebSocket allows the server to send messages to the client without waiting for a request, and vice versa1.WebSocket can be used for event-driven APIs that require continuous and interactive data exchange, such as chat applications, online games, or live streaming1.

Webhook is a way of sending data from the server to a third-party application or service when a certain event occurs2.Webhook allows the server to notify the client about an event, such as a new order, a payment confirmation, or a user registration2.Webhook can be used for event-driven APIs that require one-way notifications or integrations with other platforms, such as Slack, Splunk, or ServiceNow2.
