API & integrations
Event Registration API
Connect the tools you already use.
Selling tickets or collecting registrations elsewhere? Send each registration to Eventovalley with a simple REST API call. The guest receives their invitation and QR pass automatically, and repeated calls for the same person are recognised as duplicates.

FAQ
Questions about API & integrations
Can I connect my payment page to Eventovalley?
Yes. After a successful payment, send the guest's details and payment ID to the Eventovalley API and they are registered with their QR pass.
What if the same registration is sent twice?
Guests with the same payment ID, email or phone in the event are returned as duplicates instead of being created again.
