# Step 3: Set Up Events

To subscribe to change data capture events on the standard channel, select the objects that you want to receive events for.

1. In Setup, search for `Change Data Capture`, and then select **Change Data Capture**.
2. On the Change Data Capture page, select the object. For example, for this quick start, select the Opportunity object.
3. Save your work.

To subscribe to a custom channel, ensure that the custom channel is created first. After the channel is created, the entities are selected as part of the custom channel creation. See the [*Change Data Capture Developer Guide*](https://developer.salesforce.com/docs/atlas.en-us.change_data_capture.meta/change_data_capture/cdc_intro.htm).

To subscribe to a custom platform event, define a custom platform event on the Platform Events page in Setup.

To subscribe to a standard platform event, including real-time event monitoring events, you can view the available events in the [Standard Platform Event Object List](https://developer.salesforce.com/docs/atlas.en-us.platform_events.meta/platform_events/platform_events_objects_list.htm) in the [*Platform Events Developer Guide*](https://developer.salesforce.com/docs/atlas.en-us.platform_events.meta/platform_events/platform_events_intro.htm).
