You can already point visitors to where they buy tickets for an event — a fully built-in payment/checkout flow on your Mozivio site itself is on our roadmap, but not available yet.
Open an event under Events in the Backstage and fill in the Ticket link field with the URL where tickets are sold — your own external ticketing platform, a payment link, or (once it launches) a Mozivio-hosted checkout. As soon as that field has a value, a Tickets button automatically appears next to that event on your public agenda — nothing else to configure.
Selling paid tickets with online payment fully built into your Mozivio site is planned for a future update. Want to be notified the moment it's ready? Let us know and we'll reach out as soon as it's available.
