Obtain Processes That Subscribe to a Platform Event in Metadata API

Use Metadata API to retrieve all processes subscribed to a platform event.

Retrieve all event subscriptions in your org with this sample package manifest.

4      <members>*</members>
5      <name>EventSubscription</name>
6   </types>

In each .subscription file, look at the referenceData parameter. The value is the API name of a process.
