How to build an event organizer platform in Bubble

A simple event organizer platform in Bubble is built by defining three main Data Types (User, Event, Registration), building pages to create and view events, and wiring everything with workflows that create Events, let users register, and manage capacity. The core idea is: events are stored as things in the database, users create them with a form, and attendees sign up through a workflow that creates a Registration linked to both the Event and the User.

Core Data Structure

You only need three Data Types:

• User: Bubble creates this automatically. Add fields like "name" (text) and "events\_created" (list of Events).
• Event: Fields: title (text), description (text), date (date), location (text), capacity (number), creator (User).
• Registration: Fields: event (Event), attendee (User), timestamp (date).

This structure keeps things simple: Events don’t store a list of users directly, which prevents scaling issues, and every signup becomes one Registration record.

Creating Events (UI + Workflows)

Build a page "create\_event". Add Input elements for title, description, date, etc. Add a button "Create Event". The button workflow:

• Action: Create a new thing → Type: Event
• Set fields: title = Input Title’s value, date = Date Picker value, creator = Current User
• Navigate to event page (send the new event as data)

Viewing Event Details

Create a page "event" with Type of Content = Event. Add text elements that display "Current Page Event's title", "date", etc. Add a button “Register”.

• Workflow for Register button: Create a new Registration → event = Current Page Event → attendee = Current User.
• Optional: Add capacity check using "Only when: Current Page Event’s registrations:count < Current Page Event’s capacity".

Listing Events

Add a Repeating Group with Type = Event and Data source = "Search for Events". Inside the cell show title, date, and a link to navigate to the Event page using "Current cell's Event".

Admin/Organizer Features

• On the event page, show the list of attendees using a Repeating Group of Registrations filtered by "event = Current Page Event".
• Hide organizer-only buttons using a condition: "This button is visible only when Current User = Current Page Event’s creator".

Example Webhook for External Ticketing

{
  "event_id": "12345",
  "user_email": "[email protected]",
  "status": "registered"
}

You can receive this using Bubble’s Backend Workflow API endpoint and then run an action “Create a new Registration” with event matched by ID.
