Publish Data

# Publish Data

Catalyst Data Streams enables you to publish real-time data to a channel. Any active subscribers connected to that channel will receive the published data instantly through their WebSocket connections.

You can publish data to a channel by passing the channel ID and the data payload to the publish_data() method. The data_streams reference used below is the component instance created earlier. To know more about this instance, please refer to this section.
