Quick help: Settings -> Setup and scroll down to Domains
First you need to point your domain to Confetti through your domain provider. If you are not familiar with setting up domains we recommend you to send this article to you domain provider.
Subdomains (www e.g.) - Most common and recommended!
To setup a custom domain you must do settings both at your domain provider and in Confetti.
Go to the DNS setup for your domain. Then add a CNAME record from the subdomain you want to use (usually www) to cname.confetti.events.
This change usually take a few minutes but it can take a few hours in worst case.
Navigate to Settings > Setup > Domains. Add www.yourevent.com to the list of domains. Your new domain should be primary.
Naked domains (domain without www)
A naked domain is the domain without www or similar in front of it, i.e. yourevent.com. It works a bit different and can't be used with CNAME on all domain providers. Some providers allow you to add a CNAME or ALIAS record for your domain. In that case you point it to cname.confetti.events. just as mentioned above, and then add yourevent.com to Confetti.
One easy way to make yourevent.com redirect to www.yourevent.com is to point an A-record to 188.8.131.52 which will handle this automatically.

Don't put Confetti in an iframe to handle the support the named domain. This will have unpredictable results. When you click the signup-button the url should change to yourevent.com/signup, if not, you're probably using the iframe "solution".
