Keep Your External Data Current with Change Data Capture | Change Data Capture Developer Guide

When Do You Use Change Data Capture?
You can think of Change Data Capture as part of the real-time data replication process for the cloud.

Change Event Object Support
Change events are available for all custom objects defined in your Salesforce org and a subset of standard objects.

Select Objects for Change Notifications in the User Interface
To receive notifications on the default standard channel for record changes, select the custom objects and supported standard objects that you’re interested in on the Change Data Capture page.

Select Objects for Change Notifications with Metadata API and Tooling API
Use PlatformEventChannelMember in Metadata API or Tooling API to create or retrieve object event selections for the default standard channel or a custom channel. The default standard channel, ChangeEvents, corresponds to the selections that you configure in Setup in the Change Data Capture page. For a custom channel, the selections are set when you create the channel member. The SelectedEntity field in PlatformEventChannelMember represents a selected event.
