Create a Channel

To create a new Data Streams channel:

1. Access Data Streams from the service menu under Cloud Scale.
   

2. Click the Create Channel button.
   

3. Enter a descriptive name for your channel (e.g., “user-notifications”, “order-updates”, “live-chat”).
   

4. Select an access control type to determine how subscribers will be authenticated when connecting to this channel:

   • User Roles — Restricts channel access to authenticated users with specific roles. Select User Roles from the dropdown and choose one or more roles from your Catalyst Authentication configuration. Use this when subscribers are authenticated users in your application with defined roles.
   • Custom Logic — Delegates authentication to an Advanced I/O function you define. Select Custom Logic from the dropdown and choose an existing function. Use this when you need custom authentication logic (SSO, API keys, anonymous users, device-based access).

5. Click Create.
   

Your channel is ready to receive and distribute data. You will be redirected to the Test Data Flow section where you can verify that data flows correctly between publishers and subscribers. The Channel ID (required for all SDK and API interactions) is available in the General Details section of the Dashboard tab.
