Hi there, Houman! Thanks for getting in touch.
Good question. Transactions are actually handled through WooCommerce instead of WooTickets, so you would need to configure that behavior on the WooCommerce side of things. For example, here is a WooCommerce forum thread that looks like it covers exactly what you’re looking for. I would suggest going that route and following up in the WooCommerce forums if you have any follow-ups.
Does this help answer your question, at least on the WooTickets side? Please let me know. 🙂
Cheers!
Geoff
