# Socket IO

### Overview

The Socket.io trigger allows a flow to listen to events in one or more configured socket.io rooms. If a socket.io client sends an event to one of the rooms, flow execution starts. Like the [REST](https://cxfabric.gitbook.io/docs/developer-tools/components/triggers/rest)/[Webhook](https://cxfabric.gitbook.io/docs/developer-tools/components/triggers/web-hook) trigger, the socket.io trigger is associated with an automatically generated endpoint URL for this flow.
