# Create a party

`POST /parties`

## Request

- Base URL: `https://api.aisle.wedding/v1`
- URL: `https://api.aisle.wedding/v1/parties`
- Auth: HTTP bearer

Creates a party and moves the supplied guests into it atomically. The first supplied guest leads and keeps their RSVP; later members inherit that reply. Empty and single-member parties are allowed. Duplicate guest IDs are refused. A missing or foreign guest, or an active accommodation payment, rolls back the entire operation. Requires write scope and preview access.

## Request body

- PartyCreate
  - `name` string, nullable
  - `guest_ids` GuestId[]

## Response `201`
