Custom Domains for Event Websites
By default, your event website gets a URL like https://your-event-slug.eventhex.ai/. If you want to use your own domain (e.g., https://conference.yourcompany.com), you can configure a custom domain.
Default Event URL
Section titled “Default Event URL”When you create an event, EventHex auto-generates a free subdomain:
https://your-event-name-XXXXXX.eventhex.ai/The XXXXXX is a short unique event ID. This URL is immediately live — no DNS configuration needed.
Why Use a Custom Domain?
Section titled “Why Use a Custom Domain?”| Default URL | Custom Domain |
|---|---|
society-and-social-69cec0.eventhex.ai | summit.yourorg.com |
| Generic, hard to remember | Professional, branded |
| Free with any plan | Requires a paid plan |
| No DNS setup needed | Requires DNS configuration |
A custom domain gives your event a professional appearance and helps with brand recognition, especially for recurring events.
Set Up a Custom Domain
Section titled “Set Up a Custom Domain”- Choose your domain — decide on the domain or subdomain you want to use. Common patterns:
conference.yourcompany.com(subdomain of your existing domain)summit2026.com(standalone domain for the event)events.yourcompany.com(shared across all your events)
- Configure DNS — add a CNAME record pointing your domain to EventHex:
- Type: CNAME
- Name: your subdomain (e.g.,
conferenceif usingconference.yourcompany.com) - Value: provided by EventHex support (typically a
.eventhex.aitarget) - TTL: 3600 (1 hour) or your DNS provider’s default
- Contact EventHex support to activate your custom domain. Provide your event ID and the domain you configured.
- SSL certificate — EventHex automatically provisions an SSL certificate for your custom domain. This may take up to 24 hours.
- Verify — visit your custom domain in a browser. You should see your event website with HTTPS enabled.
DNS Configuration Examples
Section titled “DNS Configuration Examples”Subdomain of Your Existing Domain
Section titled “Subdomain of Your Existing Domain”If your company domain is yourcompany.com and you want conference.yourcompany.com:
Type: CNAMEName: conferenceValue: <provided by EventHex>TTL: 3600Apex (Root) Domain
Section titled “Apex (Root) Domain”If you bought a standalone domain like summit2026.com:
Type: A Record (or ALIAS)Name: @Value: <IP provided by EventHex>TTL: 3600Multiple Events, One Domain
Section titled “Multiple Events, One Domain”If you run multiple events, you have options:
| Strategy | Example | How It Works |
|---|---|---|
| Subdomain per event | spring.events.co, fall.events.co | Each event gets its own CNAME |
| Path per event | events.co/spring, events.co/fall | Requires reverse proxy (advanced) |
| One domain, redirect | summit.co always points to the latest event | Update CNAME/A record when event changes |
For most organizers, subdomain per event is the simplest setup.
Troubleshooting
Section titled “Troubleshooting”Website Shows “Site Not Found”
Section titled “Website Shows “Site Not Found””DNS propagation can take up to 48 hours. Wait and try again. Use a tool like dnschecker.org to verify your CNAME record is propagating correctly.
SSL Certificate Error (“Not Secure”)
Section titled “SSL Certificate Error (“Not Secure”)”The SSL certificate is being provisioned. This usually completes within a few hours. If it takes more than 24 hours, contact EventHex support.
Website Still Shows Default eventhex.ai URL
Section titled “Website Still Shows Default eventhex.ai URL”The custom domain is set up, but your event’s URL in EventHex hasn’t been updated. Contact support to link the domain to your event.
