Thanks Dana,
I've just done some testing to see how invitation only events work via the Eventbrite UI. It seems that the invitations are sent out with an 'Invite' query parameter which is the key to everything.
Is that parameter value available via any API? If I could access it, I could then send automated emails via our own systems...
Maybe I'll give you a little background on what I'm trying to achieve...
I'm building an app for an organisation which has a paid member base - and some of our events are open to members only, while some offer discount tickets if you are a member. I'm looking for a way to enforce that only members can buy member tickets.
It's possible that the only way to achieve this is via a WebHook and handling exceptions within our own application.
Open to your thoughts.
