# Withdraw RSVP

> Remove the caller's RSVP from an event

Removes the caller's RSVP. The RSVP row is deleted and the matching `rsvpCounts` entry is decremented. Requires authentication, and the caller must be able to [see the event](/data-models/event#visibility) (otherwise `404`).

Withdrawing is idempotent — withdrawing when there is no RSVP succeeds and changes nothing.

## Path Parameters

<ParamField path="eventId" type="string" required>
  UUID of the event.
</ParamField>

## Body Parameters

<ParamField body="userId" type="string">
  Service/master key only. Withdraw on behalf of this user.
</ParamField>

## Response

Returns the [Event](/data-models/event) with refreshed `rsvpCounts`.

## Error Responses
