Hey @Math,
That’s a really interesting question and one I’m surprised I haven’t seen come up yet.
I’m afraid that Event Tickets Plus currently does not support embedding tickets on other websites. That said, I think it’s a really cool idea and one I would strongly suggest adding to our feature request forum if you have a chance — I can see how others would benefit from that (more ticket sales!) and submitting the idea will help us get the idea on the radar and see what kind of interest it would get.
Sorry for the bad news, but does this at least help answer your question? Please let me know.
Cheers,
Geoff
