# Get Component Instance

[Catalyst Data Streams](https://docs.catalyst.zoho.com/en/cloud-scale/help/data-streams/introduction/) lets you publish live, event-based data through channels and deliver it instantly to subscribed clients. You can create an instance of the Data Streams component to access all channel-level operations such as listing channels, publishing data, and generating WebSocket tokens.

You must first create a Data Streams instance using the `datastreams()` method to perform any Data Streams operations. The `initialize_app()` method requires valid Catalyst credentials and app options from credential file or environment variables.

```python
import zcatalyst_sdk
# Initialize SDK (reads credentials + project options)
app_sdk = zcatalyst_sdk.initialize_app()
# Get the Datastreams component
data_streams = app_sdk.datastreams()
```
