Hi,
Thanks for the interest in WooCommerce Tickets.
WooCommerce tickets can only be created in events themselves and then show on that single view of the event for purchase. It is possible to edit the ticket product to show on the shop page.
Tickets are added to a cart like any WooCommerce Product and then go through the WooCommerce Purchase Process.
Tickets for the event are generated and emailed once an order is marked complete. By default WooCommerce does not Auto Complete Orders, but there is coding to do that:

Let me know if you have any follow up questions.
Thanks
