Creating events

Set up the foundation of your event — title, URL, format, dates — in a single form. Everything else is added later once the event exists.

Updated May 26, 2026


An event in Mercleo Events is created in a single form, then expanded over time. The form captures the minimum needed to give the event a home — a name, a URL, a format, and optionally some dates. Everything else (tickets, branding, schedule, communications) is configured on the event's own tabs after the event exists.

Open the New event form

From the Events home, click New event. The form opens at /events/new as a full page, not a modal — drafts persist if you navigate away and come back, but only after you submit.

Fields on the form

  • Title — required. The public name of the event. Minimum two characters, maximum 255.
  • URL slug — required. The URL-safe identifier that becomes part of your public event URL. Lowercase letters, numbers, and hyphens only. Auto-derives from the title until you edit it manually; once edited, it stops following the title. Must be unique within your workspace.
  • Description — optional. Up to 2000 characters. Shown on the public microsite under the event title. You can leave this blank and add it later.
  • Visibility — public (anyone in your workspace can see and edit) or private (only invited team members can see it). This is workspace-level visibility, not attendee-facing visibility — both options let you publish a public registration page.
  • Event format — simple, multi-session, or conference. Determines which features are available for this event. Locked options depend on your account plan. See the dedicated article on event formats for details.
  • Start date and End date — optional on the create form. You can finalize timezone, venue address, and detailed scheduling on the Setup tab after the event exists.

The URL slug is permanent once the event has any registrations or shared links. Choose carefully — changing it after the event is published breaks every link you've sent and every embed widget pointing at the event.

What happens after you create

The event is created in draft status. Draft events are visible to your workspace team but not to the public — the registration page returns a not-found error to anyone outside your workspace until you publish.

You're returned to the Events home page, where your new event now appears in the list. Open it to start adding ticket types, branding, custom questions, and everything else.

Editing the basics after creation

Most fields from the create form remain editable on the event's Setup tab, with two exceptions:

  • URL slug — editable, but only safe to change before any registrations exist or any links have been shared.
  • Event format — can be upgraded later (simple to multi-session, or to conference) if your plan supports the target format. Downgrades are not allowed once features tied to the higher format are in use.
