# EventRsvp

> The shape of an EventRsvp record returned by the event guest-list endpoint

An `EventRsvp` records a single user's response to an event. There is at most one RSVP per user per event (enforced by a unique `(eventId, userId)` constraint). Setting, changing, or withdrawing an RSVP keeps the event's denormalized `rsvpCounts` in sync.

Individual RSVP records are returned by the named guest-list endpoint ([Fetch Event RSVPs](/v8/api-reference/events/fetch-event-rsvps)). The aggregate `rsvpCounts` are always available directly on the [Event](/v8/data-models/event), and the caller's own status can be surfaced as `userRsvp` via the `userRsvp` include.

## EventRsvp

| Property | Type | Description |
| - | - | - |
| `id` | `string` | Unique RSVP identifier (UUID). |
| `eventId` | `string` | The event this RSVP belongs to. |
| `userId` | `string` | The user who RSVP'd. |
| `user` | `User \| null` | Populated user object. Present on guest-list reads. |
| `status` | `"going" \| "maybe" \| "not_going"` | The RSVP response. |
| `createdAt` | `string` | ISO timestamp when the RSVP was first created. |
| `updatedAt` | `string` | ISO timestamp when the RSVP was last changed. |

## RsvpStatus

The set of valid RSVP values, which also map to the keys of `Event.rsvpCounts`:

| Value | Description |
| - | - |
| `"going"` | The user plans to attend. Counts toward `capacity`. |
| `"maybe"` | The user might attend. Only allowed when the event's `allowMaybe` is `true`. |
| `"not_going"` | The user has declined. |

## Lifecycle

* **Set / change** — `POST /events/:eventId/rsvp` with a `status`. Creating or switching to `going` is capacity-checked under a row lock.
* **Withdraw** — `DELETE /events/:eventId/rsvp` deletes the RSVP row and decrements the corresponding count.
* **Removed on invite revoke** — if a host removes an invitee from an `invite`-only event, that user's RSVP is deleted and the count decremented.
* **Removed on user deletion** — deleting a user removes all their RSVPs and decrements affected events' counts.
