You can integrate the registration component on your custom developed website to have people register, fill out the registration form and pay for their ticket (if you have a paid event, otherwise it's free to register) directly on your custom developed website for the event.
You can also display the agenda of the event on your custom developed website. The agenda will automatically be updated whenever you make modifications in Evenium Net.
Find out how to integrate those components on your website through one of our plugins or with a simple line of code in the back office of your event under Configuration -> External Integration.
