API endpoint for confirming attendance

Hi there! Do you have any plans of introducing an endpoint for confirming a guest as attended?

The use case is that my organization hosts quite a lot of in-person events with 100-200 event signups, but only 50-70% attendance. To find out who actually comes to the event we could try to check peoples tickets at the door, but that is not always feasable.

So what we would like to do is to display a QR code around the event area so that people can "self confirm" that they showed up. The QR code would go to our web service to collect info about the guest, and then call your API to mark the guest as attended (not just planning to attend, as accepting a calendar invite would be).

Is this making sense? Please let me know if I can clarify something :)
