How can I set a cut-off for my guests to RSVP or buy a ticket?

There’s no way to set a cut-off for RSVP events.

If you no longer wish to sell a ticket, enter in a “code” for that ticket and don’t tell people what it is.

To enter a code, go to the “tickets” tab on the event. Then click the ”…” for the ticket and click on “edit ticket”. Then click “visible only with a code” and enter a ticket only you know.
