You create a Microsoft Graph API subscription to enable Graph API events to flow into a partner topic. The partner topic is automatically created for you as part of the Graph API subscription creation. You use that partner topic to create event subscriptions to send your events to any of the supported event handlers that best meets your requirements to process the events.
