# About Events Registration

The Wix Events registration system provides a complete solution for managing event attendance through both RSVP-based and ticketed events. The registration infrastructure consists of multiple interconnected APIs that handle the entire guest lifecycle, from initial registration to event check-in.

These APIs allow you to manage events registration:

- [RSVP V2](https://dev.wix.com/docs/api-reference/business-solutions/events/registration/rsvp-v2/introduction.md): Manage guest responses and attendance confirmations for RSVP events.
- [Ticketing](https://dev.wix.com/docs/api-reference/business-solutions/events/registration/ticketing/introduction.md): Sell and manage event tickets.
- [Event Guests](https://dev.wix.com/docs/api-reference/business-solutions/events/registration/event-guests/introduction.md): Access information about all guests, whether they purchased tickets or RSVP'd.

> **Note:** It's possible for an event to have an external registration, or no registration at all. For more information see the [Events V3 API](https://dev.wix.com/docs/api-reference/business-solutions/events/event-management/events-v3/introduction.md)

## How registration works

The registration process differs based on event type:

### RSVP Events

RSVP events allow guests attend event without purchasing tickets. The flow includes:

**1. Guest registration**

When a site visitor submits an RSVP registration form:

- The system creates a new RSVP record with the guest's response.
- The system sends a confirmation email to the guest.
- If the event has a guest limit and it's reached, new guests are added to the waitlist (if enabled).
- The system tracks the total number of guests per RSVP.

**2. Waitlist management**

For events with limited capacity:

- When a guest list reaches its limit, additional RSVPs automatically go to the waitlist.
- If someone cancels or the guest limit increases, waitlisted guests can be moved to confirmed status.
- Guests on the waitlist receive notifications when space becomes available.

**3. Check-in**

On the day of the event:

- Event organizers can check in RSVP guests using the API.
- The system tracks which guests actually attended.
- Check-in status updates the guest's attendance record.

### Ticketed Events

- For ticketed events, registration happens through the [ticketing system](https://dev.wix.com/docs/api-reference/business-solutions/events/registration/ticketing/introduction.md).

## Before you begin

It's important to note the following points before starting to code:

- The site must have [Wix Events & Tickets](https://www.wix.com/app-market/web-solution/events) installed.
- RSVP settings are configured in the [dashboard](https://support.wix.com/en/article/wix-events-customizing-the-registration-form-for-rsvp-events), including response options ("Yes only" or "Yes and No") and guest limits.
- Events created as RSVP events can't be converted to ticketed events, and vice versa.

## Terminology

- **RSVP**: A response from a guest indicating whether they plan to attend an event, used for non-ticketed events.
- **Guest**: An individual who has registered for or been invited to an event, either through RSVP or ticket purchase.
- **Buyer**: The person who purchases tickets, who may buy tickets for multiple guests.
- **Ticket Holder**: An individual attendee who has been assigned a specific ticket.
- **Waitlist**: A queue of guests waiting for space to become available when an event reaches capacity.
- **Guest List**: A comprehensive summary of all individuals registered for an event.
- **Check-in**: The process of confirming a guest's physical attendance at the event.
- **Attendance Status**: A guest's current registration state (attending, not attending, waitlisted, or pending).
- **Guest Limit**: The maximum number of attendees allowed for an RSVP event.
- **Total Guests**: The number of people covered by a single RSVP (one person can RSVP for multiple guests).
- **Registration Form**: The form guests complete to RSVP or register for an event, which can include custom fields.
