Accessing an occurrence using an occurrenceId

Question

Hello Microsoft Team,

I'm building a calendar integration with Graph API and I'm currently working on recurring events. During this process, I found out that you can get a specific instance of a recurring event using an occurrenceId (OID.{masterId}.{date}) in a GET request, instead of the event ID of the occurrence.

As I could not find any documentation about this usage, can you tell me if this is officially supported and if I can rely on it in a production setting?

Best,

Sylvain
